Wooden Flooring Underlay
Choosing the right underlay protects the subfloor, cuts noise transfer, and extends the life of the floor above it. Our range covers rolled and foil-backed options for wood and wooden floor underlay, alongside dedicated acoustic underlay for projects where sound insulation is a priority.
Our flooring underlay range is designed to protect, insulate and extend the life of the floor above it. Choose wood floor underlay for solid and engineered boards, wooden floor underlay for general installs, or acoustic underlay where sound insulation matters. Our Strata Acoustic Underlay has already been specified to meet Part E Regulations on real projects, including a Berkeley Group development on the Thames. This range forms part of our complete range of flooring accessories for every stage of installation. Fitting a new wood floor at the same time?

Our Underlay Collection
Part E of the Building Regulations sets minimum standards for airborne and impact sound insulation between dwellings, and it applies to flats, conversions and any multi-occupancy development. Getting the underlay wrong, or leaving it out, can mean a failed pre-completion sound test and a costly remedial fix once the floor is already down.
Our Strata Acoustic Underlay has already met Part E Regulations on a real project: see our Royal Arsenal Riverside case study, a Berkeley Group development on the Thames where our subfloor system delivered high-specification sound reduction to a tight budget and finished height. If you’re specifying flooring for a similar conversion or new-build apartment project, our technical team can help you work out the right build-up.
Trusted by professionals across the UK, our underlay range is backed by technical support and fast, reliable delivery to keep your project on schedule.
Frequently Asked Questions
What is Part E and why does it matter for underlay?
Part E of the Building Regulations sets minimum sound insulation standards for floors separating dwellings. The wrong underlay, or none at all, can mean a failed pre-completion sound test in flats, conversions and multi-occupancy developments.
Which Marldon underlay is suitable for Part E compliance?
Our Strata Acoustic Underlay has already been specified to meet Part E Regulations on real projects, including a Berkeley Group development on the Thames.
Do I need acoustic underlay for a single dwelling house?
Part E requirements specifically apply to floors separating different dwellings, so they are most relevant to flats, apartments and conversions rather than standalone houses, though acoustic underlay still improves comfort in any home.
Can acoustic underlay be used with underfloor heating?
Yes, our Strata Acoustic Underlay is compatible with underfloor heating systems as well as timber and concrete subfloors.
What thickness of acoustic underlay do I need?
Our Strata range is available in A30 (3mm), A50 (5mm) and A100 (10mm) options depending on the level of impact sound reduction required and available floor height.
