Taking the old insulation down revealed the thing that matters here: a 16th century oak frame, five hundred years old and still carrying the roof. Everything after that was arranged around leaving it visible.
Flexible wood fibre went between the rafters and rigid boards under them, cut to sit behind the oak rather than across it. The loft room was insulated with chamfered hempcrete blocks, the suspended floor with mineral wool before the boards went back down. Lime plaster finishes every panel, sun tunnels bring daylight into the kitchen, and the frame reads exactly as it did before we started.
Working with Adam and the rest of the Eco-Renovations team has been brilliant. With his experience, skills and knowledge in period properties, it was clear he was passionate about this difficult build. Adam effectively became project manager for us and we could not be more grateful.

If your building is listed and the frame is part of what you love about it, insulation does not have to cover it up.
