No certified insulation brand is better than the other – it all comes down to the R-value. Each of the brands we sell meet the Australian Standard AS\/NZS 4859. Australia is divided into a number of climate zones which help determine which insulation is best for each region. In the hot climates up north, properly installed reflective foil insulation is as important as bulk insulation products such as glass wool or polyester.\u003c\/p\u003e\u003ch3\u003eR2.5 Ceiling Insulation Application\u003c\/h3\u003e\u003cp\u003eSome ceilings, in particular flat pitched roofs, are almost impossible to insulate after plaster – there is simply not enough room to manoeuvre in the roof space. The usual solution is to install the insulation from underneath in between all the joists, before the plaster is installed. This can seem a daunting prospect, and you may well be better off hiring a professional installer to do it for you.

Depending on the spacing between the joists, you may need to cut some batts to size.

Polymax Ceiling Insulation is manufactured without the use of added chemical or resin binders. No water or ozone-depleting gases are used in the manufacture of Polymax.
