FineFloor TechniBoard is a lightweight XPS underlay panel designed for floating laminate and floating engineered wood flooring. It helps smooth out uneven areas to create a more stable base, improves insulation to make rooms feel warmer underfoot, and reduces footfall noise to make spaces feel quieter.
Supplied as 5mm panels, it is ideal where you want strong thermal performance, particularly in colder rooms. Each pack covers 6m² and includes 10 panels, with each panel measuring 1200mm x 500mm, making it easy to plan coverage for room sizes.
This underlay is intended for floating floor installations only. It is not recommended for use with underfloor heating. Lay panels on a clean, level subfloor, butt joints tightly together, and follow the flooring manufacturer’s fitting guidance for the full floor build-up.
