This attic has a low R-Value (resistance to heat) and is not blocking the heat from escaping from the living area of the home. The insulation is not thick enough to stop cold air from entering the living area during the cooler months. This insulation is the original with some more insulation added on top at a later time.
Air duct in bad shape, not well insulated, causing the hot attic air to change the cool air temperature from the air conditioner.
Light Visible From Inside Home
There are numerous openings in the attic that are allowing conditioned air to exit the living area. The air escaping is a major contributor to the stack effect of the home. Warm air in the attic is pulling conditioned air through the openings as it exits the vents. The home has 70 can lights that are not sealed.
A new deck was installed to provide the homeowner with extra storage space in the attic. 4 inch SilverGlo foam board was installed under the deck to insure proper insulation.
The old insulation was removed, attic cleaned and sealed, and new cellulose insulation was blown-in.
Some of the duct was replaced, and the whole attic was air sealed.
