Thermal bridging: the heat paths around insulation

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

• Clarify whether a quoted thermal value covers insulation or the whole assembly.
• Ask what baseline supports percentage-loss or savings claims.
• Request connection details at windows, floors, roof and foundation.
• Review the remaining effects of fasteners and supports.
• Confirm that moisture, surface temperatures and structural needs were considered together.
