Top 10 Reasons to Choose EPDM
RPA's EPDM membranes offer an optimal solution for nearly any low-slope roofing situation. EPDM is a durable material that has more than 50 years of proven, in-field performance. With significant physical property advantages, warming benefits in northern climates, and innovations in product technologies, EPDM is still defining the standard in the commercial roofing market. Below are the top 10 reasons to consider EPDM on your next roofing project.
Time Tested
Carlisle EPDM rubber membranes have been in service globally for the last 60 years. Our South African markets have only just adapted EPDM as the preferred climate approved waterproofing system for the last 15 years proving that the system is well adapted and here to stay.
Superior Weathering Resistance
Carlisle EPDM rubber membranes is a vulcanised rubber allowing it to withstand South Africa’s high UV index without it needing special lead protective coatings or maintenance for 20 years guaranteed.
Thickness
Carlisle EPDM rubber membranes have been in service globally for the last 60 years. Our South African markets have only just adapted EPDM as the preferred climate approved waterproofing system for the last 15 years proving that the system is well adapted and here to stay.
Superior Hail Resistance
Numerous studies and real-world experience confirm that EPDM’s 465% elongation (ASTM D412) and weathering resistance result in superior hail damage resistance and UL2218 Class 4 rating.
Energy Efficient
Carlisle EPDM rubber membranes are only available in the colour black solely based on the South Africans temperature zone classification. Our region has an average yearly temperature of 21°C and lower where heating costs are higher than cooling costs. Carlisle EPDM Rubber Membranes also exhibit an insulation “R” value helping industry professional achieve energy requirements.
Environmentally Efficient and Safe
EPDM waterproofing stability, safety and sustainability EPDM dark colour is specifically chosen for South Africans warm climate averaging at 21°C assisting with heating requirements and has a certified “R” value for insulation calculations. Its pond approved accreditation allows for any sloped roof to be wrapped with EPDM due to its impermeable stability. Carlisle EPDM rubber membrane systems require no maintenance or coatings to retain their 20-year maintenance free warranty. All we require is a flat surface.
Stable
Carlisle EPDM Rubber membranes are vulcanised allowing them to resist various forms of attacks from chemical acids to environment pollutants and UV rays making it one of the most stable materials in the market.
Condensation
The solar thermal benefits of black Carlisle EPDM also help to reduce potential condensation issues of various types of insulation products. Undetected condensation in a roofing assembly can negatively affect the performance of paper insulation facers, weakening the bond between insulation and adhesive, and can have a detrimental effect on the insulation’s R-value, resulting in reduced thermal efficiency.
Large Panels = Reduced Seams
Carlisle EPDM Rubber Membranes are available in large widths up to 9m and lengths of 30m long drastically deducing seams joins and minimising potential failure points.
Fewer Seams
Seam positions and lengths are site specific and are minimised with experienced optimal utilisation of membranes to specific detailed areas. Seams are chemically formed and require no heat or external energy that can compromise seam quality and integrity reducing application error.
