1) External wall insulation yellow rock wool 2) especially for External wall thermal insulation plastered system 3) A1 grade

External wall thermal insulation board is designed for outer wall external thermal insulation system of thin plastering and tailor-made.

Suitable for brick or concrete structure wall built or building external wall thermal insulation and building energy saving. In addition, rock wool strip is building fireproof isolation belt of the best fire insulation materials, external wall thermal insulation and combustion performance was not up to A-level insulation materials ( such as: Polystyrene, supporting the use of XPS plate ) can improve the building fire prevention function.
