Garage insulation question
Posted: 04 Oct 2019, 12:41
I've been asked to convert the rear half of a garage into an office come man cave for a friend of mine; due to the arrival of their first child in March he's being relegated to the garage!; its not attached to the house in any way but it is one of a pair of semi detached garages, the other owned by a neighbour. Its approx 10 years old and he's in a permitted development area but am I right in thinking he will be exempt from building regs due to the limited size of the garage?; he won't be losing the up and over door but there will be a stud wall approx halfway in, the office will use the rear half glazed door. Size of office is approx 2.7 x 2.4 so a smallish area. Heating will be via an oil filled rad although I have suggested a wall mouted convector but wall space will be minimal once he's moved desks, filing cabinets etc
I'll need to insulate the walls but its not really my field of expertise, are 50mm battens with Kingspan insulation in between enough or should I use an insulated board as well? Ceiling with 150mm insulation and I thought a floating floor on 100mm kingspan with a membrane under the kingspan. Mechanical ventilation instead of a window?
Our local council is being somewhat less than helpful and want to see drawings befor they comment or give any advice as to insulation, damp measures etc
Any views or advice would be welcome
