Creating and installing slopes on windows with your own hands: how and what to make from, what is required for this?

Self-installing window slopes has both practical and aesthetic advantages, making it a worthwhile home renovation project. Window slopes, sometimes referred to as reveals or jamb extensions, are crucial for enhancing insulation, sealing the window frame, and giving your windows a polished appearance. Whether you’re installing new slopes or replacing old ones, doing it yourself gives you the opportunity to alter the materials and design to fit the aesthetic of your house.

For longevity and aesthetic appeal, selecting the appropriate materials for your window slopes is essential. Common materials include wood, plastic, plaster, and drywall. Every material has benefits of its own, such as wood’s classic, natural appearance, plastic’s durability and ease of cleaning, plaster’s seamless finish, and drywall’s affordability. Your decision will be influenced by your space’s overall design, your skill level, and your budget.

Prior to beginning, collect all required equipment and supplies. For accurate cuts, you’ll need a miter box, a level, a saw, screws, a screwdriver, and insulation materials. To guarantee that your window frames fit your slopes snugly, take precise measurements of them. In order to minimize heat loss, think about adding foam or other insulating materials. Proper insulation is essential for energy efficiency.

Window slope installation and creation can be a simple do-it-yourself project that improves the comfort and aesthetics of your house, provided you have the proper supplies and preparation. It’s an opportunity to hone your abilities and give your home a unique flair. Years of professional-looking results can be yours with patience and adherence to a few basic steps.

How to install correctly: requirements and GOSTs

Window slopes may seem simple on the outside, but they need to be designed to comply with GOST No. 26602.1, 26602.2, and 26602.3, published in 1999, in terms of heat and sound protection, allowable installation seam dimensions, and sealing conditions.

Essential conditions for putting these structures in place:

• they must be warm and soundproof;
• should not allow wet vapors to escape from the room, the standard vapor permeability is set at a level not lower than 0.15 mg/(m*h*Pa);
• they should not have cold bridges;
• It is recommended to install at an internal temperature of at least 15 C;
• be resistant to long-term weather conditions;
• have adhesive strength;
• be deformation-resistant;
• have a good appearance that matches the window design and the overall design of the room;
• have a long service life;
• be able to compensate for the thermal expansion of PVC windows;
• insulation of slopes must correspond to the design of the external wall and the installation location of the window unit.

Note: In order to prevent the possibility of local freezing of the outer wall in the area where the window is installed, regulatory requirements regarding energy saving of buildings must be met when protecting slopes against heat, moisture, and noise.

Necessary materials and components

In order to maintain the window structure’s protective qualities against heat loss, moisture, and street noise, the materials used to create the slopes must meet certain requirements. They also need to match the way the building’s exterior and interior are designed.

Slope installation on Euro-windows is most commonly done as follows:

1. Plastic lining, the most budget option with easy installation, with a large selection of exterior finishes. Special fittings are installed on the edges of the structure, which cover the areas where the frame adjoins the wall. Several layers of protection against heat loss, moisture and street noise must be laid under the lining.
2. PVC sandwich panels, made of foamed polystyrene, protected on top by a polymer shell. More prepared for self-assembly, have fewer fittings and a modern appearance. Among the disadvantages, they have a higher cost, they burn with the release of toxic substances, and have low protective characteristics in terms of heat and sound.
3. Plaster – a very reliable, proven option for finishing slopes. Is a good base for improved puttying and painting. In the retail chain you can purchase putty with decorative qualities, for example with particles of natural marble. Such a slope can serve properly for a very long time, it is fireproof and environmentally friendly. The disadvantages of plastering slopes include the high cost and the requirement for the contractor to have special skills.
4. Drywall – a popular building material, most often used for installing slopes. It has high strength characteristics, is not afraid of moisture and has a long service life. It retains its shape during temperature changes and does not emit toxic substances, the material is fireproof, and no professional skills are required to work with it. Drywall is used as a base for finishing. The disadvantages include high labor intensity; after installation, the application of putty and primer layers is required.
5. Wooden prefabricated panels belong to expensive elite slopes. They can be put in special cases – when it is required to emphasize the features of the interior. Since natural wood is subject to constant deformations, DVP or DSP slabs covered with veneer are used as panels. Such designs are easily installed, durable, warm and have high protection from street noise. The disadvantages include high cost, moisture and fire.

