Many post and frame buildings have been insulated with Fiberglass insulation. This process was better than nothing however now many of these poorly insulated buildings are in need of a tune-up. Because of the fact that the metal sheathing has many penetration points through holes and mis-aligned laps in the siding, this leakage has been known to severely de-value the preformance of the existing insulation that protects the building from heat gain in the summer and heat loss in the winter.
So what can a owner of one of these structure do to correct the leaky building syndrome with out tearing the building apart? Well the answer is RetroFoam. One of the products that RetroGreen Energy offers is RetroFoam. RetroFoam is a non-expanding, shaving cream like foam that is injected into the wall cavities of such post and frame structures.

Chris didn't start RetroGreen Energy because he wanted to be in the insulation business. He started it because he wanted to fix homes the right way.
After earning his BPI Building Analyst certification and Minnesota Building Contractor license, Chris spent years studying how homes perform as systems. He saw firsthand that most comfort and energy problems weren't caused by old windows or outdated furnaces — they were caused by air leakage and inadequate insulation that nobody was diagnosing properly.
In 2009, he launched RetroGreen Energy with a commitment to doing things differently. Every project would start with proper diagnostics. Every recommendation would be based on data, not sales targets. And every homeowner would get the honest truth about what their home actually needed.
