Eaves

With the loft insulation and external wall insulation almost in place, attention has again focussed on eliminating thermal bridges and maintaining continuity of insulation.

Eaves details were discussed between Baily Garner, Jenners and CEN. The issue was how to insulate this area in a way that was practical for installation, allowed ventilation of the loft to continue and minimised heat losses. The conclusion was that using phenolic board in the void would be so difficult to install, it ran the risk of leaving gaps for heat losses. Instead, plywood boarding was applied to the rafters to prevent the mineral wool being applied to the void from blocking ventilation to the loft space.
