Frequently Asked Questions About Cloud 9 Underlay
Direct answers from Paul to help you make informed decisions about your flooring project.
Why is Cloud 9 PU underlay better than traditional rubber underlay?
PU foam is made from recycled materials, offers superior thermal insulation, is 70% lighter to handle, and will not crumble or rot into black dust over time like sponge rubber.
Can I reuse my old underlay when fitting new carpet?
In 95% of cases, no. Crushed underlay loses its rebound resilience, voids carpet manufacturer wear warranties, and causes early carpet wear.
Which Cloud 9 underlay is best for flat leasehold acoustic requirements?
Cloud 9 Cumulus 11mm delivers an outstanding 43dB impact sound reduction, helping flat owners meet strict leasehold acoustic covenants.
Can Cloud 9 11mm be used on stairs?
11mm can feel spongy and roll over stair nosings; we recommend high-density Cloud 9 Connoisseur 8mm/10mm or Bliss 9mm for stairs.
