The weber.therm XM External Wall Insulation (EWI) system holds NSAI Agrément (Irish Agrément Board) Certification and is fully compliant with current Building Regulations.  Recently, additional products and applications have been added to this Certification which will have substantial impact on the Irish construction market.

The latest amendment to the IAB Certification relates to below DPC where heavy duty polystyrene board, normally between 30/50mm, will be used with a 6mm weber.rend LAC base coat render, incorporating  fibreglass meshcloth, with a finish coat of either weber.sil P, a high performance water-based silicone resin emulsion paint, or weber.plast P, a silicone-enhanced breathable and protective coating, which are both suitable for masonry substrates. This refinement will improve performance, speed installation and significantly reduce cost.

The use of PIR insulation board as an integral part of the weber.therm XM EWI system is expanding fast alongside the standard white EPS, mineral wool and phenolic insulation materials. This comprehensive list of integrated materials within the Certification for weber.therm XM EWI offers specifiers the broadest scope in meeting subsidiary design requirements whilst achieving the high performance results of the core weber.therm XM EWI system.

Perfect for the retrofit business, the weber.rend RB EWI system achieves a natural brick appearance using two coats of render to create a ‘mortar joint’ and a brick-effect coat while providing all the attributes of the weber.therm EWI system, and is now fully IAB Certificated.

weber.therm XP EWI is a new generation, and well proven, insulated render system that features specially formulated through-colour mineral one-coat render with a variety of texture finishes. This one-coat application process significantly reduces application time and associated on-site costs. The weber.therm XP EWI system will receive full IAB Certification later this year.
