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.
16 CFR Part 1209 (Consumer Products Safety Commission, or CPSC) – covers settled density, corrosiveness, critical radiant flux, and smoldering combustion. ASTM Standard C-739 – loose-fill cellulose insulation – covers all factors of the CPSC regulation and five additional characteristics, R-value, starch content, moisture absorption, odor ...
Insulative paints, or insulating paints, are a specially designed type of paint in which can be used to coat a surface (e.g a wall) to reduce heat transfer as well as increase the thermal insulating property (R-value in order to aid cooling and heating efforts for example [1].
Styrofoam can be used under roads and other structures to prevent soil disturbances due to freezing and thawing. [8] [9] DuPont also produces styrofoam blocks and other shapes for use by florists and in craft products. [10] DuPont insulation styrofoam has a distinctive blue color; styrofoam for craft applications is available in white and green ...

In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.
Thermal conductivity varies between 0.029 and 0.039 W/(m·K) depending on bearing strength/density and the average value is ~0.035 W/(m·K). Water vapor diffusion resistance (μ) of XPS is around 80–250. Commonly extruded polystyrene foam materials include: Styrofoam, also known as Blue Board, produced by DuPont
