Making additions or alterations to an older home can provide an opportunity to improve its thermal performance. However, installing insulation to maximise the benefits is not always as straightforward as it might seem.
Designers should be designing roofs with enough space between the roof underlay and top plate for the thicker ceiling insulation now commonly used. Here are some options to avoid getting caught short.
When it comes to insulation, designers should think optimum rather than minimum and make key decisions early in the design process.
With electricity costs on the increase and air pollution a serious issue, thermal insulation has an essential role in keeping a building warm, dry and comfortable for its occupants while helping to preserve the environment.
Tricky access can be a problem when retrofitting insulation into an older home. However, as the push continues to insulate homes, we look at some of the options and things to consider.
Although steel framing in domestic construction has only a small market share, there are signs it may be on the increase. Since steel is a good conductor, builders need to be aware of potential pitfalls, such as thermal bridges and condensation.
BRANZ modelling identified six areas for designers to focus on to reduce the carbon footprint of a new build. In the first of this series, we look at the practical considerations for designers using rule of thumb 1 Increase construction R-values.
Older houses often don’t perform as well as new ones. Fortunately, there are plenty of ways to upgrade performance as well as modernise for form and function.
