Knee Wall
This knee wall was created by an elevation in the ceiling. There is air coming up in between the wall straight through it constantly. The insulation will just act as a filter but not stop the air from going through it.
Air Sealed Hot Pipe and Top Plate
The hot pipe had a damn put around it and sealed to prevent a fire hazard by have insulation pushed agaisnt it. The top plate was sealed with spray foam to stop all air from coming up through the gaps around it.
Sealed Drop Sofft
The hole where the drop soffit is has a lot of insulation fall into it if not sealed. Dr. Energy Saver seals and insulates the hole with foam board and spray foam.
Spray Foamed Rim Joist
The rim joist was sprayed to seal all possible penetrations in so that no air, pests, insects, dirt, etc. can get through it. This 2 part spray foam also gives the rim joist insulation.
Spray Foamed Knee Wall
The knee wall was sprayed with 2 part foam so that the air penetrations were completely sealed. It gave a more insulated knee wall as well.
