What is Continuous Insulation?

Unlike typical insulation installed between framing members, continuous insulation (ci) provides uninterrupted thermal insulation for unparalleled performance. Foam plastic products can also serve as the water resistive barrier and air barrier for a structure, providing a 3-in-1 building envelope solution.

Regardless of the name – from the more common “foam board” or “foam panel” to the code-defined “foam plastic insulating sheathing (FPIS)” – the science behind this approach to ci is worth spending some time on!
