Window decoration in a wooden house, slopes and window sills: outside and inside, wood and plastic, external and internal cladding

The slope is the part of the window opening that frames the window around the perimeter. After installing the window, this part needs to be processed to give the entire structure a finished look.

Those who are faced with renovating or building a house for the first time do not always understand why slopes on windows are needed. And really, why? After all, the frame is already in the opening, the doors open and close, so why spend extra money on framing? But after a while, even the most inveterate skeptics will admit that this window trim detail performs very important aesthetic and practical functions.

Note that it is advisable to install slopes immediately when installing windows. But if this is not possible, you can do it after some time.

The need to finish slopes from the outside

External finishing of plastic windows in a wooden house performs the following functions:

aesthetic. Slopes hide installation flaws and defects. You can admire the finished slopes for a long time. They give the house a finished, impressive look;
protective. They protect the frame, opening and insulation from precipitation, wind and sunlight;
thermal insulation. Slopes will reduce heat losses and create a barrier to the penetration of cold;
soundproof. They prevent the passage of extraneous street noise.

Insulation

An important part of the repair work associated with the installation of slopes is the insulation of the window frame. Of course, you can do without this, but in winter it will be much colder in an uninsulated room. The following are considered as insulation:

Styrofoam;
penoplex;
mineral wool.

Styrofoam

Budget insulation, which is in great demand among consumers. It is easy to work with, it costs a penny, and in terms of thermal insulation it is not much different from other competitors.

Penoplex

An expensive analogue of polystyrene foam, which differs from its “younger brother” in energy-saving properties. Among other advantages of the material, the following are noted:

more dense structure;
less tendency to absorb moisture.

Mineral wool

It is used in the case of insulation of frame structures, as it is extremely convenient to install. When purchasing material for insulation, pay attention to moisture resistance. Brands that tend to absorb excess liquid are not suitable for insulation.

How to choose the right finishing element

To choose the right finish, it is important that it meets the following criteria:

matched the style of the window and the interior of the house;
was durable and moisture resistant;
served for a long time, at least the window service life: 15-20 years;
It was installed easily and simply so that any beginner could cope with its installation.

Classification of slopes

Slopes are classified by size, material of manufacture, shape, location.

Based on material they are divided into:

metal, powder coated. Suitable for finishing exterior windows on facades covered with metal cladding or vinyl siding.
plasterboard. This is an excellent option for leveling slopes. But plasterboard does not withstand exposure to precipitation, so it is used for interior cladding. In order for drywall to withstand weather conditions, frost and heat, it is important that it be moisture resistant. It is not the final covering. Ceramic tiles or painting can be used as cladding;
plastic. Plastic is the best finishing for slopes. It meets all the criteria for choosing cladding: practicality, low price, high installation speed, attractive appearance. Sandwich panels are considered one of its varieties. In them, the outer and inner panels are connected by insulation: foamed polyurethane foam;
MDF. The material is highly resistant to mechanical stress, is inexpensive, but can absorb moisture. Therefore, it is not suitable for external slopes;
wooden. To improve the quality of wood and extend its useful life, it is treated with antiseptic agents before installation. Coating with several layers of varnish will help protect the wood from external influences.

When the window is placed as far outward as possible, the frames in the house are made of profiled timber

By size

Depending on the size, slopes can be narrow or wide. The latter have a width of more than 200 mm. They are installed in log houses. The width of narrow ones varies from 50 to 200 mm. The choice of type of slope depends on the size of the window and its location relative to the central axis of the facade.

If the window is small, then narrow slopes visually reduce its dimensions. If the window block is pressed inward, but not deeply, then a wide slope is installed.

For a window flush with the wall, a narrow slope is used.

Internal slope made of furniture board - 18 mm thick pine

By location

Internal slopes give the room a beautiful look and protect from drafts. They are made from any materials.

In order for external slopes to be durable and protect windows from environmental influences, it is important that they are strong and wear-resistant. They are made of plastic, wooden lining or planed boards.

By shape

The shape of slopes can be straight or oblique. Direct ones are mounted to windows with standard double-glazed windows. Oblique ones are necessary for roof windows. They protect glass from freezing and condensation.

What types of wood are suitable?

