One of the biggest advantages of PVC windows is good thermal insulation. It has a low coefficient of thermal conductivity and retains heat in the rooms. PVC joinery does not require special maintenance and you will not have to paint it or treat it with special preparations.
PVC windows make condensation much harder than aluminium. However, this does not in any case mean that no condensation will form at high humidity above 50%. The most common areas of condensation are on the windows and the glass.
A linear extension of two to three millimetres per meter (there are cases of> 4 mm per meter linear extension) in the PVC profile makes it not particularly preferred. PVC windows can turn yellow (especially cheaper) after long exposure to strong direct sunlight.
Types of window hardware
In addition to all the other important features of the windows listed so far, there is another one that is of great importance. This is the hardware, that is, the locking elements of the windows. For many years of proper and trouble-free functioning of the windows, the choice of a good hardware plays an essential role.
The PVC joinery we offer allows installation of different types of fittings. Anti-theft hardware is extremely reliable because it offers a multi-point lock.
We advise you to avoid non-adjustable fittings, since inevitably after a year of operation, the rubber seals on the frame and on the sash slip. This requires clamping using an adjustable fitting. Adjustable fittings are also preferred because of the easy prophylaxis of opening parts - for example, against sagging.
The brands of hardware deserve attention are Mako, GU and Siegenia
If you are looking for windows for a ground floor or ground floor, it is a good idea to go for the so-called "security fittings". This is a very good solution that will prevent it from opening from the outside.
Today PVC is one of the best researched materials. The eco-balance of the entire life cycle of a PVC window gives a rating of "excellent" to this modern material.
