Polyurethane is a versatile cellular plastic with unsurpassed insulation properties. Depending on its formulation, polyurethane foam may be open celled or closed celled, rigid, semi-rigid or flexible. It can be cast, moulded, poured or sprayed in densities ranging from 10 kg/cubic metre to 300 kg/cubic metre. 

Foamed Insulation provide sprayed in place and poured in-situ closed-cell, rigid foam ranging from 30 kg/cubic metre. They are capable of providing both on-site and in-factory services.

Features of this rigid foam insulation include:

  • Heat transfer resistance (“R” value) is a common standard of insulation performance. Polyurethane foam is effective in resisting the heat transfer or heat loss.
  • Sprayed rigid foam forms a seamless insulating barrier, which prevents incursion of outside air that is a major source of heat loss.
  • Properly protected rigid foam is virtually immune from water penetration, which degrades effectiveness of insulation.
  • Sprayed rigid foam does not sag, buckle, pack down or mat, which are conditions that reduce insulation effectiveness.
  • When foam is applied to the upper side of a roof, covering with an elastomeric, bituminous or acrylic membrane is necessary to protect it from ultraviolet rays of the sun.
