Is the Dual Overlay fixed to the subfloor?


The Warmup® Dual Overlay is a floating subfloor – it is not fixed to the floor below.

The system includes a 3mm  base board and a 4mm top board with contact adhesive, which bonds them together to make one solid subfloor,

It provides a smooth and seamless subfloor making it suitable for soft and resilient floor coverings such as carpet, vinyl and linoleum. The combined thickness of the Underlay and Dual Overlay is 13mm.
