Installing plastic windows is not a very labor-intensive job. Therefore, each person can independently begin installing plastic windows. But anyone who decides to install windows themselves is faced with the problem of choosing fasteners. After all, there are many types of fasteners on the product market. And every novice builder wonders.

What fasteners are best to choose for window installation? To answer this question unambiguously, let's look at this issue thoroughly. And we will consider the types of fasteners for plastic windows, as well as installation rules and characteristics.

Types of fastening elements for windows

  • Anchor dowel
  • Anchor plates
  • Nog

Now let's pay attention to their features.


Anchor dowel

This type of fastening for plastic windows is very reliable. The principle of operation is designed in such a way that when the screw is tightened, the bushing expands the walls of the sleeve and the element is securely fastened.

Size. There are a huge number of dowel sizes from 100 to 200 mm, and their thickness is from 7-12 mm. To calculate your dowel length, you need to measure the thickness of the window and opening from the frame and slope.

Typically, the thickness of the frame varies about 4-6 cm, and the dowel should enter the wall at a distance of 4 cm. If your distance from the wall to the window is about 3-4 cm, then you need a 110 mm dowel, if 8-10, then 160- 190 mm.

Flaws. The disadvantage of any type of fastening is that once the dowel is installed, it can no longer be dismantled. Therefore, you need to take window alignment very seriously, because... correcting your mistakes will cost you a lot and take a large number of time.

Also, if you hit the reinforcement with a drill, you can break the drill and have to drill a new hole.

Important. Before installing a plastic window in an apartment panel building, you need to find out its type and wall structure. Because in many panel houses Builders install insulation inside the walls. Therefore, during installation you may get caught in the insulation and the dowel may fall out. Also, do not install the dowel in soft building materials.

The depth of drilling inward for the dowel depends on the material from which the wall is made. IN concrete wall the depth is 4 cm, and in brick wall 7-8 cm.


Nog

A dowel is a simple screw that is screwed into the wall to secure a window. This type of fastener is also very reliable. Unlike a dowel, the dowel can be easily unscrewed in any case.

Dimensions. There are a huge number of dowel sizes from 100 to 250 mm, and thickness from 5-12 mm. To calculate the length of the dowel, you need to measure the width of the window and opening from the frame and slope. If your distance from the wall to the window is about 3-4 cm, then you need a 110 mm dowel, if 8-10, then 170-200 mm.

Flaws. Before installing a plastic window in an apartment panel building, you need to find out its type and wall structure. Because in many panel houses, builders install insulation inside the walls. Therefore, during installation you may get caught in the insulation and the dowel may fall out.

You should also not install the dowel in soft building materials.

Important. The depth of drilling inwards under the dowel depends on the material from which the wall is made. In a concrete wall the depth is 6 cm, and in a brick wall 7-8 cm.

Anchor plates

This type of window fastening is suitable for panel houses in which there is insulation and the use of anchors and dowels is impossible. It is also perfect for wooden houses and baths, where it is not possible to fix windows in the wall. By filling the free space with polyurethane foam, this design will be very reliable and warm.


Dimensions. The length of this fastening element varies from 150-200 cm. One edge of the plate is secured with a self-tapping screw to the frame from the outside, and the other is secured to any load-bearing structure for two self-tapping screws. The length of the second part should be around 10 cm.

Flaws. This type of fastening is not the most reliable.

Important. This method of fastening is the most common, because... it is the simplest. It is mainly used by beginning builders. The anchor plates should be located at a distance of 15-20 cm from the corners of the window opening and at a distance of 60 cm from each other.

I cannot say which type of fastening of plastic windows is the best. Each type has its own disadvantages and advantages. You must choose the type of fastening yourself, depending on the technical features your house.

Photos of fasteners for plastic windows



Coziness and a comfortable microclimate at home are created primarily not by interior items, furniture and textiles, but by quality installed windows. Correct installation eliminates the occurrence of drafts, accumulation of moisture and the appearance of fungus on slopes and walls.

The choice of fastening elements is based on the wall material and the design of the window opening. These can be construction screws, anchor bolts, expansion metal or plastic dowels, anchor plates.

Anchor plate options

Anchor plates are used for installation as metal-plastic windows and wooden double-glazed windows. Any window installation technology has the main goal of redirecting all force influences (wind, window weight, building load) from the plane of the glass unit to the wall.

The plate is a metal strip 25-30 mm wide with guide notches along which it bends during installation. The plank has several holes for fastening with anchors (screws, self-tapping screws) in the desired position. Plates are stamped from thin sheet steel with a thickness of 1.2 mm, 1.5 mm, 2 mm in various modifications and treated with an anti-corrosion zinc coating. It is important to select the right size anchor plate for each profile.

