This webinar explores BRANZ Levy-funded research into higher-than-expected percentages of framing, and therefore thermal bridging found in residential construction in New Zealand.
The webinar covers:
The research was undertaken by Beacon Pathway and found that average wall framing percentages are significantly higher than the 14%– 20% framing content generally assumed by regulators and industry. This means that construction R-values across the whole wall area are lower than expected, so it is unlikely that the expected performance across the whole wall is being achieved. There are also some distinct ‘weak points and blind spots’, and some areas of framing are highest in those areas already prone to condensation, such as bathrooms.
