Spray  Polyurethane  is  the  High-Tech  insulation  material  with  lowest  K  Value  per thickness  of  any  readily  available insulation material used in residential construction. The K Value  means  Thermal  Conductivity  Value  and the lower it is, the  superior is the insulation material. It  is applied  by spraying  the  material  which  becomes  rigid in less than a minute.  Sprayed-in-place  Polyurethane  is  a self-adhering, seamless, closed cell foam with excellent compressive  strength.  It  can  be  tapered  to  improve  water  drainage on  an existing roof, eliminating the detrimental effect of standing water.

The versatility and performance of a seamless sprayed-in-place Polyurethane  system makes it a practical and economical solution  for many applications.  It provides a seamless weather barrier  when utilized as a roofing  system and permits wall insulation.  As self-adhering, light weight  seamless insulation, it does cover a  variety of substrates.  The direct adhesion to the various  component  surfaces (including  concrete,  wood,  metal,  plastic,  concentrate  and others)  creates  a  monolithic  unit  that  gains substantial strength.  It forms up to fill cavities completely  bonding  the  various  elements  together  for  rigidity and stiffness.  The resulting envelope of insulation offers lower K-Value and air infiltration resistance.

Formed  by  reactive components in  the presence of other additives, Seamless Polyurethane foam  is a  rigid  closed  cell  insulation.  The  superior  insulation  and  air-seal characteristics provide the  owner  with a long-term  value based on permanent reduction of cost of energy. Worth over 25 years of application, this product has been successfully field-proven time and time  again.  As  a  purchaser, you  are  making  a  sound  decision  in  selecting  your  Spray Polyurethane Roof Insulation system.