Features of using plates and their types

Fastening to an anchor plate has no alternative when installing a window profile in an opening with a “loose” wall component - these are three-layer walls, adobe blocks, wooden beams, hollow brick.

There are two types of anchor plates:

  • rotary;
  • non-rotating.

Plates with a rotating unit are used if fastening in the opening itself is not possible. Installation on a rotary anchor is used for arched, trapezoidal and polygonal windows.

A conventional fixed anchor is designed to fasten a window in an opening, but the angle of fastening can also vary.

Advantages of anchor plate

The ability to quickly create a strong and, at the same time, elastic connection between the window and the wall using a plate is the main advantage of this type of fastening. Seasonal and daily temperature deformations of the window do not affect the durability of the installation of the anchor plate.

Other advantages of anchoring a window to a plate:

  • There is no need to disassemble the profile and drill through it;
  • possibility to select the attachment point;
  • ease of leveling the window plumb or level;
  • absence of large mounting holes;
  • preventing natural moisture from entering the profile and seam;
  • when dismantling the window, the plates are easily unscrewed, unlike anchor bolts;
  • the window can be reinstalled again;
  • low cost of fastening;
  • Window installation time is halved compared to installation with bolts.

The advantages of installing windows on anchor plates are so tangible that they are used everywhere when working with any wall materials.

The only case where this type of installation may not be acceptable is when installing very heavy balcony sections to the full height of the wall, or placing several rows of windows directly above each other. In this case, the planned load on the fastenings may be too high and the anchor plates should be placed on the anchor bolts.

Installation of PVC windows on anchor plates

Installation of PVC windows or balcony blocks begins with calculating the operating load. The type of opening and closing of windows affects the supporting force, the overall traction effect on the hinge mechanism and determines the required number of plates for installation. Having prepared all the consumables, we proceed to installation:

  1. Remove the shipping film from the outside of the window frame;
  2. Install the toothed “claws” of the anchor plate into the special protruding parts on the profile. Use a self-tapping window screw as an additional fastening.
  3. Screw the plates around the perimeter of the entire profile, maintaining a distance of 150-200 mm from the corners of the frame. The further distribution step of the plates is 500-700 mm.
  4. Bend the plates at the places of the notches so that the first fold is at the junction with the frame, and the second at the place of attachment to the window opening.
  5. Place the frame on rigid supports. They should be not only in the corners, but also under each section of the window. Use wedges to secure the frame vertically.
  6. Using a level, accurately adjust the frame in all planes and firmly secure the plates in the opening using two anchors.
  7. Moisturize the area assembly seam water using a spray bottle.
  8. Produce internal thermal insulation assembly seam using polyurethane foam. Take into account its expansion properties so that it does not protrude onto the profile itself. For internal insulation The following materials are also suitable: construction sealant (mastic), vapor barrier sealing tapes based on butyl material.
  9. Creation of an external insulating layer: finishing slopes with plaster or facing with dense protective materials (stone tiles, facade bricks).

Video about installing a window on anchor plates

Hello readers! I haven't written on the blog for a long time. The season for installing and adjusting windows before winter has begun. Everyone wants to stay warm.

So, many clients are interested in how we attach plastic windows. I’ll say right away that there is no single fastening.

It all depends on where the window is installed. Therefore we can use anchors or plates. In general, I got tired of answering the same questions and I decided to put them in one article, a link to which they will give to all their new clients.

I hope you find this information useful too. Read, get acquainted.

The choice of fasteners for windows primarily depends on the material of the wall into which you will mount your window:

  • Brick;
  • Tree;
  • Aerated concrete, foam concrete, cinder block;
  • Concrete.

Secondly, on the type of construction and technical specifications installation:

  • Loggias;
  • Entrance doors;
  • Window;
  • Stained glass.

How to fix plastic windows. Types of fasteners

1. Anchor or frame dowel. It comes with a diameter of 8 mm, but practice shows that the optimal diameter of the frame dowel is 10 mm. In my opinion, the most reliable and convenient fastening for windows.

Available in different lengths: 72 mm, 92 mm, 112 mm, 132 mm, 152 mm, 182 mm, 202 mm. Used as follows:

IN window frame a hole is drilled using a metal drill with a diameter of 10 mm. Then, using a hammer drill, a hole is drilled in the concrete, directly through the frame.

I consider this optional. Therefore, as for the dowel head, there is even a special decorative plug. And the fastening strength in both cases is almost the same.

