Manufactured with a patented closed-cell structure sandwiched by highly reflective foil facings and pierced with tiny, evenly-spaced perforations, Kingspan AIR-CELL Permiwall® allows water vapour permeance while helping to achieve a 6-star house energy rating. (Patent No.2012100976)
  • Australian made
  • 3-in-1 insulation
  • vapour-permeable membrane and radiant barrier
  • Wall cavities remain unfilled and accessible for services

Most people when retrofitting this type of insulation will fasten it to the roof or wall battens with wafer head tek screws and tape the overlaps. Use some of the tapes to help you position it, then screw it off.

The insulation should be installed to the underside of the roof purlins or battens, you can nail or screw it as appropriate, Tape the edges and overlaps to seal in a blanket effect.

The short answer is yes. It would depend on the purpose of the dwelling as to what insulation will be best suited. It will mean a cooler shed in summer and a warmer shed in winter. You can email for advice.
