Vienna VA Home Remodel with Insulation

This Vienna VA home was being remodeled and had its interior frame stripped down to allow for installation of more modern insulation products. Our team started working in the attic before addressing the inside of the walls in the rooms below. Old insulation was removed and the attic was air sealed with Zyp Foam in order to control unwanted air flow in and out of the space. A new attic floor decking was constructed by our team along with damning/walls to hold in the Tru Soft Cellulose Insulation that would later be blown in. A zippered Attic Tent door cover was installed to properly seal up the attic door and control air loss from the rooms below. The final result for the attic was a thick layer of insulation and a more energy efficient top floor of the home. The floor/decking would allow for storage space and the ability to walk around the attic.

Attic Insulation Project in Winchester, VA

A home in Winchester, VA was experiencing unbearably hot top floors during the summer months. The master bedroom was the worst - sometimes, the homeowners had to sleep in the downstairs guest bedroom to escape the heat! It came as no surprise to us that the attic had insufficient and almost non-existent insulation. It also had a vent that was directly allowing outside air in! It's no wonder that the rooms under this attic would be having these issues. To fix this problem, we first air sealed leakage points with spray foam. We then blew in a thick layer of cellulose insulation through the entire attic. This attic is now a conditioned space and won't contribute to comfort/efficiency problems any more!
