Icynene Products
ICYNENE LD-R-50
ICYNENE LD-R-50® spray foam insulation is a revolutionary, renewable-based formula made using castor oil. This has many environmental and health-related advantages. LD-R-50 is a one-step performance material which both insulates and air seals a building for the lifetime of the structure. Icynene LD-R-50 is guaranteed to perform as specified for the life of the building.
Renewable Material
A portion of the polyol in the LD-C-50 formula has been substituted with castor oil:
- Reduces the need for petroleum-based polyol
- Is a natural/safe ingredient can be used in personal care products such as lip balm
- Crops are non-irrigated, saving water supplies
- Can be grown on marginal lands, which are not competitive with food production lands.
Performance Benefits
- Stable thermal performance. More on air sealing and R-values
- R-value = 3.7 per inch
- Superior sound control. More on noise reduction
- <5% water absorption
- Vapor permeable, support bi-directional drying of assemblies
- Soft, flexible composition maintains an air seal even after seasonal expansion/contraction of building assembly
- Supports indoor air quality by blocking air infiltration and mass transfer of moisture that may cause mold. More on indoor air quality
