GuardMaster 250 Black Friday Sale! At less than 5lbs, GuardMaster’s light weight makes it easy to transport and store. The use of a liquid applied water resistive barrier is superior to paper based water-resistive barriers because there are no issues with rips or tears in the paper thus providing a continuous layer of moisture protection. They can be either air barriers or “breathable” vapor permeable barriers depending on the needs of the project. Sheathing is placed on the exterior side of the studs and insulation and used as a structural element for lateral support as well as a backing to the weather resistive barrier and cladding. Fire Resistant, non-permeable, synthetic polymer. 2 and flashings per section 1405. Finish coat, typically including colorfast, crack-resistant acrylic. The old guy in me intuitively believes that the shape of the curve describing the traditional building papers (WRB's) is "good. Felt is an excellent weather barrier and is even better at allowing vapor to escape. An optional water-resistive barrier (WRB) that covers the substrate A drainage plane between the WRB and the insulation board that is most commonly achieved with vertical ribbons of adhesive applied over the WRB Insulation board typically made of expanded polystyrene (EPS) which is secured with an adhesive or mechanically to the substrate. Sentry Stucco Plus is an extremely sophisticated Portland cement-based exterior wall system. 3, as applicable, and under the IBC where installed in Climate Zone 1A, 2A, or 3A, a ventilated air space shall be provided between the stucco and water-resistive barrier.
