Why Glazing Matters for Health and Comfort
17/11/2025
Guest: Ruth Henderson, Managing Director, Vacuum Glazing Network
Host: Andy Cameron-Smith, Communications Director, Healthy Homes Hub
Vacuum glazing may not sound exciting—but as Ruth Henderson explains, it could quietly transform the health, comfort, and carbon performance of UK homes. In this episode, Ruth shares her unexpected journey from special needs education to leading innovation in glazing, and why windows deserve a central role in retrofit and decarbonisation strategies.
Key insights:
Glazing is a health issue: Beyond energy efficiency, good glazing prevents condensation and mould, stabilises indoor temperatures, and reduces noise—improving comfort, sleep, and wellbeing.
Retrofit potential: With 80% of the buildings that will exist in 2050 already standing, improving existing windows is crucial. Vacuum glazing such as Passive Glass allows landlords to upgrade performance dramatically without replacing frames, cutting waste, cost, and disruption.
Affordability and longevity: With a 30-year lifespan and minimal installation impact, vacuum glazing provides landlords and housing providers a realistic route to meeting EPC C targets.
Health and comfort benefits: Schools, offices, and homes report quieter, more stable internal environments, less condensation, and lower energy bills.
