Pink Batts vs Earthwool Insulation. Which insulation brand is best?

So which product is actually better, when you compare Pink Batts vs Earthwool? Well that may depend on what’s most important to you.

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.

The pink insulation 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.

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.

Update: 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.

    I like that you mentioned the earthwool insulation is less itchy. I’ve worked several times with other types of insulation and really react to the fiberglass. Hopefully, it will also be a little easier and quicker to install.

    • 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.

  2. Ridley Fitzgerald says:

    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!

  3. Frank says:

    Pink Batts VS Earthwool is a no brainer, I would vote Earthwool for the smell (or lack of smell) alone. The new Pink Batts are better than the old stuff but they haven’t managed to get rid of the smell. Plus Earthwool hardly itches at all at least if you were long sleeves

      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.

      Please don’t hesitate to contact us on 1300 729 639 if you have any more questions.

    • Pricewise Insulation says:

      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.
