Using Icynene Spray Foam insulation in existing construction.

Using Icynene Spray Foam insulation in existing construction.

It has a 60:1 expansion ratio.

I just saw a trade video by Icynene Insulation using spray insulation application in new construction, but, even a better application of pour in spray insulation that expands at a 60:1 ratio in existing wall cavities of say a older victorian home which might not be insulated at all and have just plaster walls. That is a tremendous opportunity for work.
