This residential structure presented numerous problems with the original construction from 50 years ago. The attic was vented with two large gable vents and the joist spaces between the second floor ceilings and the old attic floor were jammed with fiberglass insulation batts and loose fill creating a dangerous environment from breathing fiberglass insulation particulates.
The solution to this situation was to safely remove all of the existing fiberglass and to treat the entire attic as a conditioned space.
Ecotec Insulation Inc. located in Skokie Illinois were contracted to remove the fiberglass and install 2” of closed cell foam insulation between the roof rafters and gable wall studs. The foam insulation was then sealed with SUPERTHERM ® providing a Class A flame spread rating, sound proofing and additional insulation.
The application of SUPERTHERM ® was most effective in eliminating the noise pollution from the approach pattern of O’Hare Field which is located next to the area of Park Ridge, Illinois.
SUPERTHERM ® applied to Attic.
The owners now enjoy a clean quiet conditioned attic space which is resistant to mold and is so effective as an insulated space that even on recent days with temperatures of over 100 degrees with a black asphalt shingled roof, the attic is now just as cool as all the other conditioned spaces in the home with only 2” of insulation.
This same system was also used to provide new sky lites above the indoor pool area. Because of the effectiveness of the two inches of foam and SUPERTHERM ®, we were able to reduce cost by using 2x4 construction to achieve adequate insulation performance. Without the use of SUPERTHERM ® this would have required 2x12s and 12” of dangerous fiberglass to achieve a lesser performance rating.