It is not enough to simply choose a wooden slope in a store and install it on a plastic window; you also need to know what type of wood such products are most preferable from. It is recommended to consider the main breeds that are used today:

Larch. It has a beautiful red-brown tint and good performance indicators.
Does not require the use of antiseptics, durable and fire-resistant. Resistant to moisture and frost, tolerates temperature fluctuations well.
The downside is that it is not thermally conductive, takes a long time to heat up, and may crack over time.
Oak. This is a durable material that exhibits unique hardness characteristics.
Oak can withstand high loads. It is dense and dry, so it is well suited for finishing. Oak is resistant to moisture and biological influences. Insects do not like it and fungus rarely forms on it. The downside is the high cost of the material.
Pine. Easy to process, resistant to moisture and environmentally friendly.
This material is the most affordable and has many color options. The disadvantages include the possible release of resin and the appearance of dark spots during prolonged use.
Linden. It is easy to process, has a low cost, but requires careful drying and is not a dense material.

From the point of view of installation outside the window, it is important to choose those species that are resistant to bad weather and different temperatures. Larch and oak are suitable, pine will also be relevant, but if not properly processed over time, this species may become covered with dark spots. For indoor installation, both linden and oak, pine and larch are suitable.

Features of PVC and wood material

Slopes in a wooden house are often made of wood and plastic. Let's consider their features.

Plastic is a synthetic polymer without taste or smell. The density of PVC is 1.34 g/cm3. It has low heat resistance and high dielectric properties.

The advantages of plastic include:

strength and reliability;
moisture resistance, the ability to protect windows from destruction and pathogenic microorganisms
does not fade in the sun;
its cost is low, which saves the budget;
it is not affected by chemicals: acids, alkalis and alcohol. Therefore, any detergents are suitable for cleaning. Simple cleaning with soap and water helps keep the panels clean;
the material is environmentally friendly, does not emit toxic substances, and is hypoallergenic;
has frost resistance, can withstand low temperatures, does not crack from cold;
a variety of designs will allow you to choose the finish to your liking;
has a long service life. It is estimated at more than a dozen years.

Plastic slopes when finishing the interior with MDF panels

The disadvantage of PVC is the inability to replace individual parts. The plastic is dismantled if the appearance is completely lost.

The advantages of wood are:

naturalness and environmental friendliness;
high breathability. Wood breathes, improving a healthy microclimate in the home;
easy replacement of individual elements;
aesthetic appearance;
strength and resistance to physical influences, durability.

Economical solution - slopes made from the remains of imitation timber

The disadvantage of wood is the high price, especially of valuable tree species.

Step by step instructions

The stages of work depend on the material of the slopes. The installation of slopes made of wood and plastic differs from each other. We will talk about how to properly install plastic slopes and wood trim.

Sandwich finish

Technology for installing plastic slopes

Plastic slopes are installed in stages.

First, the starting bar is mounted. It is attached around the perimeter of the opening.
Slopes are inserted into its grooves. They are fixed with self-tapping screws.
Decorative corners are glued with silicone.
The window sill is matched to the color of the slopes. It is attached to the horizontal strip of the opening using sealant. Self-tapping screws are not used.

Wooden slopes

Wooden slopes are secured with nails with small heads or self-tapping screws. The screw heads are puttied. The surface of the wood is stained and varnished. The planes of the opening are carefully leveled.

You can use lining for finishing. Internal slopes made of wood will be in perfect harmony with the cladding of the façade of the house using wood materials.

A plastic starting strip is mounted to the frame.
Lay the lining horizontally from the window sill upward, connecting with a tongue-and-groove lock. The width of the lining should be equal to the width of the window slope. Its edge is inserted into the starting bar.
The second edge is attached to the wall with self-tapping screws.
Trim the corners. Decorative corners are glued to the wall and part of the slopes.

Brushing furniture board

To give the lumber an unusual look, you can use brushing technology, which allows you to artificially age the wooden surface. This procedure can be carried out at home using a special torch and a stiff brush for processing metal products. It consists of the following actions:

1. The surface is treated under a small burner flame. During this process, the small fibers of the wood are burned. This makes it possible to obtain an expressive texture.

2. The next step is to brush out the unusable wood fibers.

You can also use a drill or grinder with a metal brush to artificially age the furniture board, which is later changed to an abrasive one. The last stage of brushing is treating the surfaces of the lumber with stain.

Fastening slopes to polyurethane foam

The installation procedure is as follows:

measure the dimensions of the slope;
cut out the sandwich panel in accordance with these dimensions with a margin of 0.5 cm;
excess foam is cut off after installing the window unit;
Make a furrow 0.5 cm deep along the window in the foam;
try on the panel, insert it into the groove, align the edges;
remove the sandwich panel, and apply polyurethane foam to the wall, having previously moistened it with water;
apply foam from bottom to top, departing from the corner 1 cm. You do not need to foam the entire surface, but only part of it: along the edges and in the middle. The fact is that the foam expands, taking up free space. If you do not leave room for its expansion, the foam will squeeze out the slope;
moisten the foam with water from a spray bottle and lay the panel on it; attaching to the wall with masking tape;
other slopes are mounted in the same way;
The cracks are filled with sealant.

