Mix and match EWI and IWI?
I am looking to retrofit insulation to a 1930s semi detached house. The front of the house is of a particular type (part brick and otherwise for planning reasons cannot be altered with EWI). However the gable end and the rear of the house are suitable for EWI. Is it possible to apply IWI to the front walls and EWI to the gable and rear? Are there any issues arising.
Thanks for all replies.
