Project Profile: Insulating a Concrete & Steel Stud Structure 1

Energy Effi­ciency

Spray foam makes sense. Espe­cially when heat­ing a 10,000 sq. ft. struc­ture. Spray foam insu­la­tion (SPF) is the per­fect choice. SPF will save the busi­ness owner hun­dreds of dol­lars a year in energy costs.


The Steel Stud Challenge

As with many com­mer­cial struc­tures, Pawn Amer­ica is a con­crete and steel stud struc­ture. When Shin­gobee Builders  framed the Pawn Amer­ica struc­ture, they left an inch between the con­crete block exte­rior and the steel studs. This allows room for an inch of spray foam insu­la­tion between the two. Since 1 inch of Bayer Bay­seal Closed Cell spray foam cre­ates a mois­ture bar­rier, Pawn Amer­ica won’t have to worry about mois­ture wick­ing through the con­crete wall and con­den­sat­ing on the steel studs.


Qual­ity Installation

To pre­vent con­den­sa­tion, it is impor­tant to get spray foam behind the steel stud. Cer­ti­fied installer, Aaron Schu­mann is care­ful not to miss any­thing. “It takes more time,” said Schu­mann. “I need to make sure to get both behind the stud and under the ridge on the steel stud. Wood studs take just 1 or 2 passes; it takes 3 or 4 to make cer­tain I get behind a metal stud.”

An inch gap between the steel stud and the exterior concrete wall leaves room for spray foam insulation; creating a thermal and moisture barrier.
