Increase Comfort and Energy Efficiency in Your Home and Basement with Spray Foam in the Rim Joist

Most homes in Michigan have insufficient or no insulation in their rim joist causing cold outside air to easily enter the home around the foundation area. Open cell spray foam expands 100 times to fill all the cracks and crevices in the rim joist. With a total air seal that other insulation materials can’t hold a stick to, spray foam in the rim joist is one of the most cost-efficient ways for homeowners to take control of the comfort and energy efficiency in their home and basement.


Updating a Rim Joist with Spray Foam Insulation is a Major Home Improvement for the Investment

Reduced Energy Bills

Preventing air leaks around your home’s foundation area in the rim joist increases your home’s energy efficiency and savings on monthly energy bills.

A Better Basement

The air seal created by spray foam insulation is key in creating a basement that doesn’t experience huge temperature swings and remains comfortable.

Added Comfort

With less cold air coming in from the outside, floors are more comfortable and drafts around the foundation are greatly reduced.

Improving Your Home’s Performance Doesn’t Have to Be Difficult

The process of insulating a rim joist is quick and simple for homeowners who want to get started with comfort and energy-efficient updates or for the homeowner ready to retrofit the entire house with foam insulation.


Insulating Your Rim Joist with RetroFoam of Michigan

For over 15 years RetroFoam of Michigan has been insulating existing homes across Michigan’s lower peninsula. Our consultative project managers, highly skilled crews, and helpful office staff have a mission to guide you through the whole process with ease, and we also offer a lifetime warranty on our product and workmanship.

If there is currently old fiberglass insulation in the rim joist, a crew will remove the old insulation and dispose of it so you don’t have to mess with it. They will then ensure any furniture or storage bins are cleared away from the basement walls. If necessary, the crew will then place plastic over the windows and any shelves and storage to make sure they don’t get overspray on them.

If we are also insulating your crawl space, the rim joist is included in that scope of work as well.
