Roof Insulation
This week we have started started installing the Celotex insulation over the exposed Oak. This involves laying 12.5 mm foil backed plaster board directly on top of the Oak then a layer of 80 mm Celotex, roofing batten is then laid in the same direction as the Oak rafters and fixed in place with 150 mm decking bolts then 30 mm Celotex is laid in between the battens.
The roofers will then lay counter battens, breathable membrane and then the tiles!
