Shed or Garage Insulation Installation Guide

Simple step by step guide to installing Foilboard® GREEN rigid Shed or Garage Insulation


Step 1

Foilboard® GREEN rigid insulation panels should be installed between the wall girts and to the underside of the roof batterns/purlins.

Step 2

Mark the measurements out on the Foilboard® GREEN rigid insulation panel, using the gridlines as a guide. Using a straight edge and a sharp blade/knife, cut the rigid panel to size (width ways will ensure less wastage).

Step 3

Use Foilboard® spacer blocks to maintain an airspace between the Foilboard® and the metal sheeting to increase insulation performance.

Step 4

Fasten the insulation panel to the roof batterns/purlins with Foilboard® fasteners using approx. 5-6  per m2. Use either a hammer or a drill as required.

Step 5

Tape any penetrations joints and gaps using Foilboard® GREEN tape minimise hot/cold air transfer.

Required to install

Use Foilboard® Ultra Fasteners for GREEN 20 and GREEN 25.

(Use Timber or Steel fasteners depending on application)

Foilboard ® Tips

  • Foilboard® Panels don't need to join on a batten or purlin. Butt join and tape to ensure continuous insulation.
  • Install Foilboard® silver side as the finish to brighten your shed or garage space.
  • Place the fastener 50mm in from the edge of the insulation panel to leave room for the tape.
  • Off cuts can be used as a spacer block to help minimise wastage
