Slab insulation: the floor, the edge and the ground

Use these steps to plan, check and keep a record of your next actions.

• Confirm how the slab and foundation edge relate structurally.
• Ask which heat paths each proposed insulation layer addresses.
• Review moisture, soil-gas, frost and pest-inspection details together.
• Clarify what a retrofit will leave unresolved.
• Keep drawings and photographs before the work is concealed.
