Even without any heating or cooling of the house, the temperature in the Ideal House will never fall below 20°C. And it’s the high level of insulation that makes this possible. The owners chose Earthwool® glasswool insulation from Knauf Insulation to provide the extra-high thermal performance and high R values required – R2.8 and R1.4 in a dual-skin timber frame that reduces thermal bridging, R5.2 for the ceiling and R2.8 in a floating floor system. Additionally, R4.1 was installed in the midfloor and R2.2 in all the internal walls for acoustic benefits. Earthwool glasswool insulation was also chosen for its Eurofin certification, which means the insulation is conducive to good indoor air quality, which was another key requirement. Made using recycled glass and sand, the glasswool is super soft, which makes it easy to install. It is also less itchy than many alternative products, and has no added formaldehyde, phenols, bleaches or dyes. Earthwool glasswool is the only glasswool insulation available in New Zealand with GreenTag Level A certification, which counted towards the high 8 Homestar design rating. Above left and top: An even temperature all year round – the interior of the Ideal House will naturally stay above 20°C through all seasons, due to the high level of insulation. Earthwool glasswool with high R values was installed in the walls, ceiling and underfloor. Above: Earthwool glasswool provides a super-soft insulation that is easy to install. It comes with a 50year warranty from Knauf Insulation. search | save | share at trendsideas.com 67
