7 ways to reduce unintended consequences from solid wall insulation

The environmental and financial benefits of insulating the UK’s older building stock are significant. However, if this is implemented badly, a number of unintended consequences could be introduced that could jeopardise the integrity of the building elements and the health and wellbeing of the occupants.

A new report from BRE IHS press considers surveyors, designers and installers’ advice on assessing the potential risks and reducing the likelihood of long-term problems.

The report highlights seven ways in which most unintended consequences can be avoided.

Most consequences can be avoided by:

  1. Take an integrated approach to an installation by employing well informed surveyors, designers and installers
  2. Carry out more thorough surveying of candidate buildings to understand their existing properties, characteristics and any obstacles that will require specific detailing
  3. Select insulation options that complement the properties of the specific building
  4. Undertake a thorough assessment of exposure risk and hence the robustness of any proposed solution
  5. Draw up detailed designs of the system, particularly at junctions and interruptions, to design out thermal bridging that may undermine the thermal performance being sought
  6. Assess existing ventilation provision and ensuring suitable ventilation in line with the requirements of the applicable building regulations
  7. Check quality on site to ensure workmanship is of a sufficiently high standard and the intended detailing is implemented so as not to introduce weaknesses or undermine the performance of the insulation.
