In-Situ Sprayed Polyurethane Foam(SPF)

profile-image

Sprayed Polyurethane Foam (SPF) or PuF is the best integrated waterproofing and thermal insulation system with lowest thermal conductivity (0.023Watt/MK@25Deg.C which is much lesser compared to other insulation materials available in the local or international market. According to a study by department of energy, heating and cooling costs amount to 50-70% of the energy used in the average American home. With the costs of heating and cooling going up, this is a concern of most home and building owners. Most of us know to turn off the lights to conserve energy but don't think to look to insulate our homes/buildings to more efficiently heat and cool them. Builders and architects are now turning to spray polyurethane foam (SPF) to curb these problems.

A SPF Roof is a "Green" Roof. Since SPF is an integrated system, it enables us to eliminate the use of different products to achieve the desired waterproofing and insulation. It is considered as the best thermal insulation ever known. Since there are no joints from where the heat could escape from the final surface, makes SPF even better than Polystyrene or Polyurethane ready boards because the final surface becomes one big board without any joints heat or moisture can seep through and also because of the possibility if controlling the thickness of SPF layer as per requirement.

SPF is formed by reaction of liquid polyol resins with isocyanate components sprayed by a special proportioning machine with a gun that mixes the two components in the nozzle itself. Because of its very light weight, it is most suitable for large sheds like multiplexes, hangars, warehouses, schools as well as private villas of any shape SPF Roofing Systems provide many benefits to building owners. The two most prominent benefits are waterproofing/leak prevention and insulation value. Many additional benefits also exist such as superior compressive strength, lightweight, self-flashing, durable and long lasting.There is no better home insulating material that can seal your home from air and moisture intrusion, save on costly utility bills, strengthen your home, and protect your health from dangerous mold than SPF insulation.

Some of the Advantages are :

  • Complete Waterproofing & moisture resistance, with high efficiency in thermal
  • Stops air and moisture infiltration
  • Reduces noise considerably
  • Makes your home more comfortable & healthy
  • Saves 30-40% on energy costs
  • Adds strength to the roofing structure
  • Its permanent and will not sag
  • Keeps dust and pollen out
  • Reduces maintenance and wear of HVAC equipment
  • Excellent adhesion to all surfaces in any possible shape
  • Very light weight of about 3-3.5 kg/Sqm for 50mm thickness, ideal for Corrugated AC/Metal roofs
