Underlay for wood and laminate floors that adds thermal insulation and reduces impact noise. Homeowners fitting new laminate will notice a warmer, firmer surface underfoot with fewer hollow sounds. Is B2C XPS Underlay Insulation the practical choice for straightforward DIY installs and small-room projects?
⚡ At a Glance
- • Underfoot Comfort: Provides a warmer, firmer feel while smoothing minor hollow spots beneath laminate.
- • Best for: DIY homeowners and fitters installing wood or laminate flooring seeking insulation and quieter rooms.
- • Not ideal for: Installations that require substantial subfloor levelling or structural replacement work.
Five millimetre boards come in packs covering 5m2 and generally reduce noise by about 20 dB. Each pack contains ten boards sized 1000mm by 500mm and has a 2 Tog thermal rating.
Warmer rooms - with a 2 Tog thermal rating
The 5mm board thickness delivers a measured 2 Tog rating, limiting heat loss through the floor. The board format helps retain warmth close to the finished surface.
Reduced heat loss improves comfort in cooler rooms, so floors feel warmer underfoot and heating runs more efficiently.
Quieter floors - thanks to approximately 20 dB sound reduction
Acoustic dampening is achieved through the board construction, which lowers impact and airborne noise by around 20 decibels. The format reduces hollow-sounding areas beneath laminate or wood boards.
Footsteps and light impact noises become noticeably quieter, improving privacy between rooms and reducing hollow flooring sounds.
Stable, easier finishes - with supportive board format
Boards level minor surface imperfections and help brace board joints, while the non-absorbing, mould resistant composition resists damp-related issues. The lightweight format is straightforward to trim and position.
A smoother, more stable laying surface makes alignment simpler and gives a firmer feel underfoot, speeding up typical DIY installations.
