Protected Membrane Roof Design

The protected membrane roof pmr has represented the best in flat roof technology since it was developed in 1970.

Protected membrane roof design.

Ballast options and flexibility. A pmr incorporates an upside down approach to insulating the roof. Protected membrane roofing insulation technology has evolved over the decades and some types like rigid extruded polystyrene foam xps is highly water resistant. 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.

Protect provide a comprehensive range of construction membranes roofing membranes and roofing accessories. The chief benefit of pmr roof design is that the covering protects the waterproofing membrane from thermal shock ultraviolet light and mechanical. The pmr concept was simple yet radical. Frequently rigid panels made of extruded polystyrene are used in pmr construction.

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. 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.

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.

Placing the insulation on top of the waterproof membrane. Membrane roofing is a roof system that creates a continuous watertight covering to protect the interior of a building. This insulation can be placed above the roof membrane protecting the membrane from elements while continuing to deliver thermal efficiency. In a protected membrane roof the mineral aggregate functions as ballast that keeps the insulation in place.

Membrane roofs are predominately used as a flat roofing system since they are watertight which is critical where water is not shed immediately. Protected membrane roof planning guide page 3 people make the difference hydrotech s sales representatives and staff work closely with design.
