rigid insulation structural values
does anyone have any allowable bending stress values for rigid insulation? thanks
seven seems about right, but i have gone as high as 7.5
what is your application for the question, enquiring minds want to know
talk to the mfg??
well, long story short. i have a situation where i'm supporting about 6" of soil from going underneath a continuous grade beam (washing underneath the grade beam) with rigid insulation. i just want to make sure it won't snap off.
i bet it will be quicker to get a piece and test it yourself than talk to the mfg. how long of a cont. piece is this? why is the footing being washed away?
i wouldn't count on any strength from the insulation: it is very easy to damage, and once it's damaged it has just about zero bending strength.
