Perlite Tapered Roof Insulation

Dual purpose structural deck and insulating planks.

Perlite tapered roof insulation.

All loose and protruding gravel must also be removed. Once properly loaded at the lê ã ìi ê ài ûiê v vì àþê üà ãê ê v ûià ê with a breathable tarp. Factory tapered insulation board systems are the ones most commonly used because they are inexpensive and easy to use. In recover applications all wet areas of the old roof must be removed.

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. Tapered fesco edge strips. Perlite insulation is an inorganic product that does not support combustion or rot nor does it provide a habitat for rodents. Fescant plus cant strips.

Uê ià þ õ à ê tapered perlite roof insulation should be stored dry and be protected from the elements. 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. Ià þ õ à ê tapered perlite roof insulation is a non structural non load bearing material.

The surface is treated to reduce bitumen absorption ensuring proper adhesion of roof membranes. 2 2 and 3 19 mm 25 mm 38 mm 51 mm and 76 2 mm. 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. Polyisocyanurate rigid foam board insulation is shown installed in a tapered design over a flat roof.

When correctly installed tapered insulation helps eliminate problems due to ponding water and can extend the longevity of your low slope roofing system. 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 roof insulation its insulating efficiency. It is also widely used as a separation board over existing roofs in recover installations.

It is ideal for use under concrete slabs in chimneys and in high temperature applications such as pizza ovens and rocket stoves. Johns manville s solution is an expanded perlite product with a built in corrosion inhibitor. 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.
