Perlite Tapered Roof Insulation

Johns manville s solution is an expanded perlite product with a built in corrosion inhibitor.

Perlite tapered roof insulation.

Combined with resistance to water absorption sproule wr 1200 perlite effectively minimizes corrosion to outer pipe surfaces and equipment while providing excellent thermal insulation. It is also widely used as a separation board over existing roofs in recover installations. Perlite insulation is an inorganic product that does not support combustion or rot nor does it provide a habitat for rodents. Energyguard perlite roof insulation is designed to be used directly over structural roof decks.

Ià þ õ à ê tapered perlite roof insulation is a non structural non load bearing material. 2 2 and 3 19 mm 25 mm 38 mm 51 mm and 76 2 mm. Uê ià þ õ à ê tapered perlite roof insulation should be stored dry and be protected from the elements. Manufactured from jm cant board a high density laminated perlite board that provides excellent transition from the deck to the wall of the roof.

In recover applications all wet areas of the old roof must be removed. Factory tapered insulation board systems are the ones most commonly used because they are inexpensive and easy to use. The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. Some tapered insulation is formed with a slope and only needs to be pieced together during the installation process.

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. All loose and protruding gravel must also be removed. Fescant plus cant strips. Polyisocyanurate rigid foam board insulation is shown installed in a tapered design over a flat roof.

Energyguard perlite tapered roof insulation is factory fabricated from energyguard perlite rigid perlite insulation board. It is ideal for use under concrete slabs in chimneys and in high temperature applications such as pizza ovens and rocket stoves. Dual purpose structural deck and insulating planks.
