Frequently Asked Questions
Common questions about marine and acoustic flooring underlays, fire ratings, and specifications.
01 What is IMO certified underlay?
IMO (International Maritime Organization) certified underlays meet strict fire safety, smoke, and toxicity requirements under SOLAS regulations for use on passenger ships, ferries, and offshore vessels. All our marine underlays carry the CE quality mark with the steering wheel logo, confirming compliance with the Marine Equipment Directive.
02 What thickness of underlay do I need for marine flooring?
For marine carpet installations, 4-8mm underlays are standard. Flamecheck 4mm suits lightweight applications and areas with height restrictions, while 6-8mm provides enhanced acoustic insulation and comfort for cruise ship cabins and corridors. For LVT and vinyl installations, the 1.5mm Duralay Multi-Fit is the optimal choice.
03 Can these underlays be used with underfloor heating?
Yes, Duralay LVT Multi-Fit is compatible with underfloor heating systems. Check the TOG (Thermal Overall Grade) rating — lower TOG values allow better heat transfer. The 1.5mm thickness ensures minimal thermal resistance while still providing acoustic benefits.
04 What is the fire rating Bfl-s1?
Bfl-s1 is a European fire classification for floor coverings under EN 13501-1. “B” indicates limited contribution to fire, “fl” designates the product as flooring, and “s1” means low smoke production. This rating is required for commercial and marine installations where fire safety is regulated.
