When choosing engineered wood flooring, one key decision is whether to go with 3 ply or multi ply construction. At first, it might not seem like a big deal, but this choice affects stability, durability, and how well your flooring handles changes in temperature and humidity. Let’s break it down so you can make the right call for your home.
What Makes Up Engineered Wood Flooring?
Before weighing up the differences, it helps to understand how engineered wood flooring is built. Unlike solid wood, which is a single piece, engineered wood consists of multiple layers. These layers give it extra strength, helping to prevent warping while making it a great option for wider planks. The number of layers—known as “plies”—is what sets 3 ply and multi ply flooring apart.
What Is 3 Ply Engineered Wood Flooring?
3 ply flooring has, as the name suggests, three layers: a hardwood top layer (veneer), a core layer made of softwood or plywood, and a backing layer for balance. Picture it like a well-made sandwich, with the middle providing most of the structure.
Pros of 3 Ply Flooring:
More affordable – A budget-friendly choice compared to multi ply.
Lightweight and easy to install – Ideal for DIY projects and quick renovations.
Has a bit more flex underfoot – Some people prefer how it feels when walking on it.
Cons of 3 Ply Flooring:
Less stable in changing conditions – More likely to expand or contract with humidity shifts.
Thinner overall construction – Might not be the best option for high-traffic areas.
What Is Multi Ply Engineered Wood Flooring?
Multi ply flooring consists of five or more layers of plywood beneath the hardwood veneer. The layers are arranged in a crisscross pattern, making it more resistant to movement caused by changes in moisture and temperature.
Pros of Multi Ply Flooring:
More stable – Better at handling moisture and temperature changes.
Stronger structure – A solid choice for busy areas and underfloor heating.
Thicker wear layer options – Can be sanded and refinished more times over its lifespan.
Cons of Multi Ply Flooring:
More expensive – Extra layers mean higher costs.
Heavier and more rigid – Not always as simple to install.
What Thickness Works Best for Engineered Wood Flooring?
The best thickness depends on where and how the flooring will be used. For most homes, 14mm to 20mm is a good range. If you’re installing flooring over underfloor heating, 15mm multi ply tends to perform well. Thicker options (18mm or more) are great for durability and can be sanded down multiple times if needed.
What’s the Best Plywood for Engineered Flooring?
The type of plywood used in the core makes a difference. Birch plywood is a top choice because it’s strong and holds up well against moisture. Some flooring uses poplar plywood, which is a bit less dense but still works well. High-quality adhesive is also important to prevent layers from coming apart over time.
Which Is Better: Engineered Wood or Plywood?
This is a common question, but it's not really a fair comparison. Engineered wood flooring already contains plywood, with a top layer of real hardwood. It’s like comparing a finished product to one of its raw materials. If you want the look of hardwood with better stability, engineered wood flooring is the way to go.
What’s the Best Ply for Flooring?
If you’re looking for durability and resistance to warping, multi ply flooring is the better option. The extra layers help it stay in shape over time, even in rooms with changing humidity. If cost and ease of installation are bigger concerns, 3 ply flooring still holds up well, particularly in drier, low-traffic spaces.
Which One Should You Go For?
If your flooring will be in a space where moisture and temperature fluctuate—such as a kitchen or conservatory—multi ply is the safer bet. It’s built to handle those changes and lasts longer in demanding conditions. If you’re after a cost-effective solution for a bedroom or home office, 3 ply could be the right fit.
