Build on Ventgrid for the Best Rainscreen System

An exterior wall system should incorporate Ventgrid12™, created in Chester, Nova Scotia, Canada, to offer proper air space, ensuring water can escape instead of collecting behind the siding. Count on us for reliable rainscreen cladding. This helps prevent water damage and mold/mildew formation.

Rainscreen application

As our climates continue to change, the storms that we encounter may get worse. More than ever, exterior walls will need to be designed to handle higher amounts of wind and driven rain and keep the water from entering the interior space.

Rainscreen wall assembly construction is the proven way to deal with the water that penetrates the cladding. Most cladding products will allow a certain amount of water to pass through. The challenge is to ensure the water can then escape instead of collecting behind the siding. If not, there is a substantial risk of water finding its way into the interior space or creating damaging mold and rot. A capillary break is needed in the form of air space between the backside of the cladding and the sheathing paper. The thickness of the air space depends on local codes, but 10mm(3/8”) is considered adequate for most regions.

Ventgrid12™ is simply the very best method to create a proper air gap in a rain-screen wall assembly. It is rot and mold resistant, rigid, non-compressible, and easy to install.


Building a ventilation layer with rugged Ventgrid12™ panels between the shingles/shakes and roof sheathing will increase the roofing materials' longevity and help maintain an even temperature in the building's interior living space.

For centuries cedar wood shingles and shakes have been considered the preferred choice for sloped roofs in virtually all climatic conditions. Durable, long-lasting, and aesthetically pleasing, natural cedar is always the crowning feature of high-quality construction.

However, today's climate conditions challenge even the best building products, and roof construction is certainly not exempt. It is a well-known fact that the sun's intensity has increased dramatically in recent years, adversely affecting anything left exposed. As a result, unprecedented heat build-up commonly occurs between the shingles and the roof sheathing causing degradation in splitting, cracking, curling, warping, and cupping, resulting in significant openings for water pour-ins. 

In addition to the solar damage, weather, including strong winds and driving heavier rains, can ultimately overwhelm the roof assembly leading to catastrophic failures. A secondary benefit is the drainage plane formed by installing Ventgrid12™ behind the roofing materials, thereby creating another layer of protection for the structure itself.
