How to install plastic windows in a log house. How to install plastic windows in a wooden house


Plastic windows can be installed in any kind of structure: stone, concrete, wood. But installation in a wooden structure requires more attention, since wood is prone to shrinkage due to drying out. Wood that dries turns into a strong press that can deform the window block. As a result, the window structure ceases to function correctly and may become askew. Let's look at how to avoid this situation and install windows without errors. Let us dwell on the specifics of window construction made of polyvinyl chloride, its strengths and weaknesses.

Advantages of PVC windows

PVC windows are window structures made of polyvinyl chloride. This material is a chemical synthetic based on petroleum ethylene and chlorine. This polymer is resistant to various influences and lasts a long time. Window structures made from the specified material are resistant to:

  • sun rays;
  • high humidity;
  • exposure to insects;
  • exposure to organisms invisible to the eye.


PVC for window structures is a rigid and durable material. The strength of the polymer is several times greater than that of wooden structures and can withstand changes of one hundred degrees - from fifty degrees below zero to fifty degrees above zero.

Polyvinyl chloride consists of the following components:

  • stabilizers;
  • modifiers;
  • dyes;
  • fillers;
  • lubricants


The material lasts a very long time, manufacturers give a twenty-year guarantee, but it is still impossible to verify whether this is true. The service life of the first installed windows has not yet passed. Statements that even after fifty years windows will not lose their properties are possibly real. But window seals fail much faster. As practice shows, they need to be changed every eight to ten years. In general, the service life of the seal depends on the temperature of each specific area.

Among the advantages of plastic structures are the following:

  • high quality material and resistance to various types of influences;
  • tightness of the structure - while staying in the room, a person is reliably protected from noise, dust, gases and harmful substances;
  • high sound insulation ability - windows can significantly dampen extraneous sounds;
  • reliable thermal protection - complete protection from drafts and reliable heat retention;
  • efficiency - saving heat resources;
  • attractiveness of designs - you can use not only standard windows, but also bring design ideas to life.


Basic properties of window structures made of polyvinyl chloride

Supporters and opponents plastic windows There are disputes about the safety of these structures for health. Those who claim that structures are unsafe for human health argue that this is due to the presence of lead in the base of the raw materials. But lead in windows is completely safe, and most manufacturers have replaced this material with others. The fact that PVC window structures are quite economical and environmentally friendly is confirmed by certificates:

  • thanks to PVC windows, heat is retained in the room and this saves resources and money;
  • Plastic structures save wood resources and thereby prevent deforestation.

In some countries, the government pays money to residents who install plastic structures for their personal contribution and concern for saving natural resources.

Opponents of plastic structures argue that over time, plastic becomes unsightly, as it turns yellow and fades. But nowadays the technologies for the production of plastic windows have improved and the color is not lost under the influence of natural forces.

In the event of a fire indoors, window structures of this type will “hold” the fire, since the plastic structure has high thermal insulation abilities.


Types of plastic windows

The construction segment offers a huge variety of plastic windows. They differ in many ways: shape, size, number of sashes, options for opening them, types of double-glazed windows, types of profiles. Currently, manufacturers present windows with various types of decoration, to varying degrees transparency.

Based on the number of sashes, windows are divided into one, two and three-leaf windows. The chosen option depends on the location, the size of the structures and the individual characteristics of the home. For a small window it will be convenient to have one sash. For typical apartments, it is recommended to install windows with a pair of sashes.

Regarding opening windows, the following options are distinguished:

  • a blind design is the most ill-conceived window regarding its functional tasks;
  • rotating elements;
  • folding elements;
  • combined elements.


Its operational capabilities depend on the characteristics of the profile. PVC itself has low thermal conductivity, but chambers with air inside the structure help retain heat several times better. The thermal conductivity of the window and the air temperature in the home depend on the number of chambers. There are from three to seven cameras.

Three-chamber windows are installed in rooms that do not require heating: outbuildings, sheds.

As for six and seven chamber windows, they do not perform their functions better than four or five chamber windows, so there is no point in overpaying for the design.

