Earthwool External Wall Insulation Batts

Wall Plain Pack

Description

The Earthwool® External Wall Batt range is a new generation of softer, safer and more environmentally friendly glasswool insulation.

Advanced compression packaging reduces handling time and the risk of
damage in transit and on-site.

Although the product is primarily designed for use in external walls it can also be used for internal walls to reduce sound transmission from room to room. It is thermally efficient and cost effective in saving energy and providing increased comfort in buildings.

EarthWool BattsBatts are the traditional insulation product for insulating external walls and are available in thicknesses to suit 75mm, 90mm and 140mm timber and metal frames. Unlike reflective foil, Earthwool External Wall Batts prevent heat gain in summer and heat loss in winter by countering convection, conduction and radiation.

Knauf Insulation also offers High Density (HD) and Super High Density (SHD) External Wall Batts with increased density and lower thermal conductivity to maximise energy savings.

DriTherm®, a silicon impregnated insulation product, is also available for double brick walls.

Earthwool External Wall Insulation Batts are available at your local Bunnings Warehouse.

If you're installing Earthwool yourself then don't forget to check out our DIY Safety Instructions and Precautions before you start.

 

 

Application

Earthwool External Wall Batts provide a cost-effective thermal and acoustic barrier for energy-efficient construction. The consistent quality, low dust, and clean-cutting resilient fibres make fabrication easy and installation fast. Earthwool Batts can be used in timber and metal frame applications in residential structures.

These applications include thermal and acoustic treatments to walls, ceilings and floors. Knauf Insulation offers Earthwool in a wide range of sizes and R-values. Earthwool insulation can be used for cavity walls, floors, ceilings, attics, basements and crawlspaces. It is highly resilient, recovering quickly to full thickness. It also greatly reduces the transmission of noise in the home.

ECOSE® Technology

Knauf Insulation mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.

The technology has been developed for Knauf Insulation's glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE Technology contain no dye or artificial colours - the colour is completely natural

Features

Proven Performance

  • Preferred by professional installers concerned with quality, appearance and  productivity.
  • Excellent acoustical properties reduce sound transmission in the home when  properly installed in walls, ceiling and floor systems.

Durability

  • Earthwool External Wall Batts are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Superior Handling

  • Highly resilient insulation recovers quickly to full thickness for a snug fit and superior finished aesthetics.
  • Consistent quality materials feel good, cut easily and install fast. 
  • Low dust for easier handling and increased productivity.

Convenient Packaging, Easier Handling

  • Earthwool External Wall Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
  • Earthwool External Wall Batts packages feature easy to follow installation instructions.
  • Master bag batt units (containing multiple packs) ensure reduced handling costs  with improved compression – more square metres per bag, more square metres  per truck load, fewer trips to the job site and less warehouse space for storage.

Superior Service and Support

  • Knauf Insulation is totally focused on providing first class customer service, producing high quality product and ‘on time in full’ deliveries. 
  • Knauf Insulation recognises the need to establish, develop and support a professional network of distributors and re-sellers in order to service a growing insulation market.
