The Goldilocks Effect.
Not too hot, not too cold; just right.
It's easy to forget that your home should be your escape and paradise. Cool in the summer, warm in the winter, and not reliant on power-hungry heating and cooling to get it to the right temperature. Ceiling insulation is the best investment you can make for your home to providing year round comfort. Your ceiling and roof is your largest culprit for heat transfer, so it makes sense it have adequate ceiling insulation.
There are dozens of ceiling insulation materials and brands on the market, so it's important to choose not only the right product, but the right thickness for your home.
95% of what is on the market now is recycled glass, better known as fibreglass insulation. Brands like Bradford Gold, Bradford Gold HI Performance, Fletchers Pink Batts, Knauff Earthwool and Termico are all variations of fibreglass batts and supply over 90% of the Australian market. The advantage of fibreglass insulation, ceiling batts and wall batts is it's long life span and it's fire resistance. Unlike issues that previously arouse around fibreglass, the fibres are not loose and will typically not cause any irritation. We recommend the Bradford Gold range of glasswool insulation as it is Australian made, comes with a 70 year warranty and is the only product approved by the Australian Asthma Foundation.
Just like your quilt or pillow, polyester is a common ceiling insulation and wall insulation product. Polyester is perfect for allergen sufferers, being low-allergen and VOC free. When compared to the fibreglass insulation, it does not go higher than an R4.0 rated batt and is more expensive than fibreglass, but is perfect for allergen suffers and provides better acoustic dampening properties. We commonly install the Bradford Polymax range, as well as the AuTex GreenStuf. The Polymax is made from 80% recycled materials and has zero wastage, coupled with being made local in Perth, our preferred supplier for all things polyester ceiling insulation.
One of the oldest insulation materials, wool has traditionally been used from garments to housing to insulate. Being one of the most natural materials for ceiling insulation, it is not only environmentally responsible but can also claim to have Zero Ozone Depleting Potential. With low allergens and VOC similar to polyester, wool has become highly sought after as an insulator for homes across Australia (it also helps we have plenty of sheep). It's important when looking at wool, that your comparing real wool with other products. Brands like 'Earthwool' are not actually wool products, being made up predominantly of fibreglass and likewise there are a lot of wool/polyester blends available on the market. Available in a high range of R values similar to fibreglass, it is important to consider the draw backs associated with this sustainable product. Most real wool ceiling insulation needs to be treated with a fire resistant chemical which can be an irritant. If wet, most wool insulation needs to be replaced and being organic, we have seen a few Perth homes become infested with rodents and black beetles.
