Product Focus on Waterproofing/WRBs/Rainscreens
Synthetic breathable WRB
Intertape Polymer Group Inc.
NovaWrap Building Wrap is a 100-percent synthetic breathable weather resistant barrier for residential and commercial applications. It allows vapor and condensation to escape from wall cavities while protecting against air and moisture infiltration. The product is a non-woven polypropylene one-sided coated fabric. It does not absorb or retain water. It exhibits strong liquid holdout, as well as superior durability and tear resistance. It is compatible with nearly every type of sheathing, including plywood, OSB, gypsum and rigid foam. It also installs easily under brick, stone, EIFS, fiber cement board, wood, vinyl, metal and composites. It meets or exceeds applicable building codes for WRBs and complies with the new IECC energy codes as an energy barrier.
Rainscreen deflection system
Benjamin Obdyke Inc.
Home Slicker Rainscreen and Blockade Mortar Deflection System products provide a continuous space for drainage and drying, as well as a thermal break and pressure moderation, eliminating the threat of trapped moisture. The system allows moisture to quickly escape before it damages the sidewall materials, prevents damage from surfactants by separating the cladding from the water-resistive barrier and saves time and labor costs by eliminating the need for furring strips.
Pre-applied waterproofing system
Grace Construction Products
Preprufe Plus is an enhanced version of Preprufe that allows for faster installation
and stronger adhesion at the seam. The product forms an adhesive bond to the
concrete placed against it and thus does not rely on the earth outside of the building
(which could erode or fall away from the building over time) to confine or hold the
Preprufe membrane in place. The system has colored zip strips at the top and bottom of
the seam area on the edge of the roll. Once the zip strips are removed, a magnetic adhesive to adhesive bond is achieved at the seam that is stronger than with the standard product.
Rainscreen and ventilation mats
Stuc-O-Flex International Inc.
WaterWay Rainscreen Drainage Mats offers a Filter Fabric exceeding AC-38 Criteria for Water Resistive Barriers combined with a Perm Rating more than 240. The product consists of a nylon/polymer core of fused, entangled filaments in varying thicknesses from a nominal 1/4 to 3/4 inch, depending on desired cavity space and cladding selection. Certain profiles are available with a protective Moisture Resistive Filter Fabric bonded to one side or consider WaterWay Plus, a drainage mat incorporating a .45-inch/11-millimeter thick polymer matrix heat laminated to a breathable filter fabric on one side and Typar code compliant (NER-660, CCMC-12892R) weather resistive barrier on the other side.
