📏 Expansion Gap
Leave 10-15mm expansion gap around all perimeter walls. This accounts for natural expansion and contraction due to temperature and humidity changes. Never install flooring without this gap - it can cause buckling.
✓ Underlay Benefits: Improves comfort, reduces noise, provides moisture barrier, and extends flooring life. Always use appropriate underlay for your specific flooring type.
💡 Pro Tip: Perimeter length helps you order trim/skirting boards. Allow extra for joinery corners and transitions.
