epiROOF EPDM Rubber
A high quality EPDM rubber membrane to waterproof roofs and decks.
epiROOF® is a high quality EPDM rubber membrane used to provide waterproofing protection for a variety of roofing and exterior deck applications.
The epiROOF® system is a fully bonded rubber membrane applied over concrete, steel, fibre cement boards or construction plywood substrates. epiROOF® has been independently appraised as an Accepted Solution under E2/AS1 and as an Alternative Solution under the NZBC.
EPDM membranes have over 40 years of extensive use internationally. EPDM is regarded as one of the most durable membranes available. Furthermore, EPDM typically demonstrates a much higher elongation after ageing than other membranes. This is particularly important when working on timber substrates which are prone to movement.
History of Use
In addition to the benefits of being an EPDM membrane, epiROOF® has extensive history of use. First installed in 1965, literally hundreds of millions of square metres have been installed since that time. epiROOF® has been used in some of the most demanding projects including the Toyota manufacturing facilities in Japan.
The two-part low solvent epiBOND® adhesive gives a high performance bond. epiBOND® is used to adhere the epiROOF® to the substrate and undetake all detailing work. No special seam primers or other solvents are required.
epiTAPE® is used in all lap joints to ensure an intimate seal. epiTAPE® is a non volcanised rubber, that vulcanises over time to produce an almost indestructible water tight seal.
When fixed according to specification, the epiROOF® system will meet the NZBC B2.3.1 (b) requirements of 15 year durability. epiROOF® meets the ASTM D6134 standard required by the Department of Building & Housing E2/AS1 Acceptable Solution for NZ3604.
The durability opinion given by BRANZ states that when subjected to normal conditions of environment and use, epiROOF® is expected to have a service life of at least 20 years. Case histories of the epiROOF® systems plus extensive thermal ageing and ozone testing indicates the epiROOF® system is durable for in excess of 40 years.