As for marking profiles with letters, there are types: A, B and C. Type “A” is used in homes. “B” and “C” are recommended for use in factory or warehouse premises.

The glazing of the structure itself can be done using two, three or four sheets of glass. They are fixed at the required distance from one another and form chambers.

Double-glazed windows can be one, two or three-chamber. This point can be confusing when buying a window. It is necessary to clarify which cameras are meant in the frames or double-glazed windows themselves.


Plastic structures for wooden houses

With the installation of plastic windows in wooden walls you will have to study the theory of the issue to do everything correctly. Some people think that it is impossible to install plastic windows in old wooden buildings. But in fact, no, this can be done in any type of premises. You can install windows yourself, provided that you have minimal knowledge of construction basics. The main thing is to take into account the characteristics of wood as a material and take into account the fact that the wooden frame of a house can also sag.

After you have selected windows for a wooden house, you need to familiarize yourself with the “jam” technology. This technique is aimed at preventing deformation of window structures, regardless of the selected material.

Statistics show that a wooden house shrinks up to thirty-five centimeters. Depending on the foundation of the structure, twelve months after the construction of the house it settles in any case; this is a natural process. The maximum error will be provided that the house is built from rounded timber, the minimum - from laminated veneer lumber. An ordinary beam can sag by thirty to forty centimeters. This is taken into account as a factor that can deform window structures. Deformation may manifest itself in the impossibility or difficulty in opening and closing the window.

Builders advise not to install plastic structures in new houses until it shrinks. But as experience shows, old buildings can also cause windows to become deformed. But what to do, is it impossible to install plastic metal structures in wooden houses? In fact, experienced builders have developed installation technology that will allow you to use PVC windows to their full potential.


Installation instructions for plastic windows

For successful installation work, it is important to plan and carry out competent preparatory work; they consist of the following actions:

  • it is necessary to dismantle the old window structure;
  • clean the recesses from construction waste and dust;
  • correctly measure the window opening, write down the calculations;
  • If the window opening does not match the dimensions of the new window frame, it should be adjusted to the dimensions using special solutions for working with wooden surfaces.

At the preparatory stage, a decision is made on the shape of the window, the number of sashes, in what color scheme it will be in how many packages.

When all decisions have been made, double-glazed windows are ordered according to the requirements.

The pigtail is the next stage in installing a metal-plastic structure.



The window structure can be finally installed in a wooden structure after preparing the frame. This is a structure made of wooden beams, aimed at supporting the weight of load-bearing walls and preventing the window from deforming. The required timber size is ten by fifteen centimeters. Using a chisel, connecting grooves are made on these bars, about five centimeters wide. Cuts are made longitudinally using a chainsaw. All manipulations are controlled by the building level.

Plastic structures are inserted into the prepared pigtail system and secured with fasteners. The installation procedure is as follows:

  • with the help of fasteners the pigtail system is fastened into a single frame;
  • a small distance is left below using a wooden wedge;
  • a window frame is inserted into the system of the manufactured frame and secured with fastening structures;
  • pre-removed window sashes are installed;
  • all gaps must be filled with foam;
  • the wooden wedge placed previously is removed.

A pigtail specially installed in a wall made of wooden material, performs several important tasks:

  • does not allow the wooden structure to move vertically;
  • does not prevent the log from shrinking vertically;
  • strengthens the wall at the window opening.

Experienced builders insist on installing a frame even when installing plastic windows in an old wooden house. They argue that this measure is simply necessary. A structure made of wood constantly changes its size to one degree or another - it swells during rain, and dries out during heat.


Tool for installation of plastic structures

The most important process is the process of installing plastic structures in their intended place. To do this, it is advisable to prepare in advance all the tools that will be needed during the installation of the structure:

  • drill for woodworking;
  • screwdriver;
  • fastenings: anchor bolts and plates;
  • polyurethane foam;
  • spray bottle with water.

Naturally, during work you will need other tools. Ideally, such work should be carried out with a partner who can supply the tool and hold the structure when necessary.

