Roof Thermal Rockwool Board

Short Description:

Hebang roof thermal insulation rock wool board is specially made for flat roof system (especially flexible water-proof roof system) with thermal insulation, noise absorption and fire prevention functions of industrial and civil roofs. It has excellent compression resistance, high load, anti-aging and weather resistance, which can not only fully bear the movement of workers during construction, overhaul and maintenance, but also ensure long-term and stable thermal insulation, sound absorption and noise reduction functions in the roof system. It is often used in automobile factories, airports and large-scale buildings with strict fire prevention requirements.

Typical Structure

Basic Structure and Hierarchical Specification of a Flexible Waterproof Rockwool Roof

1. Waterproof membrane

2. Rockwool insulation

3. Vapour barrier layer

4. Metal deck or concrete

Single-layer Rockwool Insulation

Rockwool boards with proper compressive strengths and proper anti-load performance should be used in light of the roof design requirements.

Multi-layer Rockwool Insulation

Rockwool boards with higher bearing ability may beused on the upper layer and such products with lower bearing ability like high-strength roof boards on thelower layer,multi-layer combined rockwool insulation structures can not only meet the bearing ability requirements of roofs but also avoid heat leakage at the joints of single-layer heat preserving structures and make the heat preservation construction costs and energy saving requirements of roofs reasonable. Thus, we believe multi-layer combined rockwool insulation structures are an extremely good system solution.

APPLICATIONS

Hebang roof rockwool boards are usually applied to the steel structure system with a higher compressive strength requirement. They are usually used as heat preserving layers and bearing layers to form roof thermal preservation structure systems with flexible waterproof rolls and breathing layers. Flexible waterproof roof systems are extensively applied in the steel or concrete roof waterproofing systems of industrial factory buildings, airports, train stations, bus stations, large shopping malls, stadiums, gymnasiums, warehousing facilities, etc.
