Autex GreenStuf – Discerning Insulation Customers

We are often posed with the question – why would anyone pay more for GreenStuf? Does it do a better job of insulating the house?

The thermal insulating effectiveness of Autex GreenStuf is, like all the glasswool brands, measured by it’s R-Value. An R2.0 GreenStuf will restrict the same amount of temperature transfer as an R2.0 glasswool. After years of selling this increasingly popular product, we find that there are three primary reasons why some customers will opt for GreenStuf and will not hesitate to pay the extra cost of installing insulation for this premium polyester product:

Respiratory health issues

Households who have severe allergy or asthma issues in the home, will often prefer to take any possible steps to minimise any exposure to dust in the home environment. Since GreenStuf doesn’t have contain breathable fibres, that’s a big incentive for some families to purchase this product.

Plans to use ceiling area for storage or other purposes

GreenStuf is a clean and green, pleasant in appearance and totally itch-free. Some customers who have purchased Autex GreenStuf for their ceiling have told us that they intend to use their ceiling/loft area for regular storage, and that they preferred (each time they were to access this area) to be exposed to GreenStuff, rather than one of the glasswool products. In fact in any exposed settings, such as internal exposed garage walls – GreenStuf can be an excellent option.

Negative experience with old-style glasswool

There’s no doubt that many building professionals who worked with insulation in earlier decades have developed a permanent dislike for glasswool, and this is hardly surprising considering some of the nasty products which have been sold and used on the market in the past. They want relief and certainty that they will be installing an insulation nothing like the one they worked with in the old days, and when they purchase GreenStuf, they are guaranteed just that!

Note: While Autex’s insulation products are sometimes referred to as polyester insulation batts or green insulation batts, this is technically not correct. The correct terminology for Autex GreenStuf insulation products is rolls and segments.
