The house we are currently living in was insulated with a type of blow in foam insulation. It was pumped in as a foam and then dried out. When I remodeled our bathroom this summer I found out that when the insulation dried out it came away from the walls, studs and dropped down. We now have approximately 3/4 inch of gap between each of the studs and the foam and 1/2 inch gap between the walls (inside and outside) and the foam and probably 3 to 4 inches under each window and the foam.
How do I get more insulation in the walls?I will reside this summer and thought it would be a great time to do it. Some one did suggest getting something in the walls to breakup the foam and then start over with cellulose insulation. Any better ways?
