IN TUNE WITH THE DEMANDS OF MODERN CONSTRUCTION

Unrivalled Versatility

As a roofing material polymer modified mastic asphalt is ideal for use as a waterproof covering over flat, sloped or curved surfaces and can be worked round pipes, roof lights and other projections. It can be laid on most types of rigid substructure such as concrete, pre-cast concrete deck units, timber boarding, metal decking and other proprietary decking units.

Thermal insulation materials can easily be laid as part of a Permaphalt specification to give the required U value. Treatments applied to Permaphalt can provide a surface suitable for traffic, increase solar reflectivity and provide a decorative finish.

Unrivalled Performance

Mastic asphalt has kept pace with today’s technology. Permaphalt’s advanced polymer formulation makes it the perfect choice for any roofing application. It offers low temperature flexibility, high temperature stability and long term durability.

A roofing system which includes Permaphalt achieves the highest fire performance ratings, improves acoustic performance and offers proven performance when laid over modern thermal insulation materials.

Many Design Possibilities

Permaphalt offers the architect more scope for design opportunities. Because it is totally seamless, Permaphalt is ideal for roof gardens, paved areas, leisure complexes – any situation where general aesthetics have to be combined with good waterproofing. Furthermore it is an exceptionally versatile material which can be moulded to form any shape or contour.
