At Cherwell, we’re committed to more than just supplying beautiful windows and doors—we’re playing an active role in shaping the future of sustainable, energy-efficient homes.
As interest in passivhaus glazing solutions and low-energy building continues to grow across the UK, the role of high-performance glazing has never been more important. Glazing is one of the most critical components in determining a building’s energy performance, comfort levels, and long-term sustainability. That’s why we guide homeowners, builders, and architects toward smart glazing solutions that deliver real results.
The Impact of Glazing on Energy Efficiency
Windows and doors are often the weakest link in a building’s thermal envelope. But with the right products and advice, they can become one of its greatest strengths.
Choosing the right passivhaus glazing solutions affects:
- Thermal insulation – Reduces heat loss in winter and heat gain in summer
- Airtightness – Minimises draughts and keeps temperatures consistent
- Solar control – Lets in light while avoiding overheating
- Comfort – Improves acoustics and eliminates cold spots
Whether you’re aiming for Passivhaus certification or simply want to improve your home’s performance, carefully specified glazing can have a transformative effect.
