What is the best underlay for wood flooring?

The best underlay depends on your floor thickness and room type. We recommend a 3mm underlay for floors up to 15mm thick, a 5mm underlay for anything thicker, and a special 4mm underlay if you have water-based underfloor heating.

How do I install tongue and groove flooring?

To install tongue and groove flooring, ensure your subfloor is clean and level. Apply wood glue to the groove edge of each plank, then fit the tongue of the next board into it. This flooring can be laid as a floating floor, meaning it isn’t fixed directly to the subfloor. Always leave an expansion gap around the edges.

Is engineered wood flooring suitable for underfloor heating?

Yes, but only with water-based underfloor heating systems.

What are the most popular finishes for engineered wood flooring?

Brushed & lacquered, brushed & oiled, and lacquered are our customers top choices.

Can engineered wood flooring be laid over tiles or old vinyl?

Yes, as long as the surface is flat, clean, and stable.

What’s the difference between click-lok and tongue-and-groove engineered wood?

Click-lok is quicker to install, while tongue-and-groove offers a traditional, glued joint.

Will engineered wood flooring darken or lighten with age?

Yes, some colour change over time is completely natural.

What Is a Wear Layer and Why Does It Matter?

The wear layer is the top protective surface of your floor – it resists damage and determines how long your floor will last.

How Long Does It Take to Fit New Flooring?

Fitting takes 1–4 days depending on the flooring type – but be sure to allow extra time for acclimatisation, especially with wood floors.

Customer Questions

What is engineered wood flooring?

Engineered wood is real wood on top, with stable layers beneath.

Do I need to acclimatise my wood flooring before fitting?

Yes, you must acclimatise your wood flooring before installation. For engineered wood, allow 48–72 hours; for solid wood, give it at least 7 days. Keep the packs flat, unopened, and in a room with stable conditions.

Can I install wood flooring over underfloor heating?

Yes, you can install wood flooring over underfloor heating—but it must be a water-based system. Never use electric underfloor heating with wood flooring, as it can overheat and damage the boards.

Do I need expansion gaps when fitting wood flooring?

Yes, always leave an expansion gap of 10–15mm around the perimeter of your wood flooring. This allows the wood to expand and contract naturally with changes in temperature and humidity.

Can engineered wood flooring be sanded?

Yes, engineered wood flooring can be sanded, but only if the top wear layer is thick enough—usually at least 3mm. Thinner layers may not allow for sanding without damage.
