Insulation & Air Sealing · Garage & Floor Insulation

Where suitable, to insulate and seal irregular floor areas.

Questions

Frequently asked questions

Can insulation improve rooms above garages?

Yes. Insulating and sealing the floor and shared walls helps, while keeping the fire separation intact.

Floors over garages are often under-insulated and leaky, and the garage below is unheated.

Does sealing help with garage smells?

Air sealing between the garage and home helps keep fumes out of living spaces.
