Permastop Building Blanket  from Fletcher Insulation



Fletcher             Fletcher Insulation Blanket

Permastop® Building Blanket is ideal for use under metal roofs to provide thermal and acoustic comfort and condensation control. Permastop® reduces the amount of heat entering your attic space working in tandem with ceiling insulation.

Permastop® Building Blanket is an insulation blanket that is fixed directly under the metal roof and is effective in reducing the noise levels entering your home from rain, hail, aircraft and other outside noises. 75mm Permastop® Building Blanket can reduce sound transmission through the roof by up to 18dB.

Permastop® Building Blanket is lightweight, flexible insulation blanket faced on one side with Sisalation® reflective foil laminate (Light, Medium or Heavy Duty.) This combination acts as an effective barrier against condensation forming on the underside of your metal roof. When warm, moist air is vented into the roof space from bathroom and kitchen fans and vented range hoods.

Fletcher Insulation Sarking

Fletcher Insulation Sarking

Sisalation® Tiled Roof Heavy Duty (466) is designed for use in demanding applications that require extra resistance to puncture and tearing, particularly as a result of traffic that is common during installation of roof tiles. The polymer coating provides excellent resistance to high humidity and salt laden air making the product ideal for coastal regions.

Air-Cell Glareshield

Kingspan Air-Cell Glareshield® is a patented thermo reflective anti-glare insulation designed to combat heat gain and heat loss in all three forms (radiation, convection and conduction), resulting in thermal performance superior to many conventional insulations. Kingspan Air-Cell Glareshield® is non-allergenic, non-irritant and has none of the health and safety warnings associated with using many conventional bulk insulations.

Kingspan Air-Cell Glareshield® is suitable for:

  • Roof Insulation- Residential Tiled Roof, Residential Metal Roof, Commercial Metal Deck Roof

Air-Cell Insulbreak

Kingspan Air-Cell Insulbreak® is a 3-in-1 insulation, vapour barrier and thermal break solution for steel-framed construction. In steel-framed buildings Kingspan Air-Cell Insulbreak® delivers the R0.20 thermal break required for BCA compliance*, reducing thermal bridging and conductivity between building elements. Kingspan Air-Cell Insulbreak® is also commonly used in non-steel framed applications such as timber framed roofs.

Kingspan Air-Cell Insulbreak® is manufactured with a cross-linked, closed-cell foam structure, and sandwiched by highly reflective foil surfaces.

* Refer BCA Vol. 1 Section J 1.3(d), 1.5(e); Vol. 2,
Kingspan Air-Cell Insulbreak® is suitable for:
  • Roof Insulation- Residential Metal Roof, Commercial Metal Deck Roof
  • Wall Insulation- Stud Frame Wall, Warehouse Metal Clad Wall

Air-Cell Permishield

Kingspan Air-Cell Permishield® is a vapour-permeable barrier and insulation wrapped up in a single product. Kingspan Air-Cell Permishield® is designed specifically for steel-framed wall applications for use behind lightweight cladding materials that require vapour permeance.

Manufactured with a patented closed-cell structure sandwiched by highly reflective foil surfaces and pierced with tiny, evenly-spaced breather holes, Kingspan Air-Cell Permishield®
allows building professionals to do away with the traditional sarking-plus-batts combination in order to achieve thermal compliance as well as satisfy vapour permeance.

Kingspan Air-Cell Permishield® issuitable for:

  • Wall Insulation- Stud Frame Wall, Reverse Brick Veneer Wall
