Even on dirty seals, it is not recommended to use organic or synthetic solvents. It is better to wash with warm water with neutral household detergents, dry well and lubricate. Of course, silicone oil and glycerin are not a panacea, but they can extend the life of seals by several years.
PVC profile filled with polystyrene What affects the width of the profile The correct choice of plastic windows should be based on a comprehensive analysis of their parameters. One of the main ones is the width of the profile, in a professional language - the mounting depth. For standard windows, it is 50 - 80 mm. If the width of the frame barely reaches 60 mm, then there are no more than three cameras in it, and with a depth of up to 70 mm there are four or even 5.
Availability of certificates For each component of the window (profile, double-glazed window, fittings, components) there is a separate GOST. Manufacturers of materials and products for completing windows must obtain certificates of conformity for their products.
The ability of the window to withstand operational loads depends on the quality of the profile: opening and closing of the sashes; the weight of the double-glazed window; wind; precipitation; high and low temperatures; exposure to ultraviolet.
Wooden frames, as an alternative, also cannot be called an example of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.
Poor-quality elements can also provoke other problems with the operation of a double-glazed window. Sealant Sealant is responsible for a snug fit of the sash of the window structure and noise insulation, the absence of drafts. To choose a sealant for plastic windows, it is enough to know that high-quality sealing rubber or silicone is elastic, pliable, and odorless. To check the quality, you can compress the media and then release it. A good seal is easily pressed through and quickly returns to its original shape, there are no creases on it.
Plastic windows do not surprise anyone now, they are installed almost everywhere - from shops and offices to luxury apartments and three-story mansions. But their quality is completely different. If at the beginning of their “biography” plastic windows were exotic structures that looked like a degraded version of serial wooden ones, as they say, “soviet”, and practically equaled them in quality, then at a price they clearly went into the premium segment. But in the process of technological development, they have turned into a completely competitive tovary, which has a number of unique properties.
The device of a double-glazed window 1. Remote frames. 2. Glass. 3. Air gap. 4. Moisture-absorbing granulate. 5. Primary circuit sealant. 6. Sealant of the second circuit.Such a double-glazed window is called single-chamber, since there is only one air cavity. If you install another glass on the same gasket (distance frame), you get a two-chamber double-glazed window. Again, the thermal conductivity will be halved, the noise insulation will increase, but the light transmission will decrease by no more than a few percent. When choosing a double-glazed window, it must be remembered that its weight is 30% more than a single-chamber one, naturally, the cost is higher.
The product range of the brand is in demand in almost 50 countries around the world. Products are certified and comply with European standards. In order to confirm the quality of the PVC profile from Salamander marked.
PVC windows have recently appeared on the market, the cavities of which are not filled with air, but are filled with foamed heat insulators - expanded polystyrene, for example, or filled with fiberglass materials. Even with a relatively small number of chambers, their thermal insulation characteristics are much higher than air ones. But for now, their price is also higher.
