What are Grade-A waterproof inorganic thermal insulation materials?
There is a market confusion in Grade-A waterproof inorganic thermal insulation materials. The products mainly include Grade-A monomer material like roc wool and ultra-thin insulation board and Grade-A composite material. Many Grade-B materials wraaped with calcium silicate board or foam cement belongs to Grade-A material, such as phenolic aldehyde composite. Some foamed materials with filling also belongs to Grade-A material. However, there are few products with Grade-A qualification. Many manufacturers are working on the margins of the records with Grade-A fireproofing performance examining report. But this situation will not be too long.
Grade-A waterproof inorganic thermal insulation materials include: 1. external wall thermal insulation materials: (1) silicate thermal insulation material (2) gelatine powder polyphenyl granule (3) steel wire gauze picking cement cystosepiment (Estazolam plate) (4) extruded sheet; 2. roofing materials: (1) XPS Extruded sheet (2) EPS cystosepiment (3) perlite and perlite bricks (4) vermiculite brick; 3. heating and air conditioning material: PUR, rubberplastic sponge, polystyrene foam, glass wool, rock wool; 4. steel structure material: polystyrene, extruded board, polyurethane board, glass wool roll mat, etc.
1. Foam ceramic insulation board Foam ceramic insulation board is made of inorganic ceramic material by high temperature baking and is called ceramic insulation plate for short. 2. Composite cement foaming insulation board With cement, fly-ash and micro-silica, composite cement foaming insulation board is a kind of hole-closed lightweight hydrophobic insulation board made by foaming, maintenance,cuttign and processing. 3. Aerated concrete panel Using lightweight material, silicious material and foaming agent and so on, aerated concrete panel is a lightweight concrete panel made by high pressure steaming. 4. Rock wool board With natural igneous rock as material and thermosetting resin as binder, rock wool board is a panel made by melting in high temperature through centrifugation. I hope it can help you.
