Walls, Basements & Garages

Walls, basements and rooms above garages need assembly-specific planning. Access, existing finishes, moisture conditions and the relationship between adjacent spaces can all affect the work. This category begins with the room-over-garage discussion in the upstairs comfort guide, where a floor boundary can be overlooked if the enquiry focuses only on the attic.
Use the residential insulation page for the wider service questions and the materials guide for product forms. When you enquire, describe the space, any planned renovation and whether finishes are already open. Ask who handles access and reinstatement, and which requirements belong to the complete wall or floor assembly rather than the insulation alone.
