EXEWOOL Curtain wall rock wool boards are specially designed for various dry-hanging curtain wall systems that require soundproof, fireproof, and thermal insulation. The boards are available in different thicknesses to meet diverse specifications and new construction applications. Which have excellent dimensional stability, a service life equal to the life of the building, and can be coated with fireproof aluminum foil and other finishes.
The black fireproof rock wool board is specially designed for curtain wall system with higher fireproof and heat preservation requirements. It's melting temperature is above 1150ºC with better thermal insulation and fireproof performance. The appearance of this product is dark brown, and the surface can be pasted with fireproof aluminum foil and other finishing layers.

Application
1. Black fireproof rock wool board can be used alone or as part of the system to apply to the gap between the curtain wall and partition wall fire blocking and fireproof partition wall, fire doors, fire ceiling.
2. Applied between curtain wall and structural floor, attached to the wall as heat insulation and noise reduction layer.
3. Low-density curtain wall fireproof insulation rock wool board and black fireproof rock wool board can also be used to fill a variety of through-wall pipelines or irregularly shaped through-wall objects produced by the gap fire blocking, etc., which is easy to cut, easy to install.