Installing plastic elements is a difficult type of construction activity. If you are installing plastic windows yourself, take into account all the recommendations of specialists.


Calculation of plastic windows

Correctly calculating the dimensions is not easy; it is a very difficult process that is best entrusted to a professional from a window workshop. Recently, an online calculator for plastic structures has appeared, allowing you to find out the exact cost. It is very comfortable. The sites offer various filters:

  • you can choose the layout of the future window structure;
  • decide on the configuration;
  • in the configuration, a choice is made by type, profiles, types of double-glazed windows;
  • after that, just click on the button and the plastic structures will be calculated.

The cost of window structures is affected by the number of sashes, the choice of additional fittings, additional functions of the double-glazed window, and profile color.

To imagine how plastic metal structures are installed in practice wooden houses, watch the video. In fact, you can install windows on our own, for this you need to take into account the specifics and features of this method and follow the recommendations of specialists.

The wooden house is distinguished by its beauty outside and pleasant atmosphere inside. But it is impossible to make your home ideal without structures such as windows. Before you install them, you need to understand which material is best suited for this. For many years now, people have been actively using plastic windows. They go well with wood, while reducing heat loss, increasing sound insulation and giving the structure a finished look. It is also worth paying attention to this. how it happens

Before purchasing PVC windows, you need to decide what they are made of. Such information will allow you to perform high-quality installation of plastic structures. So, the main elements of PVC windows remain:



Here's what wooden window shutters look like and how they can be installed. can see

When choosing a PVC window, you should pay attention to the size. According to the standard for plastic windows, the size of the window structure will be 1200x1200 mm.

Installation process

Process PVC installation windows in wooden house requires strict adherence to technology. The first step is to carefully take all measurements. First determine the distance from the floor to the window sill. To do this, you will need to take into account the height of the person. Equate the resulting distance to 80 or 90 cm. When taking measurements, it is necessary to take into account the comfortable distance to the window. The window sill should be higher than the dining table or desk. When everything has become clear about the location of the window sill, it’s worth moving on to inserting the openings. They will be 5 cm below the window sill. This distance must be ensured for polyurethane foam

. It is also worth paying attention to how you can produce Cut the opening using a level. Using a plumb line, mark vertical marks. The upper limit is determined taking into account the height of the structure. PVC frames suggest an increase in the opening by 14 cm above the window structure.

The width of the opening should also be 12 cm larger than the frame. When the preparation of the openings and casing is completed, you can proceed to the installation of double-glazed windows. In this case, it is worth considering one basic rule - you cannot drill through the frame, as this can break the tightness and thermal insulation. It is best to use special fasteners for this. Simplify installation work

It is possible if you remove the sash from the frame. This makes it possible to lighten the design.

It may also be useful for you to learn more about what material should be used.

The frame installation process is carried out using a level. This will give you the opportunity to get it correct landing. After installing the frame, you can proceed to fixing the slopes. At the same time, do not forget about the gaps for the polyurethane foam. When the frame is already installed, you can pick up a gun with polyurethane foam and walk it around the perimeter of the opening.

When installing PVC windows in a wooden house, you must take into account the following features:



Design and finishing

After the installation of the plastic window is completed, care must be taken to ensure that the built-in structure has an attractive appearance. For these purposes, you will have to perform finishing, which includes installing slopes.

They can be either plastic or wooden. Let's consider the process of installing PVC panels:

  1. External and internal cladding begins with the fact that the starting strip is fixed around the entire perimeter.
  2. The panel itself is fastened using self-tapping screws. They need to be screwed in with a screwdriver at the bottom and top of the structure. Then you can use the corners to disguise them.
  3. The panel at the top of the opening is installed in the same way. When the width of the slope exceeds the width of the panel, several elements can be used. They are fastened using tongue-and-groove technology. Each joint of this design must be thoroughly treated with sealant. This way, moisture will not penetrate through the joints.
  4. Once the installation is complete, you need to start attaching the corners. To do this, you need to use assembly glue or liquid nails.

But this will help you understand how to insulate a plastic window for the winter.

