What is the best exterior insulation to put over existing double brick?
We are in the process of doing a major rennovation + second story addtition to a double brick 1940's bunglow. The inside will be be well insulated to code with an HRV, etc., but we also are looking to add 1" of rigid insulation (our builder has suggested 1" EPS) to the full exterior and finally clad it with Hardie Boar...
