The Baseline SL Perforated Underlay is specifically engineered for use beneath wood flooring installed over underfloor heating systems. Its unique perforated construction minimises thermal resistance, allowing warmth to travel efficiently from the heating system through to the floor surface — ensuring consistent, responsive heat distribution throughout your space.
Unlike standard underlays, the Baseline SL is designed with perforations that actively facilitate heat transfer rather than impeding it. The dual-layer construction combines a perforated green foam upper with a reflective silver foil backing, delivering thermal efficiency alongside structural support for your floor.
A fully integrated moisture barrier is built into every roll, providing continuous protection against rising dampness — safeguarding both your underfloor heating installation and the longevity of your wood flooring above.
First to market in the UK
The Baseline SL was exclusively introduced to the UK market by Woodfloors4u, making it one of the most advanced perforated underlays available for underfloor heating applications in the country.

Why choose Baseline SL
Optimised heat transfer
The perforated design minimises thermal resistance, so your underfloor heating system works at peak efficiency — reducing energy use and improving warmth distribution across the full floor area.
Integrated moisture protection
A built-in moisture barrier prevents rising dampness from penetrating the subfloor, protecting both the underfloor heating system and your wood floor from the effects of moisture over time.
Acoustic comfort
With an impact sound reduction rating of 19dB, the Baseline SL noticeably dampens footfall and airborne noise, making it well suited to both residential and commercial installations.
Engineered for wood flooring
Designed specifically for use beneath engineered and solid hardwood floors on underfloor heating systems, the Baseline SL is the professional choice for installations where performance and longevity matter.