For each type of window profile, especially popular ones, a certain type of anchor plate is produced. But since, according to the technology, the plates need to be screwed to the window frame, you can use any window plates (only for the sake of economy, of course).

By the way, regarding screwing the plates into the frame. There are so-called crab plates. That is, they cut or snap into the profile.

So, if there is a quarter in the opening, many installers do not screw such plates. The window will not fall out, and this is the most important thing. After all, a quarter holds the window.

It must be said that there are cases (nowadays less often) when window installers, grossly violating installation technology, do not use fasteners at all. Simply fix the window with wedges and fill it with polyurethane foam.

I hope such cases will pass you by.

3. Wood screws. Used for attaching windows to wood. The cheapest fasteners, and this is probably the only plus.

4. Screw for concrete. I think it is only used in Europe. I went to the professional store “Fixtures” in St. Petersburg, where you can buy a lot of things, and talked with the sellers. They don't have these screws.

How to attach plastic windows to brick?

Brick is good material for the construction of buildings. But attaching plastic windows to brick is sometimes problematic. What exactly is the difficulty?

If you use a frame dowel, then it is better to drill holes in the frame for this dowel not in advance, but locally.

This is necessary in order to get the anchor directly into the middle of the brick, and not into the mortar between the bricks. Of course, no one does this (by the way, neither do I). After all, this is a waste of time.

It is advisable to choose a frame dowel of the longest possible length (minimum penetration into the brick is 6 - 10 cm). If the brick is hollow, then use the 202nd anchor.

You can use anchor plates in brick if you are sure that the brick is not hollow. But even solid brick can be of poor quality. And it will be very difficult for a non-professional to attach the plate into it.

How to attach plastic windows to wood?

The ideal option for fastening windows for wood is anchor plates. And no one can convince me of this. Frame houses or timber, plates only.

From my bitter experience, I’ll tell you how I fastened windows with screws to the top of the frame in a house made of timber. And there was a casing, and a gap of about 4 cm. A year later, the timber began to shrink, and these screws, together with the timber, went straight into the double-glazed windows.

As a result, several double-glazed windows were replaced under warranty. Got the money. After this incident, if I use screws, then only in exceptional cases, and only in the side parts of the window frame.

By the way, even during construction frame houses, professionals do not recommend using hardened screws. Wood is a living material and when moved, screws break, and a nail, for example, bends. The same principle applies to the anchor plate.

Anchor plates for wooden houses are good for the following reasons:

  • Quick installation;
  • Compensates for thermal expansion;
  • They do not affect window structures during shrinkage.

How to attach plastic windows to aerated concrete?

The aerated concrete wall is loose. Can be mounted on a frame dowel with a maximum length of 202 mm. This is the easiest and fastest way.

But it is more correct to attach plastic windows to anchor plates through a special dowel for aerated concrete. It's a little longer and more complicated. In addition, you need to buy or have a hex bat in your arsenal.

How to fix plastic windows in concrete?

If you mean concrete good quality, from which, for example, lintels are made over window openings, then drilling such concrete with a diameter of 10 mm under a frame dowel is a bit difficult, but it is possible.

In this case, it is better to use anchor plates. But it is more efficient to attach panel and block houses to a frame dowel. It's more reliable and faster.

At the beginning of the article, I said that the choice of fasteners for windows also depends on the type of structure. So I want to talk about this type of glazing of loggias and balconies.

As a rule, the window fasteners fall into the very edge of the top concrete slab or into the edge of a brick bottom and side wall. Therefore, attaching loggias to the edge of the wall using a frame dowel can be quite dangerous.

Anchor plates are a great way out of the situation.

And finally, I would like to say about the big advantage of anchors, which is at the same time a disadvantage for anchor plates.

When the window frame is attached to anchors, at the time of drilling you level only one vertical plane. And you adjust the second vertical plane after inserting the anchor.

When fastening with anchor plates, you will have to set two vertical planes at once and only after that make holes with a hammer drill. This requires certain skill and skill.

Plastic window structures are rapidly ousting their wooden counterparts from the market. If you also decide to replace your old windows with more modern designs, it won’t hurt you to read the instructions for installing new PVC windows yourself. Professional installers charge quite a lot of money for such work. Does it make sense to overpay if you can solve all the problems yourself?

It is assumed that before the installation begins, you have already decided what window size will suit you, what configuration the new systems should have, what fittings you will order, etc. Solve these issues yourself or with the help of a consultant from the company you decide to entrust with the production of plastic windows.

Immediately before starting installation, you need to decide whether you will fasten the windows through the frame or use a method that involves the use of special fastening “ears”.

