Product Description
Hollyseal® PVC foam glazing tape is a PVC foam with a density of 350±50 kg/m3, coated on both sides with a high tack acrylic adhesive and with a blue film liner for easy peeling. It has a closed cell structure that allows the curing of structural silicon on all sides of the joint. It is commonly used to form a seal between double glazed units and frames in windows and doors.
