Why Earthwool Glasswool Insulation?
Knauf’s range of Earthwool Glasswool insulation is gaining popularity all over New Zealand wide with both commercial builders, home builders and DIY renovators. Earthwool insulation has two notable benefits:
1. Less itchy than other common brands of glasswool insulation
2. Compression packaged – more m2 coverage per bag means less storage space and handling required and it’s also cheaper to transport.
Modern day glasswool insulation has improved significantly compared to what was commonly installed some decades ago. Earthwool Glasswool ceiling insulation, external wall insulation, acoustic and underfloor insulation segments and rolls are recommended for Christchurch and all the surrounding suburbs.
What R rating for the Christchurch area?
Christchurch has a temperate climate, but overnight frost is common in winter. This should be taken into account when deciding which insulation R-Value to go with. New homes will generally be specified as requiring a certain minimal R-value to meet energy efficiency requirements. If you’re doing a minor renovation or adding insulation in an old house, we would usually recommend a minimum R2.0 in the walls and R4.0 in the ceilings. An adequate layer of thermal insulation will keep your house cooler in summer and warmer in winter, and noticeably reduce the load on any heating and cooling appliances.
