  • Patent number: 10870984
    Abstract: A spray foam formulation used to form a spray foam insulation layer in a wall structure is described. The formulation may include the reaction product of a polyisocyanate compound and a polyol compound; a fire retardant chosen from at least one of a non-halogenated fire retardant; and a reactive halogen-containing fire retardant, and a carbohydrate. The spray foam insulation layer has an insulative R value of 3.0 to 7.2 per inch, and a density of between about 0.3 to about 4.5 pcf. Further, spray foam insulation made from the spray foam formulation may have fire retardant characteristics that are equivalent to or better than a similar spray insulation foam insulation using non-reactive halogenated fire retardants such as tris(1-chloro-2-propyl)phosphate (TCPP).

  • Publication number: 20200173165
    Abstract: A polyisocyanurate foam insulation product is produced from an isocyanate component and a polyol-containing component including a blowing agent. The polyol-containing component comprises one or more polyols, a fire retardant, and a hydroxyl-containing low-molecular-weight additive effective to increase the R-value per inch of the insulation product as measured at 40° F., as compared with an otherwise-identical formulation lacking the hydroxyl-containing low-molecular-weight additive. The polyisocyanurate foam insulation product may have an R-value per inch of at least 6.0 when measured at 40° F. and may have an R-value per inch of at least 5.5 when measured at 25° F. Suitable hydroxyl-containing low-molecular-weight additives may include triethanolamine, trimethylolpropane, N-methyldiethanolamine, 1,4 butanediol, or another suitable multi-functional alcohol or combination of multi-functional alcohols.
