Earthwool R5.0 Ceiling Insulation Batts – 580mm Wide
Improve your home’s energy efficiency and comfort with Earthwool R5.0 Ceiling Insulation Batts, available in both 580mm width. Designed to suit Australian homes, these premium ceiling batts deliver exceptional thermal performance, making them ideal for both new builds and retrofits.
With a high R-value of 5.0, these batts offer outstanding resistance to heat flow. Therefore, they help keep your home cooler during summer and warmer throughout winter. As a result, you can reduce your heating and cooling costs while lowering your environmental impact.
In addition, Earthwool R5.0 batts are made with advanced ECOSE® Technology, which replaces harsh chemicals with a sustainable, bio-based binder. Consequently, the batts are softer to touch, odourless, and low in dust. This means installation is cleaner, safer, and more pleasant—whether you’re a professional installer or a DIY renovator.
Moreover, these batts do more than just regulate temperature. Thanks to their dense construction, they also offer effective acoustic control, helping to minimise noise transfer between floors and from outside. Thus, they contribute to a quieter and more comfortable living environment.
To suit a variety of ceiling joist configurations, the batts are available in both 580mm width for 600mm joist centres. This ensures a snug fit with minimal gaps or cutting, which improves performance and reduces waste.
