Job Stories From Loudoun County, VA
Creating Storage in Attic over Garage

Many home owners in Northern Virginia finish their basements for additional living space.  One of the unintended outcomes of this trend is that there is a shortage of storage space for items like Tax Returns, Christmas Decorations, Seasonal flower arrangement, luggage and the like.  You know, the things you need every now and then, but not that often.

One strategy to create a storage space for these items is to convert the attic space over the garage into usable storage. 

This project will be broken into phases:

1)      Install pull down Attic Stairs to improve access to the storage space.

2)      Install Radiant Barrier to reduce the temperature in the attic during the hot summers of Virginia.

3)      Address the vertical wall that separates the attic space from the conditioned space inside the house.

4)      Install flooring and shelving to create the storage space.

More to come as the project unfolds.

Attic Storage Deck-Paeonian Springs, VA

A Paeonian Springs, Va homeowner was looking to upgrade their attic insulation, yet not lose the ability to store items in the attic with 16" deep insulation.  Comfenergy put together a solution that involved upgrading the attic insulation to R60 TruSoft cellulose insulation.  However, we cleverly installed an insulated storage deck for the homeowner using 4" thick foam boards with plywood over it for stability and strength. Plywood was installed on the sides (dams) to prevent the TruSoft cellulose from falling onto the storage deck!!!

Spray Foam in Attics - Thermal Bridging Considerations

When using Spray Foam in an attic to "Condition" the attic, we are often asked about thermal bridging from the roof rafters being exposed.

The photos below show how to base handle this in an environment where no sheething will be attached to the bottom of the roof rafters.  The film of spray foam is extended or "Wrapped" around the roof rafters in order to reduce the amount of thermal bridging through the rafter cross sections.

If you are considering the use of Spray Foam to insulate your attic, Please call Comfenergy so that one of our consultants can come and educate you on the best course of action for your home.  We are Experts in High Pressure Spray Foam Applications in residential construction.
