Global Dwelling Case Studies: Sealing Gaps and Blocking Drafts in Shokan, NY

Sunday, April 8th, 2018 by John Kotsides


Gary liked to come home every day after work and eat dinner and relax in front of the TV in his favorite chair. Unfortunately, every time the wind would blow in the winter, he would feel a cold breeze rush over him. Over time, his frustration grew and he was speaking about it to a friend that had used Global Dwellings services in the past and recommended that he call our company to see if we could help. We came out the following week and met with the customer to see what was going on. He showed our Home Energy Specialist, Gamal, where he would sit when he would feel the cold drafts. The first thing that Gamal noticed was that it was directly adjacent to the pocket door between the dining and living room. Gamal conducted a blower door test and, low-and-behold, a tremendous amount of air was pouring out from the door pocket. Gary was perplexed. Gamal told him that he was heading to the attic to see if he could connect some dots and would report back with what he would find.


Gamal found his way over to the area right above the pocket door and pulled the insulation back to reveal a large gap directly above the door. Since pocket doors need a thicker wall cavity to slide in, builders would routinely side nail studs to the top and bottom wall plates to thicken the wall by 1 1/2". This would leave a substantial gap in the attic and basement and connected the attic to the house. Cold dense air would drop down through the opening unobstructed and right over Gary's chair. The solutions was pretty simple once the problem was exposed. We sealed the top cavity with rigid foam and spray foam and the draft was eliminated.
