Properties
• Fire rated “CLASS O” as per BS 476 Parts 6 & 7;
• Very low water vapor permeance (0 perms);
• Water tight due to the preapplied alupet foil;
• Very low water absorption rate (0.3% by volume);
• High thermal efficiency (λ24˚ C = 0.034 W/mK; λ46˚ C = 0.036 W/mK);
• Wide temperature range (from -50˚ C to +105˚ C);
• Chemical resistance – resistant of tubing to most chemicals (sodium, silica, fluoride, chloride, etc.);
• Antibacterial & antifungal;
• Environmental friendly – ODP = 0 and GWP < 5;
• Very low VOC emission level ( < 4 µg/m2/hr in 24 hours);
• Good mechanical resistance;
• Sound absorption properties;
• Perfect fit to most of the pipe sizes;
• Easy and fast to install;
• Aesthetical look.
