Things Worth knowing while choosing new windows for your house
One of the most important elements of building every new house is the choosing adequate windows. Among the basic elements that should be focused on are quality and class of the new windows, the type of glass used and the window’s thermal insulation properties.
What should you know about the class of windows? First of all that the PVC joinery is profile-based and that profiles can be made in various classes e.g. A, B, C etc. The highest of all classes is A. Class A means that the external surface of a window is 3mm thick, which ensures stability and durability of windows and a higher protection against noise and temperature fluctuations. Thinner profiles (class B and C) are not so resistant to damage and might be much more exposed to cracking corners and deformations
Window glass is also an important element to consider Insulated glass windows are most popular these days. They consist of two or more glass surfaces which are separated with a distancing frame made of e.g. aluminium. A special frame, so called thermal frame made of hardened steel can be placed between the glass surfaces, which effectively lowers heat losses up to 10%, and reduces condensation.
Comfort of use can be also enhanced by a good choice of additional elements. It is now standard to have the window fitted with the blockade of a mispositioned handle, which makes it impossible for the casement to fall out when the handle is placed not quite where it should.
Flyscreens are also a practical choice, as are air nozzles which automatically regulate humidity levels in a room.
Other interesting options are for example a low balcony threshold fitted in order to avoid stumbling over the higher option or a shut lock that enables one to close a balcony or garden door from the outside without using a door handle. It is also worth furnishing your windows with anti-burglar devices, such as anti-burglar latches or handles with a lock. The best solution is always fitting your house with certified anti-burglar windows which, apart from the elements already mentioned, are also fitted with the glass of higher resistance made of permanently joined float glass surfaces and four anti-burglar foils that are very difficult to tear.
Thermal Transfer Coefficient (U) is also a very important parameter that ought to be taken into consideration. It should be calculated not only for the entire window but also for the window glass. The coefficient should be measured individually for each window, for example when it is being priced.
So making a window purchasing decision should not be done without a thorough analysis taking into the account such guidelines as the overall quality of products, class of window profiles, glass panel, choice and price of accessories and thermal insulation properties. It is also worth considering the experience of the company you might be choosing, their presence on the market and the certificates which have been granted to the firm. Windows are an investment for many years to come. It is therefore worth investing in the highest quality, functionality and best design.
