Basement Insulation

Where To Insulate & When To Use Vapor Barrier

Heat will always travel warmer to cooler areas until there is no longer a temperature difference. Insulation retains heat by resistance to flow. Tiny air pockets within the insulating material slow down the transfer of heat and cold.

Basement insulation can be fiberglass below grade, mineral wool for ceiling of furnace room , cellulose above grade/interior walls and ceiling, closed cell spray foam for the rim joist and more. Basement insulation can be done with closed-cell spray foam directly applied to foundation walls creating a moisture (water), pressure (air), and thermal barrier for the walls and box sill.

Basement insulation (below grade) is commonly completed using fiberglass or cellulose, provided a vapor barrier is installed beforehand. Important to consider water management around the property before finishing a basement to ensure basement waterproofing is satisfactory before closing off access. Don’t insulate a wet basement.
Closed Cell Spray Foam Basement Walls

Closed Cell Spray Foam Basement Walls

Closed cell spray foam provides an effective solution for insulating basement walls by creating a seamless barrier against air, moisture, and thermal transfer.

Applied directly to the foundation, it ensures a tight seal that prevents energy loss, manages moisture and reduces air infiltration.

Closed cell spray foam insulation is ideal for problem areas like rim joists and headers, offering exceptional durability and efficiency for both finished and unfinished basements.

Was Your Finished Basement Done Correctly?

What Does It Smell Like?
A simple but effective first step. If you pick up a bad or musty smell that is a sure-fire sign there is moisture in your basement.

What Can You See?
Odds are, if you pick a musty or bad scent, you can locate other signs visually. Take a look around; is there mildew or mold growing anywhere? Most common places mold can be found will be in corners and on the ground where the floor meets the wall. Are nails popping out of the drywall, especially rusty nails?

What Can You Feel?
This might be uncomfortable, but if you are walking around in the basement in your socks, do your feet feel damp?

Romuno and his team came on time and were very cordial and friendly. They discovered 
an issue with some electrical work while working on the insulation, which I was surprised and happy about, and were able to rectify the situation easily and at a great value, considering the timing of the project, etc. Romuno made it clear he want to ensure my satisfaction throughout the process.  When finished, the job site was cleaned very well.
I highly recommend this company and all its team members and hope to do more projects in the future with them!

These guys did a great job! Great price, quality service, and they offer several payment
options and plans. I thought we bought a lemon of a house and the insulation and sealing job they did fixed all of our issues and were so thrilled! Highly recommend these guys. Plus they are local so it’s great supporting a chicago based company.

Highly recommend Green Attic. Scheduled to have  my attic re-insulated and Romulo
and his crew did a fabulous job. The attic was in pretty bad shape prior to the work getting done and green attic made it look so good. The crew worked efficiently and got the job done in 2 days. I also asked Romulo to install a couple other things on my roof outside of the scheduled project and he very kindly and willingly did so without hesitation. Very pleased with how everything turned out. Thank you so much for a job well done! Before and after pics below.
