Aluminium foil tape also known as foil tape has adhesive on one side and a reflective aluminium foil on the other side. It is designed with an aggressive long lasting pressure-sensitive adhesive that shows superior bonding when exposed to both sub-zero and elevated temperatures. The UV resistant foil backing has excellent heat and light reflection to protect against high temperatures. It is an excellent barrier against moisture, dust, and flame which makes it ideal for harsh, long term outdoor environments. It is also crack resistant and flexible to lift around irregular or curved surfaces.Being a thermal conductor for heating or cooling efficiency, it acts as a water proofing barrier & air leakage protection.Our aluminium foil has excellent heat resistant quality, which makes it perfect for joining foil-faced fiberglass duct board or rock-wool insulation panels.It is also widely used in the construction industry for pipe lagging, and in the HVAC industry for duct sealing and insulation.Standard sizes: 2 inch x 15 yards (24 rolls/carton)2 inch x 20 yards (24 rolls/carton)3 inch x 15 yards (16 rolls/carton)3 inch x 20 yards (16 rolls/carton)*All sizes/microns are available upon request
