what is the grading standards of external wall thermal insulation materials?
What is the grading standards of external wall thermal insulation materials? summarizing the three versions of GB8624 (1997,2006,2011) external wall insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. the dividing is based on many technical indicators. It takes time to explain for It is professional and technical. For details, please contact Qingdao Shan Textile Instrument. they specialized in external wall insulation fire rating tester.
1. combustion performance of insulation material rates A EPS sea capacity module, rock wool, glass wool, foam glass, ceramic foam, foam cement, perlite obturator, etc. 2. combustion performance of insulation materials rates B1 Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule3 combustion performance of insulation material rates B2 Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 A graded insulation material is fire proof, but its thermal insulation performance is not so as organic XPS \ EPS. I feel the best insulation materials are Hairong EPS module. it is both insulating and fireproof and cheap. Insulation materials in the domestic market each has its shortcomings. Choose of materials should based on actualities in construction.
external wall thermal insulation materials are divided according to Fire rating: 1, the combustion performance of insulation materials rates A. inorganic fiber spray coating, glass wool, foam glass, foamed ceramic , rock wool, foam cement, obturator perlite 2, the combustion performance of insulation materials rates B1: Extruded polystyrene board (XPS)after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polyphenyl granule.3, combustion performance of insulation material rates B2. Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
