Enhabit have prepared a tidy layout for the MVHR (mechanical ventilation heat recovery) system, with a PAUL NOVUS 300 unit providing the grunt.
The eaves detail requires special consideration to provide an air-tight line around the existing roof structure. Now we have exposed the top of the (uninsulated) cavity wall the challenge is clearer. The simplest solution seems to be boxing out with OSB and taping across the rafter and joist penetrations. The taping is proving to be surprisingly therapeutic.
Russel heard today that he passed the (very hard) exam. Phew.
Making roof ribs, which will provide support for the roof battens and tiles above the 350mm of roof insulation. The photo shows a special OSB rib for the gable ends where a ladder structure is being formed to extend over the gable wall and external wall insulation (EWI) system, with the prototype cardboard model.
As usual the planning process is proving to not be straight forward. Varying opinions on whether we actually need permission or not, then when we submit it they won't accept part of it and 'forget' to register the other part. We could go on...
