RetroFoam of Michigan is an insulation contractor specializing in residential injection and spray foam insulation, servicing homeowners across Michigan's lower peninsula. Our mission is to WOW homeowners with an unheard of contractor experience to achieve maximum comfort and energy efficiency through the means of environmentally friendly foam insulation. We also give our customers a life-time warranty on our products and labor.

"The team had such a lack of regard and care for my home and personal belongings, that I am actually extremely concerned about the parts of the job that I cannot see behind the walls and in the attic. The team did not clean, move, cover anything as promised by the sales team and advertised on the website. Many of my kids toys, wagons, strollers, and some tools were ruined. Some of the toys were thrown out and I spent hours cleaning and scrubbing my garage. The application of the foam itself was also a disaster. The foam leaked through the recessed cans and into the bathroom fans, since they were not appropriately covered. There was full material on my carpet in the bedrooms. The fans had to be replaced. The company did ultimately repair the drywall in the garage, but cannot replace the hours of work I personally had to do in cleaning up their mess, and fixing the light cans, bathroom fans, cleaning the carpet."

"Lacks integrity, dishonest and untrustworthy Do yourself a favor and call another company. My experience with this company was very poor. Went through a difficult situation throughout a job. They turned their back, didn’t take ownership and deflected blame. I took this company to court and was compensated. I’ve heard from other dissatisfied customer’s this isn’t the first time nor the last … You reap what you sow. If you choose to do business with this company protect yourself, do not sign their hold harmless and do not trust their word. This company states it’s built on integrity, honesty and trust. Just because it’s a veteran owned company doesn’t mean they inherently have these traits. I’d argue if a veteran has to highlight that, they are the opposite of what they say."

Insulation questions, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

While more is seemingly always better when it comes to energy efficiency, your house does need some interaction with its environment. Adding too much insulation can affect your home's ability to breathe. Breathing simply means ventilating itself to reduce accumulated moisture within it. Too much insulation can physically block the venting ability or be enough to trap the moisture and damage the insulation or the house.

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.
