We’ve all experienced days when it’s ridiculously cold outside and it’s horrendously difficult to heat your home up. Likewise, I’m sure you recall stupidly humid days in summer when it’s incredibly tough to cool the home down! This happens because the inside of your home is like a little atmospheric bubble, with air inside always trying to equalise itself with the outside temperature.
Your homes insulation helps to provide a barrier which makes it difficult for air to escape from your home. It helps keep the inside temperature warmer or cooler for longer and helps to reduce the effort it takes to control the air temperature. In New Zealand homes however, homes are generally only insulated to the minimum standards, which usually means a difficult and costly process for heating and cooling your home.
When you think about insulation, you usually think about the stuff they put in the roof and sometimes under the floor. What you may not realise however, is that for most New Zealand homes there is little to no insulation in the walls and this creates a gap in your home’s thermal envelope. So what’s a thermal envelope anyway?
Simply put, the thermal envelope is a barrier created from all the different products and materials used in the construction of your house. This barrier helps protect the inside environment from the outside climate. Everything from your roof and concrete slab to your windows and insulation help to make up this barrier. Unfortunately, even the best built houses often leave gaps or weak points that allow air to escape in an out of the home, with your walls being responsible for up to 30% of your homes heating and energy loss.
If you think about it there’s a lot of ways the air can escape through your walls. If your windows are thin, there are gaps in and around your doors, or if your walls aren’t well insulated air can easily escape. The break in your homes thermal envelope means that any effort you put into heating or cooling your house is quickly lost, however, there are things you can do to plug the gaps!
Replacing your old thin window glass with new double-glazed windows helps fix a big part of the problem. Changing old wooden doors with better joinery can also help fix the gaps in these areas. The main issue for most houses however is the lack of wall insulation so the best way to fix your thermal envelope is ensuring your walls are well insulated!
