Practical, plain-English advice on insulation and healthier homes — written for Hamilton and the Waikato.
Wall insulation

Most pre-1990s homes were built with nothing in the walls. Here’s how to tell — and what retrofitting actually involves.

Insulation

If you have noticed condensation on your windows, a persistent musty smell, or mould creeping along the corners of your ceilings, you are likely dealing with a damp house.

Insulation

Many older homes were built with little or no wall insulation. This can make them harder to heat in winter, hotter in summer, and less comfortable throughout the year.

Many garages in New Zealand homes have little or no insulation. They are often treated as storage areas or a place to park your car and sit outside the main thermal envelope of the house.

What’s insulation? Insulation is a material used in homes to slow the movement of heat. It helps keep warmth inside during winter and slows heat entering during summer.

With a wide range of insulation products available, it’s easy to feel unsure about which option is right for your home. Two of the most common choices in New Zealand homes are traditional batt insulation and blown insulation.

Older homes in New Zealand offer unique charm, but they often present challenges when it comes to keeping them warm, quiet, and energy efficient.

If your home feels warm and stuffy during summer, it could be due to poor insulation.  When the temperature rises outside, it often rises inside too, and this makes it harder to stay comfortable.

Many New Zealand homes built before 2008 were not required to have underfloor insulation. If your home is older or built on piles, there’s a good chance it’s losing warmth through the floor or has damp air rising from below.

Spring has arrived, and with it the opportunity to start planning those summer renovations. If you’re repainting or renovating your home, it provides a great opportunity to insulate your walls at the same time!

How insulation can help lower expensive power bills
Energy Efficiency

Winter power bills can put a lot of pressure on households across New Zealand. Many families find that no matter how often they run their heaters, their homes never feel as warm as they should.

Home heat loss and where it happens
Insulation

Home heat loss is one of the biggest reasons many houses across New Zealand feel cold and are expensive to run during winter. Without the right insulation, a large amount of the warmth you pay for can escape before it ever makes a difference.
