Low Maintenance: Easy cleaning, with periodic refinishing extending lifespan.
Oak Engineered Wood Flooring Overview
Oak engineered wood flooring is an engineered wood floor with a genuine oak surface layer over a multi-layer core and a balancing backing veneer. The oak surface is real wood, and it is what gives the floor its grain, its colour variation and its ability to be sanded and refinished within the limits of the surface layer. The multi-layer core is what limits the movement of the plank and allows it to be used where a solid oak plank of the same width would move more.
This page covers the oak engineered wood range as a whole: the structure, the specification framework, the oak grades and surface finishes, the difference between solid oak and engineered oak, the applications, the moisture behaviour, the customization and wholesale terms, and the installation and maintenance requirements. The 12mm oak plank and the three-layer herringbone oak format are separate products with their own pages, where the thicknesses and grades for that product are stated; this page explains what the figures mean and how to compare them.
The range is supplied for residential interiors, hotels and hospitality, office interiors, apartment developments and commercial interior projects. It is a wood floor and not a waterproof floor.
Oak Engineered Wood Flooring Structure
The plank has three functional layers, and the same three roles apply across the range whatever the product.
The top layer is the oak wear layer. It is a genuine oak layer, not a printed film, and its thickness determines how many times the floor can be sanded and refinished. The oak grade and the surface treatment determine the appearance.
The core layer is the structural layer. It is a multi-layer core bonded with the grain running in alternating directions, which limits the movement of the plank and gives the floor its dimensional stability. The core material for a given product is stated in its specification as a single material, and it may be a birch plywood or another hardwood plywood depending on the product.
The backing layer balances the plank. It counteracts the pull of the oak surface and helps keep the plank flat.
For a typical configuration in this range, the layers are commonly specified with an oak wear layer of about 3mm, a total plank thickness in the region of 14 to 15mm, and a multi-layer core accounting for the balance of the thickness; this is an example of a common build, not a specification for every product, and the layer thicknesses for an order are confirmed in the quotation. A cross-section of the plank showing the actual materials and thicknesses is part of the product documentation and is supplied on request. The three-layer herringbone format uses the same three roles with a different plank geometry, and it is specified on its own page.
Product Specifications
The table states the fields that are specified for a product in this range, and where each value is stated. The values themselves are given on the product page and confirmed in the quotation; this page does not repeat them, because the range covers several constructions.
| Specification | Where the value is stated |
|---|---|
| Product type | Oak engineered wood flooring |
| Oak grade | Per product, per the factory grading system |
| Total thickness | Per product, confirmed in the quotation |
| Oak wear layer thickness | Per product, confirmed in the quotation |
| Core material and species | The single core material for that product |
| Backing layer | Per product |
| Plank width and length | Per product |
| Surface finish and gloss level | Per product |
| Joint system | The actual joint system for that product |
The total thickness and the oak wear layer thickness are separate figures and should be read together: the total thickness describes the whole plank, while the oak layer determines how much material is available for refinishing. A thicker plank is not automatically more durable; the surface performance depends on the oak layer, the finish and the maintenance.
Material properties such as the density of the oak, its hardness and its moisture content are properties of the wood and are stated with their test method and their conditions. The hardness of oak is reported as a Janka test result for the species, with the test method stated, and it is not used as a general durability claim for the finished floor. Where a fire classification is quoted for a product, it is the classification stated in that product's test report under the standard of the destination market; it is not a general property of oak flooring.
The specification sheet and the test reports held for a product are supplied on request, before the order, together with the sample; the report name, the number and the testing laboratory are stated with each document, and where a report is not held it is stated as not held.
Oak Wood Grades and Surface Finishes
Oak is graded before production, and the grade determines how much natural variation the floor shows. The grades used for this range are stated per product, and the grade names correspond to the grading system the factory actually applies rather than to a generic scale; the grade is confirmed on a sample, because the same name can mean different things between suppliers.
In general terms, a cleaner grade limits knots and colour variation, an ABC or AB grade shows moderate character, and a rustic grade allows larger knots, filled areas and more colour variation. The grade also affects the yield from the timber and therefore the cost, which is why grade and plank width are usually decided together when a project budget is being set: a cleaner grade in a wide plank costs more than a rustic grade in the same width, and the combination is chosen for the room rather than for the grade name alone.
The surface finishes available are the ones actually produced. A natural finish shows the oak with minimal colour change; a smoked finish darkens the wood through a treatment rather than a stain; a brushed finish raises the grain; a matte finish reduces reflection; a UV lacquered finish forms a film on the surface; and an oil finish penetrates the wood rather than forming a film. A lacquered floor is cleaned and, when the film wears, recoated or refinished, while an oiled floor is maintained with the appropriate oil as the surface dries out; the two are not maintained with the same products. The care routine for each finish is covered on the hardwood floor maintenance page.
