Applications we have insulated with Spray Foam
Below are listed a number of projects or applications where spray foam was used. Any place that varying conditions must be separated from one another, a type of foam insulation can be used. Whether temperature, moisture or sound are needing to be controlled, foam can be used as a solution.
New Construction
These pictures are from a new construction job. Notice that foam was sprayed directly on the underside of the roof sheeting along with the gable end walls. This process was used to create a conditioned attic space. This process is counter intuative at first glance, although after having inspecting this attic during both temperature extremes for a few year I am completely sold on this practice. During my inspections the temperature variation in this attic never exceeded 10 degrees warmer in summer months or 10 degrees colder in winter months than below the un-insulated drywall lid. Plus the relative humidity followed that of the home so I could take a nap at 3pm on the hotest day of the year in the attic without any discomfort. Code approval to spray 6 inches thick, (R-24) is acceptable because of the higher performance of foam. The 2x4 framed walls are also sprayed with foam along with the caulking of top plate, bottom plate, headers and buck studs.
This home owner could not believe how clean the home stayed. No loose fill insulation sifting through can lights or ceiling fixtures. Add mechanical ventilation and the air in your home will be cleaner than out of doors. We have had customers with pet allergies reduce or eliminate medication due to this combination.
Existing Homes
These photos are of a log home built in the early 2000's. The home owner had been plagued with high energy bills because of heat lose and a big ice build up on the roof for many years. The temperature throughout the home varied significantly, and for the last few years during the winter months and they noticed water running down the interior walls staining the logs. A roofing contractor was called in to investigate why the steet roof was leaking. After opening up the ridge vent and a few valleys he noticed a significant amount of moisture in all of these areas. It was determined that the roof was not leaking but the ventilation was not working properly causing condensation. Keep in mind that this house was insulated to the standards of the Michigan Uniform Energy Code, (R-38 fiberglass batts with styrofoam ventilation shoots from the soffit up to the ridge). After a significant effort to get the ventilation to work properly the problems continued. Thermal Imaging diagnostics confirmed that a significant heat lose scenario existed and the only remedy was to remove the rough and groove ceiling and replace the fiberglass batts and styrofoam vents with spray foam insulation sprayed directly against ther roof deck, (approved by the MUEC). The pictures listed below show this process and the resulting conditions were very successful. 6 inches of soft foam, (R-24) was sprayed directly on the underside of the roof decking after the surface mold was treated. This process was very expensive. Can you afford this misapplication of insulation in your home?
