This reinforcing fiberglass tape is designed to create internal and external corner joints and connecting seams of drywall structures, where it strengthens sealed joints and prevents the formation of cracks. It increases the strength of exposed areas such as openings for windows, doors and lights. It reinforces the longitudinal joints of partitions and single and double-sided structures, suspended ceilings and attic sheathing. The advantage is it can be sanded and coated. The thermal resistance of the tape is -35°C to +90°C.
