Lessons learnt for airtightness & IWI at Lower Royd radical retrofit - @billbutch latest blog:

, our IWI strategy at the project involved around 100mm thickness of Diathonite Evolution IWI, which was applied 25 mm at a time. Diathonite Evolution is usually applied at thicknesses of 30 – 60 mm. Our aim is deep retrofit to around the Passivhaus retrofit EnerPHit standard, which will be the standard necessary for a lot of the retrofit in the UK if we are to meet the challenges of climate change. This means wall U values of around 0.35 W/m2K and an insulation thickness of 100 – 125 mm. So, Lower Royd has been a testbed for Diathonite Evolution in the UK for deep retrofit, at this thickness. There has been quite a bit of interest in our work. AECB researchers have installed 17 moisture Omnisense sensors in the walls and Leeds Beckett University’s Centre for the Built Environment are also undertaking heat flux tests on the walls. This work has kindly been funded by Diasen...
