Frequently Asked Question
Do you have any question?
UPVC windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., are extruded to form the material, and then cut, welded or screwed production.
UPVC windows are a new generation of window materials, which have the advantages of high wind pressure resistance, good air and water tightness, small air and rain penetration, low heat transfer coefficient, heat preservation and energy saving, sound insulation, and resistance to aging.
In addition to the problem of filling materials, you must pay attention to the size design when installing. The size of the upvc window should be smaller than the size of the hole. At the same time, the size of the window components and the size of the drain hole of the window must be taken into consideration.
