Fibrous insulation combined with fire protection
Short notice given only substantially as folllows: A US manufacturer of building materials has developed a fibre-based insulation that it claims has greater flame resistance than existing products. With headquarters in Valley Forge, Pennsylvania, CertainTeed Corp is a part of the Saint-Gobain Group, a producer, processor and distributor of advanced materials (such as glass, ceramics, plastics and cast iron). In European Patent EP 1 743 060, CertainTeed reveals that its insulation is a fibrous mineral (such as fibre glass or glass wool) mixed with a compound containing phosphate and a refractory mineral filler. Numerous phosphate-containing compounds are suitable, though inorganic phosphate salts are preferred, including mono- and diammonium phosphates. Also, a range of mineral fillers can be used, though again the Patent notes a preference, in this case for fine particles of refractory mineral fillers, such as alumina or silica. In one specific examples cited, CertainTeed says it used about equal amounts of monoammonium phosphate and alumina (or aluminium sulphate). Combined these components should be at least 6%, or better still I I % or more, of the total weight of the insulation. Fibrous insulation is often used in environments where fire is a hazard, including homes, offices, manufacturing facilities and vehicles. Existing insulation can melt, burn or allow the passage of flame when exposed to fire, CertainTeed says.
