About Coolite
Coolite is a construction grade perlite of very low density, meeting the requirements of ASTM C 332. Portland cement mixes using coolite as the sole aggregates, or using Coolite combined with other aggregates have been designed to produce ultra lightweight concrete with dry densities from 22 to 80 lbs. per cubic foot and compressive strength with range between 90 and 2,500 psi. Insulation value increase dramatically as the density decreases. Coolite combined with portland cement and water produces an ultra- lightweight concrete that is used for insulating roofdeck, curtain wall systems and for a variety of permanent insulating application. An air entraining agent is used to improve the workability and to control water content and insulation value.
Construction Applications
Because of perlite's outstanding insulating characteristics and lightweight, it is widely used as a loose-fill insulation in masonry construction. In this application, free-flowing perlite loose-fill masonry insulation is poured into the cavities of concrete block where it completely fills all cores, crevices, mortar areas and ear holes. In addition to providing thermal insulation, perlite enhances fire ratings, reduces noise transmission and it is rot, vermin and termite resistant. Perlite is also ideal for insulating low temperature and cryogenic vessels. When perlite is used as an aggregate in concrete; a lightweight, fire resistant, insulating concrete is produced that is ideal for roofdecks and other applications. Perlite can also be used as an aggregate in Portland cement and gypsum plasters for exterior applications and for the fire protection of beams and columns. Other construction applications include under-floor insulation, chimney linings, paint texturing, gypsum boards, ceiling tiles and roof insulation boards. texturing, gypsum boards, ceiling tiles and roof insulation boards.
- Non-Combustible
- Superior Fire-ratings
- Nailable roofing base
- Lightweight and Durable
- Reduces sound transmission
- Superior Thermal Performance
- Smooth, slope-to-drain surface
B. For wall plastering
- Lightweight: it weighs approximately 60% less than ordinary sand plaster, saving about 1 ton (900 kgs) for every 84 square meter of material applied 1/2" thick. This weight saving makes perlite portland cement plaster suitable for paneled curtain wall construction.
- Insulation: 4 times more resistant to heat transmission than sanded plaster thus permitting savings in air conditioning.
- Fire Rated: Non-combustible and non-toxic, provides up to 5 hours fire protection with minimum weight and thickness.
C. Lightweight floor fills
Coolite aggregate concrete fill over wood, cellular steel or structural concrete floors permits substantial reduction in dead load. Ceramic tiles, marble slabs or terrazzo may be applied directly over this fill.
- High rise building under construction
- Building under renovations
D. Lightweight hollow blocks
Coolite hollow blocks (CHB) consist of portland cement and expanded perlite, manufactured in the same shape, dimension and design as ordinary hollow blocks.
Used for:
- Firewall
- Insulation
- Room partition
- Bank Vault Fire Protection
- Cold Storage
- Walls in residential,commercial,industrial and high rise buildings where dead load can be reduced
-
Music recording studios,theaters and auditorium where heat, cold and sound insulation ia a paramount concern
Advantages of Coolite
Non-Toxic
Coolite contains no asbestos. Chemically inert and has pH factor of seven.
Permanently Lightweight
As the weight is about 3 to 7 times lighter than ordinary concrete, Coolite is very light in weight and ideal for easy handling and its density can be adaptable to meet different design requirements.
Tested Insulation Efficiency
Various testing conducted has shown conclusively that coolite perlite insulating material demonstrates long lasting and high insulation properties.
Enviroment Friendly
Coolite does not contain any CFC's and other harmful chemicals that can damage the enviroment.
Excellent Fire Ratings
Coolite is non-combustible, cannot burn or aid the spread of fire and offer fire ratings from 1 to 5 hours therefore ideal for factory and high-rise buildings.
