Wall Insulation

See How It's Done

RetroFoam injection insulation is a game-changer in retrofit insulation for existing homes.

Many homeowners in Minnesota experience comfort issues, high-energy bills, ice dams or even
allergies or mold from high moisture levels in the place we call home. The fact of the matter is
the most homes have hidden air leaks and old outdated insulation the can allow uncontrolled
movement of air and moisture causing many of the problems home or business owners seek to
solve. RetroGreen Energy focuses on a whole house as a systems approach including the walls
attics and foundations. We realize that insulation means more than blowing some more stuff in
an attic just to make you feel a false sense of accomplishment. Many homeowners we have
worked with didn’t even know they had more than 1 attic or the importance of advanced air
sealing hidden under old attic insulation, or that their walls have the original insulation only
filling 25% of the walls from 1974. The hidden spaces that are between walls, behind the
sheetrock or below a floor are the mystery spaces most owners avoid or forget to think about.
For RetroGreen Energy this is our proclaimed playground for major progress against your
Whether its old wall insulation causing rapid room cooldowns in the winter or a
sunbaked south and west facing wall heating up a bedroom in the summer. RetroGreen Energy
understands the history of how homes were built, how insulation products were used and the
impact our crazy weather patterns have on homes. We have the tools, the staff and knowledge
to implement new technology into all existing structures.
RetroGreen Energy specializes in the use of various types of spray foam and injection foam
insulation and blown natural fiber cellulose for many different applications that equate to

the past have run their course, the science and physics of heat and air flow in homes has now

occupant air quality and prevent damage to the structural components of a home.