Solid Oak Flooring vs Engineered Oak Flooring
The two products are different, and the comparison is set out here so that a buyer can tell which one a project needs; the page itself is about the engineered product. The wider comparison of the two categories, including how they behave over time and how they are maintained, is covered on the engineered wood versus solid hardwood page.
| Comparison item | Solid oak | Engineered oak |
|---|---|---|
| Construction | Milled from a single piece of timber | Genuine oak layer over a multi-layer core and backing |
| Wood composition | Oak through the full thickness | Oak surface layer with a plywood core |
| Dimensional movement | Moves with humidity across the full width of the plank | The cross-laminated core limits the movement |
| Installation | Commonly nailed or glued to a suitable subfloor | Floating or glued, depending on the product and the subfloor |
| Refinishing | Sanded and refinished more than once, subject to remaining thickness | Sanded and refinished within the limits of the oak layer thickness |
| Suitable applications | Where a solid oak plank is wanted and the subfloor and humidity allow it | Where a genuine oak surface is wanted with greater dimensional stability and wider plank options |
The number of times a floor can be refinished is not a fixed figure for either product: it depends on the surface layer thickness, how much material remains above the core or above the tongue, and the condition of the floor, and it is confirmed for the product rather than stated as a general number.
Applications
The range is used in residential interiors, including living rooms, dining areas, hallways and bedrooms; in hotels and hospitality projects, including guest rooms and public areas; in office interiors; in apartment developments; and in commercial interior projects.
The checks are made in a fixed order. First the room and the traffic: a hotel guest room and a hotel lobby are different environments, and the expected traffic decides how much oak layer is wanted. Second the finish and the maintenance routine: a lacquered finish is cleaned and recoated, an oiled finish is maintained with oil, and the routine has to match what the operator can actually carry out. Third the subfloor and the installation: the flatness and moisture condition of the subfloor and the joint system determine whether the installation can proceed as planned. The pattern or the species alone does not decide suitability for a commercial interior.
The floor is not a waterproof floor and is not intended for bathrooms with a shower, laundry rooms with a floor drain or any area with standing water. A kitchen or a basement is assessed on the specific conditions rather than on a general description: in a kitchen, spills are frequent and the surface protection and the prompt removal of water matter; in a basement, the moisture condition of the slab is tested and dealt with before any floor is laid, because the floor covering does not stop moisture rising through concrete.
Where the project includes underfloor heating, the compatibility and the temperature limits are confirmed from the installation instructions for the specific product and from the heating system's requirements, because they depend on the construction, the oak layer thickness and the heating system.

Installation and Maintenance
The subfloor should be flat, dry and sound, and the flatness and moisture limits are those stated in the installation instructions for the specific product and joint system. The installation method is stated in each product's specification, and where the product can be installed as a floating floor or fixed to the subfloor, the choice depends on the product's construction, the subfloor condition and the project's requirements.
The acclimation period and the conditions, the expansion gaps and the permitted indoor humidity range are those stated for the product rather than fixed figures, because they depend on the construction, the dimensions and the site conditions. Routine maintenance is dust removal and damp mopping with a cleaner intended for the finish; excess water should be avoided. The detailed installation requirements are covered on the engineered wood flooring installation guide, and the care routine for each finish is covered on the hardwood floor maintenance page.
Frequently Asked Questions
1. What is oak engineered wood flooring?
It is an engineered wood floor with a genuine oak surface layer over a multi-layer core and a backing veneer. The oak surface is real wood, and the cross-laminated core limits the movement of the plank.
2. Does engineered oak flooring have a real wood surface?
Yes. The surface layer is genuine oak, not a printed film, and that is what distinguishes engineered oak from laminate and from vinyl. The thickness of the oak layer determines how many times the floor can be refinished.
3. What is the difference between solid oak and engineered oak flooring?
Solid oak is milled from a single piece of timber and moves with humidity across its full width. Engineered oak has a genuine oak layer over a cross-laminated core, which limits that movement and allows wider planks. The comparison table above sets out the differences.
4. What wear layer thicknesses are available?
The oak layer thickness is stated for each product, and the values for an order are confirmed in the quotation. A common configuration in this range uses an oak layer of about 3mm with a total plank thickness in the region of 14 to 15mm; that is an example, not a specification for every product, and it is separate from the total plank thickness.
5. Can engineered oak flooring be refinished?
It can be sanded and refinished within the limits of the oak layer thickness. The number of times depends on how much material remains above the core and on the condition of the floor, and it is confirmed for the product rather than stated as a general number.
6. Is oak engineered flooring suitable for underfloor heating?
It depends on the construction, the oak layer thickness and the heating system, and the compatibility and temperature limits are confirmed from the installation instructions for the specific product and from the heating system's requirements.
7. Can I customize the color and plank dimensions?
Customization depends on the oak grade, the finish, the dimensions and the order size, and the options available are confirmed in the quotation. A change of grade or dimensions can affect the core construction and the tooling, so the customized configuration is confirmed before production.
