OneDek®
OneDek® Insulated Roof Deck System is a superior alternative to traditional multi-layer, low slope roofing systems. OneDek® insulated roof deck system includes just two components to complete the roof, an insulated roof deck panel and a PVC or TPO membrane. OneDek® simplifies the design, procurement and installation of a low slope roof system by eliminating traditional components such as steel deck, vapor barrier, multiple layers of board insulation, and cover boards.

Features / Benefits
Higher Performance
- Two components vs up to seven components in traditional systems
- Higher R-value per inch of insulation
- Superior resistance to transverse load
- Durable steel surface that supports foot traffic
- Steel facing is impermeable to air and water
- Will not absorb moisture during or after installation
Single Source
- One source for all components of the roof assembly including the roof decking, air, water & thermal barriers
Faster Installation
- Fewer components and fastening requirments reduces the complexity and time to install the roof assembly
Sustainability
