Superior Home Performance Case Studies: Tackling a Devil's Triangle in Bristol, CT

Tuesday, January 8th, 2019 by Korrin Leslie


Attic Systems by Superior Home Performance was called out to a home in Bristol, CT to see how they could make it more comfortable. The finished room above the attached garage had ice cold floors. The room was incredibly drafty and hard to keep warm. Superior's Building Science Specialist did an evaluation and found ways to take care of the homeowner's problem. The small space under the roof, directly above the room, had old, dirty insulation that was no longer doing it's job and hadn't been for a long time. This space is known as the "devil's triangle" and is not as easy to get to as a regular attic. Superior had to access that area and somehow provide full insulation to prevent heat from escaping the room consequently making it warmer. 


Attic Systems by Superior Home Performance sent their crew out for production to make this Bristol, CT home more comfortable. Superior's crew carefully removed the vinyl siding on the top of the gable end of the garage and cut and removed a piece of the sheathing to gain access in the “Devil’s Triangle”. Once inside they pulled out the old dirty, insufficient insulation. They then air sealed the interior plates of the gable ends and dense packed the slopes of the roof with exclusive TruSoft Cellulose Insulation. For the open area in the "Devil's Triangle", the crew blew-in TruSoft Cellulose for full coverage protection. Now the warm air this homeowner pays to heat will not escape through a leaky, poorly insulated attic. The crew also dense packed the garage ceiling with TruSofft Cellulose to prevent the floor in the room above to be freezing. This room has no more drafts and the homeowner doesn't have to worry about cold floors. The best part is this work is lifetime guaranteed and they won't have to worry about re-insulating in this part of their home ever again!
