Earthwool Underfloor Insulation Batts

The Earthwool^® Underfloor Insulation 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.

The product is specifically designed for overhead installation in tight crawl spaces.

Earthwool Underfloor Insulation 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 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.

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 Underfloor Insulation 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 Underfloor Insulation Batts are packaged in a strong, white poly bag that offers excellent protection from abuse, dust and moisture.
Earthwool Underfloor Insulation Batt packages feature easy to follow installation instructions.
MasterBag 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.
