What is InsideOut?

There are many under deck drainage systems on the market, but few that offer the strength of the InsideOut Underdeck system. Our innovative underdecking product is unlike the rest because it is made from a highly durable, titanium-stabilized aluminum alloy that is far stronger than the vinyl that most other under deck ceilings are made from. The superior strength of our system allows it to withstand up to 20 pounds per square foot without sagging, breaking, cracking, or bending. That means it can easily support the weight of ceiling fans, lighting fixtures, and even as much as three feet of freshly fallen snow. Even extreme cold or heat won’t affect our underdecking, because it is designed to resist seasonal expansion and contraction, a situation that often causes warping and even seam separation in vinyl systems.

In addition to the outstanding durability of our system, it’s able to effectively drain away incredible amounts of rainfall. Our system’s patented, locking grid and panel structure allows our system to drain as much as 15 inches of rainfall per hour when installed by a professional dealer. So, you’ll never have to let a rainy day keep you from enjoying the outdoors.

InsideOut underdecking is even available in a wide array of matte colors and woodgrain laminates, so you can choose a finish that perfectly suits your tastes and helps to extend the beauty of your home to your under deck living space.
