1. What do we need to know before ordering windows?

PVC windows profiles are resistant to climate change, protected against UV-radiation, and the colors are long-lasting. Thanks to its multi-cell structure, it has excellent heat - and soundproofing properties and complies with all requirements of a modern building product.

Aluminium is a versatile light material resistant to weather and corrosion. This makes it suitable material for making windows, show windows, entrance doors and internal walls. Aluminium profiles are of two types: with thermal break and without thermal break. For exterior glazing the aluminum profiles used are with thermal break. Aluminium profiles without thermal break are suitable for making walls, doors and other internal structures.

Choosing windows profiles - aluminum or PVC, is a matter of personal choice.

• origin of profiles - a first step, which ensures reliability and longevity of the windows. For polyvinyl chloride (PVC windows) you should know it is polymer material and a very good insulator of temperature. The greater the number of cells in the PVC profile, the better the insulation. To achieve good thermal insulation for aluminum profiles, they must have a thermal break, i.e. having a plastic insert, which divides the profile into two parts, thereby distinguishing internal from external space. Profiles can have different colors, it depends entirely on your preferences.

• glazing – they can be also different - two or three clear-glass windows, low emission glass, windows with colored glass, glass with Stopsol, etc.

• fittings - modern fittings allows each window to be opened in two planes - a combination of horizontal and vertical axis, which is certainly convenient.

• seals - do not forget that whether PVC or aluminum - wing and frame isolation is achieved through a set of seals. For best results - they are all required.

• drainage - gutter channels help to drain water splashed on the window.

• the installation is done with fasteners and polyurethane foam. If you anticipate after the installation of window having stone and / or other coating materials placed, you must tell the representative of the company who does the measuring, so the gauge of the window is consistent with subsequent works.

2. Is there a price per square meter?

Price per square meter do not give you an accurate information about the price of your window. To obtain the correct price should take into consideration:

1. size
2. type of profile
3. number of cells
4. color
5. ways of opening
6. types of fittings
7. type of glass

3. Tips for maintaining the PVC windows.

- Protective film must be removed immediately after completion of finishing works. Otherwise, the external protective film burns from the sun and its removal becomes difficult.
- It is necessary periodically to lubricate all hinges and locking mechanisms on doors and windows.
- Do not allow the entry of sand, lime, mortar, etc.. pollutants in the mechanisms.
- Maintain gaskets clean to prevent accumulation of dust on them. There are special liquids which protect the rubber seal from the weather and make them more flexible.
- The windows are made of plastic profiles which are resistant to sunlight and weather. Ordinary detergents, which do not contain abrasive additives, acids and strong solvents, can be used for washing windows and frames.

4. What causes condensation?

Replacement of old windows with modern ones gives better results and may lead to extreme sealing of the house and condensation and mold. Condensation requires two factors - moist air and cool surface. As a result of breathing, cooking, bathing, laundry, flowers, etc.. humidity of indoor air rises. When moist air reaches the cold surfaces such as exterior walls, window frames and windows, moisture in it condenses on them. Old windows do not seal well and permit, even when closed, slow air exchange - moist air leaves the room along with the heat. You should ventilate the rooms several times a day for a short period. Ventilation of the bathroom must be carried out through direct opening or through a vent.

5. Low-emission glass (K-glass)

Low emission glass are created for the purpose of lowering energy loss by radiation. These are windows applied with hot spray of metal oxides (mostly silver, titanium or other precious metals) creating very thin reflective layer. The function of this layer, only a few microns thick, is to retain heat inside. When K-glass is correctly installed in the room with a reflective coating inside the glass, it begins to act as a mirror to heat rays, which are in the infrared spectrum. Sunlight is mostly short-wave and all the energy it carries, passes easily through glass and enters the building. However, when the walls and furniture are heated by it, they begin to emit heat, which has a large wavelength and can not leave the room back out the window. All heaters emit infrared heat and not only heating appliances, but the burners, monitors, lighting, even the human body. Overall, the advantages of K-glass are indisputable - almost 30% more insulation, i.e. it is much less likely for condensation to occur on the inside wall of glass, you can cut fuel bills and have better indoor comfort.
