Roof Insulation is a simple and effective way to reduce heat loss. Normally, roof insulation is effective for many years and it pays of itself in may ways. Some roof insulation products that can be used for residential or commercial structures are:
- Glasswool Batts:
Also known as Pink, Earthwool or Bradford. Glasswool is just another name for fibreglass insulation. It’s also sometimes referred to as glass fibre insulation or fibreglass batts. The result is millions of tiny air-pockets being created inside the insulation, which is what gives glasswool insulation its excellent insulating properties.Application: Ceiling and Walls
- Foil Insulation:
Also known as Sarking or Sisalation. Installing an additional layer within a roof that insulates or reflects heat is a pivotal addition to any residential or commercial structure. Roof sarking provides protection from mould growth and ceiling staining, limits dust and particles entering through the roof and even improves thermal performance by reducing heat flow.Application: Roof
- Foam Cell Insulation:
Also known as Permicav or Foam Cell, thermo reflective insulation, comprising a cross-linked, closed-cell foam core sandwiched with an anti-glare foil facing on one side and a plain foil facing on the other side. specifically designed to reduce the risk of condensation in walls with cavities, has improved vapour transmission.Application: Cavity Walls
- Building Blanket:
Also known as Permastop, Anticon or Permishied is a reflective insulation composite comprising of a glasswool blanket substrate that is faced on one side with a high quality Sisalation® reflective foil laminate, it is suitable for use in residential and commercial metal clad roof applications as well as metal clad walls. It provides excellent thermal and acoustic properties by reducing heat loads entering a building and minimising the internal reverberation and flow of unwanted nuisance noise generated from adjacent buildings/rooms and/or the external environment.Application: Roofing and Walls
- Polyester Batts:
Polyester insulation is a synthetic or man-made product based on petrochemicals. Some polyester products contain recycled plastic fibres, for example those from recycled plastic bottles.Application: Ceiling and Walls
It is possible to add insulation to all roof types common in Australia and, even if some effort is required to lift roofing, the benefits make it well worthwhile. Tiled roofs without sarking can have it added easily if the roof is being re-tiled. Metal roofs need a condensation barrier directly beneath them: a layer of reflective foil sarking is an effective membrane and a barrier to radiant heat, thus doing two jobs at once. It is usually necessary to remove the roofing to install it, but most metal roofing can be removed and reinstalled easily, without damage.
The ceiling space can also be insulated. Ceiling insulation is a barrier of material within your roof space and can either be laid between the joists. Insulation between the joists keeps warmth in your living space below and creates a cooler ceiling space. Other benefits of ceiling insulation include lower heating bills, reducing your home’s carbon footprint, improving its energy efficiency rating and increasing your home’s value.
