The special SYNTAN® replaces the conventional sanded surface making the product lighter, easier to transport and handle on site and enhances vapour management performance and heat transfer efficiency.
Distinctive Stripes Eliminate Blistering
Resins are profiled in a distinctive stripe pattern on the underside of the underlay membrane. Between the stripes is the red SYNTAN® coating. When the underlay membrane is bonded to the insulation, resin-free channels are formed conducting water vapour to the outside under its own pressure. This eliminates the danger of vapour induced blistering that can cause premature failure of the waterproofing in conventional systems.
