Project Profile: Spray Foam Insulates Hard to Reach Areas


Owa­tonna Power Plant, Owa­tonna, MN

Eas­ily Conforms

One of the ben­e­fits of spray foam insu­la­tion is its abil­ity to con­form to unique archi­tec­tural char­ac­ters of a build­ing project. The ren­o­va­tion at the his­toric Owa­tonna Power Plant is the per­fect exam­ple. This exten­sive retro­fit project required insu­la­tion in and around hard to reach areas such as exist­ing stair­wells, walls, pipes and wires. Any sort of tra­di­tional batt or loose-fill insu­la­tion would have been extremely dif­fi­cult to install and would leave gaps and voids in the insu­la­tion. Since the ren­o­va­tion project was to con­vert the his­toric power plant into city offices, any insu­la­tion voids would make the office space drafty and uncom­fort­able in win­ter months.

 

Energy Effi­ciency in Hard to Insu­late Areas

In the case of the Owa­tonna Power Plant, spray foam insu­la­tion not only con­formed to insu­lated hard to reach areas, it also pro­vided a high R-value. At a depth of 2 inches thick, spray foam insu­la­tion pro­vided the new office space with an R-value of 14.

 

Fire Bar­rier

Many build­ing projects use sheetrock as a 15 minute fire bar­rier. Installing sheetrock in the his­toric power plant’s hard to reach areas also proved an issue. In this case, the 15 minute fire bar­rier was achieved with 18 mil of fire bar­rier coat­ing. Two coats of the fire bar­rier was eas­ily installed over the spray foam.

18 mils of fire barrier coating sprayed over the spray foam gives the building a 15 minute fire barrier.
