High Tech Roof Underlayments From Cosella-Dörken

Four roof underlayments representing the latest advances in roofing technology from Europe will be introduced by Cosella-Dörken on Feb. 14, 2008 at the International Builders Show in Orlando, Fla. The new product launch marks the Beamsville, Ont., building materials manufacturer’s expansion into the roofing category in North America.

The DELTA® brand roof underlayments are not only said to keep weather out, but reduce energy consumption, reflect up to 50 per cent of radiant heat, help rid the home of excess moisture, hold their own in a hurricane and can double the life of the roof.

In 1965, the manufacturer’s parent company – Dörken – was among the first to produce a synthetic roof underlayment. Now considered a leader in this product category, it has developed and perfected underlayments with new performance characteristics, which will be sold in North American markets as DELTA®-MAXX TITAL, DELTA®-FOXX, DELTA®-VENT S and DELTA®-ROOF.

“Since U.S. and Canadian housing markets are swinging toward environmental products, the timing is right for new underlayments to replace old technology such as roofing felt,” said Marcus Jablonka, vice president of research and development and production. “Our products are cheap insurance against mold and water damage, and reduce energy and replacement costs for long-term savings that far outweigh their original cost.”

DELTA®-MASS TITAN roof underlayment has all-new energy-saving and moisture-handling characteristics. Its shiny silver titanium coating reflects up to 50 per cent of radiant energy to keep homes cooler in summer. A self-adhesive border speeds installation and acts like a zipper to lock weather out and keep home temperatures comfortable. By lowering air-exchange rates, TITAN reduces heat-energy consumption to nine per cent.

MAXX TITAN is watertight and exceptionally vapour permeable. It is the only underlay equipped with a bottom layer to absorb excess moisture. The sponge-like layer safeguards wood roof rafters and sheathing by soaking up excess condensation or water, for release later through evaporation.

The better-insulated, more airtight homes of today need roofing materials that can handle moisture that comes from both inside and out. DELTA®-FOXX and DELTA®-VENT S are multi-layered underlayments used on fully-insulated pitched roofs. Although their outer surface is impermeable to wind and rain, they are highly permeable to water vapour that originates from inside and have a moisture management layer to facilitate its evaporation. Compared to standard, impermeable membranes, these high-end underlayments can significantly extend the life of this type of roof.

DELTA®-ROOF is the new solution developed for ventilated roofs with conventional asphalt shingles. This non-permeable roof underlayment provides four layers of top protection against any type of weather. Reinforced with a tear-proof grid structure, it is the ideal choice for extreme weather situations, or wherever roofs can’t be finished on a same-day basis and will be exposed to wind.

All underlayments are exceptionally tough, highly resistant to UV, abrasion and tearing, non-slip on both sides even in wet conditions, lightweight and easy to handle and apply. Unlike standard roofing felt or paper, they will not distort or buckle if wet by rain. DELTA roof underlayments come in rolls of 164- by 4.92-feet (50- by 1.5-metres).
