This was an older home in Pontiac with nothing in the walls. We removed the siding and drilled holes in the exterior sheathing to fill the walls with regal cellulose. achieving an r-13 for an 2x4 cavity.
This home was an addition in warren where the home owner wanted 1" of spray foam in the walls for air sealing filled the rest of the space in the cavity with cellulose through the mesh and blow method. this method will give you the best of both air sealing and cellulose for added insulation and sound control with out the cost of 3" of spray foam.
This was a job in Troy the home owner was finishing the basement. standard fiberglass batt was used on this job keeping cost down. fiberglass batts were used in the walls and bonds of this home before drywall went up.
this was a job at Wayne State in Detroit that we used 2# closed cell spray foam in the ceiling of this structure to help insulate it against condensation problems from the concrete.
this was a job in Royal Oak where we did the walls and attic with cellulose and sprayed the bonds with 2" closed cell spray foam. the homeowner noticed a huge difference upon returning from work just in how much quieter the home was from outside noise not to mention the two rooms that started the insulation request were still cool from the sun shinning on the brick all day.at the end of the day another very happy customer.
insulation for your crawl space is a very important part of the overall picture of efficiency. the best method is closed cell spray foam. at 2" you will have an r-14 plus air sealed creating a conditioned crawl space. you will have less air leakage and warmer floors plus it helps guard against pest's getting into your home.
these are the bonds of the home where the top part sits on the foundation. this area alone can account for 10-12% of the air leakage of your home. if you currently have fiberglass in them you are loosing energy. the best method to fix this is having closed cell spray foam sprayed into the bonds to better air seal and insulate. this picture is of one with fiberglass installed parts are missing leaving the uninsulated bond exposed and the penetrations open as well.
these are bonds insulated with closed cell spray foam at 2" you are getting an r-14 and you are about 95% efficient plus you are air sealed. will help reduce pest intrusions.
The Importance of air sealing. This picture shows the amount of air leakage from one recessed light by the dark spot around the light now times this by the amount of lights, ceiling fixtures and top plates you have in your attic and this can add up to be a lot of air movement. This can be solved by air sealing the penetrations and top plates in the attic before the insulation is added.
