WaterWay Drainage Mats in Roofing Applications
Galvanized metal roofing (zinc coated) is common in commercial buildings and especially susceptible to corrosion. In any climate, moisture can build up under the roof and cause damage to the structure. Thankfully, when you incorporate our WaterWay Rainscreen underlayment mats as a spacer between the metal and roof sheathing, you create a passage for moisture drainage and greatly reduce the risk or water accumulation that would lead to corrosion and additional moisture damage. In cold weather, a cold roof surface is desirable to prevent the build-up of ice and the problems associated with ice dam backup. WaterWay mats create a thermal break and ventilation layer in the roof where the conduction of heat would normally occur. This characteristic reduces the potential for ice dams. Managing your walls and roofs can sound difficult, but with Stuc-O-Flex International and our quality drainage mats, keeping water out can be easy.
"Need a vent layer in commercial roofing?"
For many designers the need for a ventilation layer between the roofing shingle or membrane and the insulation has become a standard technique to ensure that moisture does not build up beneath the sheathing. Furring is an expensive way of spacing the insulation from the sheathing and limits ventilation to one direction. This system can now be replaced by a single layer of WaterWay Rainscreen Mat designed to reduce roof top temperatures while providing maximum insulation efficiency. The mat is rigid enough to support the full weight of the roof and its open structure allows for multi-directional ventilation. For the contractor, the installation of this lightweight product is easy and quick. If you're ready to keep water out of your space, you'll want Stuc-O-Flex.

"Easier to work with and is a cost effective alternative" - Espina Stone Co. Center for the Arts at Virginia Tech - Fairfax, Virginia
This review is for: WaterWay Rainscreen
Prior to using WaterWay Rainscreen, we were using a foundation material that was a hard plastic dimple board with a filter fabric over the top of it, it was much more rigid and difficult to work with. This rainscreen serves the same function, is easier to work with and is a cost effective alternative.

"Recommend WaterWay Rainscreen" - Lochwood-Lozier Custom Homes, Washington
This review is for: WaterWay Rainscreen
"Whether using traditional stucco or EIFS, it's important to use a good drainage system, I recommend the WaterWay Rainscreen Drainage Mats, with a 7/8-inch thick traditional cement based core, and the Stuc-O-Flex finish. This prevents moisture-related problems, and allows the system to flex and move without cracking."www.lochwoodlozier.com