Preparation

During the preparation process, it is necessary to focus on the defects of the installed window, if any. Their presence is checked using a building level and plumb line, as well as visually. You need to make slopes taking these into account, because if you make them even and regular, the overall asymmetry will be noticeable even more. Finishing the slopes of wooden windows inside can partly hide unevenness, but in this case you need to select individual design solutions.

To check the compliance of the window indicators, you need to take measurements of all parts. The vertical ones must match, the horizontal ones, respectively, too. If this rule is followed, you can begin preparing identical slopes.

If we are talking about arranging a window that will have blinds or massive curtains, then minor deviations are quite acceptable.

As part of the preparatory work, do not forget to check for cracks, damage and other defects on the surface of the window structure. If they are installed, they must be filled with acrylic, otherwise the installation of slopes will only add to the load on the deformations, the window may warp and, in general, it will not last long.

You should carefully remove any paint or putty from the wall that turns out to be unnecessary in the installation area. A wooden slope for a window inside will look good on a pre-leveled surface. If a lot of foam was applied when installing the window, it will appear on the outside. The excess is cut off with a knife (not cut, but cut along the contour line).

The anchor plates also need to be removed. All fasteners will be new. If there are through holes and connectors that served to fasten the old structure, they are filled with foam.

If the house is old

When repairing an old wooden house, the window sill is part of the window opening, therefore, if it is not deformed or rotten, then there is no need to dismantle it. A new plastic window sill is placed on the old one. The length of the window sill and the angle of rotation are measured. Dimensions are marked on plastic. Cut out the part with a jigsaw. The workpiece is mounted on silicone or polyurethane foam. They place the load.

A day later the slopes are installed. The starting profile is screwed into the frame. Remove excess foam from the window opening. PVC slopes are placed on the foam and the panels are secured with masking tape. The final profile is glued along their perimeter.

Inga KapustinaGus-Khrustalny / 05/12/2016

We were looking for access to a wholesale manufacturer of furniture panels. We needed boards of a fairly large size, and the criteria were: quality, scale and regularity of deliveries. Fortunately, we found all this at the TsPI company. We have been cooperating with them mutually for almost a year now. I like the quality of production in furniture panels from TsPI. They have an unsurpassed level of processing of each lamella and the shield as a whole.

Suslov GarikIzhevsk / 09/05/2015

Hello, I would like to express my gratitude to the TsPI company. We purchased a batch of linden furniture panels for our store. They broke up instantly! This is all thanks to the design of the panels - specialists select each lamella based on the design - and the excellent processing of the furniture panel. Ideal edges and surfaces of furniture make it very beautiful and attractive. People like it, and that's the most important thing.

Pugachev AntonZelenodolsk / 06/17/2015

In the linden furniture board we found exactly what we had been looking for for a very, very long time. This is the pliability of the material for cutting wood. There is nothing better than linden in this matter. Finding a manufacturer of a linden shield now is something unrealistic. Although the Internet is full of companies who supposedly sell them, in reality it turns out that “they are not and will not be in stock,” but the Center has everything. And they make them according to our sizes and standards. Just as the doctor ordered.

Frequent mistakes and problems when finishing window slopes

Window slopes in a wooden house, if done incorrectly, lead to a number of problems during operation. Let's look at installation errors and problems associated with them:

installation of slopes under profiles, and not on them, leads to blowing;
incorrectly selected linings under the window sill violate the level of the structure;
displacement of the window sill can cause its deformation;
early removal of cargo from the window sill will reduce its service life;
For external cladding, materials that are intended for interior use are used. They are destroyed under the influence of external influences;
Do not seal the cracks under the window sill. Such an error can lead to moisture getting under the tide;
cutting out the polyurethane foam completely from the window opening violates the tightness of the structure.

Requirements

There are some requirements that should be taken into account when independently selecting and installing products:

the installed materials should improve the performance characteristics of the window;
the slope must withstand mechanical stress;
the service life of the product should not be less than the service life of the window itself;
the decoration must correspond to the general style of the room;
wooden slopes must be well secured with self-tapping screws or adhesives or sealants that are designed specifically for this purpose;
The temperature and humidity conditions in the room where the slope will be installed must be observed;
joints should not have gaps, corners should be installed at transitions.

Important! Parts for outdoor installation should not be made of material that is not resistant to moisture. During the winter and fall, the product will be exposed to snow and rain, so it must withstand harsh weather conditions.
