Thanks to multiple carbamate radicals contained, polyurethane foam can tightly adhere to cement mortar and PVC plate, ensuring that the wind pressure to the window frame is evenly distributed among the four walls of the opening, instead of being withstood exclusively by spanker bolts on several fixed plates.
When filling and foaming, excessive foam will flow out, without causing deformation of the window frame.
Ultimately, polyurethane foam will constitute a half rigid closed cell material that blocks air flow, insulates sound waves, and resists shock.
As the foam cures, the protruding part can be cut and trimmed by a cutter easily.
As the foam cures, brushing the surface with coatings and emulsion paints can prevent aging due to exposure to ultraviolet.
Properly painted open-air PU foam will not be prone to aging, giving a service life up to 50 years.
