FAQ
Frequently asked questions
Q: What R value is needed for ceiling insulation?
A: The performance of insulation is measured in terms of R Value, which stands for ‘Resistance Value’. For new builds check your Energy Rating for the R rating required. You can always go higher than specified but not lower. For existing homes, Learn More
Q: How much ceiling insulation do I need?
A: Often we find that, while many homeowners agree that insulation is important and they assume that they have some level of insulation in their ceiling, we rarely meet people who know exactly how much insulation they have overhead. Learn More
Q: What do I do about halogen downlights in my ceiling?
A: If your home is fitted with halogen down-lights, it is best to replace them prior to installing ceiling insulation so that the best possible ceiling coverage can be achieved. Aside from the fire risk and draught concerns associated with down-lights, LED downlights that are IC4 (IC standing for Insulation Contact) rated can be insulated over the top. Refer your electrician to Rule 4.5.2.3 of Australian Standard AS:NZ 3000.
Q: Can you lay insulation on top of old insulation?
A: If you have existing ceiling insulation, rest assured that it can remain in place. You should level out any existing loose-fill insulation, or fill in any gaps in your existing batts, before topping up with our high quality product to ensure the best thermal protection for your home.
Q: Can I return insulation?
A: No, all Polymax insulation is a made to order product and cannot be returned unless it is a warranty claim as described in the warranties terms and conditions. If you have insulation left over from your project, you will find a very buoyant market for it on social media.

Do I really need ceiling insulation?
Yes—ceiling insulation is one of the most effective ways to improve your home’s comfort and energy efficiency. Without it, your home can lose up to 35% of its heating and cooling through the roof and your home will never be truly comfortable.
What’s the best type of insulation for ceilings?
We recommend Polymax polyester batts. They’re soft, safe to handle, don’t itch, and are made in Australia. Plus, they’re durable, low allergen, and designed to last the life of your home (70 year warranty).
Can I install ceiling insulation myself or do I need a professional?
Yes—if you’re comfortable working safely in your roof space. DIY is possible with the right safety gear and guidance. We also have step-by-step videos to walk you through it. If not, you may prefer to hire a pro. Please contact us for a referral to a trusted installer in your area.
Will it actually save me money?
Absolutely. A well-insulated ceiling reduces how often you need to heat or cool your home, which means lower energy bills month after month.
Is it safe for my family?
Yes—Polymax insulation is non-toxic, contains no harmful chemicals, and won’t irritate skin or lungs. It’s a clean, safe choice for families, babies, and pets.
