Achieving air tightness

After the first air tightness test at the 1950's refurb (see previous post), we were very honoured to have a visit from Bill Butcher, Director of the Green Building Store. Bill has many years of sustainable building experience and was one of the team working on the world's first Passive House with cavity wall construction (in Denby Dale).

Bill spoke about his experiences of low energy building projects to a gathering of sustainable builders (AECB members). The discussions focused on achieving air tightness, and the 1950's refurb provided many examples of areas that present challenges!

To name a few: round the windows and doors, round pipes and cables, up through the edge of the floor, through the walls where plaster is missing / cracked, round the joists, at the eaves, and almost anywhere in the loft conversion!

Over the next few weeks, we'll be working hard to banish all draughts - with progress updates from time to time at
