Technical Specification

Our 21mm Engineered Oak is constructed as a multilayer board, consisting of a Solid Oak face or wear layer of 6mm, with a 15mm quality plywood backing that forms the T&G, and provides a good strong underside suitable for installation by nailing, gluing or floating. The underside is also ‘sealed’ with a final stabilising veneer.

Our Engineered Boards do not have a softwood core and because of this are strong enough to be fitted using any of the 3 common methods; Glue Down, Nail Down or Float.

  • 21mm Overall Thickness
  • 189mm Wide
  • Single Strip Oak Face
  • Mixed Grade, so will contain natural grain and colour variance, sapwood, and various size knots (some filled and sanded). Grade details are explained below
  • 15mm (9-Ply) Eucalyptus Plywood Backed
  • Full 6mm Wear Layer of European Oak
  • 75% Lengths of 1830mm
  • 25% Lengths of 610mm, 915mm or 1220mm
  • Moisture Content 6 – 9%
  • Micro Bevelled Sides & Ends
  • TG4 End Matched
  • 2.08m2 Per Carton
  • 72.8m2 Per Pallet
  • Extra Important Detail;
    • Sealed Underside for Improved Moisture Protection (reduces risk of ‘cupping’ after installation)
    • Extra Stabilising Veneer to Underside (extra stability after installation)
    • Very Accurate Machining Tolerances for Fast & Simple Fitting (saves on fitting costs)
    • Angled T&G Joint for Excess Adhesive (reduces risk of excess adhesive reaching the surface)
  • All our flooring products are machined to very accurate machining tolerances for fast and simple fitting.

Maintenance Guide

Although our engineered products have an underside of high quality plywood and are designed to provide extra stability after installation, they’re still constructed of all natural products.

After proper and sufficient acclimatisation, the conditions during installation should be maintained as consistently as possible thereafter for optimum performance and to avoid dimensional movement of each board within the finished floor.

For information on important, ongoing maintenance, please refer to our Care & Maintenance guide.

Weather, Humidity, Temperature and the Ongoing Maintenance Of Your Flooring

Because oak is a natural, hygroscopic (water absorbent) material, and its dimensions are directly relative to its moisture content, we must control and maintain the relative humidity within our homes to enable the moisture content of our oak flooring to remain constant. This will ensure stability of each board within the finished floor, because failure to do this may force these boards to change dimensionally and structurally. This is not at all a fault of the flooring itself but all to do with the conditions that it’s being forced to endure.

Here’s an example of what can happen when the outdoor temperature is 0°C

The maximum amount of water that a cubic metre of air can hold at this temperature is 5 grams, so when you bring this cubic metre of air inside and heat it to 25°C, the relative humidity drops to only 23%.

We actually recommend a minimum of 40% for optimum floor stability (incidentally, this is also the level that health experts recommend for our bodies too, so good for our floor and good for us).

But it gets worse as the temperature outside falls lower, and this is why the air inside any heated building in the winter can become too dry, which can obviously have an effect on our flooring (and our bodies).

When relative humidity is allowed to drop too low, our flooring is forced to lose moisture itself and will try to curl upwards towards the dry air (similar to a piece of bacon under a grill) in an effort to find moisture.

Any time the temperature outside is well below freezing, relative humidity inside will be below 20% unless you do something to increase it, and not increasing it can have a devastating effect on your oak floor.

Installation Options

Can be floated, nailed down or glued down.

For more information on these fitting methods, please see our Fitting Guidelines guide.

Installation Above UFH
Our 21mm Engineered Oak can also be fitted above underfloor heating when the correct installation guidelines are followed and the necessary levels of heat, humidity and moisture are maintained by the owner after installation. However it should not be used in this situation as your primary heat source because the 21mm thickness can ‘hold’ heat within its structure, so UFH systems can continue to ‘dry out’ the flooring further after installation, even when the correct acclimatisation process has been followed. This can cause dimensional movement within the floor and sometimes create a ‘de-lamination’ effect because the 6mm oak layer is so strong that when it wants to move, it actually ‘pulls away’ from the plywood base.

We recommend using our 15mm board with UFH because it has a lower thermal resistance than the 21mm board, thus allowing the transfer of heat more easily and quickly.

We can supply a Self-Regulating UFH System that’s perfect for use with our Oak Flooring because it never overheats, making it safe and super energy efficient.

IMPORTANT NOTE:

Sometimes the plywood backed engineered boards will seem as if they are ‘bowed’ from end to end when they are first removed from the packaging. This is very common with a plywood backed product because of the difference in molecular structure of the solid oak face and the plywood backing.

It is not a fault with the board and should be expected. It does not cause any problems during installation because of the required staggered joint fixing for an oak floor. Obviously as each board is ‘surrounded’ when fixed, by at least another 4 boards, it is straightened and aligned perfectly every time. In fact, some fitters claim this actually strengthens the floor further.

21mm Thick Boards, 6mm Oak Wear Layer, 189mm Width, 1860mm In Length

Brushed and natural oiled mixed grade engineered oak flooring is a stunning oak floor for any home or venue and is by far one of our most popular engineered oak floors.

This engineered oak flooring is 21mm thick, made up from 15mm of Eucalyptus plywood underside that is fully bonded to 6mm of French oak wear layer. This wear layer of solid oak is itself a single strip that is 189mm wide for beautiful and impressive effect. The full face coverage of the single strip oak beautifully showcases the extra width available when ordering from our engineered oak flooring range.

The brushed and natural oiled mixed grade finish is achieved through ‘brushing’ the face of the planks during manufacture, removing the slightly softer fibres of the oak. After the oak has been brushed, it is oiled with natural waxoil, which creates a natural looking finish to the flooring. After the waxoil is applied, the brushing that happened during its manufacture enhances the beautiful grain features of natural oak, giving a slightly textured surface.

The brushed and natural oiled mixed grade finish is very easy to maintain and should only ever require a light sanding and another coat of wax oil to bring it back to pristine condition if/when required.

Natural open features such as knots are filled and sanded within our brushed and natural oiled engineered oak flooring, creating a fuller and more blended look that still provides an accent of the natural features in the overall look of the finished and installed oak floor.

Having a slightly textured finish means that marks and scratches don’t show up as much as on a smooth finish and because the waxoil colour is natural, if you ever want to darken the colour you can apply another coat of waxoil in whatever colour you choose to achieve the exact finish that you want. Even though brushed and natural oiled select grade engineered oak flooring is a pre-finished product, it still  gives you the freedom to create your own floor appearance that fits in with the rest of your room and your own personal taste.

Brushed and natural oiled engineered oak flooring is one of the most versatile oak floors we stock because it looks great in any room, easily co-ordinating with and complementing your existing décor with its natural appearance and colour. If you want a floor that is hard wearing and easy to maintain with a great look that you can change simply by adding another coat of waxoil to adjust the colour, then brushed and natural oiled engineered oak flooring is for you.
