Why Oak Flooring

For centuries wood has been the favoured material for flooring. Ecodure Premium European Oak is continuing this tradition in New Zealand homes with its range of beautifully crafted Engineered Oak Flooring, working closely with New Zealand’s leading home building companies, architects, specifiers, developers, designers and countless home-owners. Ecodure Premium Oak Flooring has it all, it is beautiful, elegant, timeless, durable, cost-effective, quick and simple to install, easy to maintain and being an Engineered board it provides all the benefits of being structurally robust.

Every Ecodure Premium Oak Floor has a unique signature with its colour tones and grain characteristics as individual as a fingerprint, with the natural grain enhanced by either an clear oil finish or with a choice of stains. Our boards proudly displaying the distinctive figuring of medullary rays, which are a natural and much sought after feature of Oak. We have a range of beautiful colours available, the range includes oil finished options to display the elegance of natural oak, the lightly white washed Biscotti, the mid chestnut brown Classico, the rustic light brown Bosco,  to the stunning Rustic Oak with an oil finish……one is sure to enhance any interior.

Exceptionally attractive wide format 190mm boards show the grain to perfection, unlike the narrow widths used in multistrip planks. The wider plank width creating the illusion of a more spacious interior, whilst adding a sophisticated, yet warm and inviting feel to your environment. All Ecodure Premium Oak Floors are pre-finished at factory, so there is no need for on−site staining. Perfect for every interior, casual or formal, from stylish apartments to beach-side homes. The warmth of an Ecodure Premium Oak Floor will bring years of pleasure.

We are often asked what the difference is between French, American or European Oak? These are simply common names for different family members of the Quercus (or Oak genus), not an indicator of quality. The Botanical name for European Oak is Quercus Robur and is sourced from Central and Western Europe. European Oak tends to be lighter in colour to American Oak, with less pronounced grain patterns and is available in premier and rustic grades. Ecodure Premium European Oak have a range of selected premium grade which has almost no knots or there is the rustic grade with beautiful knots that enhance the character of the floor.

Our 15mm engineered boards have a super thick 4mm of Premium European Oak applied on an 11mm solid plantation grade, cross-engineered timber plank − no reconstituted or synthetic materials are used, giving an impressive 15mm plank depth. In fact, engineered Oak is superior in durability and stability to solid Oak, as the multi-directional construction of the engineered board counteracts the effects of humidity and temperature fluctuation on natural wood (it is still vital that due care is exercised to NOT expose any natural wooded product to high levels of moisture) by  allowing each board to expand and contract within reason without warping or cupping. Solid boards are far more susceptible to warping along the natural grain lines of the plank.

Some of our selections are finished either with German Treffert solvent−free, water-based polyurethane, UV Lacquered or are simply oiled to show off the natural timber. We have put together a list of frequently asked questions which contain more detailed advice to help you make your choice of an Ecodure Premium Oak Floor.

Easy Maintenance
No need for vacuuming or messy wet mopping, just a simple sweep and swish with a microfibre mop is all that is needed to keep your floor fresh and dust free. Hence the flooring is asthma and allergy friendly, a quick spray of water and swish with a microfibre mop is the only regular maintenance needed to keep your floor looking stunning and dust free. For full details please refer to our Oak Maintenance Guide found in the Additional Information download link.

Allergy Friendly
Ecodure Oak Floors are ideal for people with dust or pet allergies as the tight UNICLIC joins means there is little chance of dust mites or pet dander gathering. A regular swish with a microfibre dust mop and a spray bottle of water is all that is required to maintain your Ecodure Oak Floor.

Ecodure Premium Oak floors are installed in the same manner as any other hardwood timber flooring. It is precision manufactured, resulting in an exceptional quality UNICLIC product. Engineered Oak Floors can either be glued directly to concrete or plywood/particle board subfloors with Mapei 955 adhesives, however we strongly recommend professional installation for all glued floors; or it can be installed as a Floating Floor over the Accord Premium Floating Floor Underlay, which has outstanding compression resistance for comfort underfoot and sustained noise reduction. Floating floors can be installed by a professional, but are also suitable for self-installation by someone competent in DIY. Concrete slabs may need to be moisture sealed with Mapeproof Moisture Barrier.

Stair nosings are also available for all the Oak floor colours.

Adhesives and Moisture Barrier
Ecodure Flooring only recommends Mapei adhesives such as Mapei 995 or 955 for a glue down floor and should a Moisture Barrier be required where Mapei glue is used, Mapeproof is recommended as a Moisture Barrier. For more information or specifications on these products, please visit

Should Moisture Barrier be required with a floating floor, we recommend Mapeproof Moisture Barrier. For more information or specifications on these products, please visit

Accord Premium Underlay
Ecodure Flooring only recommends and uses the Accord Premium Underlay where floors are floated. See our additional information page for full specification on the Accord Premium Underlay.

