The USZ duct seals are made of self-adhesive polyethylene strips. They have temperature resistance up to 80˚C. The USZ-CER ceramic seals provide temperature resistance up to 1100˚C. The backing layer is made from aluminosilicate fiber felt. The adhesive material is based on modified acryl. The USZ and USZ-CER duct seals are installed in ductwork flanges and at the connections of AHUs to improve the air tightness of joints. The USZ-CER duct seals are perfect for airtight sealing of fire-resistant and refractory ducts.
