phenolic foam การใช้

• Marketed under the name " Koolduct ", it is constructed with CFC-free phenolic foam and covered with a skin of Aluminum foil and fiberglass.
• An "'external wall insulation "'system ( or EWIS ) is a thermally insulated, protective, decorative exterior cladding procedure involving the use of expanded polystyrene, mineral wool, polyurethane foam or phenolic foam, topped off with a reinforced cement based, mineral or synthetic finish and plaster.
• Vacuum insulated panels have the highest R-value, approximately R-45 ( in U . S . units ) per inch; aerogel has the next highest R-value ( about R-10 to R-30 per inch ), followed by polyurethane ( PUR ) and phenolic foam insulations with R-7 per inch.
• Expanded polystyrene ( EPS ), has a k-value of around 0.033 W / mK . For comparison, phenolic foam insulation has a k-value of around 0.018 W / mK, while wood varies anywhere from 0.15 to 0.75 W / mK, and steel has a k-value of approximately 50.0 W / mK . These figures vary from product to product, so the UK & EU have established a 90 / 90 standard which means that 90 % of the product will conform to the stated k-value with a 90 % confidence level so long as the figure quoted is stated as the 90 / 90 lambda-value.
