Insulation Netting is used to support insulation between floor rafters or in vertical wall insulation. It can be installed easily by stapling or tacking to the rafters or vertical struts. The insulation net is allowed to sag between the rafters and will support a depth of insulation from 100mm to over 250mm. A single thickness of insulation Net can span rafters up to 450mm apart and a double thickness up to 1200mm. The net is made from UV stabilised polypropylene. Further to this, it is rot proof and chemically resistant.
