Its natural composition and FSC certification ensure that it is an environmentally responsible choice, making it suitable for homeowners and professionals seeking both quality and sustainability.
Practicality is at the heart of this underlay. It is compatible with a wide range of floor finishes including laminate, cork, and parquet, making it versatile for different spaces across residential and commercial settings. Its CFC-free, recyclable construction means it can be disposed of safely without polluting water, and its resistance to common building materials such as PVC, linoleum, and synthetic resins ensures a reliable and safe installation.
The Softboard 5mm Underlay is particularly suited for smoothing out minor subfloor unevenness up to 3mm, providing a balanced foundation for your flooring. It also offers thermal resistance of 0.100 m² K/W, improving comfort underfoot and contributing to energy efficiency. Please note this underlay is not suitable for use with underfloor heating systems.
For best results, the underlay should be laid diagonally beneath flooring planks with joints taped securely. Before installation, ensure that the subfloor is clean, level, and dry, and follow all manufacturer and industry guidelines. When correctly installed, the Softboard 5mm Underlay creates a durable, quiet, and stable foundation for your flooring investment.

I used this underlay as part of a full flooring replacement in the bedroom. I had to trim a couple of awkward corners more carefully. There was very little waste after measuring the room carefully. The 5mm thickness was easy to allow for around thresholds and skirting. Once the floor was down, the overall installation felt neat and stable underfoot. It did the job well and suited the installation.
