Sprayed Polyurethane Foam (SPF)

Among prominent insulation materials in residential and industrial applications, polyurethane (PUR) and polyisocyanurate (PIR) are considered as best cold insulations. PUR and PIR are extensively used in oil, gas and petrochemical applications, residential and construction, pharmacy and food industries, piping and processing. PUR and PIR foams are available in different shapes, including: pre-formed blocks and boards, pre-formed pipe sections, injection foams and sprayed foams.


Sprayed polyurethane foam (SPF) is made of two major polyurethane constituent components, isocyanine and polyule. Sprayed polyurethane foam is mostly applicable for insulating walls, roofs and attics in residential, industrial and commercial buildings. Because the constituent components are preheated before installation and as a results, chemical vapors are exposed and due to the in-door applications, using protective equipment including masks or respiratory masks by experienced and trained insulator personnel is essential. Please make contact with provider, before use.

The constituent components of foam, which are stored in two different barrels, are heated up to the liquid phase and then, are sprayed over the wall or the surface to be insulated. During the spraying, the components react to each quickly and form polyurethane insulating foam. Due to constant spraying, all holes and cavities and cracks across the surface, consequently builds up a perfect insulating layer. The density of the foam and the pressure of the spray are adjustable. The less the density, the more open cell content in the foam. Once spraying operation is over, the surface of the foam become uniform, using a saw and the over-sprayed sections and disposal foams, are trimmed.
