Cellulose Insulation
Basement Walls

Northern Climates like Chicago have insulation on basement / crawlspace walls  with cellulose above grade and fiberglass below grade. Things to factor in basement insulation are : 

Where To Insulate
When To Use Vapor Barrier In Your Basement

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 particles trapped in the insulating material resist the movement 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 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.

Existing Drywall On Basement
Walls Cellulose Dense Pack

Basement insulation ( below grade ) insulation is commonly done with fiberglass or cellulose if there is a vapor barrier installed before insulating. 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.

If you are looking for a company that couples outstanding work with outstanding customer service, then Green Attic Insulation is who you should definitely call. I truly wish I would have called them years ago as I have been putting off suspected issues that centered around extreme temperature fluctuations between winter and summer, along with poor ventilation, within my attic.

James is prompt, thorough, and personable -- responded to my website inquiry right away and made it easy to schedule an appointment (still haven't heard back from the competition -- that was three days ago). He provided a detailed and professional quote within minutes of being on site and saved me from spending $20k on an unnecessary new roof! I'm glad I contacted Green Attic.

Highly recommend! Green Attic is thorough, responsive, and professional. Although it has only been a month since we had the work done, the results are clear. Our house is more comfortable, while our gas consumption is down ~30% and electricity is down ~25%.
