Laminate Underlay FAQs – Comprehensive Guide
The best underlay depends on your subfloor and needs:
-
Concrete floors: DPM moisture-barrier underlay
-
Floorboards: Fibreboard or rubber crumb
-
Noise reduction: Rubber crumb or thick XPS
-
Underfloor heating: Low-tog specialist underlay
-
General domestic use: Recycled foam or XPS
We’ll recommend the perfect option based on your home.
Most laminate underlays range from 2mm to 5mm.
Thicker doesn’t always mean better — the key is matching the correct underlay to the subfloor.
For example:
-
Underfloor heating: Thinner, low-tog underlay
-
Uneven floors: Fibreboard (4–7mm)
-
High insulation: XPS (3–5mm)
Yes — underlay significantly improves:
-
Sound absorption
-
Thermal insulation
-
Comfort
-
Durability
-
Stability
-
Moisture protection
Using the wrong underlay can cause noise, movement, lifting and premature wear.
Both have benefits:
-
XPS: Lightweight, moisture-resistant, great insulation, excellent acoustic performance.
-
Fibreboard: Better for levelling uneven floorboards and providing solid support.
Choose based on your subfloor conditions, we can advise when you visit the store!
