Should I order a sample first?

Yes if you are comparing colours, matching existing furniture or choosing between rooms. Flooring can look warmer or cooler depending on daylight, wall colour and artificial lighting.

How many packs do I need?

Enter your room size above and the page will round up to full packs. We recommend allowing 10% extra for cuts, corners and waste, or 15% for herringbone and diagonal layouts.

Can this floor be used with underfloor heating?

Use it with underfloor heating only when the product specification confirms compatibility. Follow the fitting guide and keep the finished floor surface within the recommended temperature limit.

What underlay do I need?

The right underlay depends on your subfloor, fitting method and whether you use underfloor heating. Choose a compatible underlay rather than the thickest option.
