WTI's Pre Insulated Duct achieves the highest standards in fire safety. WTI Duct's Flame Spread Index (FSI) is < 25 and Smoke Development Index (SDI) is < 25 both of which complt to the highest standards and achieve the highest Class O rating
Low Weight
Weighs up to 75% less than galvanized sheet steel ductwork.
Energy Saver
Very good insulation core with U-Value at 0.019 W/m2K and low air leakage help reduce energy cost of HVAC system b4 25%.
Faster Installation Speed
Low weight material for fast insulation, and the duct panels pre insulated so elimi_ nates the need to insulate on site
