How to choose PVC doors and windows
Compared to a normal window, wood, PVC windows, bring us many advantages
- require no maintenance works (eg to be painted)
- provide enhanced thermal insulation
- Increased sound insulation
- Sustainability (through the guarantee for a few decades from PVC profiles)
- and not least reliability
When it comes to carpentry will choose the best for your home, you should note that the market there are several classes of models and cataloging of these profiles.
Depending on the thickness of the outer wall of the main profile, for example, they fall into three classes A, B and C. Class A minimum thickness of the main wall should be less than or equal to 2.8 mm and greater than or visible surface equal to 2.5 mm surface that is not seen. For Class B, the minimum value of the main wall should be less than or equal to 2.5 mm for the visible surface and greater than or equal to 2.0 mm surface that is not seen. This classification after wall thickness profiles aims to illustrate variations important profile and the window for various applications common in Europe.
Also it shows the standard quality requirements such as layout, dimensions and tolerances, weight, shrinkage, mechanical shock resistance, behavior after heating to 150 °, aging resistance and weldability test.
For a quick comparison, we must know that the price difference between a profile of Class A and one Class B is 10-12 percent, but the life of the class A rose by at least 20% over that of class B.
Maintenance of PVC doors and windows
PVC windows and doors, as any other construction elements are subject to wear, dust and dirt.
For optimum performance, we recommend cleaning windows and maintenance.
Maintenance of PVC joinery profiles is easily accomplished and cleaning is done with traditional detergents.
CAREFUL! It is not recommended for cleaning profiles of solid objects or materials that could damage or scratch the woodwork.
Hardware maintenance is also recommended at least once a year, she consisting tightening all screws (the handle, hinges) and lubricate all moving parts and locking points.
The purpose ventilate rooms
Reducing air humidity will not longer be the only requirement imposed a modern ventilation of rooms. A continuous and sufficient air exchange is extremely important for the residents of a building. For this, the following criteria must be met:
- regulate indoor air humidity
- replacement of air breathing
- eliminating odors and harmful substances
- regulate the temperature in the inner space
- INLET air installations dependent on room air
The most effective air exchange in the room is full airing. Window sash is fully open and the air exchange occurs within 4 to 10 minutes. If complete ventilation energy losses are minimal. Because air exchange happens very quickly not cooling the building parts.
If cross ventilation and air exchange occurs faster. In an interval of 2-4 minutes the room air is completely changed. To this end, all windows and doors must be open, so as to form a stream of air.
If the airflow through the vents, the window is open only to a certain extent. Tilt-standard dump windows are swung usually sash. With ventilation slots is aimed only through an exchange of air conditioning; therefore, maintaining state for extended durations Tipping is correlated with energy loss in winter. Due to strong cooling of the windowsill, danger and disturbance by condensation is higher.
