Cutting really thick EPS foam
I have a job coming up where there is going to be 8″ of foam under slab.
The foam will be glued at the joints.
Over the years I have cut foam a number of different ways with varying levels of success.
I have used Tajima knives, circular saw, sawzall, handsaw, sharpened putty knives, table saw.
All of them worked ok, none great.
For this job I want clean, straight, glue-able cuts and I have never worked with foam this thick so I am a bit nervous about too much trial and error since it will all be custom ordered. My main problem in the past when I have had foam that is thicker than my cutting implement is having the cuts stay square.
Any thoughts or advice from folks who have dealt with really thick foam before? What has worked for you?
