Autex Greenstuf | Polyester Roof and Ceiling Insulation Batts

Autex polyester insulation batts are one of the best forms of bulk insulation you can get. They keep their shape and tear to fit any size gap making them cost effective. (The performance of insulation is measured in terms of R-value, which stands for "Resistance Value.")

The Building Code of Australia requires a minimum value for new homes of R 3.5 in the Melbourne area and R 4.3 in colder areas of Victoria (excluding plasterboard rated at R 0.7).

In our lab, Autex roof and ceiling insulation batts have survived water, fire and compression testing, emerging with dimensions and durability intact.

We wanted to provide a ceiling insulation product that would stand the test of time, suit a wide range of applications – including cold Victorian winters - and reduce household energy bills. Autex polyester insulation delivers.

When this material is exposed to flame, it just melts. Water runs straight through it, allowing it to dry very quickly, retaining its form and bulk. If you sit on Autex roof insulation batts, they bounce right back to their original shape!

Some types of batts aren’t this resilient, which impact their R-value and make them less energy efficient. Autex poly insulation is super easy to install too.

When we chat to people who want to buy insulation, we often find they don’t know how much ceiling insulation they have, and what type it is. Many are unsure whether they have it at all.
The good news is, you can lay polyester ceiling batts from scratch, or use them in addition to your existing insulation.

In terms of insulation prices, poly batts offer terrific value for money. With thermally bonded fibres – no glues or nasty chemicals – this thermal insulation also helps protect your health while looking after the environment.

If you’re looking for green insulation, it’s a great choice. When it comes to durability, these Australian-made polyester batts feature a 50-yeardurability warranty on product performance when correctly installed.

Explore why you need ceiling insulation, and how to choose the best type of insulation.

Without effective insulation, you lose expensive heat through the ceiling in winter. In summer, your attic becomes a sauna, pushing unwanted heat down into your living spaces.

Autex roof and ceiling insulation comes in R-values of R2.5, R3.0, R3.5, R4.0 and R4.5, to suit your requirements. Note there is a 200m2 minimum order quantity for all Autex products. 

Important safety notes

1. Check switchboard for power and light safety switches, before entering roof.
2. Be aware of any exposed electrical junctions you find in the roof.
3. Never lay batts over electrical wiring.
4. You can only insulate over IC4 down lights. To insulation over your downlights, they MUST have IC4 rating showing on each downlight.
5. If your down lights are not rated IC4 you MUST ALLOW a non-insulated radius of 200mm around the down light around your down lights.

What you will need:

• Ladder (commercial or industrial grade)
• Knife/blade
• Drop sheet to protect carpet
• Flashlight/headlamp
• Face protection/mask to prevent dust
• Clothes you don't mind getting dirty
• Gloves
• Safety glasses
• Push stick (see video)

Hacks:

• Avoid laying batts in summer, when roof space becomes dangerously hot. If the roof space is hot limit your time to a maximum of 10 minutes at a time. Early mornings are more suitable if you want to install roof insulation in hot weather.
• Get someone to help you load material through the manhole.
• Load all batts before you start work, to minimise ladder use.
• Insulate manhole cover by measuring, tearing to size, and then gluing.
• Level any existing loose fill, before laying Autex batts on top.
• Tear sections of Autex batt to fill gaps before you start.
• Autex batts are easy to tear in one direction, and tough as boots in the other. In the vast majority of cases, they can be torn to fit any space. If you really need to cut in the ‘indestructible’ direction, use a long snap-blade knife, press hard and cut down several times.

Hacks for Draught Dodgers

• Can be fitted inside or outside door.
• Fit Draught Excluder before fitting Draught Dodgers.
• Where external doors open inward, fit Draught Dodgers on the outside.
• Where external doors open outwards, fit Draught Dodgers on the inside.
• Stain or paint the Draught Dodgers to merge seamlessly with existing door frame.
• Clean door jamb before you start, for optimum adhesion.

3. Polyester Insulation doesn't lose its loft or integrity over time and keeps its full thermal rating for life!

Q: What is the minimum R-value for ceiling insulation?
A: The Building Code of Australia 2012 specifies that ceiling insulation covers minimum R4.6 through to R5.1 in Melbourne and Sydney. In colder areas, R6.3 is the minimum. When you buy insulation we found the best practice is to get a higher than minimum R-rated ceiling batts to future-proof your insulation installation.

Q: How thick should my ceiling insulation be?
A: When it comes time to buy insulation for your ceiling, the thicker the better. Each product will measure differently, but the rule of thumb is that the thicker ceiling insulation is, the higher the thermal rating is, and the less energy you need to use to warm and cool your home.

Q: Is it better to insulate ceilings or walls?
A: The most effective form of home insulation is ceiling insulation, without it your home is not protected from the extremes of temperature. As you know, warm air rises, and we have found the best practice is to install ceiling insulation batts first and floor and wall insulation second.

Q: What is the best insulation for walls and ceilings?
A: During the last 20 years of installing and researching ceiling insulation the best product we have found is Polyester Insulation. Polyester Ceiling Insulation Batts are non allergenic, Hydrophobic and rodent resistant. They are made up of 80% Recycled materials and offer great thermal performance for a long lifetime.

Q: Why is a higher R-value needed in the ceilings?
A: As much as 45% of your home's heat will be lost via your ceiling as warm air rises. That's why it's very important to have high R-Value ceiling insulation installed in winter. Insulation is just as important to have in the summer too, when ceiling insulation batts are installed it creates a protective layer between you and the extreme heat in your roof space.

Q: Can you use wall insulation in the ceiling?
A: Yes, If your ceiling space is a little small, you can use multiple layers of Wall Insulation Batts instead. Polyester Insulation wall batts are available in a 90mm thick batt and may be the best insulation for your tight roof space.

Q: What are the differences between fibreglass and polyester insulation?

Heat bonded polyester insulation is:

1. Stronger and more durable than fibreglass
2. Free of chemicals that attract Rodents and Insects
3. Made up of 80% Recycled material
4. Non-allergenic
5. Does not cause itchy skin like glass fibres do