Is sheathing using sandwich panels possible? The choice for these slopes is as follows:

You will need fasteners, sealant, glue, and foam in addition to finishing material to create slopes out of plastic, plasterboard, wood, and plaster.

Mounting choices:

• Drywall and gypsum fiber board (gypsum fiber) – with gypsum mounting adhesive.
• Plastic panels and PVC lining – “liquid nails” glue, the second option is on slats with fastening with self-tapping screws. The void between the panel and the wall can be treated with polyurethane foam. It is allowed to use a combined fastening method: self-tapping screws + foam.
• Plastic panels are secured to drywall with a construction stapler.

Sealant

Both interior and exterior work can use the sealant, depending on where the slopes are produced. Sealants used in outdoor installations are subject to particular requirements because they need to be able to withstand harsh environments.

Conditions for sealants used externally:

• High chemical resistance characteristics. Resists mold, water and chemical penetration.
• High resistance to mechanical stress.
• High elasticity.
• High thermal protection characteristics.
• Have an easily paintable structure.
• Have good fluidity to fill all hard-to-reach areas when applied.
• High adhesion, strong bonding to the surface.
• Wide operating temperature range.

For interior work, the primary needs for sealants are moisture resistance, resistance to biological damage, lack of toxins, and environmental safety.

Popular and dependable sealant types include:

Glue

In addition to serving as a protective element, it is employed to fasten a corner to a slope.

It strengthens the corners on slopes against mechanical damage by sealing the joints.

In the retail chain, there are several dozen different types of glue. When selecting, it’s crucial to consider the corner’s material and the surface it will be glued to, as well as the amount of work involved, the environment, and the surface’s preparedness for processing.

The top three dependable brands of glue for creating window slopes are:

1. "Moment Installation MV-70» – belongs to the “liquid nails” group, allowed for use in external and internal environments. Works with many building materials without nails, screws or dowels: wood, ceramics, plaster, cork, metal and PVC. Advantages:
2. high initial adhesion force – 70 kg/m2;
3. high temperature range for operation from -20 to +80 °C;
4. high moisture resistance;
5. no pungent odor;
6. fixes hard corners on curved surfaces well.

• a special gun is required for work;
• white color;
• fast setting, therefore it is necessary to remove excess immediately.

A 400 g tube costs 220 rubles.

Cosmofen PLUS HV — belongs to the “liquid plastic” group, suitable for working with plastic, PVC, wood, vinyl and aluminum. Scope: it can be used to glue slopes, louvered strips and ebbs. Advantages:

• setting in 5 minutes;
• transparent;
• moisture-resistant;
• no pungent odor.

Lower strength characteristics compared to the Moment Montazh MV-70 are a drawback.

Foam

While it can’t be strictly categorized as an adhesive group, polyurethane foam is a polyurethane foam sealant and not precisely an insulator.

Foam is used extensively during window installation, particularly to fill the mounting gap between the frame and the wall opening.

When installing window slopes, it is important to consider the significant volume increase that occurs when applying polyurethane foam as it hardens.

Professional or domestic foam can be used for slopes. Because it doesn’t require exact material dosing, household foam with an adapter tube is better suited for smaller jobs. Expert foam beneath the "gun" is applied with extreme precision, yielding the best sealing outcome.

Advantages of household foam

• small expansion coefficient;
• convenient packaging for small amounts of work up to 300 ml;
• high coefficient of secondary expansion up to 2 times;
• low cost;
• economical packaging;
• low shrinkage percentage, about 5-7%.

Crucial! When using household foam, take care to fill the space between the wall and the slope with no more than 1/3 of the volume to avoid changing the slope’s geometry.

One drawback of household foam is that it only releases part of the aerosol; the remainder stays in the container.

Professional foam’s advantages

• large cylinder volume 750 ml or more;
• practically does not expand when filled;
• does not affect slope deformation;
• low shrinkage up to 0.3%;
• high adhesion to various building materials.

Cons: Expensive; the gun needs to be thoroughly cleaned with a special solution after every foaming stage.

