Need insulation? Why Earthwool Glasswool?

In New Zealand we are spoiled for options when it comes to insulation brands to pick from.

Knauf Earthwool is one of the most modern brands on the market, and is the only major insulation brand which is not manufactured locally. Earthwool is in fact made all over the world, and the New Zealand insulation is sourced directly from England and USA.

It looks and feels different to other brands. In fact, many customers who are using this superb product for the first time can’t believe that it’s actually made from glasswool. Don’t just take our word for it – try it out!

Many countries around the world, experience colder climates than ours, year by year. This maybe the reason, it adapts very well to the New Zealand climate in almost every situation. You may live in an old villa with matai flooring and 4 metre ceilings in Queenstown, or a small flat in a warmer area like Tauranga, every region has different heating and cooling requirements and Earthwool glasswool range has the product to suit almost every situation.

Earthwool uses renewable materials with technological advances

Knauf Insulation has invested heavily in new “ECOSE” technology to bring the itch factor, which for decades has been synonymous with glasswool, to an unprecedented new low.

Like many types of glasswool, Knauf Earthwool is manufactured using recycled glass bottles and has been ranked even more environmentally friendly than real sheep’s wool, according to the U.K’s Green Guide for Specification.

The product benefits from a unique binder which includes zero formaldehyde and is founded on renewable bio-based materials instead of old-fashioned petroleum-based chemicals.

Knauf Earthwool – Distinctive new Look and Feel

Earthwool insulation is a natural shade of earthy brown, and has no added dyes, bleaches or fake colours.

Furthermore it is less dusty and has a much softer and friendlier feel. As there is no formaldehyde or phenol used in the manufacturing process for Knauf Earthwool it improves the indoor air quality of buildings where these products are installed (compared to conventional glasswool products).

One of the secrets behind the absence of itch is the longer strands of insulation and the unique binders holding them together. The longer the strands, the fewer strands there are – and less strands of glasswool means fewer of those minute, protruding ends which are the cause of the well known ‘itch’ you may have experienced on the inside of your wrists when working with alternative brands of glasswool insulation. Compressed for ease of freight, storage and in most cases, dollar savings.

Don’t be fooled by the size of a bag of Knauf Earthwool – a single bag of R1.5/580mm will cover over 30m2 of wall area, which is almost double other brands of insulation. In most cases -depending on the size of your home, and product chosen, these coverages, per bag, may reduce the amount of product required to purchase which will reduce costs overall if you are building a new home or renovating an existing one.
