Can plastic windows replace fire windows?
Can not, fire window has fire rating, fire time requirements
Can not, plastic window The main chemical composition is PVC, so also called PVC profiles. It is easy to change at high temperatures! If the fire is blocked by plastic windows! But the temperature is greater than the capacity of steel windows will cause the plastic window melting and deformation! What do you know about it?
Plastic doors and windows are polychlorinated olefins (PVC) resin as the main raw material, plus a certain percentage of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion molding, and then by cutting, welding or screw Way to make doors and windows frame fan, equipped with sealing tape, tops, hardware, etc., at the same time to enhance the rigidity of the profile, more than a certain length of the cavity needs to fill the steel lining (stiffeners), so made the portal Windows, called steel doors and windows. Plastic window is easy to heat deformation, by the cold brittle, poor size and shape stability, often to use the glass to prevent the deformation of the window frame. So steel doors and windows can not replace the fire window.
