R5.0 Earthwool Ceiling Insulation
Earthwool Insulation is available in a range of widths and thicknesses to suit the most common joist heights and spacings. Knauf Earthwool ceiling insulation batts—individual rectangular segments of insulation—are supplied in compressed packs for easier transport and quicker handling. The R-Value and corresponding thickness of each batt determine the number of batts included per pack.
Knauf Ceiling Insulation Batts are packaged in durable poly bags, which also include basic installation instructions. If you plan to install the ceiling insulation yourself, be sure to review Knauf’s DIY Safety Instructions and Precautions beforehand. This insulation is an excellent choice for DIY homeowners looking to reduce their energy costs and improve home comfort.
Cost effective delivery and easy installation
Among the many home insulation options available, Knauf Insulation Batts stand out for their ease of delivery and installation. Knauf Earthwool Ceiling Insulation Batts offer a cost-effective thermal and acoustic solution, suitable for both timber and metal frame applications in residential buildings. In addition to improving energy efficiency, they also help reduce noise transmission within the home.
Earthwool Ceiling Insulation Batts are odourless, non-combustible, rot-proof, and non-hygroscopic (they do not absorb airborne moisture). They do not attract vermin and will not promote the growth of mould, fungi, or harmful bacteria, making them a safe and reliable choice for any home.
