Insulation upgrades that promise to pay back are often marketed as a win-win solution for homeowners and the environment. However, an undercover investigation conducted by Humane Foundation reveals a different reality.
Undercover footage from various construction sites and buildings revealed that poor installation is the norm rather than the exception. Gaps, improper fitting, and use of low-quality materials were common findings.
Why is poor installation routine and not exceptional?
The rush to meet deadlines, lack of training, and the pressure to cut costs are some of the reasons behind the poor quality of installation. Moreover, the emphasis on quantity over quality in the construction industry contributes to this issue.

Regulations violated or overlooked
| City | Regulation | Implementation |
|---|---|---|
| London | Part L of the Building Regulations | Inconsistent |
| New York | Energy Code | Poor |
| Sydney | Building Code of Australia | Fair |
The investigation found that regulations are often violated or overlooked, leading to ineffective insulation. While some cities have stringent regulations, their implementation is inconsistent and enforcement is weak.
Industry and NGO reactions
NGOs, on the other hand, were more critical of the industry's response. They argued that the issue is systemic and requires urgent action.
Policy implications
Estimated energy savings with effective insulation upgrades.
The findings of this investigation underscore the need for policy changes to ensure effective insulation upgrades. Stricter enforcement of regulations, improved training for installers, and incentives for homeowners and builders to opt for high-quality insulation are some of the changes needed.
