Product Description

The Instalay Q25 high-grab 2.5mm underlay has changed the way floors are installed, removing the need for any glues or nails and has significantly reduced the mess and labour times linked with flooring installations.

Ideal for:

  • Solid/engineered wood flooring (tongue & groove)
  • Laminate flooring (click joint)
  • Parquet flooring (no joint system)
  • Luxury vinyl tiles (dryback)
  • Woven vinyl tiles (dryback)
  • Porcelain tiles

It delivers excellent acoustic insulation, outstanding comfort and stability, high durability, with anti-microbial and anti-allergy properties plus its low tog rating makes it ideal for underfloor heating systems. The Q25 high-grab has the benefit of being supported internally by recycled vulcanised rubber crumb granules; when the granules are compressed the granules provide an excellent cushioning performance, once the pressure is released the granules immediately return to their original form.
