Foil or "reflective foil laminate"s (RFL). Foil-faced polyurethane or foil-faced polyisocyanurate panels. Foil-faced polystyrene. This laminated, high density EPS is more flexible than rigid panels, works as a vapor barrier, and works as a thermal break. Uses include the underside of roof sheathing, ceilings, and on walls.

Residential energy audits are often initiated due homeowners being alerted by a gradual increase in their utility bills which often reflects the buildings attic as being poorly insulated. [ 17 ] An initial estimate of insulation needs in the United States can be determined by the US Department of Energy's ZIP code insulation calculator .
Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value (in K⋅m 2 /W) is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction.

In the case of SIPs, the creep potential of OSB faced SIPs with EPS or polyurethane foam cores has been studied and creep design recommendations exist. [3] [4] The long-term effects of using unconventional facing and core materials require material specific testing to quantify creep design values.
Novo Nordisk's and Eli Lilly's weight loss drugs can cost over $1,000 for a month's supply, while compounded versions typically cost a few hundred dollars. The FDA needs more support, Califf said.
