1.Insulating gaskets are placed along the edge of the board to effectively blocked the heat transfer at the joints of the boards and enhance the overall thermal insulation performance of the wall.
2.An even injection of weather-resistant sealant ensures joints are sealed to prevent moisture and air penetration while providing sufficient bond strength to accommodate temperature changes and minor movements of the building.
3.The EPDM strip is inserted in as the outermost layer of protection. With its excellent elasticity and durability, it provides a long-lasting and reliable sealing effect for the wall.
