Protected membrane roof systems.
Protected membrane roof system.
Heat welded seams provide superior strength.
By overlaying the membrane with opaque ballast and thermal insulation the membrane is protected against accelerated oxidation evaporation of volatile oils ultraviolet degradation of organic materials such as bitumen thermal movement expansion and contraction blistering ridging and stress concentration over insulation joints.
The insulation is protected from environmental extremes but is exposed to moisture.
Also known as a protected membrane or upside down roof inverted roofs employ insulation which can resist water absorption provide excellent thermal performance be unaffected by freeze and thaw cycles withstand surface traffic and be protected from uv and mechanical damage among others.
Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system.
Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price.

Epdm roofing has a longer lifespan than tpo while the pricing between the two membrane roofing systems is comparable epdm roofs generally have a longer lifespan.
The natural water resistance of.
This is done as the membrane is being installed so that a good bond is attained between them.
Sika worldwide what is your region and language.
Protected roof membrane assembly prma popular in green roofing systems the protected roof membrane assembly prma places the insulation layer above the waterproofing membrane an inversion of traditional roofing systems.
Extruded polystyrene xps is the most suitable type.
By simply reversing the insulation and the waterproofing membrane insulation on top of the membrane rather than beneath the cause of many roofing problems can be eliminated.
Epdm roofs are easy to repair and restore one of the most common roof types on the market epdm roofs are a natural fit for our highly effective conklin roof replacement systems.
Protected membrane roof pmr in a protected membrane roof also known as an inverted roof membrane assembly irma the insulation is installed on top of the membrane.
This approach is commonly referred to as a insulated roof membrane assembly irma or protected membrane roof pmr.