Hardness Rating
Oak is a medium dent-resistant wood according to the Janka hardness test that measures the resistance of a type of wood to withstand denting. It measures the force required to embed an 11.28 mm steel ball (that’s about the size of a Jaffa!) into wood, at half the ball’s diameter. The higher the number, the harder the wood. The results of testing of various species commonly used for flooring is shown below. This test result is in kiloNewtons (kN), although you may see results shown in pounds force. Wikipedia gives instructions for conversion.

As can be seen at 6kN’s, Oak has half the dent resistancy of Compressed or Strandwoven Bamboo, yet it is twice as dent resistant as any of our NZ Native Timbers – making it a good wearing, timeless, stylish flooring choice that offers medium dent resistancy.

An Ecodure Engineered Oak board provides all the benefits of being structurally robust. All our Engineered Oak boards have a superior 4mm thick solid European Oak layer applied on an 11mm solid plantation grade, cross-engineered timber plank, with no reconstituted or synthetic materials used, giving an impressive 15mm plank depth. As the multi-directional, cross-engineered construction of the engineered Oak is superior in durability and stability to solid Oak, the engineered board counteracts the effects of humidity and temperature fluctuation on natural wood (it is still vital that due care is exercised to NOT expose any natural wooded product to high levels of moisture) by  allowing each board to expand and contract within reason without warping or cupping. Solid boards are far more susceptible to warping along the natural grain lines of the plank.

Environmentally sound
Being an Engineered board, Ecodure Engineered Oak is more environmentally friendly than its solid Oak counterparts, as only a 4mm strip of the valuable Oak timber is used per plank; the plantation grade, FSC Approved backing made from a far faster growing, sustainable timber – this also allowing it to be cost effective……but, without compromise, as the generous 4mm wear layer of the precious, solid European Oak timber can, if ever necessary be sanded time and time again – thus truly making this a floor for a lifetime.

Ecodure Oak flooring selections are either oiled (may require ongoing maintenance), UV Lacquer or in some ranges with top quality German Treffert solvent free polyurathane coatings. T

All Ecodure Oak Floors have either a UNICLIC joint system for tightness and ease of installation or T&G.

Ecodure Oak Flooring come with a no fuss, no worry structural warranty.

Oak Flooring Faqs

ECODURE Premium Engineered Oak is a multi-layered product with a base layer of plantation grade,  fast growing, sustainable timber which are laid in opposite directions (cross engineered) and glued together under high pressure, using top quality Finnish Dynea glues. This base layer in turn then glued to the Oak top layer. The resulting boards are highly stable and suited to almost any environment, from kitchens to living areas, to bedrooms and play rooms. This is quite different from thinner timber veneers which may have a wear layer as little as 1mm thick, or laminates which are uniform photographic images imprinted onto a thin plank. Laminate planks commonly use thin MDF or hardboard which is unstable especially if any moisture is present. Every piece of Oak used in our Engineered floors is solid European Oak, displaying its unique appearance, with naturally occurring variations in colour and grain. Solid Oak is cut from the log as either a crown cut which is a length ways cut through the log or quarter sawn where slices are taken radially into the centre of the log. Both of these boards can warp in either a crowning or cupping pattern around the growth rings of the tree. Solid Oak boards are much more susceptible to seasonal shrinkage, which causes 'rafting' or opening out of the boards, or 'peaking' as boards take on moisture and expand. Both of these are normal responses as the floor responds to the environment, but can be unsightly or even ruin the finished floor. In addition, Solid Oak is one of the least dimensionaly stable timbers available for flooring. Solid Oak floors have been known to expand so much that they even push walls out of position. This will not happen with Engineered Oak planks, enjoy the timeless, grace and beauty of an Oak floor, with stability and peace of mind.

It is not possible to install solid Oak on new concrete as it must be nailed or glued down. Ecodure Engineered Oak on the other hand is suitable for new concrete sub-floors, either as a floating or glue down option.

The labour cost of installing laminates and Engineered floors is very similar, but the resulting floor will be very different. The main difference in cost of flooring installation is between a glued down floor and a floating floor. Remember you will have your floor for many years and the cost of installing a premium wood floor over a laminate floor will pay off over time.

