Protected membrane roof design.
It is applied dry on to the surface of the insulation or on top of a filter fabric that is installed on top of the insulation first.
This insulation can be placed above the roof membrane protecting the membrane from elements while continuing to deliver thermal efficiency.
The protected membrane roof pmr has represented the best in flat roof technology since it was developed in 1970.
One of the advantages of using mm6125 in a protected membrane roof assembly pmr is that once the membrane is installed owners and designers can take advantage of various ballast options gravel pavers and garden roof to suit a specific project s needs.
Frequently rigid panels made of extruded polystyrene are used in pmr construction.
Protect provide a comprehensive range of construction membranes roofing membranes and roofing accessories.
Modern green roofs are a type of protected membrane roof.
Ballast options and flexibility.
Membrane roofing is a roof system that creates a continuous watertight covering to protect the interior of a building.

While experts believed this design would improve the membrane s.
This development has been made possible by the creation of waterproofing membrane materials that are tolerant of supporting a load and the creation of thermal insulation that is not easily damaged by water.
The construction range includes vapour permeable wall membranes including enhanced thermal performance solutions vapour control and air barriers also with enhanced thermal performance solutions and a range of sealing tapes and other accessories to provide a one stop shop for all requirements.
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.
In a protected membrane roof the mineral aggregate functions as ballast that keeps the insulation in place.
The pmr concept was simple yet radical.
Membrane roofs are predominately used as a flat roofing system since they are watertight which is critical where water is not shed immediately.
A pmr incorporates an upside down approach to insulating the roof.
