Drafty Top Floor-Stephenson, VA

Challenge

This Stephenson, VA home suffered from a drafty top floor in the winter. The culprit??? KNEE-WALLS!!! Knee-walls are often attached to a vented soffit, which allows outside air up into the knee-wall and then into the home. Most knee-walls (including this one) are insulated to code with fiberglass batts. This provides no air sealing capabilities at all.

Solution

The solution proposed by Comfenergy was to encapsulate the knee-walls with closed cell spray foam. This not only air seals the knee-wall, it also provides an excellent thermal barrier for the top floor. No more drafty top floor here!!

This home had a drafty top floor.....until they called Comfenergy!!

The beautiful Comfenergy truck poised to solve another comfort problem!

This picture shows the knee-wall where it meets the vented soffit. It has already been "blocked" with SilverGlo foam boards by the Comfenergy crew in preparation for spray foam.

The final product! Air sealed and well insulated. This homeowner will be warm and cozy tonight!
