HI
Building a conservatory .. becuase of situation I have to dig 1m to
1.5m to put the foundation in for a cavity wall. Will bring the wall up to 600mm(above DP)Question: Do I/should I, cavity insulate all the way up, or just the
600mm above DP ?also ... should I use a cavity closer at the DP point ..if I only insulation above this point ?
What is the normal practice .... Many thanks for any help.