It’s important to follow the recommended temperature range when handling foam.

If not, it will have an impact on the foamed joint’s density, hardening time, and performance. Before buying the foam, it is necessary to understand this parameter, which is stated on the packaging:

• summer – from +5 to +35 C;
• winter from -10 to -35 C;
• all-season from -10 to +35 C.

The most widely used polyurethane foam brands for caulking window slopes are:

1. KUDO, all-season, 1000 ml, price 530 rub. Advantages:
2. high adhesion;
3. works with all building materials;
4. ideal finely porous structure of the finished layer;
5. stable output;
6. affordable price;
7. adapter tube.

The 24-hour drying time is a drawback.

Makroflex WhiteTeq PRO, new polyurethane foam composition, universal, summer, 750 ml, price – 412 rub. Advantages:

highest foaming efficiency;

crystal white foam;

high drying speed 0.75 hours;

possibility of coloring;

wide range of operating temperatures from -40 to +80 C;

high level of sound absorption;

average price.

• presence of a pistol in the kit;
• high quality seam;
• wide range of applications;
• budget cost.

Here is a more detailed discussion of selecting polyurethane foam for windows.

Fasteners

Self-tapping screws can be used to fasten the slope panel to the aperture. The most popular choice is the first one. A rod with a head and an externally sharp triangular thread is called a self-tapping screw. It simultaneously cuts a thread when it is tightened.

Since they provide a more dependable connection for a variety of building materials, they have nearly entirely replaced traditional nails in use today. They are safe because there is minimal chance of harm occurring while they are at work.

Primary self-tapping screw types categorized by material:

1. Carbon steel has high strength, but is susceptible to corrosion processes.
2. Stainless steel with 10 content.5% chromium, creates very strong and rustproof connections with unlimited service life.
3. Brass is an alloy of copper with zinc, in some cases with tin, nickel, lead, manganese and iron. Very durable and wear-resistant.

Coating self-tapping screws is possible:

• phosphating method (black) for rooms with high humidity;
• oxidized from carbon steel with a black oxide film, for rooms with average humidity;
• galvanized self-tapping screws for interior and exterior work;
• uncoated, only for interior work in rooms with normal humidity.

Self-tapping screw types according to application:

1. Universal galvanized, with a countersunk head, a cross-shaped slot and a sharp tip – for indoor and outdoor use, materials: wood, plywood, chipboard, plasterboard and metal with pre-drilling, D = 3-6 mm, length from 12 to 200 mm.
2. On wood – black and yellow self-tapping screws with a countersunk or semicircular head with a cross-shaped slot, a rare thread pitch and a sharp tip.
3. On plasterboard on metal profiles – with a frequent step and a drill at the end, wood screws are suitable for wooden sheathing.
4. For metal profiles – with a sharp tip and a head in the form of a press washer with anti-corrosion characteristics, which increases the contact area and ensures a tighter pressing of the elements against each other.
5. On concrete – galvanized self-tapping screw made of galvanized steel with a sharp end and a cross-shaped or six-pointed slot with D over 7.5 mm and length 50-200 mm.

Suggestions. The base of the concrete surface should be considered when selecting a self-tapping screw. If the base is loose, pre-drilling is not necessary, and if it is hard, a deep hole can be made.

Corners

Slope corner types are typically utilized in conjunction with rigid structures. A flexible profile is present if the slopes have an arched shape. The rigid structure has a length of 2.6 to 3.0 meters and shelf sizes ranging from 10 to 100 mm. It is constructed in the traditional rectangular profile. Any color can be used for the glossy or matte front surface.

Benefits of taking hard turns:

• high-quality coating of corner junctions from different materials;
• evens out unevenness on slopes;
• creates an exact angle of 90°;
• wide range of applications for interior and exterior work;
• high service life of more than 20-25 years;
• easy to process and install;
• wide range of colors;
• fixed with most types of glue;
• affordable consumer price from 5 rubles. for 1 p.m.;
• does not require additional decorative processing.

The drawbacks of taking hard corners

• not high mechanical strength;
• when cutting, it may crack in the cut area;
• the surface may be damaged during operation;
• loss of color during use, for example, white becomes yellow;
• flammable, releasing harmful gases.

