Why is an expansion gap important?

Engineered wood flooring is widely valued for its strength and durability, which is why it’s often recommended by builders and architects for use throughout the home. It performs well in areas exposed to moisture and can handle fluctuations in temperature. However, like all wood-based flooring, it still requires an expansion gap.

An expansion gap is the small space left around the edges of a room during installation. Wood naturally expands and contracts in response to changes in temperature and humidity, and without this allowance, the flooring can become unstable over time. Leaving a proper expansion gap is essential to maintain both the performance and longevity of engineered wood flooring.

Creating Expansion Gaps

Expansion gaps should be included around walls, doorways, and fixed objects such as heating pipes. As a general guideline, a 15mm gap is recommended where the flooring meets fixed structures. In larger rooms, slightly larger gaps may be necessary to accommodate increased movement. Regardless of the installation method used, ensuring adequate expansion gaps is crucial. Although it may take a little extra time and effort, doing so will help prevent issues such as warping or buckling in the future.

Keeping Expansion Gaps Consistent

For the best results, expansion gaps should be uniform throughout the installation. This is where spacers come in—they help maintain consistent spacing between the flooring and surrounding surfaces. Using correctly sized spacers along walls and fixed points ensures an even gap all the way around.

There’s no need to worry about the appearance of these gaps, as they are typically concealed once the floor is finished. Skirting boards or mouldings can be fitted to neatly cover the edges, leaving a clean and professional look.
