VORATHERM™ CN Series – Anticipating Market Trends & Meeting Stringent Fire Standards
The growing influence of sustainable building initiatives is driving the demand for construction materials that contribute to the energy efficiency of buildings, helping to reduce their carbon footprint. At the same time, both national regulations and insurance companies have become more stringent regarding fire performance of insulation materials.
Dow developed an innovative PIR technology, the VORATHERM™ CN Series. VORATHERM rigid foams, which are based on advanced formulation and material science know-how, are designed to address specific manufacturers’ requirements in terms of foam physical properties, processability and fire properties. The systems address the growing demand of PIR foam insulated panels by keeping high productivity, good processability and overall durability in panel end-use applications.
VORATHERM™ Systems are a versatile solution for the construction industry:
- Excellent fire properties
- Good thermal insulation
- Balanced processability
- Remarkable panel durability
