PURL GPW-4 Part B is a fully formulated polyol blend designed to react with PURL GPW-42 Part A to make a general-purpose water blown rigid polyurethane foam.

Polyurethane rigid foams have a closed-cell structure and high crosslinking density give them the characteristics of good heat stability, high compressive strength and excellent insulation properties. PU insulation has a very low thermal conductivity, starting from as low as 0.017 W/m.K, making it one of the most effective insulants available today for a wide range of applications. All types of insulation can also play a role in improving the energy efficiency of buildings and reducing CO2 emissions.

The environmental impact Polyurethane offers is as follows;

  • Excellent thermal efficiency – leading to optimum energy savings and reduced CO2 emissions
  • Relatively low environmental impact at the building level – the product saves more than 100 times the energy than is used in its manufacture.
  • Durability – leading to long term performance and reducing the need for replacement, therefore saving energy.
