Bought a home that was built in 1974. It has wood studded walls with drywall, and brick veneer exterior, no insulation.
Coworker has a similar house and he paid to have foam pumped in two years ago, by a nationwide franchise company that advertises year round and has a scene in their commercials of insulating a brick veneered wall. Coworker was telling us how two drywall sections in his home were bowed due to the installers pumping in too much foam and he replaced those sections a year ago.
I thought I had read that brick walls need to have quarter of an inch spacing on the inside to allow condensation to drain, otherwise it may cause the mortar to begin cracking from freeze and thaw cycles over time. I have looked over the website of the nationwide franchise company and they don't provide those sort of details to answer my question. Can someone clarify for me?
