Perlite Tapered Roof Insulation

Dual purpose structural deck and insulating planks.

Perlite tapered roof insulation.

It is readily available in the two most popular and efficient tapers 1 8 3 18 mm per foot 305 mm 1 and 1 4 6 35 mm per foot 3 18 mm 2. Perlite roof insulation its insulating efficiency. Some tapered insulation is formed with a slope and only needs to be pieced together during the installation process. When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system.

Factory tapered insulation board systems are the ones most commonly used because they are inexpensive and easy to use. Energyguard perlite roof insulation is designed to be used directly over structural roof decks. Polyisocyanurate rigid foam board insulation is shown installed in a tapered design over a flat roof. It is also widely used as a separation board over existing roofs in recover installations.

Energyguard perlite roof insulation is available in 2 x 4 610 mm x 1 22 m and 4 x 4 1 22 m x 1 22 m boards in standard thicknesses of 3. Uê ià þ õ à ê tapered perlite roof insulation should be stored dry and be protected from the elements. 2 2 and 3 19 mm 25 mm 38 mm 51 mm and 76 2 mm. In recover applications all wet areas of the old roof must be removed.

It is ideal for use under concrete slabs in chimneys and in high temperature applications such as pizza ovens and rocket stoves. Energyguard perlite tapered roof insulation is factory fabricated from energyguard perlite rigid perlite insulation board. All loose and protruding gravel must also be removed.

Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof. Excellent for transitioning from membrane to nailer or transitioning from tapered fesco tapered enrgy 3 or tapered fesco foam panels to the roof level to help promote positive drainage. Field tapered perlitic insulation board systems consist of multiple layers of square edged perlite boards that are tapered by cutting or grinding in the field. Once properly loaded at the lê ã ìi ê ài ûiê v vì àþê üà ãê ê v ûià ê with a breathable tarp.

Combined with resistance to water absorption sproule wr 1200 perlite effectively minimizes corrosion to outer pipe surfaces and equipment while providing excellent thermal insulation. Perlite insulation is an inorganic product that does not support combustion or rot nor does it provide a habitat for rodents. Tapered roof insulation systems are supplied in 2 x 4 0 6 m x 1 2 m or 4 x 4 1 2 m x 1 2 m boards custom cut and tapered to 1 16 1 2 1 8 1 1 4 2 and 1 2 4 per foot 5 2 10 4 20 8 or 41 6mm m slope depending on the need.
