Specification requirements for roof extruded board insulation board
The Ministry of Public Security, Ministry of Housing and Urban-Rural Development (Gongtongzi No. 46) "Interim Regulations on Fire Protection for External Thermal Insulation Systems and Exterior Wall Decorations of Civil Buildings" have close regulations.
1. The inside is a closed bubble structure, which is an environmentally friendly thermal insulation material with high compression resistance, no water absorption, moisture resistance, airtightness, light weight, corrosion resistance, long service life, and low thermal conductivity.
2. The roof insulation layer of the aviation material warehouse and the maintenance hangar annex is made of 60-thick extruded polystyrene board, and the waterproof protection layer is 30-thick extruded board. After entering the site, the insulation boards are sorted and stacked, and measures must be taken to prevent rain and moisture.
3. The Ministry of Public Security, Ministry of Housing and Urban-Rural Development (Gongtongzi No. 46) "Interim Regulations on Fire Protection for External Thermal Insulation System and Exterior Wall Decoration of Civil Buildings" have close regulations. The roof insulation board has a fire protection requirement that is one lower fire rating than the outer wall insulation board.
Our company is the first manufacturer in China to develop and produce automatic PVC gypsum ceiling production line. It has fully automatic production line（single-side lamination type and double side lamination type), semi-automatic production line and economic type for customers to choose.
