Perlite Concrete Roof Deck Insulation

It is also widely used as a separation board over existing roofs in recover installations.

Perlite concrete roof deck insulation.

Typical u values range from 0 21 btu h ft 2 f 1 19 w m 2 k for a 2 inch 50 8 mm 27 lb ft 3. Perlite concrete roof deck insulation is an ideal base for built up and single ply roofing systems. Provide minimum 1 inch 25 mm wide control joint through thickness of insulating concrete at building expansion joints in structural roof deck root projections. Perlite concrete is incombustible.

It has superior wind and fire resistance over other roof insulation materials and with the addition of polystyrene insulation board sandwiched in the perlite concrete high thermal resistance values are economically achieved. Delete 3 03 e 2 when perlite insulating concrete roof deck is designed as a diaphragm to resist horizontal forces and is installed over metal deck. Its weight can be varied in the range of 20 to 50 pounds per cubic foot depending on the mix design selected. All loose and protruding gravel must also be removed.

Finally permanence of perlite insulating concrete is another important factor. In fact its strength increases with age. This can be perlite concrete vermiculite concrete concrete made with polystyrene aggregate or cellular concrete. And the green community recognizes perlite enhanced products like lightweight insulating concrete roof decks as a high performance solution drawn from a natural material of nearly unlimited supply throughout the world.

Perlite insulating concrete consists of an appropriate mixture of portland cement perlite aggregate and water. Energyguard perlite roof insulation is designed to be used directly over structural roof decks. A good rigid insulation is insulating concrete which can be mixed and placed on the job. It is the ideal construction aggregate filler for masonry fill insulation roof decks floor systems and other significant areas that need insulation.

Expanded perlite s high insulating qualities light weight and versatility make it an essential part of the construction industry for loose fill insulation and lightweight insulating concrete. In recover applications all wet areas of the old roof must be removed. Perlite concrete is not subject to rot mildew or damage by water. Insulating values of a perlite concrete roofdeck depends on the density of the concrete mix that is prepared.

Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment.
