Insulation Tips
Pink Batts vs Earthwool
Aug
So which house insulation material is actually better, when you compare Pink Batts vs Earthwool? Well that may depend on what’s most important to you. Pink Batts comes with a “life time guarantee” and Earthwool comes with a standard 50 year guarantee, which in practice means you can expect the insulation to last as long as your home.
Pink Batts vs Earthwool – Which is the Better Batt?
First let’s look at the similarities. Both Pink Batts and Earthwool are both “glasswool” insulation, and the batts are in large part made from sand and recycled glass bottles. Both Pink Batts and Earthwool insulation batts are available in a variety of “R-values” to suit different climates. When making the insulation comparison PinkBatts vs Earthwool it’s important to realise that once the insulation is installed, the thermal benefit is practically the same. So an R2.0 wall insulation batt will give you the same thermal protection, regardless of whether it is branded Pink Batts, or Earthwool, or any other brand for that matter

Compare Insulation: Ease of Storage and Handling
Among all the home insulation types, Earthwool Insulation has gained popularity in recent years primarily for two reasons. Firstly, it uses a different binder, which makes it less itchy to work with. This is a real plus for DIY home renovators, not to mention professional installers who work with insulation on a daily basis. Secondly, Earthwool comes in a highly compressed packaging, which can significantly reduce the need for on site storage space, and also help to reduce freight costs if you’re paying the full cost to get the insulation delivered to your home or on site.
Low R-Value Wall Insulation: Pink = Firmer Fit
When looking for the best wall insulation, an often overlooked factor when choosing a brand, is how well the insulation batt will ‘stand’ in the wall cavity. The fact of the matter is, that even though in an ideal world, the wall studs will be spaced so exactly that they provide just the right amount of friction to the keep the insulation batts in their place, without folding or sagging – often the reality is somewhat different.
As any experienced insulation installer will know, a too narrow gap isn’t too much of a problem to deal with – you simply trim the edge of the insulation down to the required width. However a gap which is a faction to wide, can be a real “spanner in the works” – as without the necessary friction between the outside edges of the batt and inside edges of the walls studs, the wall batts can easily begin to sag. Here Pink Batts by Fletcher Insulation have a clear edge over it’s rival Earthwool, with it’s more rigid consistency making it easier to install.
Update: Knauf Insulation has recently announced an improvement in the consistency of the R1.5 wall batts. Is Earthwool now the best insulation for walls? If you’ve recently worked with either of these products, leave a comment and tell us what you think.
No smell? Best ceiling insulation based on odour (less) factor
If you’re old enough to remember the insulation being installed in the ‘old days’ you’ll remember the smell associated all roof insulation products. The longer the insulation lay there, the worse the smell, no doubt exacerbated by any number of vermin who have chosen to take refuge in the roof-space. Knauf genuinely claims that Earthwool is a better insulation as it has practically no smell, and the truth is that this is a fairly accurate statement. It smells like nothing, whereas most other glasswool products seem to have retained at least some of the odour, usually only noticeable in confined spaces. No doubt we will see more and more insulation brands setting their sights on an ‘odourless’ product range in the future. So if the no-smell factor is important to you, then the best home insulation for your roof may be Earthwool.
Our verdict – Pink Batts vs Earthwool
We recommend both of these high quality brands, as well as Bradford Insulation. Price is obviously a key consideration, so we recommend you calculate carefully the full cost of buying the insulation and getting it delivered to you, and then make an informed decision on what is the best insulation for you and your project.

It sounds like Earthwool insulation is a great choice. Just the fact that it is less itchy than the pink roll is a huge plus. I remember when we put in our insulation years ago, and the pink stuff made us all itchy for a week!
Which should I have installed – Pink Batts, Gold Batts or Knauf earthwool??
Hi Tish,
These are all high quality insulation products. If you have installed one of these three major brands according to the guidelines (ie. no gaps between batts), then should be seeing good improvement in the thermal performance of your home.

A question – is it better to insulate the ceiling first before doing underfloor?
Hi Tony,
Thank you for your question!
According to “Your Home“, 25%-35% of heat loss and heat gains passes through the roof, whereas only 10%-20% passes through the underfloor. So our recommendation would be to insulate the ceilings first.
Hope that helps!
As a professional installer, Earthwool is by far my preferred Insulation, the lack of itch is the main plus combined with more compact bags making transport much easier.
Thanks for your feedback Justin!
A wise handyman mentioned to me that if you rub talcum powder over exposed skin prior to working with insulation batts it helps reduce / eliminate itch.
Is it true that Earthwool uses a sugar binder that attracts termites?
Hi Sophia,
Earthwool uses a natural binder, but it does not attract vermin etc.
Useful information – however I think this article is due an update given product line are always evolving
I’d love to do the insulation myself but have phobia re certain things involved therefore need someone to install . What is the correct procedure if I’m paying someone please ie should they be expected to clean ceiling area they lay batts on first . And what’s the protocol re lights I have led down lights
Thanks
Hi K,
If your existing insulation is in bad condition then it is better to remove it so that you can get a nice finish, otherwise installing on top is fine.
For LED lights you need to leave a 50mm gap, and for other types of lights you need to leave a 100mm gap. Make sure that the transformer is placed on top of the insulation.
We offer a professional insulation removal and install service in Melbourne and Sydney. Please click here for more details.

