Insulation energy-saving technology:
Light steel structure In order to ensure the thermal insulation effect, in the building of the external walls and roof insulation materials used in the long-term use and can heat insulation. In addition to wall-to-wall masonry-filled fiberglass grids, the light-steel structure houses a layer of thermal insulation on the outside of the wall to effectively cut off heat bridges through the wall-to-wall panels. Filling glass fiber within the joystick to reduce the heat transfer through the floor; all walls of the wall between the walls are filled with glass fiber to reduce the heat transfer between the walls of households.
Fire protection technology:
Light steel structure of a most critical problem is the application of fire protection technology, light steel structure residential fire resistance rating of four. The light-weight steel structure houses the fire-resistant gypsum board on both sides of the wall and the ceiling of the floor. It is protected by a 25.4-mm thick (1-inch) gypsum board for ordinary firewalls and household walls to achieve an hour of fire protection. , The other in the wall between the wall between the floor and the floor of the glass filled with glass for the fire and heat transfer also played a positive role in protection.
Soundproofing:
Light steel structure in the external walls and floor cover joins between the glass wool, effectively prevent the air-borne audio part, and for solid-borne impact sound, the following construction: for household wall with two wall columns With the middle of the gap between the two walls; and for the ceiling with fixed gypsum board keel, with a small slot with a flexible structure to effectively reduce the spread of solid floor between the sound.
