Abstract: An insulated spa cover (10) contains a thermal insulating core (30), a top cover (150) with an average permeance of at least 57.2 nanograms/Pascal*seconds*square meters, and a hydrostatic head test value of at least 5,000 Pascals, a vapor barrier (130) and optionally a bottom sheet (140) apart from the vapor barrier. Venting pathways are defined around the thermally insulating core to facilitate escape of water vapor.

Abstract: An article contains a polymeric foam board having a primary surface and an intumescent coating on a primary surface of the polymeric foam board, the intumescent coating containing a polymeric binder, expandable graphite particles, a phosphorous material and a boron-containing compound and wherein the article is free of an object that is in contact with the intumescent coating and that sandwiches the intumescent coating between it and the polymeric foam board and wherein the intumescent coating has a tensile elongation of at least 50 percent and less than 100 percent at 23 degrees Celsius as measured according to ISO 37, has a storage modulus of less than 1×106 Pascals at 250 degrees Celsius, is halogen-free, free of sodium silicate, free of polyurea elastomer, and free of formals of pentaerythritol and dipentaerythritol.