Video of the design of a plastic window in a wooden house:

If you decide to use wooden slopes, then you will get an attractive design for PVC windows. But when choosing a material, make sure that it combines favorably with the appearance of the entire house. In a wooden house, slopes made of wooden lining look great. This design option is in great demand today and for the following reasons:

  1. Wooden lining is available in a wide range of sizes and colors, so there is a good option for every occasion.
  2. Lining is an environmentally friendly material, so there is no need to worry about safe living in the house.
  3. The lining has excellent strength characteristics, a long service life while maintaining a presentable appearance.

But how to adjust plastic windows and what tools are needed will help you understand this

The process of installing lining is not complicated, so even an inexperienced person can cope with such work.

To do this, you just need to follow the following sequence of actions:

  1. Fix a starting strip along the perimeter of the slope.
  2. By analogy with the installation of PVC panels, wooden products are also being installed. The lining is fastened using self-tapping screws.
  3. All fastener defects can be masked using corners.

After installation, it is important to understand how to do this work yourself.

Cost of windows and installation

You can buy a PVC window today at a price of 3000-6500 rubles per piece. But professionals can install a window at a price of 800 rubles per m2.

The popularity of PVC windows is growing every year. And this is not surprising, because such designs have a presentable appearance, long service life and excellent noise and heat insulation properties. Even windows installed in a wooden house will blend favorably with the building and perform their tasks perfectly.

In our wooden house, we decided to replace the old wooden windows to modern plastic ones. This article discusses in detail the installation of double-glazed windows with your own hands in a wooden house. The article is based on personal experience. Why is it profitable to install windows yourself:

  1. When installing double-glazed windows in a wooden house by a supplier or manufacturer, the cost of the window along with installation will cost 40-50% more than its original cost.
  2. As a rule, about 95% of companies that install windows do not guarantee the quality of installation in a wooden house. Therefore, when you install plastic windows in a wooden house yourself, you do not lose the warranty period, but only save for your own benefit.

For example, if the cost of a double-glazed window is $184, the fee for removing the old window and installing a new one will be approximately $92. That is, the total price of the window will be $275. If you replace all the windows in your home (approximately five), the savings is $459!

Window installation is shown in the example self-installation double-glazed windows, without the help of outsiders, which takes an average of two and a half hours (for one window). The following describes step by step the process of inserting a plastic window into the window opening of a wooden house.

Removing old windows

Self-installation of double-glazed windows in a wooden house is carried out on a solid foundation (frame). Since in our example, the window boxes were installed quite recently (about 5 years ago) and were without damage (cracks, chips, rotten formations and wormholes), we decided to use them instead of a frame for installing new windows.

Important: all measurements for window installation must be made taking into account that the window frames remain in the same place.

Old window frames that are in good condition and strong enough can be reused, for example, to install a greenhouse. Therefore, in order not to damage the wood of the frame, they must be dismantled carefully; it also does not hurt to remove the glass from them before doing this. In our case, we did not remove the glass from the frame, since the durable frames did not warp when removing them and were dismantled quite easily.

Preparing a site for installing double-glazed windows

With a dry and clean rag (or soft brush) you need to wipe the window frame and remove the waste and debris that has accumulated after dismantling.

The PVC window sill is installed first, since it is the base of the double-glazed window when it is installed. In this regard, the window sill should be installed as level as possible (ideally horizontal). We check the exact horizontal installation of the window sill with a level, both longitudinally and transversely.


To ensure that the window sill stands firmly, we make cuts up to 8 mm deep on the sides of the window frame. To adjust the evenness of the window sill, we use special plates made of plastic or fiberboard, or thin wooden planks treated in advance with an antiseptic. After the final installation of the window sill, we measure the evenness of the window sill with a building level.

We fasten the window sill with self-tapping screws to the bottom of the window frame, while making a 2 cm indent from the outer end of the window sill. When tightening the screws, we place washers under their heads in order to protect the surface of the window sill from damage, which is possible if it is broken through by the self-tapping head (at PVC window sills have cavities). After the window is completely installed, the places where the window sill is attached will not be visible, since they will be hidden from view.

