Engineered Wood Flooring

High property costs, high end-user expectations for quality finishing, in the midst of a tight construction labour market have motivated the search for more productive, ecologically well disposed and sustainable building products. Timber flooring is a common and popular choice with end users because of its assortment of styles and examples and patterns as well as exuding a warm homely environment. Engineered wood flooring is one of many types of timber flooring available that is dimensionally more stable and reduces the depletion of natural resources through the way it is manufactured.

 

Engineered wood flooring is manufactured by bonding together various layers of wood with grains alternating at 90 degrees at each layer and having a lamella as the top wear layer. It is through such clever integration of materials that makes engineered wood flooring less susceptible to expansion and contraction. Engineered wood flooring is also a more productive option with a simplified installation process as compared to conventional timber flooring.

 

There are wide selections of timber species in engineered wood flooring. Timber being a natural product will have natural attributes e.g. knots, grains and various colours and tone. There can be big contrast of tone and colour even within a single species. In the production process, manufacturers would sort them in categories and collection. Some collections have minimum colour variation and a knot free look, while some would have contrasting tone with prominent knots.

The photographs below show some of the collections available.

Engineered wood flooring can be produced with a single plank lamella or 2 – 3 strips lamella. Single plank generally cost more and would have lesser colour variation and tonality within the board. Functionally, single plank and 2 – 3 strips plank are similar.

  1. Finishing Layer: UV-cured solvent free lacquer or oil, wax.
  2. Hardwood Wear Layer (commonly known as Lamella): Solid wood layer, most commonly 2 – 4 mm thick.
  3. Core Layer: Usually made of hardwood, spruce or compressed plywood with thickness based on manufacturer’s specification. Absorbs stress and strain and keeps the floor stable.
  4. Back Layer: Usually plywood or medium soft wood. Combines with other layers to prevent the floor from cupping and warping.
