Self-welding material promises weatherproofing for HVAC pipes and ducting

Wraptec claimed to have a watertight bond and ability to stretch up to 50 per cent

Roofing products specialist Braas Monier has launched Wraptec, described as a ’universal cladding and jacketing material’ for weatherproofing HVAC pipes and ducting. Unlike self-adhesive tapes, the backing of the poly-isobutylene material self-welds to the facing on laps to create a watertight bond which lasts even in extreme weather conditions, the company says.

Because it doesnt require primers, adhesives sealants or heat activation, it is a fast and highly cost-effective means of preventing corrosion under insulation (CUI) at the duct pipe, the company says, offering exceptional UV resistance.

The Wraptec can be stretched by up to 50 per cent in either direction without loss of functionality and cut using scissors or shears, making it well suited for detailing and applications on irregular surfaces. Rolls are available in four sizes from 70 mm to 560 mm.
