Thermatite Door Systems are built stronger with Neufoam™ technology – a continuous foaming process that renders cavity-free sections. No air pockets inside the panel ensures superior adhesion of our CFC/HCFC-free polyurethane insulation to the steel skin, preventing delamination and providing exceptional structural integrity. The door has a higher strength-to-weight ratio, offers a better thermal barrier (higher R-Value) and resists deflection. Sections feature thermal breaks and two continuous replaceable seals to minimize air flow.