The first option is more common. However, it may seem inconvenient to you for the reason that before installation begins, you will need to remove the hinged sashes from the frame, and remove the double-glazed windows from the blind sashes.

The second option is more convenient for self-installation– you don’t have to disassemble anything, therefore, the risk of damage to the structure and violation of its tightness is minimized.

When choosing the second method, find yourself a smart assistant in advance. The assembled window weighs quite a lot, and installing it yourself is incredibly difficult.

Preparatory work

Just before the start PVC installation windows, you have to perform a number of important preparatory work.

Preparing the site

When ordering windows, check when they will be delivered to you. Start preparing the site shortly before the windows are delivered.

First step. Move all furniture and appliances away from the window opening.

Second step. Cover the floor and radiators protective film

or thick fabric. Third step. Organize

workplace

so that nothing bothers you, and everything you need to install the window is at hand.

First step. Remove the sashes and dismantle the double-glazed windows if you prefer the fixation method through the frame.

To remove a double-glazed window, carefully pry up the fastening bead using a simple chisel and carefully press the fastener out of the groove with the same chisel. First, remove the vertical fastening beads. Then, in the same order, remove the horizontal fasteners.

To avoid confusion in the future, be sure to label the fasteners. Their size may differ slightly, but even a difference of a fraction of a millimeter will be enough to cause gaps to appear.

Second step.

Tilt the window frame. The glass unit will come out of the mounting grooves on its own. Carefully place the removed glass unit against the wall or other stable surface at an angle.

Third step.

Remove the plugs from the sash canopies and unscrew the fastening bolts. Next, you need to release the top part of the casement window. To do this, turn the knob to “ventilate”. Reach the hook located in the lower canopy.

As a result, you will get a “bare” frame with jumpers.

Fourth step.

Prepare holes for anchors on the inside of the window frame. Place the holes around the perimeter of the product so that there are at least 3 fastening points on each side, and at least two at the bottom and top.

Second step.

File the box and frame at several points.

Third step.

Use a crowbar to pry up each part of the structure and remove the frame from the opening. In some situations, it is more convenient to immediately find the two hundred nails that hold the window in place and pull them out.

Fourth step.

Remove the thermal insulation and sealing materials that appear under the box.

Fifth step.

Remove old slopes using a hammer drill. If the slopes are in good condition, you can leave them alone. At this point, focus on your plans for the further design of the slopes.

Sixth step.

Pry up and remove the old window sill. Seventh step. Get rid of the cement backing under the window sill and at the bottom of the window opening. A hammer drill will help you with this.

Eighth step.

Collect construction waste in suitable containers and dispose of it in the trash. Take the remains of the dismantled window there.

Ninth step. Align the ends of the opening and clean them of dirt. Prime the surfaces. Tenth step. Relevant only for residents of old wooden houses. Lay waterproofing material around the perimeter of the opening. In some situations, it is necessary to additionally install a wooden reinforcing box.

If necessary, the dimensions of the opening can be reduced using

cement screed

. At this point, focus on the conditions of your specific situation.

Installing and securing a new window

Proceed with installing the pre-prepared window.

Fourth step.

Check that the window is installed vertically. Detected deviations are eliminated as in the previous step.

Fifth step.

Proceed to secure the window with anchors in accordance with the chosen fixation method.

Fastening using the “through the frame” method First step. Take a hammer drill and drill similar holes for fasteners in the wall directly through the holes prepared in advance in the frame. Second step.

Secure

bottom part

structures on both sides. To do this, you need to insert and secure the anchors, but you do not need to complete the fastening immediately.

Third step.

Make sure the window is positioned vertically. Immediately correct deviations according to the scheme already familiar to you. If everything is fine, use a hammer drill to drill holes in the central and upper parts of the window frame. Insert and tension the anchors. Information on the required number of fasteners was given earlier.

Fourth step.

Re-check that the window is installed evenly. Get rid of deviations immediately if you find them.

Fifth step.

Tighten the anchors fully. Do not overtighten them, because... the frame may become deformed from excessive tension.

Plate fastening

In this case, special plates will be used to fix the window. They are placed on one or two sides of the window block. The plates are made of thick metal and have the shape of “ears”. Such elements are initially provided with holes for anchors.

Make sure the valves move normally. In its normal state, the sash does not produce any unauthorized movements when it opens 45 degrees and 90 degrees.

Third step.

Complete the inspection and seal any existing gaps between the walls and the newly installed window. Fill the gaps with special mounting foam in cylinders.

At this point, the main work of installing PVC windows yourself is considered complete. At the end, all you have to do is install a plumb line, a window sill, a mosquito net and make slopes at your discretion.
