wedge perlite insulation board, also known as waterproof perlite insulation board, is made of expanded perlite bulk material as aggregate, adding waterproofing agent and binder for preparation, screening, pressure forming, drying processes.   expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It is inorganic, inert, neutral in ph, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°c (absolute zero) up to refractory applications at over 1000°c. ​ it also has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compound formulations. ​ perlite insulation products have the benefit of containing a rust inhibitor which is activated if the insulation comes into contact with moisture. The inhibitor neutralises any chlorides present, thereby greatly reducing, if not totally eliminating, corrossion under insulation (cui). advantages • light weight with very low bulk density. • waterproof with extremely high hydrophobicity. • low thermal conductivity. • most suitable for cryogenic applications -190°c. • high temperature insulation up to 650 °c. • fireproof, rot proof, damp proof, sound proof. • construction safety is simple and easy, roof and wall. • environmentally friendly. • water repellent, non-flammable, loose-pour insulant improves the thermal performance on masonry walls and floors. • corrossion under insulation (cui) resistant.

what is passive fire protection? passive fire protection are the systems made of non-combustible fire resistant materials and components used to minimise damage to life and property by confining the fire and stopping spread of fire for sufficient time to permit the safe evacuation of all occupants of the premises until the arrival of the fire officers. The person responsible for fire safety also has a duty of care towards any members of the emergency services, e.g. Fire fighters, who may have to enter the premises during the course of a fire; in slowing the spread of flames, smoke and hot gases, passive fire protection also serves to ensure the building remains as safe as possible for entry in this situation. ​ passive fire protection is achieved by maximising use of fire resistant structural and non structural building components and minimise use of combustible materials. Sealing of joints and concealed spaces with fire resistant sealant and other fire stopping materials. ​ what is fire resistance? fire resistance is a thermo-mechanical property of a building component that reflects the performance in terms of stability, integrity, and insulation requirements for a stated period against fire. ​ stability (load bearing capacity) ability of a load bearing component to withstand fire exposure without any loss of structural stability. ​ integrity resistance to penetration of flames, hot gases, and smoke. ​ insulation resistance to temperature rise on unexposed face upto a maximum 180 degree c at any single point and average temperature of 140 degree c. ​ at wedge we produce high performance and low cost passive fire protection systems.
