Hi everyone,
I am currently having a single storey flat roof extension on the rear of my bungalow.
I am at the roof insulation stage and would appreciate some advice.
Its a cold roof I have 175mm joists, I am planning on leaving a 50mm void to the deck can I use jablite sheets and what thickness do I need.also I am unsure how to fit these boards around the herrinbone struts. Just a thought could I use rockwool?
Any advice appreciated.
I am not a builder, I have had the block ad beam floor, cavity walls and roof installed by profesionals, and signed of by bco. Now its down to me to finish on a budget.