Preparing a plastic window for installation

At the very beginning, even before installing the window, you need to install the handle. There is no need to remove all the protective film from the window surface yet, as it protects the window from possible mechanical damage. The protective film is removed only in the place where the handles need to be installed. When installing them, the handle handles must be in a horizontal position (as shown in the photo). This position means that the window opens on its side, and if the handle is turned down, the window will be locked in the closed state, but if the handle handle is turned up, the window will open in the crank mode.

We fix the handle to the window with two bolts and move the handle handle down. On the side posts of the window (at the ends) we make markings for making holes on which the window will be fixed to the block. Next, using an electric drill, we drill two through holes (lower and upper) along this marking in the right pillar of the double-glazed window and in the lower pillar (4 holes in total). The distance between the bottom and top parts of the glass unit to the hole should be from 25 to 35 cm. The diameter of the drill for this work should be 6 mm, while the diameter of the screw is 5 mm.

To ensure that the head of the screw rests firmly on the window frame, we use side posts with inside We drill holes for fastening with a drill with a large diameter - 10 mm, right up to metal frame. The hole should be such that the head of the screw fits freely into the cavity of the window post.

Window installation

We install the assembled window into the window opening. We control the center using measurements taken with a tape measure starting from the edge of the window and ending with the surface of the window frame on both sides; the distance should be the same (about 1 cm). We install the window on the surface earlier installed window sill. Since we have already checked the window sill for levelness using a building level, there is no need to check the window itself for horizontalness.

To install a window parallel to the wall of the house, we install a building level between the wall and the siding for support. If the house was sheathed differently finishing material for example, clapboard that fits tightly to the wall and does not allow you to place a level, then you need to use a plumb line for control.

We install a spacer bar 1 cm wide between the window frame and the window. It is necessary that this block fits tightly enough between the window frame and the window. This block is needed as a stop at the moment when the window is attached to the window opening using self-tapping screws. If this is not done, then the window may move to the side when it is fastened (it will simply be pulled away) and at the same time the mechanism for opening and closing the window will not function well, or the window sash will not open at all.

When the installation of the stop bars is completed and the window is aligned with a level or slope parallel to the wall of the house, then we fix the double-glazed window with self-tapping screws. We fix the window to the window frame from the bottom and top of its side posts, so that the self-tapping screw is in the free space between the frame and the window.

Such fastening of a double-glazed window is not only reliable, but also provides a floating effect. If there are seasonal shifts in the structure of the house, warping the window openings, then windows that are not rigidly attached to the frame are almost not subject to warping, due to the fact that the self-tapping screw can arbitrarily move in the direction of the skew of the window frame.

First, install adjusting plates between the drain holes. This is necessary so that the glass unit does not cover the openings through which condensation is drained from the window.

Carefully install the double-glazed window into the window opening. We make sure that it does not fit tightly between the window posts, since if seasonal changes occur and, accordingly, distortions of the window frame, the glass in the double-glazed unit may burst.

If your glass unit fits tightly, and there is no gap between the window mullions and the glass unit (at least 5 mm), then you should seek an explanation from the company that made the glass unit according to your order, so that the company’s employees can eliminate this deficiency. It is necessary to check the gaps between the frame and the glass unit before removing the old window.

We install the double-glazed window evenly and fix it with plastic beads, which have profile tenons that are inserted into the grooves of the window frame by lightly tapping the beads, when the tenon goes into the groove and a click is heard. A click means the staple is securely fastened.

After the window is installed, we fill the void between the window frame and the window with foam for installation, both from the inside and from the outside. outside Houses. Excess hardened polyurethane foam is cut off with a sharp knife.

After this, you can begin finishing with platbands, fittings and drainage.

Many people believe that installing a plastic window in a wooden house is a very difficult set of works. This is due to the fact that wooden houses undergo natural shrinkage over time. But if you know the installation features and follow some rules, then in fact there is nothing impossible about it.

