Tools editor Steve Maxwell runs his own website at www.stevemaxwell.ca. A recent post suggests a way to get spray foam insulation installed at a less-than-crazy price. If you have a customer that wants spray foam but balks at the cost, try this…
The essence of his idea is to cut foam board insulation to fit in between the studs of the wall, and then do a thinner spray foam finish over it to fill the cracks.

This is not a new concept and has and is being widely used. The key is to use the foam to air seal and then use traditional fiberglass or other as insulation. What kills insulation is the air flow through the material.
