It is used around the world, offering cost savings throughout the supply process. Its lightweight means for lower transport, application and structural costs and once emplaced it offers excellent insulation against noise, fire, vermin and climate.
Laboratory and field tests have proven perlite/sand concrete is suitable for use over structural forms such as corrugated steel, rib steel or cellular steel floor units and plywood sub-floors and ideal as a base for a wide variety of floor materials including carpet, tiles and hardwoods.
Perlite based plaster has endless unique properties accounting for its ready acceptance and widespread use by many leading architects, general contractors and plastering contractors.
• - Light weight: Perlite plaster is only one third the weight of sanded plaster. Lightness in weight also permits the plasterer to maintain optimum production for the full working day with much less effort.
• - Fireproofing: National bodies have been swift to recognise the advantages of superior fire protection and potential cost reductions afforded by perlite plaster fireproofing and have modernised codes to take advantage of this. Laboratory fire tests have resulted in ratings as high as 4 hours for plaster containing perlite .
• - Insulating: Perlite possesses millions of tiny air particles and in turn permanent insulation cavities that reduce heat transmission losses. Perlite adds a high thermal insulation value to plaster.
• - Better workability: Perlite plaster’s sharpness has similar workability to that of sand.
• - Crack resistant: Perlite plaster has a high degree of resiliency ensuring less cracking.