What to consider during installation
Configuration of window openings in wooden buildings, although imperceptibly, constantly changes throughout the entire period of operation. This is due not only to the shrinkage of wood, but also to its ability to become saturated with moisture and deform due to temperature changes. That is why the parameters of openings in such buildings are characterized by instability.
The recommendations that the installation of plastic windows can be done 3 years after the construction of a wooden building are not entirely correct. Shrinkage occurs in stages. The bulk of the moisture evaporates in the first year, but the process of “shrinkage” continues for several years. Experts note that basically this period is an average of 5 years, and in some regions (taking into account the climate) it never ends. This imposes special requirements on the arrangement of such a structural element as the frame, which is mounted when installing window frames.

Installation procedure
Preparation
If the house is new, then you need to check the geometry of the window opening. Even if all dimensions were strictly maintained during the construction process, some distortion may occur as a result of shrinkage. PVC windows are not like that. They are a rectangle of strict shape, without any deviations. Therefore, it is necessary to achieve the correct configuration of the window opening (if the distortion is significant). There are many techniques, and they are not complicated.
The same applies to a house that is already in use. After removing the previously installed window, the installation site of the plastic window is inspected.
It is necessary not only to clean everything from dirt and level it, but also to carry out high-quality treatment of the wood with antiseptic and fire retardant compounds.

Installation of a casing
This structural element is mounted in the window opening, regardless of the material from which the frame (window block) is assembled. It is inside such a frame that it is attached. The purpose of the casing is to eliminate the influence of the deformation of the walls of the house on the window, to make it “independent” of various displacements and arising mechanical loads, and to maintain its integrity. In other words, no matter how the geometry of the opening changes (shrinkage of the walls, settlement of the foundation), this should not affect the frame itself.
There are several options for casing construction. The choice of the optimal one depends on the type of workpiece (timber, log), their characteristics and a number of other conditions. By the way, not all frame designs are suitable for PVC windows, and this must be taken into account.
The casing “assembly” should be smaller than the window opening to prevent its destruction due to vertical displacements of wall elements. As an example, let’s consider the simplest, and therefore often used, version of the pigtail, which is suitable for “plastic”. Necessary tool Each owner will choose for himself. The main thing is to understand the principle of arrangement and operation.
At the ends of the sidewalls of the opening, vertical recesses (grooves) are cut along the entire height. Carriages will be inserted into them with their protrusions, which are a piece (according to the size of the opening) of a thick board, along the center line of which a “spike” is located. With vertical displacements of the walls, the protrusion will slide along the “groove”, and the casing itself (and therefore the window) will not undergo deformation.
Another option could be this - “spikes” are made on the end parts of the beams (logs), and the grooves are cut out in the carriages. But the principle of operation is the same.
The lower (supporting part) is made so that it has “spikes” on both sides, which are inserted into the grooves of the sidewalls of the opening. The upper part of the frame is made by analogy. It is fastened into a single structure using self-tapping screws and dowels. The main thing is that the casing should not be fixed to the wall, then the meaning of its installation is lost.

Window installation
The PVC frames have special fasteners with which they are fixed to the frame. When purchasing window units, you need (at the point of sale) to figure out how this is done, since different Manufacturers may have different fastening designs.
When placing the window in the frame, you need to slightly lift it and fix it in this position (place wood chips) so that a small gap is formed (for further “foaming”).

Sealing
All gaps between the block and the pigtail box are sealed with polyurethane foam. Moreover, their processing is carried out on both sides (inside and outside the building). After complete drying, it is easy to trim off the excess.

Practical recommendations
"Plastic" is quite sensitive to low temperatures- it becomes brittle. Therefore, installation of such products at -10 0C and below is not carried out.
There is no point in purchasing PVC windows until casing is installed on all openings. It is their geometry that determines the size of the plastic blocks. All the rules for choosing a quality window are described in this article - read on.
The dimensions of the “tenons” (“grooves”) are usually chosen to be about 5 cm.
It should be taken into account that ultraviolet radiation is destructive for polyurethane foam, so such a “filling” must be somehow protected.
