From start to finish the personnel who helped us insulate and make our home more comfortable were polite, knowledgeable, factual, and demonstrated a professional knowledge and understanding of how to insulate and make our home comfortable. The energy audit was complete and well documented what steps needed to be taken in our home to decrease our energy consumption and make our home more livable and warm this winter. We were presented with actual pictures of the problems found and accurate costs for make corrections. The options were left up to us with no pressure and many alternatives.
The actual crew that arrived on time, carefully provided cover and drop cloths for all areas, prepared all areas and kept us informed as to how the work was progressing. They anticipated that it might be a day and a half, but were finished and all cleaned up within the first day. Insulation was added to our attic and double garage celling thus insulating the bedrooms above and the pipe sealing and work in the basement went as planned. Extra care was taken as ceiling fixtures in three rooms were retrofitted with new LED lighting and all work was completed in a professional manner. We are so pleased with the work completed by Sustainergy Cooperative and are more than happy to highly recommend them to all of our friends in the Cincinnati area.

The crew from Sustainergy Cooperative were great. They were honest about the needs for insulation in the home without trying to only make money. They adjusted the original contract when they saw that there was already insulation in one of the areas. Everyone I spoke with via online or on the phone or in person was professional and very friendly.

The materials used are high quality and have made a huge difference in the comfort of the home even after one night. The installers were friendly, efficient and knowledgeable. They worked all day with very few breaks and completed the job quickly.

You would never know that this job had been done because when they left they cleaned up any and all debris, leaving the house in top condition.

Their price was extremely reasonable as compared to the other estimates we received for the same amount of work/materials.

I would, and have already, highly recommended them to others. Their mission is admirable as well. Please give them a call to meet your insulation needs.

Sustainergy Cooperative patiently completed an unconventional project in working with me, a guy with an architectural background who lives way up in Hamilton, OH. I really appreciate their accommodating my budget/geographical constraints and, at the same time, atypical ventilation requests and modifications.

For instance, they installed 2 attic gable fans, added soffit vents and removed old insulation from the sloped attic rafters to improve the house ventilation. This is not the typical insulation job and yet they completed my difficult requests. Flequer was very thorough, thoughtful, open-minded and spent a lot of time coordinating with me. I really appreciate this. I also appreciate the very difficult, confining and dirty work that Chris, Samir and Lindsey had to deal with while at the house. They were very friendly and polite - professional in sum.

In terms of a critique, there was one point in which I am glad that I double-checked the work of one of the co-owners. As mentioned earlier, I had requested that increased ventilation be added; more specifically, under the roof-sloped rafters between the side crawl space and mini attic above. One of the team members had shoved rigid foam board insulation into the old insulation, essentially packing/bunching up the insulation rather than increasing air flow. This would have nullified the effectiveness of the soffit vents that I had him do earlier in the project. After discussing this concern with the team, they patiently came back and did the job per my difficult/unique request.

Given all of this, I would say that I have gotten a good deal on a difficult project and I want to give the co-op credit for not giving up when I had changed my admittedly difficult requests. So, in sum, I would definitely use their services again and recommend them to anyone out there who's reading this. Well done!

Blown Cellulose

80-85% recycled newspaper with fire and pest retardants added, does not grow mold, works great for sound proofing, pest repellant, not bad for your lungs, and cost effective.

Dense Packing

One of the most effective ways of dealing with existing uninsulated frame walls is to blow cellulose into the wall cavities. This is a popular and time-proven method of retrofitting insulation and is a mainstay of low-cost weatherization programs. It is popular for good reason—it works very well. Dense packing walls typically results in remarkable performance. It is the dense packing of unvented cathedral ceilings or unvented flat roofs that is the problem. The job can be done from either inside or outside of the house.

Foam (Open and Closed Cell)


Typically water based and very light density, this foam has the consistency of angel food cake. It weighs about .5 pounds per cubic foot. Air bubbles inside the foam burst open, hence the name "open cell." Some types of open and closed cell foam have a soy base, although this soy base is still typically accompanied by strong chemicals.



Typically oil-based, high density (1.25-2 pounds per cubic foot) hard foam. It is a fairly mature product that has been out for 30+ years. Made of two parts, it catalyzes when mixed and cures quickly. Air bubbles inside (cells) do not burst, hence the "closed cell" designation.

Radiant Barrier / Reflective Insulation

Tin foil on steroids. Originally called Multi-Layer Insulation by NASA who invented it for the Apollo missions, it is typically two sheets of foil with a different type of thin insulation between them, either bubble wrap or fiberglass. They reflect radiant energy. Sunlight is the best example of radiant energy. Campfires are another example. Our bodies also produce a lot of radiant energy which is why emergency road kits often include a foil blanket. Beware, though: lots of snake oil surrounds this product.
