Polyurethane Insulation

Thermal conductivity of polyurethane insulation - temperatures and k-values

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.

Relationship between temperature and thermal conductivity:

Polyurethane insulation - thermal conductivity versus temperature

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