Oak Premier Unsealed 135 x 20 mm

Engineered Flooring 135 mm x 20 mm

Premier Oak has a more uniform and cleaner look that brings a refined elegance to a home. The lower knot content of premier Oak gives a more contemporary appearance.

Our engineered wood flooring meets modern requirements and keeps a traditional wood flooring appearance. The multiple layers of plywood backing give support to the visible top layer of the precious hardwood, resulting in a floor that looks and feels like a solid wood floor but that is suitable for under floor heating, can be laid over almost all types of sub floor, and can still be sanded and re-finished after years of use.

If you’re looking for a floor that delivers on character and vibrancy, narrow boards are a great option.

Unsealed products provide the flexibility to finish the wood in any colour once the floor is fitted. This can be anything from a clear sealer, to bring out the beauty of the wood, to a coloured finish to create an individual, bespoke feel. This is ideal for colour matching with an existing floor or simply to introduce a particular shade into a design scheme.

The top layer is kiln dried to between 8-12% moisture content.

The formaldehyde emissions are: 0,01 ppm, pentachlorophenol emissions: <0.8 mg/kg.
Thermal conductivity (W/mK) is 0,10W/mK.

Suitable for secret fixing to ply, battens or joist subfloor, floating on an underlay or a fully bonded installation to a screed subfloor. The unsealed board is supplied with a micro bevel along the length of the board, pre- sanded requiring only a light 100/120 grit sand to finish.

Nail Fitting Nail fixing is usually done via a nail gun, e.g Porta-Nailer, where a serrated nail is inserted through the tongue at 45 degrees.

Stick Down Sticking involves the use of an adhesive to bond the wood flooring to either a concrete/screed sub floor or to a ply/chipboard sub floor.

Floating A floating floor is not physically connected to the sub floor. Normally laid on an underlay, the floor is joined by gluing the tongue and groove together or by using a click system.
