The secrets of the PVC profile structure.

There is no doubt that today the plastic profile is the best material for the production of window frames. Modern windows are comfortable to use, visually appealing and structurally reliable thanks to the PVC profile. The magnificent properties of this high-tech material allow to create designs of various shapes, including the ancient windows imitation. We would like to explain what features of the profile allow it to be so functional.

Everyone knows window profile has chambers inside. However, the number and shape of chambers can be different in dependence of type of window frames. The profile is hollow inside and divided into chambers, the number of which is three and more. Each compartment performs its own function. Their parameters are a result of the complex technical calculations.

The largest chamber is Located in the center, the main purpose of it is increasing rigidity. It is the metal reinforcing profile. Although PVC products are durable enough themselves, but can be susceptible to deformation under the influence of various factors. Deformations of this kind are usually not visually noticeable, however, strongly affect functionality. To avoid such changes, the PVC window frames are enhanced with reinforcing metal insert. There are types of profiles that do not require reinforcement. This occurs if the length of the sash is no more than 80 cm. Then the central chamber is empty. For windows of large size reinforcement is necessary.

In tomorrow's issue we will reveal other secrets of the internal structure of PVC profile.
