Short Answer #
Insulation slows the movement of heat in and out of your home, helping maintain a more stable indoor temperature and reducing the need for heating and cooling.
Overview #
New Zealand homes have historically been under-insulated, leading to heat loss in winter and overheating in summer. Insulation is one of the most important components of a high-performing home, but it must be part of a larger system.
Key Points #
- Insulation creates a barrier that reduces heat transfer through walls, ceilings, and floors.
- Higher insulation levels improve the home’s ability to retain heat.
- Common issues in standard homes include low insulation levels, gaps, poor installation, and thermal bridging.
- Insulation alone is not enough. Airtightness, high-performance windows, and proper ventilation all need to work together.
- Better insulation leads to warmer homes in winter, reduced heating demand, and improved comfort.
Common Questions #
