Ease Rainscreen Design and Installation

VaproShield introduces two accessories to its product line: VaproShims and VaproMat. Designed to tackle the costly and time-consuming installation process frequently associated with rainscreen design, VaproShield’s accessories provide superior building envelope ventilation at a minimal cost to contractors and consumers.

While each of the new accessories offers versatile features, VaproShims and VaproMat, in particular, were uniquely tailored to different project types. VaproShims are used under horizontal cladding attachment components to create a 1/4-inch vertical rainscreen drainage plane. This simple design adds drying capacity to the building envelope without adding wall thickness, making VaproShims ideal for projects using traditional cladding types like metal panels, composite panels and wood siding. VaproShim’s neoprene/EPDM composition seals fastener penetrations and is tested to the ASTM E331 standard against water penetration.

By comparison, VaproMat, a lightweight, polypropylene drainage matrix with an integrated filter fabric, is designed to create a positive drainage cavity behind cememtitious claddings that traditionally do not incorporate a rainscreen cavity. Ideal for use with stucco or cultured stone, VaproMat comes in two depths, 3- and 7-millimeter, and is designed to keep the drainage cavity unobstructed during the lath and plaster installation for rapid drying of the building envelope and cementitous materials.
