The exterior access to this crawl space was in good shape. However, it was uninsulated and it was not air tight. This means it allowed heat to radiate in and warm humid air to flow into the crawl space. We installed an interior friction fit door behind the access door. The interior door provides an R-10 of insulation and air seals behind the crawl space access. This seals a big hole that adversely impacts the crawl space otherwise.

This attic had existing loose fiberglass insulation with an R-value of 3.2 per inch. This material allows air to easily pass through it and escape into the unconditioned attic and out of the home. For this homeowner, we installed an R-38 of blown-in cellulose insulation. Cellulose is more dense than the loose fiberglass, is 85% recycle material, and is fire retardant due to being manufactured with borate, a substance that deters pests.
The homeowners wanted to focus on insulation and energy efficiency in this area of the attic. The boards and old insulation were removed from the attic, and our team set to work air sealing and insulating the space.
Together, the air sealing and cellulose will reduce conditioned air loss and heat transfer between the living space and the attic. This will leave the homeowners with more comfortable rooms, fewer drafts, and lower energy bills.
To help this Portsmouth, VA homeowner improve the insulation in their attic and resolve uneven temperatures in their home we installed blown-in cellulose insulation in the attic.
