Polyurethane Insulation

Polyurethane is an organic polymer formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives.

Polyurethanes are flexible foams used in mattresses, chemical-resistant coatings, adhesives and sealants, insulation for buildings and technical applications like heat exchangers, cooling pipes and much more.

• Calculate Conductive Heat Transfer
• Calculate Overall Heat Transfer Coefficient - U-value

Thermal conductivity vs. temperature are indicated in the charts below:

• T(^oC) = 5/9[T(^oF) - 32]
• 1 W/(m K) = 6.935 (Btu in)/(h ft² °F)