In 3 -5 strip flooring short narrow planks are laminated together into larger sheets, which give a much more varied grainy appearance, not dissimilar to many laminates. Often the shorter, off-cut lengths which have not reached the highest grade are used for 3 or 5 strip floors. Ecodure Premium European Oak floors are manufactured as premium wide (189mm) boards of the higher, less knotty AB grades of timber.

All the flooring ranges are either pre-finished with an oil, UV Lacquered or with a water-based polyurethane, which is solvent free. So, with no messy or time consuming on-site finishing your floor will be ready to walk on in record time.
The benefits of pre-finished flooring, be it from our oiled, UV Lacquered or UV cured, water-based polyurethane coating range. With pre-finished boards you will be able to see the finish before it is installed, so there will be no surprises. Over time, even with the best of care, a few scratches may appear, these can easily be treated - please refer to the Oak Maintenance Guide we have developed on our Additional Information download link.

With the correct Care and Maintenance a floor should last for many years. As Oak is a medium dent resistant wood, it's unlikely it will need sanding to remove unsightly dents for many years, as is often the case with other softer species. If sanding is needed, there is plenty of thickness in all boards for several sandings. Both plank and coating have a warranty.

Sanding of glued down floors is possible, but you must not remove more than 1-2 mm of the Oak layer, as this may weaken the UNICLIC join.

From the Janka Chart can be seen that Oak sits at a 6kN dent resistancy - which means Oak has half the dent resistancy of Compressed or Strandwoven Bamboo, yet it is twice as dent resistant as any of our NZ Native Timbers - making it a good wearing, timeless, stylish flooring choice that offers reasonable dent resistancy. Please refer to the section on Durability where a hardness graph will clarify hardness levels of Oak compared to other species of timber.

Floating or glue down installations are both possible depending on the sub-floor conditions. We have developed common sense Installation Guides which give more advice, please refer to either Installation on Concrete or Installation on Timber Substrate in our Additional Information download link.

Yes, we stock stair nosings to match all our flooring - the treads and risers created from the flooring boards.

The Treffert finish is UV resistant, but it's possible that colour may change over time, due to the amount of UV in the NZ environment. Unlike old-fashioned solvent- based coatings which can darken or turn yellow almost immediately, waterbased polyurethanes are a huge advance;  however the usual common sense precautions we take against our harsh sun should apply. In areas exposed to direct sunlight, like with any other wood, carpet or tiled flooring;  UV protection to the windows, curtains or blinds are recommended and also to avoid placing rugs, pot plants, etc on the floor as these will leave obvious marks when removed. If there is a colour change it is minimised visually, by allowing the floor an equal and even gradual change.

Our flooring has been tested for slip resistance (dry test) and meets this standard.

With a floating floor, the carcasses of the kitchen units should be installed before the floor. Leave fitting of the toe-kicks, end panels which meet the floor and waterfall bench tops until after the floor has been installed. With a glued down floor, the floor can be installed before the cabinets, however take care to protect the floor from tradespeople in the installation period.  For full details, please refer to our Kitchen Floor Installation Guide on the Additional Information download link.

A glued floor is permanently fixed to the substrate with a specialised flexible adhesive. This must be left to cure properly before the floor can be walked on. A floating floor uses the gravity or mass weight of the product along with perimeter trims to hold it in place. Floating floors also use a special underlay which is crush-proof, providing comfort cushioning, acoustic and moisture management, as well as being an excellent draught excluder!

A floating floor is very slightly softer to walk on, while a glue down floor is subtly firmer. Not all installation situations or products are suitable for a glue down floor, while a floating floor can always be installed regardless of circumstances. For more detailed advice on installation please go to our additional information download page and download the guide for either Installation on Concrete or Installation on Timber Substrate as well as Taking the Mystery out of Floating Floors. For specifiers and architects we have a more detailed specification, available on. For specifiers and architects we have a more detailed specification, available on request.

The effectiveness of underfloor heating will be greatly reduced by the density and poor conductive properties of timber flooring. We think on balance it is better not to have underfloor heating. We do have further advice on this, please either contact us for advice or download Underfloor Heating Specification on our additional information downloads page.

The edge of the floors need an even expansion allowance. There is no hard and fast rule for this - the bigger the floor the bigger the allowance. This can be provided under the skirtings and gib board and under kitchen cabinetry. Around doors and floor to ceiling windows an aluminium trim is used which neatens the edge and covers any expansion or shrinkage. The best procedure is to remove skirting boards and leave them off until the floor is down, this enables the perimeter to be seen. If this is not possible, skirtings and architraves will need to be under-cut with a special saw. Where floors adjoin carpet or tiles special trims are available from flooring suppliers.
