HOW DOES IT WORK?
Create a usable outdoor area all year round with 5 Star Decking’s innovative underdecking solution
A waterproof ceiling system designed to keep the space beneath your deck completely dry, stylish, and functional.
Water passes through your decking boards naturally. Our engineered panels catch it, channel it to the gutter, and create a smooth, waterproof ceiling below. It’s simple, clean, effective — and instantly transforms the space.
