Hi guys, well, Ive not spent much time on the garage lately due to a lot of holidays and a lot of work, however I have taken 11 days off work to get a load of work done before the fall. The first two days I was ill so did nothing but today I have come on in leaps and bounds, I have decided to remove the 50x50mm box section shelf supports and do away with them. I have placed double foil lined 1" insulation into the concrete garage wall cavity structure, then built a wooden 3x2" tanalised frame bolted to the concrete structure, inside the garage and infilled it with 2" jabalite insulation. thus most of the garage has 3" of wall insulation lined with OSB board. All of the walls will be completed like this, hopefully this week. The ceiling will be the same OSB board with 6" of loft insulation.
