Only the best under your feet!
Insulation underlay with the gecko effect

Thinking of installing laminate, parquet, cork, vinyl or designer flooring? Then you should also consider investing in some good floor insulation. A good insulation underlay is essential for effective soundproofing and is the best way of avoiding the annoyance of noise echoing around your rooms and downstairs neighbours complaining about the sound of footsteps.

If it was easy then anyone could do it...

GREEN LIGNIN has been painstakingly crafted as an alternative to over-complex and clumsily designed underlays. The carefully chosen 1.8 mm thickness of the material makes installation far, far simpler. And the fact that GREEN LIGNIN is almost exactly the same thickness as standard commercially available transition strips makes it easy to overcome differences in height between multiple areas of flooring.
