can this be used between the floor joists and plywood sub-floor for a cottage to provide some insulation and avoid cold bridges at the joists?
Hi, Mikemaninsul! Thanks for your question about DuPont™ Styrofoam™ Brand Cladmate™ Extruded Polystyrene (XPS) Foam Insulation. We apologize for the delay in responding to your question, there were some system issues that prevented us from receiving it until now. We would not recommend that you use Styrofoam™ Brand Extruded Polystyrene (XPS) Foam Insulation this manner as the point loads are too high. Instead, we'd recommend that a layer of plywood be placed directly on the joists followed by foam, and then a second layer of plywood. In addition, we'd recommend that you use a Type 4 foam, such as DuPont™ Styrofoam™ Brand SM Extruded Polystyrene (XPS) Foam Insulation, instead of the DuPont™ Styrofoam™ Brand Cladmate™ XPS.

Can I use this to put over 3" pvc pipe underground for added insulation. To cover sub pump pipe.
Sure you can use to protect from frost or freezing. I have personally used to block frost and freezing for a water line @ my cottage. I also used it to protect footing from frost 1 inch equals 1' of soil

How thick is the board? I see 2x8 but not thickness.
They like mixing units, metric and imperial. They used 12.70 mm instead of 1/2 inch. Imperial for feet.

I want to install new vinyl siding on my house, and use this product underneath. Do you recommend housewrap UNDER the insulation, or OVER the insulation? Do I tuck tape the joints? Thanks
