Polyisocyanurate rigid foam board insulation is shown installed in a tapered design over a flat roof.
Perlite tapered roof insulation.
Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof.
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.
It is ideal for use under concrete slabs in chimneys and in high temperature applications such as pizza ovens and rocket stoves.
Tapered fesco edge strips.
Perlite roof insulation its insulating efficiency.
Uê ià þ õ à ê tapered perlite roof insulation should be stored dry and be protected from the elements.
Energyguard perlite roof insulation is designed to be used directly over structural roof decks.
It is also widely used as a separation board over existing roofs in recover installations.
In recover applications all wet areas of the old roof must be removed.
Johns manville s solution is an expanded perlite product with a built in corrosion inhibitor.
All loose and protruding gravel must also be removed.
2 2 and 3 19 mm 25 mm 38 mm 51 mm and 76 2 mm.
Some tapered insulation is formed with a slope and only needs to be pieced together during the installation process.
Perlite insulation is an inorganic product that does not support combustion or rot nor does it provide a habitat for rodents.
The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes.
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.
Energyguard perlite tapered roof insulation is factory fabricated from energyguard perlite rigid perlite insulation board.
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.
Combined with resistance to water absorption sproule wr 1200 perlite effectively minimizes corrosion to outer pipe surfaces and equipment while providing excellent thermal insulation.
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.
Ià þ õ à ê tapered perlite roof insulation is a non structural non load bearing material.
Dual purpose structural deck and insulating planks.
