Isover U Protect Accessories

The Isover U Protect system has been tested in accordance to EN 1366-1 and EN 1366-8 and assessed against the criteria in BS 476: Part 24. It offers up to 2 hours passive fire protection in HVAC ventilation and smoke extract ducts as well as up to 1 hour passive fire protection for kitchen ducts.

The fire performance of the system cannot be substantiated if alternative system components are substituted.

• Protect Black Tape - self-adhesive black aluminium tape for covering the insulation slab edges for rectangular ducts.
• Protect BSF Intumescent Paint - used for sealing all penetrations - solvent free and pH neutral, white aqueous intumescent dispersion
• Protect BSK Adhesive - Non-combustible, inorganic adhesive based on alkaline sodium silicate for gluing the insulation to the wall, floor or ceiling. It is only required at penetration details rather than at every insulation joint.
• Fire Protect Screws - spiral shaped screws made of galvanised steel to fix U Protect Slabs on rectangular ductwork

The fire resistance is also dependent on the application, thicknesses of insulation and the method of installation.
