Photo Album: Blown-in Insulation Improves Comfort in Hainesport, NJ

This homeowner had numerous comfort complaints. After replacing the furnace and air conditioner with super high efficiency Amana equipment, we sealed and insulated the attic. All rooms are now the same temperature! The homeowner received a $4000 rebate and 0% interest loan from NJ's Home Performance Program.

Old insulation is displaced so attic air goes around it and affects ceiling temperature below.

When insulation looks like this, attic air is getting around it!

The bath fan is venting into attic and can lead to mold growth from moisture.

Blow in cellulose insulation being installed over top of old insulation. All building gaps under the old insulation were sealed with spray foam and the old insulation was laid flat before the cellulose was installed.

We have to get into some tight spaces to apply blown in cellulose insulation!

12-inches of insulation was added above the old insulation. It reduced the amount of heat transferred thru the ceiling by 67%. It also saved energy because it covered the ductwork in the attic so it didn't lose as much energy to the harsh attic.

This is the same view as Before - Photo 3. The cellulose insulation knits together when it is blown and forms a level barrier that prevents air penetration while reducing heat transfer from the conditioned rooms below.
