Stop the (energy) leaks in your home

Gaps around your windows and doors are air leaks through your home’s thermal envelope − these gaps allow for a lot of energy (heat) losses and increase your heating/cooling costs. A well-sealed thermal envelope, coupled with the right amount of insulation, can make a real difference in your energy bills. BRANZ research estimates that homeowners can lose almost 10% on heating energy through gaps in your home.

Improve the comfort of your home

Insulation helps keep your home warm in the winter and cool in the summer. When correctly installed, insulation can deliver comfort and savings, especially during the hottest and coldest times of the year. Sealing leaks and adding insulation can improve the overall comfort of your home and help to fix many of these common problems:

  • Reduced noise from outside
  • Less pollen, dust and insects (or pests) entering your home
  • Better humidity control

In fact, if you added up all the leaks, holes and gaps in a typical NZ home’s thermal envelope, it would probably be the same as having the back door open every day of the year!

Most homes in New Zealand don’t have enough insulation and older homes have significant air leaks.  Closing uncontrolled air leaks around your home and adding insulation are two of the most cost-effective ways to improve energy efficiency and comfort in your home. By tackling both projects, you can maximise your comfort and could save you up to 10% on your annual energy bills.
