Tru-Guard™ Composite Technology

Therma-Tru’s Tru-Guard™ composite edge for Fiber-Classic® and Smooth-Star® doors helps to eliminate water absorption and enhances resistance to warp, rot, mold and wood-ingesting insects.
Therma-Tru Tru-Guard Composite Technology.
Resists Moisture & Humidity
Fiberglass doors with completely composite exteriors resist humidity and moisture on all six sides to help eliminate the risk of swelling and cracking.
Resists Mold & Rot
A fully composite door does not absorb or retain moisture helping to eliminate the risk of mold and rot anywhere on the door.
Resists Insects
With no exposed wood on the door, Therma-Tru fiberglass doors with completely composite exteriors help protect from wood-ingesting insects.
Six sides of protection for additional peace of mind. This composite edge is paired with a composite top and bottom rail and a fiberglass door skin to give six sides of composite protection.
