One is GacoFill slow-rise spray foam. Holes are cut into the drywall, and this foam is injected into the holes in “lifts.” This process requires an empty wall (no fiberglass). When completed, you have a foamed wall that is much more efficient than a fiberglass wall.
So what do you do if the wall already has fiberglass in it? That’s tough. You are stuck with an inferior product. What can be done is cut a trench in the center of the wall (from about belt height to chest height) and remove that strip of drywall and then remove the fiberglass from the wall completely. Then the wall can be filled with GacoGreen open-cell foam, the drywall replaced, and the house becomes much more efficient.
Get foam, and stay warm! (or cool).

I’ve driven by it for years. From almost any vantage point in Dayton, Ohio you can see the tall black spire of the Kettering Tower dominating the downtown skyline. That is about to change for us, as we prepare to install a new commercial roofing system on this skyscraper.
WRi Applications LLC will go from looking up from below to looking down on the City from a height of 415′. There are many things to bring together to complete a project like this ie, safety, efficiency, and production. Are we up for the challenge? We are.
So for the next couple of weeks, be sure and beep as you go through Dayton. We will try to wave !!

For decades, the building industry in Ohio has been trained to ventilate crawl spaces and attics. In the old days, we didn’t insulate crawlspace floors, and we didn’t air-condition houses. Crawlspaces (especially the floorframing) were warmed by the houses themselves. Now that we insulate floors, crawlspaces are within a degree or twoof ground temperature. During most of the summer, this temperature is below the dew point of the outside air, even up north.
The whole point of venting a crawlspace is to remove moisture. If we could import hot, dry air from Tucson to vent moist crawlspaces in Birmingham or Cincinnati, venting crawlspaces would be a great idea. But for Cincinnati air to vent Cincinnati crawlspaces,the air needs to be dry enough to pick up moisture, and it needs energy (heat) to evaporate the moisture. This isn’t going to happen, and here’s why: Cincinnati air isn’t hot and dry. Neither is Toledo air, Tallahassee air, nor Toronto air.
A crawlspace is just a mini-basement and should be treated as such. In fact, it’s like a basement for trolls. So how do we fix it?
Don’t insulate the floor unless you have serious groundwater issues; insulate the perimeter with closed-cell spray foam and install a continuous ground cover (6-mil plastic) to keep out moisture. Make sure that you include the bandboard when you have the perimeter walls foamed. And permanantly close off the foundation vents by spraying over them or inserting a close-fitting piece of insulation boardstock.
This will avoid the dreaded mushroom scenario, and you won’t have to carry large bags of pink & black fiberglass out of your crawl space like many, many others have done. In fact, don’t put fiberglass insulation in your crawlspace at all. Ever.

Times have changed since Otto Bayer mixed those two chemicals together in 1939, making the first polyurethane foam.
- The 1940’s was a period of development for spray foam. The military quickly began to experiment with this amazing new material, even using it in a few places during WWII.
- 1957 Saw the first foam roof applied. It was on a rail car that had a leaky roof. Surprisingly the foam roof lasted for many years. This got the attention of chemists and developers and they needed a betetr way to apply it.
- During the 50’s and 60’s people were trying to figure out how to apply the material with a machine of some sort. To date, it had been sloppily mixed by hand in pails or buckets. Yeah, a better method was was needed…
- In 1963 Fred Gusmer developed a machine to spray foam. This was the first dedicated foam machine on the market. The industry would never be the same.
- Throughout the 60’s this was a period of experimenting with foams and coatings. What worked.. What didn’t?
- The 1970’s brought a new era of interest in spray foam. It also brought a fire or two with raised concerns about the flammability of polyurethane foam. Fire retardants were added to the formulas, and the energy Crisis under the Carter administration automatically drove people towards this new super insulation, even though most people didn’t know a lot about it.
- The 1980’s was a period of tremendous growth in the commercial/industrial roofing industry, and spray foam was a big part of that.
- 1990’s saw the first intrusion of government into spray foam. The Montreal Protocol (which contended that there was a hole in the ozone layer) sent the EPA into our industry to demand a blowing agent change. The R-11 foams (some of the best foam ever) had to be reformulated with new blowing agents in America. The industry developed 141b as an alternative and 1993 was a year of adaptation as we all switched over to the new formulations.
- The 2000’s saw the biggest growth in foam insulation yet. Energy costs were on the increase, and to satisfy homeowner demands, super-insulation was called for. Enter spray foam. This was also the period where the “information age” helped to educate people on spray foam insulation. They were also becoming dissatisfied with fiberglass insulation due to its poor thermal performance.
- In 2004 the EPA came calling again. This regulatory monster intent on “saving” people from imagined dangers told our industry that we could not use the 141b blowing agent anymore. Yes, this was the blowing agent that they approved in 1993. But now they had changed their minds. That forced the foam industry to find another blowing agent. It wasn’t easy. Only one company was able to develop a suitable blowing agent (245fa). This meant that the industry had gone from five suppliers of 141b to one supplier of 245fa. Government had created a monopoly. Price increases dominated the year 2005, until finally the price reached equilibrium and stabilized.
- Today: Fifteen years ago I would introduce people to spray foam when they called. They would either be interested or they wouldn’t. Today, the level of education has changed. People call this week and they usually have two questions. “How much?” and “When?”
In summary, spray foam is the most exciting insulation material available. Each day brings more success stories and wider acceptance. In ten years it will be the dominant insulation in our country.
