Testing Existing
R-Value
Does your existing insulation meet current standards? More Importantly does if function as intended? Performance is measured in R-Value. R-Value is a scale of heat retention. Often Insulation is improperly installed, leaving gaps and cracks for air to travel through. Lastly, air quality is an important test.

R-value tells us how well insulation can resist heat flow
R= Resistance to heat escape.
• Attics is R-49/60
• Sidewalls R-21
• Cantilevered Floors R-38
• Transition Walls R-21
• Basement Walls R-13
• Crawlspace Walls R-21
Illinois current standards are moving closer to a 4.0 Air Exchange Rate and R-values consistent with optimal standards.

Cost difference vs r-value difference
What is the difference in cost of different insulation materials to achieve same R-Value?
✕ Fiberglass R-Value 2.9-4.2 per inch
✕ Mineral Wool R-Value 3.0-3.2 per inch\
✕ Urea formaldehyde foam insulation 5.0per inch
✕ Plastic Board R-Value 3.7-6.0 per inch
✕ Sprayed foam R-Value 3.0-7.0 per inch
✕ Vermiculite R-Value 2.1- 2.5 per inch

Illinois current standards for construction. Choosing the right materials.
From mineral wool to radiant barriers, spray foam insulation, fiberglass insulation, foam board insulation, blown in cellulose insulation or some other less common form such as sheep’s wool, denim or others, each is measured in terms of its R-Value. In Chicago, current standards are measured in R-Value ( the resistance to heat escape ) measured on a scale from 0-70 for all intended purposes of this example.

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!

Romulo and his teammate were so fast and clean at insulating and repairing our damaged
ceiling due to a roof leak. Again it was easy to engage green Attic as a return customer because I felt well treated with their work when they first insulated and managed.to transform our cold home. Great job!

Had our attic insulation beefed up with new blown in cellulose. Was a major improvement
immediatly after it was installed. Cut our heating needs by 3x to maintain temperature in the house.Team working on my house was friendly and professional. Team leads Romulo and Omar did a great job making sure everything was done right and everything was cleaned up after.

Romulo & Alvaro did a great job installing everything. Cindy, Frank and the Green Attic team
were extremely attentive. I love how easy they made the process, everything is online even the rebates.
BONUS: I originally reached out to them to check for mold free of charge.

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.
