Description

R4.0 Earthwool Ceiling Insulation

The Knauf Insulation range includes some of the most popular products specifically designed for ceiling insulation. Since up to 35% of a home’s thermal energy can be lost through the ceiling or roof, this area should be the top priority in any insulation project.

Knauf Earthwool Ceiling Batts are available in a variety of widths and thicknesses to suit common joist heights and spacings. The R4.0 Earthwool Insulation Batts come in compressed packs for easier handling and transport.

Planning to install ceiling insulation yourself? Be sure to check out Knauf’s DIY installation videos before you get started. Earthwool Ceiling Batts are an excellent choice for DIY homeowners looking to reduce their energy bills while improving comfort.

Comfortable to Install

There are many home insulation options on the market, but Knauf Insulation stands out for its ease of delivery and installation. Earthwool Ceiling Insulation Batts offer a cost-effective thermal solution with the added benefit of acoustic (sound-deadening) properties. They are ideal for use in timber and metal frame residential structures.

For added peace of mind, all Earthwool Ceiling Insulation Batts are odourless, non-combustible, rot-proof, and non-hygroscopic (they won’t absorb airborne moisture). They do not attract vermin and will not support the growth of mould, fungi, or bacteria in your roof space.
