The senior external wall insulation must choose the Class A non-combustible material
On December 3, the Ministry of Public Security Fire Bureau published the announcement of the abolition of the 65 No. But how to interpret different opinions. In particular, how the the perlite industry's prospects? The direction of the future development? Each perlite practitioners eager to know the problem, the General Lee, Chief Engineer of Kay think future perlite application will only be more and more widely in the field of building insulation material may be more focused on the high-level and roof insulation.
Sure, Jiangsu Provincial Public Security Bureau, the Provincial Department of Housing and Urban-Rural Construction Department jointly issued the "Jiangsu Province of exterior wall insulation materials fire Interim Provisions" (hereinafter referred to as the regulations), the specification of Jiangsu Province, the new wall insulation materials, renovation and expansion of civil construction The design and use of fire protection, personnel-intensive places special emphasis on the A-grade insulation materials.
According to the relevant person in charge of the Nanjing Public Security Fire built-trial Division, A-level insulation materials generally inorganic insulation materials, such as glass beads, expanded perlite, non-combustible material. Class B insulation materials is a relatively low level.
According to reports, the building's exterior, no cavity between the insulation material and the primary wall, decorative layer, the residential building height greater than 54m, the combustion performance of insulation materials shall be Class A; building height not greater than 54m the combustion performance of insulation materials should not be less than the B1 level. Building other than residential construction, the building of the setting crowded places, should be used A-grade insulation materials; crowded places do not set the building when the building height greater than 50m, the combustion performance of insulation materials for Grade A; building height not greater than 50m, the combustion performance of insulation materials should not be less than the B1 level. Cavity between the building exterior insulation system with the primary wall, decorative layer, when the building height greater than 24m, the combustion performance of insulation materials for Grade A; When the height of the building is not greater than 24m, the insulation the burning behavior of the material should not be less than the B1 level. Fire blocking material blocking the cavity between the insulation system, the primary wall, decorative layer at each floor.
Building exterior insulation systems, the crowded places and all types of building evacuation stairways, aisles of refuge, refuge, refuge floors, A grade insulation material; other building, place or location, low smoke, low The poison and combustion performance of not less than the B1 level of insulation materials.
Comparison of energy-saving and life-safety, the value of life above all else! Perlite, glass beads, and other inorganic insulation materials With the continuous improvement of the safety awareness of people's lives, it just gets to flourish. The future of the field of building insulation will certainly flourishing, leading the trend!
