Wide Range of Applications
- Especially suitable for external wall thermal insulation thinplaster systems with rock wool boards.
- Applicable to external thermal insulation systems for curtainwall structures such as dryhung stone, aluminumplastic panels and aluminum singlesheet panels.
- Used as firestop belts in external wall insulation systems with nonClassA insulation materials to improve the overall fire resistance of the whole system.
- Other insulation sites with high requirements for fire resistance, thermal insulation and waterproof performance.
Packaging & Storage
For convenient construction, transportation and storage, the products are packed with polyethylene heatshrinkable film. Store indoors in dry and ventilated conditions; or cover with waterproof tarpaulins for outdoor storage.
