Scope

FLS composite insulation boards are prefabricated in factories and used as panel products for external insulation of building walls. They consist of a protective layer, an insulation layer, a base lining, and a fire-resistant material layer and adhesive layer as needed. They can be divided into Type I and Type II, with product codes FLS-I and FLS-II. The protective layer is located on the outside of the FLS composite insulation board, serving as a crack-resistant mortar layer that balances inter-layer stress and strain, enhances fire safety during construction, and provides protection during storage and transportation. The fire-resistant material layer is located on the outside of the insulation layer of the FLS composite insulation board and consists of a heat-resistant composite polystyrene foam insulation board with A-class combustion performance, rock wool strips, or polyurethane foam granule mortar, serving as a fire-resistant protection layer. The fire-resistant structure layer, which consists of the protective layer and the fire-resistant material layer and has a total thickness of not less than 50mm, improves the fire resistance of the FLS composite insulation board system and prevents the spread of flames along the outer wall. The base lining is located on the inside of the FLS composite insulation board, serving as a crack-resistant mortar layer that improves adhesion to the base layer, enhances fire safety, and provides protection during storage and transportation. The plaster layer is applied on the outside of the protective layer of the FLS composite insulation board, with an alkali-resistant mesh cloth sandwiched in between, serving as a structure layer with crack-resistant, waterproof, impact-resistant, and fire-resistant functions. The connectors are made of a composite structure of metal and engineering plastics (hot-melted), which are dedicated components for effectively connecting the FLS composite insulation board to the base wall
