Underfloor insulation (#189080)

Please quote to: Supply and fit insulation under the floor of my house. Easy access crawl space underneath the floorboards. Approx. 120 sqm, 1950's build.

Please mention the options for material that you would use, and it's "R" rating. Note it can get quite damp under there with rainfall, so the material needs to withstand dampness.

Thanks,
Brett.
