ParexLahabra Expands Application Usage of Water-Resistive Barrier Products

  Subscribe to FREE newsletter  Aug 21, 2009

ParexLahabra, the parent company of leading building material brands; Parex, LaHabra, El Rey Stucco, Teifs, Mer-Krete and Mer-Ko, has announced the expanded usage of their Water-resistive Barrier (WRB) line of products.

Previously, ParexLahabra WRB products were limited to use under their EIFS and stucco assemblies only with limited substrates. After successfully conducting multiple tests, the use for these products has been approved for use under other exterior claddings and opening the range of substrates that can be used. "This is a major leap forward for our business,” said Quenton Roehricht Brand Manager. “The significant advancement allows ParexLahabra to market its WRB and air barrier products to a larger range of customers. The liquid, water-resistive barrier, and air barrier markets are seeing phenomenal growth right now and we are excited to participate.”

“With the advancement of substrates and the excellent quality of raw materials used, in ParexLahabra products, we are excited to give warranties for the use of ParexLahabra Water-resistive Barriers under other fa├žades and over many different substrates e.g. plywood, OSB, Densglass Gold™, etc.”, said Robert Dickson, Technical Director for ParexLahabra.

ParexLahabra liquid applied water-resistive barrier products are far superior to sheet based products. There is no risk of ripping or tearing, as with paper products, and liquid water-resistive barrier products are applied in a continuous layer. “These products may be used on a number of substrates including OSB,” Roehricht commented. "This is a significant shift from ParexLahabra’s prior position and a benefit for the applicator. We believe we have the best liquid applied water-resistive and air barrier products on the market".

ParexLahabra’s Water-resistive Barrier products are available in 5 gallon pails.