What would be the best roof insulation for Perth please?
Hi Lia,
We recommend both Earthwool and Pink Batts in Perth, so it really comes down to your personal preference. The main thing that you need to consider is the insulation R-value as this will determine how much heat can pass through the ceiling. For an existing home we would recommend R4.0 or higher.
Cheers,

Hi
Looking to install roof insulation of R3.5 or R4.1 in our single storey house.
– Whats a recommended R rating for Brisbane? Is the cost justifiable going higher than R3.5?
– Can you recommend any installers in Brisbane?
Thanks in advance.
Hi Guru,
Thank you for your question. We recommend installing R4.0 roof insulation in Brisbane and we discuss why in this video: https://www.youtube.com/watch?v=0qc4CliDuLo. If you give our team a call on 1300 729 639 they may be able to help you find an installer in Brisbane.
Cheers!
I’m on the top floor of 3 storey flats with no insulation and its like a hot box. What roof insulation would you recommend for my situation and how many R’s.
Hi Colette,
Thank you for your question. We generally recommend a minimum of R4.0 roof insulation, however if you live in Melbourne, Sydney or Adelaide then we would recommend upgrading to R5.0 or R6.0 ceiling insulation. You can watch our video about R-values here: https://www.youtube.com/watch?v=0qc4CliDuLo
Cheers!

Hi I live in Tasmania and have a 60s house. It has loose full looking insulation that’s in pretty good condition. Could we lay over the top? And what R rating do you recommend please?
Hi Florence,
Thank you for your question. We have an article about topping up existing insulation here: https://pricewiseinsulation.com.au/blog/topping-up-insulation/. We would recommend aiming for a total of R6.0 insulation in Tasmania, due to the cool climate. It is difficult to know what R-value your blow-in insulation is providing, but you could probably top up the roof with R5.0 insulation batts. Feel free to give our team a call on 1300 729 639 if you have any questions.
Cheers, Pricewise Insulation
Hi, I have a single story pitched tile roof, live in Sydney, and want to install the best batts for both thermal and noise insulation. The house has roof sarking and ventilators, but no pre-existing insulation. I also want to avoid anything that causes skin irritations. What would you recommend?
Hi Paul,
Thank you for your question. If you are looking for something with both thermal and acoustic benefits, then we would recommend an R4.0, R5.0 or R6.0 ceiling product. If you are looking for a low itch product then we recommend Knauf Earthwool Ceiling Insulation. Feel free to contact our team on 1300 729 639 if you have any further questions. Cheers!
Hi, what types of baths would you recommend for a low, metal roofed home on the Coast of Qld? High humidity in summer and cold in winter. Please recommend the rating required. Thankyou
Hi Margaret,
Thanks for your question. We generally recommend R4.0 roof insulation in Queensland, however you would need to check how much clearance there is in your roof space considering that it is flat. Feel free to give our team a call on 1300 729 639 to discuss your project further with them.
Cheers!
Hi we are looking at updating our ceiling insulation as it’s only R2 at best for either hi performance gold R5 or knaff earth wool R5.
Hi Robyn,
It is a great idea to add another layer of insulation on top of your existing batts (providing they are in OK condition). Both the R5.0 Hi-Performance Bradford Gold Insulation and R5.0 Knauf Earthwool Ceiling Insulation Batts will provide the same level of thermal performance. We generally recommend the Earthwool Insulation because it is less itchy to install. Feel free to give our team a call on 1300 729 639 if you have any questions.
Cheers!
Hi,
Please note the manufacturer’s warranty isn’t on the thermal performance of the batt, just that it will remain a batt.
The firmest (and often itchiest) batts are actually the ones most likely to control the air pockets within and maintain their R value longer.
Hi Brett,
We agree that high-density insulation batts are a great option. Thankfully Knauf has managed to achieve densities of up to 32kg/m3 with their Ecose binder, while still remaining relatively low-itch.
Cheers,
Christa
Hi,
i’m looking for the highest soundproofing qualities for a between floor ceiling cavity to reduce the sound from upstairs to downstairs. I was looking at the earthwool soundshield plus, but relised this was for walls. are these ok for ceilings as well, or is there an equivalent for ceilings i should be using?
cheeers
Dave
Hi Dave,
Thanks for your question. The product we recommend for between floors is R4.0HD Earthwool Sound Shield Insulation, which is 140mm thick. Even though it is classed as a wall batt, it can certainly be used in ceiling spaces. We’ve got a YouTube video on the difference between wall and ceiling insulation here.
You can also check out our blog post about installing insulation between floors here.
Please do not hesitate to contact our team on 1300 729 639 if you have any questions.

Installing extra insulation – its getting hot in here!
I have a 2-storey home with cement tiled roof (23 years old). The current insulation is R2.5 and looks like it is good condition. What R value would you recommend I install over the top of the existing batts? I live on the Gold Coast and it does fell hot on the second level in the heat of summer. Thanks G
Hi Gary,
Thank you for your question. If the existing R2.5 roof insulation is in good condition, then we’d recommend topping it up with a layer of R4.0 insulation batts. This should be sufficient for your climate on the Gold Coast. However, you could also considering upgrading to R5.0 insulation. We’ve got a YouTube video about this here: ‘What to Check Before Buying Roof Insulation in Australia‘.
Please don’t hesitate to give our team a call on 1300 729 639 or email sales@pricewise.com.au if you have any further questions.
