What is rock wool insulation felt

Rock wool insulation felt is made of basalt and other natural ore as the main raw material, melted into fiber by high temperature, and added with appropriate amount of binder. This product is suitable for the insulation of tank containers and large diameter pipes.

Rock wool insulation felt has excellent thermal insulation performance, convenient construction and installation, remarkable energy saving effect, and high performance and price ratio.

Rock wool insulation felt is a kind of high quality thermal insulation material with low thermal conductivity. Applicable to large and medium-diameter pipelines; medium and small storage tanks and arc surface or irregular surface equipment with small surface curvature radius, building air conditioning pipeline insulation and anti-dew and wall sound absorption and heat preservation.

Attention should be paid to the fixing and support of the insulation material during the design and construction. If the insulation layer is larger than 80 mm, it is recommended to use double insulation to reduce the heat loss in the joint at the joint. Due to the high thermal conductivity of water, the thermal conductivity of water will increase significantly after it enters the rock wool product. Therefore, it is necessary to prevent moisture from entering the rock wool product during design and construction.
