Rock Wool Board for Exterior Wall Thermal Insulation
Product Overview
Taishi rock wool board for external wall thermal insulation is specially designed and manufactured for external thermal insulation composite systems (ETICS) with thin plaster finish. It features high vertical tensile strength, excellent dimensional stability, high hydrophobic rate and low water absorption. Three grades including TSW140, TSW160 and TSW180 are available to meet diverse application requirements.

Wide Range of Applications
- Especially suitable for external wall thermal insulation thin plaster systems with rock wool boards.
- Applicable to external thermal insulation systems for curtain wall structures such as dry hung stone, aluminum plastic panels and aluminum single sheet panels.
- Used as fire stop belts in external wall insulation systems with non Class A insulation materials to improve the overall fire resistance of the whole system.
- Other insulation sites with high requirements for fire resistance, thermal insulation and water proof performance.
Packaging & Storage
For convenient construction, transportation and storage, the products are packed with polyethylene heat shrinkable film. Store indoors in dry and ventilated conditions; or cover with waterproof tarpaulins for outdoor storage.
