Abstract:
The experiences gained in European countries
and the United States have shown that the PVCwindow
meets a great many requirements of our
time.
The raw material PVC has proved to be an
ideal material for windows. In the course of recent
years, various standards have been developed
for PVC-windows and now constitute a regular
quality system. PVC-windows have all the
positive qualities of wood/aluminium and steel
windows, but with regard to their negative fea-tures, PVC-windows are quite an improvement.
