What glass beads insulation board Fire Barrier?
The Fire Barrier apply exterior insulation system at the grassroots to the concrete or masonry wall, the use of combustible insulation materials mainly insulation material. Placed on the outside of the external walls of the building, set in combustible insulation materials exterior insulation and finish systems, distributed according to the horizontal direction, the height direction of a certain size, and prevent the spread of fire building exterior insulation fire resistant construction. The Fire Barrier insulation material core material combustion performance levels for A-level. Fire Barrier should adopt the factory prefabricated products on-site installation. Grade A non-combustible material in Kay glass beads of insulation board to take the national recommended glass beads, using certain adhesives repression, product performance to meet the requirements of the Ministry of Construction on Fire Barrier specific properties are as follows:
Kay glass beads of insulation board
