Should I Choose Earthwool wall insulation or Bradford wall insulation?

Knauf-Earthwool-Insulation-Logobradford-insulation-logoNowadays in modern building construction, wall Insulation plays a vital role to advance the living environments for people and lessen energy efficiency costs. In this blog, we will discuss the best product for wall insulation. Insulation for your office, house helps reduce your electricity cost, and it regulates the room temperature.

Which one is better?

First look at the similarities, both the Earthwool and Bradford wall insulation is an environment-friendly and advanced generation of highly sustainable and soft wall insulation that made from Glasswool. Glasswool made from sand, and recycled glass bound with a binding agent to create incredibly useful insulation material.

Bradford wall insulations are Australian made to meet the Australian standards while Earthwool is a trade name for Knauf insulation usually manufactured in USA, Russia or Germany.

While considering the similarities, Earthwool and Bradford wall insulation both hold and absorb practically no moisture from the air around it and have non-combustible properties act as an effective barrier to heat transfer. Both are available in a variety of R-values (measuring tool to rate the level of thermal resistance) to suit different climates. So, it’s imperative to realize that R2.0 wall insulation will give you the equal thermal benefits no matter which the brand is. The Earthwool  insulation comes with a standard 50-years guarantee, and Bradford wall insulation comes with a 70-year warranty, which means you can imagine the insulation to last as long as your home.

Earthwool wall insulation has grown popularity in recent years for two reasons. Firstly, Earthwool comes in extremely compressed packaging, which can reduce the need for a cost to get the insulation to transport at your home. Secondly, Earthwool uses a kind of binder that makes it less itchy to work with. A plus point for all the DIY renovators.

Both the Bradford and Earthwool wall insulation has a soundproof quality, well not exactly quiet, it limits the sound transmission from one room to another and reduces unwanted outdoor noise thus work as an acoustical barrier for energy-efficient construction. While Bradford also provides this feature in Bradford sunscreen product (chiefly made for noise reduction).

Now comes the question, if Earthwool made from wool? No, it’s not, Earthwool manufactured from sand, recycled glass bottles and other materials bonded by ECOSE Technology, a revolutionary new binder based on bio-based materials rather than the petroleum-based chemicals and contains no acrylics, phenol, formaldehyde, or artificial colors.

Let’s compare the features and benefits:



  • Maximum savings on cooling and heating energy costs
  • Easy to install.
  • 100% Bio Soluble, posing no risk to health
  • Low irritant and low allergen
  • Stiffened explicitly for use in wall applications
  • 70-year warranty
  • High recycled content up to 65%
  • Reduces greenhouse gas emissions.
  • Fire resistance.
  • Will not settles over time


  • Softer feel for easier handling
  • Higher density and thickness for outstanding thermal performance
  • Improved comfort
  • Meets the highest Australian insulation standards
  • It does not emit any smell of chemical.
  • Easier to install.
  • Super soft and itch-free material thus leading to easy installation.
  • Earthwool  absorbs less dust.
  • It is recyclable.
  • It has no added colors thus proving to be safe to use.
  • Warranty of 50 years
  • Made using recycled glass or sand
  • No added formaldehyde
  • Absorb sound
  • Non-combustible and thermally efficient.
  • Reduces energy bills
  • Compression packed – more product per pack
  • Increased durability and comfort in building
  • odorless



Ranges and thickness:

Earthwool wall insulations are available in 75mm, 90mm, and 140mm thicknesses. While Bradford wall insulation  available in 75mm and 90mm width only.

How Itchy is Glasswool Insulation?

Glasswool insulation manufacturers have taken a long journey in developing safe, comfortable and clean products. Bradford now incorporates Arlanda soft fiber technology (a technology that creates fiber more delicate to touch). While Earthwool is the most delicate and least ‘itchy.’ This is because the fibers are softer and longer, making less ‘ends’ to irritate.

Wall products:

Earthwool is available in external wall insulation (chiefly focused on thermal control) and internal wall insulation (mainly concentrated on acoustic power). While Bradford has won the race here as it is available in various products like, Bradford black wall insulation (primarily designed for allergy and asthma sufferers), Bradford Hi-performance wall insulation (designed for optimal performance in exterior cavity walls), and Bradford polymax wall insulation (designed to reduce energy bills and maximize comfort).


Both have been very renown products use for wall insulation these days. We recommend Earthwool insulation as the best and most comfortable to work with Glasswool insulation. We recommend you estimate carefully the full cost of purchasing the insulation and getting it delivered to you, as the price is an important consideration.
