Often times, homeowners seek short-term solutions to fix a cold, damp house – running heat pumps, dehumidifiers and similar devices – when the best solution is the one that addresses the fundamental problem of heat escaping. Having a well-insulated home keeps you and your family healthier, as well as saves you money every year. The World Health Organisation recommends temperatures between 18 °C and 22 °C, and this is especially important for vulnerable groups such as children and the elderly. A Statistics New Zealand Report on Energy and Hardship showed that up to a third of New Zealand households struggled with their power bills or spent a large part of their income on power. This ends up costing more in the long run due to incurred health-related costs. A recent MOTU report demonstrates that the return on investment from putting good quality insulation in a home is five dollars for every one dollar invested. The Warm Up New Zealand: Heat Smart programme found that retrofitting homes with insulation produced several healthrelated savings and benefits of up to $860 per year per household, including: • Reductions in GP visits • Reductions in time off work and school • Reduced household level hospitalisation costs • Pharmaceutical use costs • Reduced mortality risk for the elderly. The study also estimates at least a third of private dwellings may be under-insulated, and it suggests that if all homes were properly insulated, New Zealand might gain ongoing health-related benefits of approximately $0.5 billion per year. Not only that, but it shows that retrofitting insulation and installing effective home heating decreased wheezing in children with asthma and reduced number of sick days off school. 78 | B&C - Issue #128
Current insulation regulations for rental homes It’s been compulsory for all rental homes to have ceiling and underfloor insulation since the 1st of July 2019. All rental homes also must be fully compliant with the Healthy Homes Standard by 2024. All rental properties covered by the Residential Tenancies Act need to meet the new regulations, and insulation must meet the correct standards and be installed safely. Wall insulation isn’t mandatory. Landlords beware: if you don’t have the correct insulation installed, you can be in for a big fine. You may be liable for exemplary damages of up to $4,000. Checking with a professional is crucial to see if you’re in compliance, an exception or are in breach of the Residential Tenancies Act.
Building for climate change Probably one of the biggest impacts insulation can have is around New Zealand’s carbon zero targets and effecting positive climate change. The Insulation Association of New Zealand fully supports the recent report released by the Building for Climate Change Commission and is encouraging the NZ Government to go further as we need to deal with all the existing housing stock. Engaging in a Government subsidies deep renovation programme has the potential to be the single biggest change towards achieving our climate change goals – which could be brought forward to 2030.

Questions to ask before starting work at a new site: • Has the property I am working on had any changes made to the roof over time? • Was the property re-roofed, partially damaged etc? • If so, what was the roof product replaced? If you don’t know what the roofing product is – especially if residue has been left on the insulation being replaced – get it tested before starting work. The two main areas of concern are: 1. Some blow-in types of insulation used in NZ in the past have contained asbestos. 2. Asbestos contamination from roofing such as super six and super eight sheeting. If there is any unknown blow-in type of insulation, it should be tested. If there is any uncertainty around the product, it should also be tested. IAONZ is aware of a blow-in product imported from Australia containing amosite asbestos – asbestos has also been found in old vermiculite blown insulation. Asbestos was contained in a lot of roofing material, as well as some exterior cladding material. Installers should never work in a ceiling with super six or super eight roofing. It’s shaped like corrugated iron, but it’s thicker and made fibrolite. The safety of you and your workers is absolutely vital. Ensuring you have the proper plan for if and when you encounter asbestos is important for everyone’s health and to stay compliant with the law.
