Description
Expanding foam tape is used specifically for the glazing industry. It is an open cell polyeurethane foam impregnated with flame retardent acrylic resin backed with an acrylic adhesive on one side. Expanding foam tape is a type of sealing material made from pre-compressed foam that gradually expands once opened and exposed to air after application. It’s commonly used in construction and home improvement projects to seal joints, gaps or seams against air, water, dust and noise. Heavily impregnated with chemically stabilised acrylics creating flame retardant properties, Expanding foam tape remains permanently elastic and will continually self adjust after installation to keep gaps closed.
An excellent expanding joint sealing alternative to polyurethane aerosol foam due to its clean and easy application as well as its cost-efficiency. This product is ideal for professional and DIY use for the installation of windows and door frames as well as for joining structural elements in residential and commercial construction. The measured performance of expanding foam tape is rated at 600 Pascals, or driving rain, at 25 per cent decompression. This product allows for sufficient joint ventilation which prevents the accumulation of mildew, has high UV resistance, and ages well without noticeable cracking or splitting over the years. This makes it ideal in climates with seasonal changes and noticeable expansion and contraction in joints. This product is Fire Rated to B1 Classification.
The tighter the tolerance between the profile and the glass (i.e the thickness of the expansion tape) will achieve a better water and air tight seal. If the tape is allowed to go to full expansion then a lower air and water tight seal will be achieved.
