PUR (Polyurethane)

The polyurethane (PUR) is a polymer obtained by condensation of polyols combined with a mixture of polyisocyanates.

Their components are: rigid polyurethane, which is made by reacting a liquid polyol component with a liquid polymer isocyanate (MDI).

Noted for its closed cell structure, which make it a high quality insulation and low thermal conductivity, thereby allowing significant savings in energy consumption.

It has highly appreciated adhesive properties, which serve as bonding between layers of the panel to provide strength and durability tailored to the construction requirements.


Key Features:

  • PUR thermal resistance reaches 90 º C
  • Classification Bs2d0 according to European standard 13501.
  • High quality insulation composed of closed cells
  • Excellent material properties.
  • Operates at very low temperatures
  • Very low thermal conductivity, because of its density
  • Strong resistance to atmospheric agents.
  • 97% (roughly) the volume of the foam is trapped gas.
  • Lightweight and easy to handle, allowing to save assembly costs.
  • Mechanical strength avoids the risk of insulating foam lamination.
