Engineered Wood Flooring Installation Guide

Engineered wood flooring is a modern, attractive and innovative type of flooring that resembles solid wood flooring so closely only a professional can tell them apart. They are suitable for all areas of the house except bathrooms and wet areas. This installation guide will help you to successfully install your engineered wood flooring perfectly on your first try.


Acclimatising Engineered Wood Flooring

Because variation in temperature and moisture level can cause flooring to expand or contract, all flooring should be acclimatised before installation. This ensures that the flooring does not buckle or warp as it adjusts to its new climate. Due to their stability, engineered floors take less time to acclimatise than solid wood floors, but we recommend they  be left for at least 5 days before installation. To correctly acclimatise your engineered floor it should be left flat in the room it is going to be fitted at normal room temperature.


Subfloor and Underlay

One of the first actions you should take is to check the subfloor is even. In some cases, a slight unevenness can be corrected with the right sort of flooring underlay, but often remedial work will be needed on the subfloor itself. This can include getting a product from our accessories range to smooth out concrete floors in order to level them.

If you have a wooden subfloor a moisture-proof underlay may not be necessary, but on a concrete subfloor this will definitely be required. Over a concrete subfloor you will need to use an underlay which has a built in vapour barrier like Cushion Plus White Underlay, while over a wooden subfloor you can use the Cushion Standard White Underlay.

The type of underlay you need will also depend on whether or not you have underfloor heating. For installations over under floor heating we recommend using Cushion Heat Flow underlay.

Superior underlays like Cushion Ultra Silver Underlay and Cushion Premium Black Underlay can be used to give better support to your new flooring which prolongs the life and also aids installation by removing some minor imperfections from the sub-floor.

Also for improved noise reduction we recommend the Cushion Acoustic Pro Underlay, bringing peace and quiet to the room.


Click System Installation

Most engineered wood floors are installed with a simple click system. Click System Floating Installation is the most common and DIY friendly installation method because it is the easiest and the fastest to do, can be installed over any type of subfloor and it does not require any special skills or prior experience in installing floors as the boards just click together with no need for any glue.

Each board has a click profile on all four sides to join the boards together. Simply insert the tongue into the groove at a high angle and then push the board down; the boards will then click together.

You will need to leave a 15mm expansion gap around the perimeter of the room. To maintain this gap during installation you can use spacers which are provided in installation kits (purchased separately).


Covering the Expansion Gap

After you have installed the floor you can cover this expansion gap with scotia / beading or you can replace your old skirting boards with new ones, this gives a much more professional finish. The 15mm expansion gap also needs to be left in doorways where the floor follows through from one room to another; we have a full range of door profiles available to match your floor.



Inspect all materials carefully before installation. Wood is a natural product containing variations in colour, tone and graining. Some variation in colour is to be expected in a natural wood floor. Beautiful hardwood floors are a product of nature and therefore not perfect. These floors are manufactured in accordance with accepted industry standards, which permit a defect tolerance of 5%. Even though our product goes through many inspections before it leaves the plant, it is the responsibility of the customer and installer to perform a final inspection prior to installation. Any warranties offered with this product do not cover materials with visible defects once the product is installed.



It is the responsibility of the owner/installer to determine if the jobsite sub-floor and job site conditions are environmentally and structurally acceptable for wood floor installation. The installer/owner is responsible for wood failure resulting from or connected with sub-floor, subsurface, job site damage, deficiencies or using inadequate accessories after the hardwood flooring has been installed.



Always read the full manufactures recommended installation guides before installation which you will find in every 3rd pack of flooring.
