The Earthwool® Ceiling Insulation Batt range is a new generation of softer, safer and more environmentally friendly glasswool insulation for your home.

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

Batts are the traditional insulation product for ceilings, supplied in pre-cut rectangles at either 430mm or 580mm widths to suit the most common ceiling joist centres.

Earthwool Ceiling Insulation Batts are recommended for installation from either below ceiling joists (i.e. within the room) or from above ceiling joists (i.e. within the ceiling space).

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

Earthwool Ceiling 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 Insulation 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.