A longitudinal recess in the middle of the structure, which permits the corner to bend to a specific angle, is responsible for the soft profile.

Soft corners’ advantages

• universality in the shape of slopes with angles from 85 to 180 degrees;
• for external and internal work;
• wide color palette;
• sold in coils of 50 m;
• shelf size from 10 to 100 mm;
• leveling the curvature of the slope surface;
• low percentage of waste during operation;
• convenient transportation and storage;
• affordable price from 15 rubles. for 1 p.m.;
• easy processing with any cutting tool.

The drawbacks of rounded corners

• Low quality products may not hold the curved shape of the slope well;
• flammable material.

Required Tools

Depending on the option chosen, a set of slope-making tools is chosen.

For a do-it-yourself craftsman, installing plastic or sandwich panel slopes is the most cost-effective option.

The following equipment and materials will be necessary for this task during the working process:

• material for slopes with a margin of 10-15%;
• starting U-shaped or F-shaped profile for designing an external corner;
• protective corner;
• self-tapping screws for fastening the profile;
• wooden/plywood slats – 100 mm;
• glue;
• stapler with staples;
• polyurethane foam;
• screwdrivers;
• mounting gun;
• screwdriver;
• building level;
• sealant.

Regarding plaster finishes:

• construction mixture;
• drill;
• hammer;
• dowels and screws;
• construction level;
• spatula for applying and leveling solutions;
• trowel for a solution of solution;
• plastering kelma;
• mixer nozzles for the preparation of the solution;
• Glad and grater;
• primers;
• wide brushes and a roller with a bath;
• templates for aligning internal and external angles;
• a square, roulette and level;
• mounting syringe;
• sealants;
• protective gloves;
• Handing and performer for the preparation of slopes.

Instructions describing the stages of work step by step

They first gather a set of equipment and supplies before starting to prep surfaces for the installation of slopes.

This procedure is dependent on the state of the walls; if there is sufficient room to install insulation on the slopes, it frequently just involves removing the previous coating from these surfaces.

1. Treated slopes must be primed with an antiseptic primer in 2 layers to destroy mold and other biological contaminants.
2. If you need to remove part of the plaster to install the heat-protective layer, you will need a hammer drill with a specialized chisel-shovel attachment.
3. It is necessary to remove dust from cleared slopes with a soft brush or wide brush, after which they are primed with an antifungal solution.
4. Next, cut out and install false slopes and begin foaming the space.

How to foam?

The simplest method for foaming with a household foam bottle for do-it-yourself craftsmen. It is ready for use after a tube attachment is screwed onto it.

It’s a little trickier to use highly professional foam; you have to screw the gun onto the cylinder, and then the foam will flow into the barrel through the outlet valve until the user pulls the trigger.

Professionals’ tips for handling polyurethane foam:

1. It is recommended for use for gaps over 10 mm, if less work is done with glue or sealant.
2. For gaps larger than 100 mm, additional filler will be required, such as thermal insulation or bars.
3. For better adhesion, the surface is moistened before applying foam, and after obtaining a seam, it is moistened with a spray bottle.
4. Do not foam oily surfaces.
5. When applying foam, you need to take into account the expansion coefficient and observe the ambient temperature conditions.
6. Before use, shake the can for 60 seconds.
7. Until the foam has completely hardened, you should not touch it so as not to destroy its structure, thereby contributing to incomplete hardening.

How and what to seal after installation?

After windows are installed and seams are sealed, it is crucial to insulate the slopes. One way to do this is to install 15 mm polystyrene foam sheets on a surface that has been primed and leveled.

Polyurethane foam is applied directly to the foam, to which the insulation is fastened.

Pressed firmly against the slopes is the part covered in glue strips. to the top, and then to the side walls. The spaces between the foam plastic joints can be filled with more foam if needed.

Note: Special fasteners called "fungi" are required to attach the insulation to the wall if the slopes are wide.

Alignment

Plastering is the most dependable method for leveling the slopes on which a new window installation requires leveling. You’ll need the following supplies to complete this:

• Putty-plaster mixture.
• Dry building mixture for puttying and plastering work.
• Finishing putty.
• Putty for finishing slopes.
• Primer antifungal composition.
• Perforated masking profile for strengthening external corners.
• Perforated profile makes it easier to remove corners
• Finishing decorative material – according to the preference of the owners.

