Gap Fillers and PU Foam
Gap fillers and PU Foam products are developed specially for use with any of our UPVC products. PU foam can be used to fill stubborn difficult areas providing a permanent weatherproof seal. Once the foam has expanded and dried, any reminding foam can be cut off with a sharp knife. PU Foam can be purchased either an aerosol gun which will require a foam gun to operate, or an handheld can.
Normal fillers can be used for draught proofing and filling of cracks, as it will not shrink or crack. Once dried it will be ready to paint.
