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.

Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value 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. [3]
A study conducted by CMHC (Canada Mortgage & Housing Corporation) on four homes in Paris, ON found that the performance of the bubble foil was similar to an uninsulated floor. It also performed a cost-benefit analysis, and the cost-benefit ratio was $12 to $13 per cubic metre RSI. [18]
In order to accomplish small gas cell formation in man-made thermal insulation, glass and polymer materials can be used to trap air in a foam-like structure. This principle is used industrially in building and piping insulation such as , cellulose, rock wool, polystyrene foam (styrofoam), urethane foam, vermiculite, perlite, and cork. Trapping ...
Extruded polystyrene or foil-faced foam board insulation. Exterior grade plywood, 0.70 US perm (40 SI perm). Most sheet type monolithic roofing membranes. Glass and metal sheets (such as in doors and windows).
[52] [53] The Solar Heat Gain Co-efficient (SHGC) [54] (a measure of solar heat transmittance) of standard single glazing can be around 78–85%. Solar gain can be reduced by adequate shading from the sun, light coloured roofing, spectrally selective (heat-reflective) paints and coatings and, various types of insulation for the rest of the ...
The generalised chemical structure of polyisocyanurate showing the isocyanurate group. The polyols are abbreviated as R-groups.. Polyisocyanurate (/ ˌ p ɒ l ɪ ˌ aɪ s oʊ s aɪ ˈ æ nj ʊər eɪ t /), also referred to as PIR, polyol, or ISO, is a thermoset plastic [1] typically produced as a foam and used as rigid thermal insulation.
