Why Proper Expansion Gaps Are Your Luxury Vinyl Flooring’s Best Defense Against Seasonal Temperature Changes

When temperatures fluctuate throughout the seasons in the Hamptons, your luxury vinyl flooring experiences subtle but significant changes that can impact its performance and longevity. Understanding proper expansion gap spacing techniques isn’t just technical knowledge—it’s essential protection for your flooring investment.

Understanding Why Vinyl Flooring Expands and Contracts

Vinyl is susceptible to temperature changes in its ambient environment which will cause the vinyl flooring to expand and contract with normal hot and cold fluctuations. When temperatures rise, vinyl planks will expand and contract together, and when temperatures drop, they contract. Despite their synthetic composition, LVT (Luxury Vinyl Tile) and LVP (Luxury Vinyl Plank) flooring expand and contract with changes in humidity and temperature.

Because vinyl is susceptible to changing temperatures, the floor will slightly shrink or contract when temperatures drop and then expand when temperatures rise. This natural movement becomes particularly noticeable during seasonal transitions when temperature swings are most dramatic.

Proper Expansion Gap Measurements

The standard recommendation for expansion gaps is clear and consistent across manufacturers. For both LVT and LVP, a minimum expansion gap of 4mm is recommended, though gaps between 6mm and 8mm are also acceptable, subject to the specific guidelines provided by your flooring’s manufacturer. The recommended size for an expansion gap for luxury vinyl flooring is at least 4mm.

In American measurements, standard expansion gaps should be 1/4 inch wide between vinyl flooring and walls to allow for natural expansion and contraction. Typical vinyl plank flooring guidelines will recommend leaving a ¼-inch space along the perimeter of the room in which the flooring is to be installed, which we call an “expansion gap.” This gap leaves a healthy amount of space for the vinyl to expand without buckling.

For larger installations, the requirements increase. If the floor is less than 50 ft in length or width, leave at least a ¼-inch expansion gap around the entire perimeter. If the floor is between 50–85-ft, increase the expansion gap to ½-inch around the entire perimeter.

Installation Best Practices

Proper installation technique is crucial for maintaining consistent gaps. Use spacers every 12-18 inches along walls during installation to maintain consistent expansion gaps throughout the room. This ensures uniformity around the entire perimeter and prevents the common problem of irregular spacing that can compromise the floor’s ability to move naturally.

To avoid this, we recommend maintaining uniform “expansion gaps” around the perimeter of the floor or at any vertical obstruction when installing. This includes areas around doorframes, cabinets, and any fixed objects that protrude from the floor.

Seasonal Temperature Management

Maintaining a controlled indoor environment significantly reduces expansion and contraction stress on your flooring. Always be sure to keep the installed environment temperatures consistently between 65°F and 80°F. Also be sure to keep any radiant (in-floor) heating systems to a temperature that will not heat the floor above 85°F.

Areas with prolonged exposure to direct sunlight should have suitable window coverings to lessen the amount of generated heat that will be exposed on the floor, especially during peak sun hours. This is particularly important in Hamptons homes with large windows facing the ocean or bay.

Consequences of Inadequate Expansion Gaps

When expansion gaps are insufficient or inconsistent, several problems can develop. Neglecting to incorporate this gap can lead to damage, particularly if the floor expands significantly. This often manifests as bulging or lifting, particularly at the centre of the room. This phenomenon, known as a “pinch point,” occurs when expanding flooring comes into contact with a wall or door frame, creating upward pressure on the boards.

Such close encounters between the floor and a wall, for example, can result in a noticeable and unsightly buckling or peaked appearance. Over time, repeated cycles of expansion and contraction can eventually cause warping or bending.

Maintaining Your Investment

Proper expansion gaps prevent flooring issues like buckling, warping, and lifting of planks caused by temperature and humidity changes. Regular inspection of these gaps, especially during seasonal transitions, helps ensure your flooring continues performing optimally.

Remember that to achieve the optimal expansion gap, it’s crucial to follow the manufacturer’s detailed guidelines closely. Additionally, acclimatising the flooring before installation is highly advisable. This preparation step allows the material to adjust to your home’s specific environment before installation begins.

Proper expansion gap spacing isn’t just a technical requirement—it’s insurance for your flooring investment.
