A Pukka Guide: The Definitive Handbook to Engineered Wood Flooring
- 13 min reading time
For homeowners and designers seeking the classic elegance of natural timber combined with superior modern performance, engineered wood flooring stands as the definitive choice. It delivers the authentic look and feel of solid wood while overcoming many of its traditional limitations, making it the perfect solution for contemporary living.
At Pukka Flooring, we understand that choosing a floor is a long-term investment. This comprehensive guide will demystify the construction, benefits, and variety of engineered wood, helping you select the perfect floor for your home.
The Anatomy of Engineered Wood
While engineered wood looks identical to solid wood on the surface, its clever, multi-layered construction is what gives it its exceptional dimensional stability and resilience.
1. The Wear Layer (Veneer)
The top layer is the wear layer, or veneer, which is a slice of genuine hardwood (such as Oak, Walnut, or Ash). This is the part you see and walk on, providing the natural texture, colour, and character of a real wood floor.
The thickness of this veneer is crucial, as it determines the floor's lifespan and its potential for sanding and refinishing. A thicker wear layer (typically 3mm or more) allows the floor to be sanded multiple times over its life, giving it a second or even third life when it begins to show signs of wear.
2. The Core Structure
Beneath the veneer lies the core structure, which is the engine of the floor's stability. This core is made up of multiple layers of material bonded together in a cross-ply formation. This alternating grain direction is the secret to engineered wood's stability, as it counteracts the natural tendency of wood to expand and contract with changes in temperature and humidity.
The materials used for the core can vary, each offering different performance characteristics:

|
Plywood Core
|
Multiple layers of thin wood (ply) bonded together.
|
Excellent dimensional stability; highly resistant to moisture and temperature fluctuations.
|
Kitchens, conservatories, and use with underfloor heating (UFH).
|
|
HDF Core
|
High-Density Fibreboard.
|
Very dense and resilient; often features click-lock systems for easy installation.
|
High-traffic areas like hallways and living rooms.
|
|
SPC Core
|
Stone-Plastic Composite.
|
Highly waterproof and extremely stable.
|
Areas prone to dampness, such as utility rooms or well-ventilated bathrooms.

Practical Benefits of Engineered Wood Flooring
The unique construction of engineered wood provides several key advantages over traditional solid wood:
•Superior Stability: The cross-ply core structure significantly reduces the risk of warping, cupping, or gapping, making it suitable for environments where humidity fluctuates.
•Underfloor Heating Compatibility: Engineered wood is the ideal choice for homes with water-based underfloor heating (UFH) systems. Its stability ensures it can handle the temperature changes without damage, while its construction allows for efficient heat transfer.
•Versatile Installation: Engineered planks can be installed using several methods, including floating (with a click system), secret nailing, or the glue-down method for maximum stability.
•Longevity: With a robust wear layer, a high-quality engineered floor can easily last 30 to 50 years, especially since it can be restored through sanding and refinishing.
Choosing Your Finish: Aesthetics and Protection
The finish applied to the wear layer not only defines the look of your floor but also its durability and maintenance requirements.

|
Appearance & Feel
|
Protection & Maintenance
|
|
Brushed & Oiled
|
Natural, matte look with a subtle texture that highlights the wood grain.
|
Oil penetrates the wood, offering a natural, breathable barrier. Allows for easy spot-repair of scratches.
|
|
Lacquered
|
Smooth, sealed surface with a slight sheen (or a flat look with Matt Lacquered).
|
Creates a durable, protective layer on the surface, offering high resistance to wear and spills.
|
|
Distressed
|
Features hand-scraped or artificially aged marks, knots, and textures.
|
Adds character and helps conceal minor wear and tear, creating a rustic, heritage aesthetic.
|
Thickness Matters
Engineered wood comes in a range of thicknesses (e.g., 10mm, 14mm, 20mm). The overall thickness impacts the feel underfoot and the thermal properties, while the wear layer thickness determines the refinishing potential.
When selecting your floor, consider the following:
•Low Profile (10mm - 13mm): Ideal for renovations where existing floor heights or door thresholds are a concern.
•Standard (14mm - 15mm): A durable and versatile choice suitable for most residential applications.
•Premium (18mm - 20mm): Our most robust offering, providing a substantial feel underfoot and maximum longevity, perfect for high-traffic areas or long-term use.
By understanding these key components, you can confidently choose an engineered wood flooring solution that provides a beautiful, durable, and truly "pukka" foundation for your home.
