Great Falls, Montana, population 56,690. Known as "Electric City" because of its proximity to several
hydro-electric dams. What better place to show how GREAT STUFF™ Insulating Foam Sealant can save
on heating and cooling bills than Electric City? Speaking of heating and cooling, Great Falls is the perfect proving ground for GREAT STUFF™ because the city experiences real extremes when it comes to weather.
In fact, on January 11, 1980, Great Falls registered the most rapid temperature change in US history:
-32 degrees F to 15 degrees F in just seven minutes. That's almost seven degrees a minute! The record
high is 106 degrees F and the record low is an incredibly low -43 degrees F.
