Expansion Gap Calculator
Calculate the required expansion gap for flooring materials based on length, material type, and expected temperature change.
How to Use the Expansion Gap Calculator
- Enter the total floor run length in metres.
- Select the flooring material.
- Enter the expected temperature change in °C.
- Click Calculate to see total gap and per-side gap.
Anwendungsfälle
- •Installing wood, laminate, or vinyl plank flooring.
- •Planning perimeter gaps around fixed obstacles.
- •Heated floor system installation planning.
- •Flooring installation in regions with large seasonal temperature swings.
Formel
Gap = L × α × ΔT, where α is the thermal expansion coefficient of the material.
Häufig gestellte Fragen
Why do floors need expansion gaps?
Flooring materials expand and contract with temperature changes. Without gaps, buckling or warping can occur.
Which material expands the most?
Vinyl (LVP) has the highest expansion coefficient (~30×10⁻⁶/°C), requiring larger gaps than wood or laminate.
