Frequently Asked Questions
What is Lignum Core flooring?
Lignum Core is the luxury vinyl range from Lignum, the brand behind Lignum Fusion laminate. It is made in two versions. Lignum Core Rigid Vinyl is a 5mm SPC click floor with a 1mm underlay attached. Lignum Core LVT Dryback is a 2.5mm glue down floor. Both are 100% waterproof and carry a 20-year guarantee.
What is the difference between Lignum Core Rigid Vinyl and LVT Dryback?
Rigid Vinyl has a stiff SPC core and clicks together as a floating floor with no adhesive, so it is quicker to fit and suits DIY projects and renovations. LVT Dryback is a thinner 2.5mm flexible vinyl that is glued to a smooth, level subfloor. It gives a very solid, quiet finish that suits large open-plan rooms. Both share the same decors, a 0.5mm wear layer and a 20-year guarantee.
Is Lignum Core waterproof?
Yes. Lignum lists both Lignum Core Rigid Vinyl and Lignum Core LVT Dryback as 100% waterproof, so they can be used in kitchens, bathrooms, utility rooms and hallways. Both also have an R10 slip rating.
Is there a Lignum Core herringbone?
Yes. Lignum Core herringbone is made in every oak shade in both versions. The rigid vinyl herringbone uses 610 x 122mm click blocks packed as 15 left and 15 right blocks marked A and B. The dryback herringbone uses 590 x 118mm blocks that are glued down.
Does Lignum Core Rigid Vinyl need an underlay?
No separate underlay is needed. Lignum Core Rigid Vinyl has a 1mm IXPE acoustic underlay already bonded to each plank, which Lignum rates at a 21dB impact sound reduction. A vapour barrier may still be needed on some subfloors. The dryback version is glued directly to the subfloor and does not use an underlay.
Can Lignum Core be used with underfloor heating?
Yes, both versions are suitable for underfloor heating. Lignum's installation guidance for the rigid range sets a maximum subfloor temperature of 27 degrees C. After fitting, the heating should be brought up gradually by about 2 degrees a day.
What is the difference between Lignum Core and Lignum Fusion?
Lignum Fusion is a 12mm AC4 laminate with an HDF core that is not waterproof, so it suits dry living spaces. Lignum Core is a vinyl floor that is 100% waterproof and can be used in any room including kitchens and bathrooms.