They start by aligning the polystyrene and then reinforce it using a fiberglass grid. Applying glue to the slope’s corner with a spatula, pressing the corner onto it, and removing any extra glue right away are the next steps.

Apply putty or glue to the corner on the outside in a similar manner. And use a gypsum composition if a rapid drying of the surface is required.

Using a spatula, press the mesh into the applied composition; remove any excess. This layer serves as a preparatory layer for the finishing putty, which needs to be applied to the surface once it has dried.

Using a wide spatula and light pressure, apply the final finishing layer, which is 1-1.5 mm thick, moving from the frame into the room. Finishing the smoothing process with grout involves counterclockwise circular motions. To ensure an even paint layer, prime with a second coat of primer before finishing the painting.

Finishing

By using false slopes, you can complete the slopes more quickly. PVC panels come in two varieties: sandwich panels with a heat-insulating layer and regular PVC panels.

In this situation, the contractor needs to plan ahead for installation techniques such as using glue or a fitting profile, choose building materials, and determine whether extra insulation needs to be installed during the installation process.

When and for what structures is it required??

For all varieties of window structures, slope finishing is required. The installation technology is chosen based on the slope’s technical characteristics and the contractor’s construction-related experience. Finishing is applied to the plastic slopes inside the window opening around their perimeter. Installing fitting profiles on it and strengthening the corner with wooden slats will accomplish this.

Be aware that an extra wooden beam is fixed between the frames if the window opening is larger than the ones being installed. Typically, it is put in place when foaming the spaces created by the window and the wall during installation. Next, the first beam’s cross section must be taken into consideration when choosing the rail thickness that is fixed along the outer edge.

Next, choose the location for the initial profile to be laid. When installing a wooden beam, the profile is pressed against the frame and secured to the beam using a stapler. If the beam was not installed, the profile is fastened along the frame’s upper and side edges, with special attention paid to the outer rail. On the walls and ceiling, a corner profile is installed with two gaps for the installation of PVC panels.

What materials are produced?

PVC Flocals are fixed using the F-shaped profile, which serves as both the platband and the finishing panel holder.

It is fastened to a wooden rake that is positioned outside the slopes.

The F-profile is connected at a 90-degree angle and cut at a 45-degree angle at the corners. A knock is used to get the ideal cut.

Subsequently, parts of the required size are cut out of the completed panels using the slopes’ dimensions. The completed components are then placed into the profile grooves. They can be somewhat reversed in certain circumstances.

Occasionally, gaps appear where the profile’s edges do not entirely fit into the workspace following such a bend. Apply silicone sealant where necessary to restore them to their original position, and then use masking tape to temporarily secure the assembly by gluing it to the finishing panel’s surface.

Sealing joints

Plaster windows do not require seam sealing, but PVC windows with plastic structures do. If a gap has developed while the window is in use, it is most likely the result of errors in the Euro windows’ installation technique. It will take jointing, removing the old foam, and foaming new foam to seal such a gap. It is best to do this work during the warmer months.

How?

There are many different types of sealants available on the market; to choose one professionally, you must consider the installation seam’s depth and width, the slope’s material, the connection method to the frame, and the temperature and humidity of the surrounding air.

Slope sealants come in two varieties: one component that can be applied right away and requires no mixing, and multicomponent sealants that must be mixed beforehand.

They can also be non-drying, which can soften when heated and dry under operating conditions to an elastic state, and vulcanizing, which takes on an elastic rubber-like state when exposed to heat and moisture.

Guide to Repairing Gaps

Using acrylic sealant as an example, the primary steps involved in removing gaps between slopes and the frame are as follows:

1. Seal the treatment boundaries with sealant approximately 2-3 mm from the gap with masking tape.
2. Fill the gap between the slope and the frame with acrylic sealant.
3. Take a glass of water and a brush dipped in water, level the sealant until the required level of surface treatment is obtained.
4. After complete drying, the gap is painted in the desired color.
5. After the paint layer has dried, remove the masking tape.
