Lessons learned from EWI - How Retrofit Design is crucial for delivery
Delivering high-quality retrofit is not just about installing the right measures. It’s about the design decisions that shape performance, comfort and long-term outcomes.
In this on-demand webinar, Domna’s retrofit specialists, Managing Director, Matt Ratcliff, Technical Director, Andres Gonzalez are joined by Soltherm’s Technical Director Mark Gibbs to explore why design is the defining factor in successful retrofit delivery. Drawing on real-world experience from External Wall Insulation (EWI) projects and whole-house retrofit programmes, the session looks at how early, rigorous design reduces risk, prevents unintended consequences and supports predictable outcomes at scale.
The session is grounded in delivery experience and focuses on what actually makes a difference in practice.
What the session covers:
- Why retrofit should be treated as a design challenge, not an installation exercise
- How whole-house thinking underpins effective retrofit outcomes
- The role of ventilation in fabric-first retrofit programmes
- Design lessons from live External Wall Insulation delivery
- How collaboration, when applied correctly, strengthens independent design
- What good, design-led retrofit looks like in practice
