Phenolic foam insulation layer adopts advanced foaming technology with fine bubble and uniform density, strength and thermal insulation properties are guaranteed.The use of phenolic-based foams in insulation is growing, as these are more stable in the case of fire and release almost no emissions. The mining/tunnelling industries use mining foam to fill in cracks and stabilise crumbling rock faces.
VENTECH phenolic insulation foam board for wall/roof system is manufactured from Phenolic Foam Pre-insulated Duct Panels and Accessories by a set of special tools. The Panels consist of panel thickness 20mm, with double-faced 60um aluminium foil, both sides faced with aluminum foil, aluminum sheet, etc.
Hvac pre-insulated phenolic air duct panel is accomplished by following a standardised procedure. The process is the same regardless of the shape of the duct element: tracing, cutting, gluing, folding, taping, flangeing & reinforcement and sealing.
