Pink Batts vs Earthwool

Pink Batts vs Earthwool Insulation Comparison

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 Pink Batts 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 has a clear edge over it’s rival Earthwool, with it’s more rigid consistency making it easier to install.

Update: Knauf 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.

    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!

      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.

      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.

  3. Peter Nieborak says:

    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.

    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

    • Pricewise Insulation says:

      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.

    I’m converting a van into a camper an. What insulation products would you recommend for the ceiling, walls and floor?

    • Pricewise Insulation says:

      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.
