Adding a drainage mat provides a means for air circulation and moisture control on the exterior of your home. By creating a pocket of air, the drainage mat creates a way for moisture buildup or wind-driven rain potentially trapped under panels to dry and evaporate faster. Adding them during a home remodel is a good way to add peace of mind knowing you have extra protection.
This exterior home accessory provides a layer of air that assists in moisture ventilation, improved home breathability and decreases the chance of leaks caused by trapped water. Studies by the NAHB (National Association of Home Builders) have shown that drainage mats, also known as “rain screens”, can increase a home’s energy efficiency as well.
A home remodel in areas that do not require a drainage mat or rain screens by code can use this accessory as an alternative to still add the peace of mind they offer. A drainage mat may not be necessary for installation of panels on top of concrete foundations or brick. Please check your local building code requirements to determine if a drainage mat is a necessary addition to your home remodel. Even if one is not required, we recommend using a drainage mat during an exterior home remodel for the added moisture protection, increased efficiency provided, and improved home breathability.
Our Gray drainage mat is made from recycled polypropylene and meets the Canadian Building Code requirements for drainage mats and rain screens. Not all States, regions, countries, townships, etc. require a drainage mat as an exterior home accessory. The Blue drainage mat is a nylon mesh with a larger coverage area than the Gray but a smaller thickness. This exterior home accessory will not meet Canadian Building Code requirements.
Please remember to check with your local, regional and/or national building codes to ensure proper construction and correct materials required by law.
