Homeowner checklist

Siding: materials, insulation and rainscreens

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

• Have the existing wall construction and changing layers identified.
• Compare cladding-product ratings separately from whole-wall performance.
• Ask how water drains around openings and at the base.
• Confirm the rainscreen’s intended drainage and ventilation functions.
• Include local exposure, maintenance access and concealed repairs in the scope.
