One of the most critical issues in light steel construction is the application of fire protection technology. Matt's light steel structure house is covered with fireproof gypsum board on both sides of the wall and the ceiling of the floor. It is protected by 25.4 mm thick (1å‹) gypsum board for ordinary firewall and household wall to meet the fire protection requirement of 1 hour. In addition, the glass fiber filled between the wall columns and the floor joists also has a positive protective effect on fire prevention and heat transfer.
