Self-Adhesive and Perfect for Soundproofing and Underfloor Heating under Wood (click joint), Laminate (click joint) and Vinyl (click joint).

Instalay Q30 Low-Grab is a 3mm peel and stick acoustic underlay can be laid under:

  • Luxury vinyl (click joint)
  • Engineered wood (click joint)
  • Laminate installations (click joint)
  • Carpet tiles

It delivers excellent acoustic insulation, outstanding comfort and stability, high durability, with anti-microbial and anti-allergy properties plus its low tog makes it ideal for use with underfloor heating systems. Instalay is also environmentally friendly being made from recycled rubber from car tyres – and being recylable itself.


It’s recommended that on all concrete sub-floor applications a damp-proof membrane is applied prior to installation, because some floors are susceptible to water damage (wood, laminate or vinyl). The joints should overlap by a minimum of 150mm and should be taped and sealed with a waterproof adhesive tape. To expel the water vapour above the finished floor the damp-proof membrane should be allowed to extend up the perimeter of the wall by 50mm, the membrane can be later trimmed level with the surface of the finished floor.

Instalay Q30 Low-Grab is designed to not require glue, nails or grippers and to be quick to fit, easy to work with – cutting installation time by half.
