Wall Thermal Insulation Materials Fire Rating Division
Germany will be the issue of insulation fire is divided into three levels:
1,In laws and regulations clearly stipulates that more than 22 meters of the building is strictly prohibited the use of combustible insulation materials, polystyrene board wall thermal insulation materials can only be used for no more than 22 meters of buildings, more than 22 meters of the building most of the use of rock wool Wall insulation system.
2. In the European standard ETAG 004, rating of combustion performance A1-E for wall thermal insulation materials shall be graded according to EN 13501-1 using fire reaction test data and to specify the possibility of flame propagation in the insulation. In order to prevent the spread of flame, some countries have proposed the use of "fire barrier (fire barrier)" approach. The fire protection requirements for wall thermal insulation materials are based on laws and regulations and the applicable regulations applicable to the final use of buildings.
Germany fire rating is divided into A-B3 level (GB 8624-1997 non-equivalent), the standard polystyrene board material and insulation system fire rating should reach B1 level, according to EN 13501-1 standard, polystyrene board material and Insulation system to achieve B / C level requirements. Aerogel insulation materials reach A1.
3, polystyrene board wall thermal insulation materials in the polystyrene board thickness greater than 10mm, to meet the first level of the conditions of fire prevention structure, to the building fire safety requirements. Construction approach is to add in each window lintel and lintel mouth incombustible high-strength mineral wool fire isolation zone, the same thickness with the polystyrene board, the upward width ≥ 200mm; the length of the window should be extended than the sides ≥ 300mm.
