Best Underlay

For Carpet

Does your choice really matter, and what is the best underlay for carpet?

Our performance-based testing program assesses the 3 key performance indicators of a quality underlay. All testing is conducted in a controlled environment by independent laboratories in New Zealand and Abroad.

Test Number 1

To demonstrate what the best underlay for carpet is, we conducted a Hexapod Tumbler Test which is used by the ACCS to assess anticipated short-term and long-term appearance change in the texture and colour of carpets. Their assessments of texture and colour change are made at 1500 cycles (simulated 9-12 months in service) and 8000 cycles (3-4 years in service equivalent).

Nothing more to say really

Standard Premium Underlay

Other carpet underlay

Although far better than having no underlay under your carpet, signs of wear are evident with standard underlay after testing. With a minimum thickness loss of 9% and a max of 11%, the carpet fibres, like the underlay flatten.
