I have just stripped my 105sqm 1900s 3 storey house back to bare brick as it had damp problems. I was planning to replaster throughout (using sand and cement render for lower ground floor) A builder would be doing the work. I have since learned that i will have to insulate the whole house to ensure u values are 0.35 or less if this is to comply with building regs. I am on a very tight budget - does anyone have any idea how i could achieve compliance (eg exact materials) and idea of cost. Also on such an old building would not the insulation encourage more damp? I have trawled the internet for 3 days now trying to find a simple solution but am confused with everything.
Any ideas on a budget product that would do the job simply
Thank you for your help
