When windows are replaced, everyone strive to repair so that not only the window, but the whole system stood as long as possible. I also want to achieve maximum thermal insulation, so that the design was unpretentious in care, and also looked aesthetic and fit into any interior.
Sandwich panels
Variations of decoration of slopes
Self installation sandwich panels
As practice shows, the most problems occur in the purchase of building materials for the design of slopes. If the house was built on Canadian technology, the slopes are much simpler: in the sip panel, in which the opening of the window is scheduled for the window, the triangle of the desired size is cut out, the heat insulation of which the panel itself provides. If the opening for the window is large enough, blocks from the sip panels over the window and under it, after which the window itself is installed. In this case, thermal insulation is maintained in the same quantity.
It happens that drywall is used to create slope for windows, but the probability of freezing of such a finish in winter cold appears, and it is much more difficult to care for such a slope.
If the building is built of brick or reinforced concrete blocks, only a sandwich panel will help maximum heat insulation. As the masters advise, it is also possible to use cellular plastic, but its density and impact strength is too small, and the installation works are too time-consuming.
How are the sandwich panels arranged?
Using sandwich panels for windows
The sandwin panel is a stove of 3 layers of material, in two external tiers of which is the hard plastic. The space between them is filled with foam or polystyrene. On the market you can see the more affordable material. At the same time, polychlorvinyl is placed on polystyrene, but there are already difficult to call such panels with a sandwich. Also, this analog is not distinguished by durability, so it is better to abandon such material from the design of windows.

On the quality of the decoration of slopes has a direct impact and the method obtained polystyrene. If you are using extruded polystyrene, note that its mechanical features must be greater than the free-foamed polystyrene.
The most popular block dimensions for window design are shown in the table.
| Sheet thickness | Total panel density | Block size | |
| length | width | ||
| 1mm. | from 10 to 40mm | 1300-2000mm | 3000mm |
| 1,4mm | 800-1500mm | 2000-3000mm | |
| 2mm. | 1300-2500mm | 3000mm |
Please note that 4 cm sandwich panel is made only to order.
The sandwich panel has the following specifications:
| Feature | Indicator |
| Noise insulation level | Not less than 21 db |
| Density of material | 30-35kg / m3 |
| Compressive strength | Not less than 0.25 mp |
| Thermal conductivity | Not less than 0.028 W / m |
Advantages and disadvantages of finishing
Installation Sandwich panels
Sandwich blocks have such positive qualities as:
- Do not need subsequent decoration (their texture is similar to the coating of plastic windows and windowsides), you can additionally illuminate;
- not covered by cracks and are not amenable to moisture;
- allow you to achieve maximum insulation, because the Sandwich block does not miss cold air flows;
- Not whimsical care, from their surface without much difficulty, you can remove even solar pollution;
- Prostate installation (not exceed only plastic slopes);
- May be in operation until 20 years.
Following such positive qualities, the sandwich can be called the most suitable material for finishing plastic windows.
Cons of such panels are due only to their low quality, namely:
- yellow and deform from high temperature and sunlight;
- have low strength;
- As a result of the installation, beats and holes may form due to the unevenness of the canvas sandwich (although the experimental finishers will cope with this problem).
As you can see, there are no terrible flaws from panels, so it is safe to say that this is the perfect material for the construction of slopes.

I would like to note that externally, the material is not very attractive, but it is possible to solve this problem if you buy a laminated product, however, its value is an order of magnitude higher.
Installation of panels
Preparation of windows under the decoration of the sandwich panels
Registration of windows with such a finishing material has specific and technical features, if not to consider which will be problematic to achieve excellent results:
- If you live in a hot climatic zone, use a renolite coating panels, because such a film is not afraid of heating to 70 ° C, unlike plastic, which will immediately be deformed;
- During the installation, pay attention to the level of the linear expansion coefficient;
- For cutting material, it is best to use a disc feeding plate with a small step of teeth, otherwise plastic risks cracking or stratify;
- It is not necessary to cut the material at low temperatures (less than 5 ° C), because the panel can become especially fragile from the cold;
- By installing the panels, use this starting profile that recommended the manufacturer, to allow its replacement to something else is categorically prohibited;
- After the installation is complete, do not forget to remove the protective film.
As you can see, the installation of the panels is much easier and faster than the design of windows by plasterboard.
Operational features
Sandwich panels
Despite the ease and rich color gamut, the panels for windows are classified:
- in terms of resistance to ultraviolet;
- By the degree of moisture absorption;
- By resistance to the effects of abrasive external substances;
- by level of resistance to cyclic loads;
- Operating temperature range.
How to make slopes with your own hands?
Sandwich panels for windows
The process of installing slopes for windows must be performed in the following sequence:
- To begin with, the ends of the window from the mounting foam are clearing, to ensure accessibility to the end grooves of profiles.
- Install the starting profile.
- Next, additional sealing of the canvases is carried out, which also serves to fix starting coating.
- Now you can mount the panels, cutting them into the blocks of the desired size.
- Then the blocks are attached to the window to the window with the help of a mounting foam.
- At the next stage, the platbands are mounted, which are glued to the walls with liquid nails.
- At the end, the joints are sealing, which were formed as a result of contacting the slope and the windowsill. To do this, it is better to purchase white silicone.
