Unlike any other insulation product on the market today, polyurethane foam has the broadest application capabilities. Standard applications include, but are not limited to, replacing existing roofing systems; metal building walls/ceilings; tanks; freezers/coolers; controlled atmosphere storage facilities, roof monitors, glass windows, skylights, flotation, pour foam for cavities, etc., the list is almost endless! Polyurethane foam/coatings provide a seamless insulation that can be sprayed to any thickness to provide the necessary R-Value. It has the highest insulation  value, per/inch, of any type of insulation on the market today. In addition, foam has a minimum "closed-cell" content of 92% (which means it inhibits water absorption that reduces the effectiveness of any insulation). Foam will adhere to most common construction products including; wood, concrete, metal, glass, sheet-rock board, fiberglass, and many other surfaces making it an ideal product for use in new or existing construction.

1) Seamless - A sprayed polyurethane roof forms a seamless insulated roofing system. It has no joints or seams that often allow outside water and air to pass through the roofing system into the building structure. Whether a roof is 10,000 square feet, 100,000 square feet or larger in size, it will have NO SEAMS.

2) Eliminates Flashing Leaks - Because a sprayed polyurethane roof system conforms to the substrate and when installed is a seamless system, it is ideal for flashing parapet walls, roof penetrations and roof mounted equipment, including vents, pipes, stacks, HVAC equipment, skylights and cooling towers. Many roof leaks are caused by faulty flashings. Sprayed polyurethane solves this problems.

3) Elimination Of Ponding water - In re-roofing applications, ponding water may be eliminated by adding an increased thickness of polyurethane insulation in low areas. Building up the low areas and sloping the roof, so that it drains properly, wilt eliminate ponding water and the additional load factor that is caused by water accumulation.

4) Lightweight - The weight of polyurethane insulation is between 2-3 pounds per cubic foot. One inch of polyurethane insulation plus 30 mils of an elastomeric coating weighs approximately 60 pounds per 100 square feet, as compared to approximately 600 pounds per 100 square feet for a typical conventional four-ply built-up roofing system. This makes a sprayed  polyurethane roof system ideal for re roofing, as it is often possible to apply over an existing built-up roof without removing it.

5) Highest “R” Value - Sprayed polyurethane insulation has an "R" value of 7.14, enabling it to provide more thermal resistance with less material than any other insulation.

6) Chemically Stable –polyurethane roof systems are chemically inert. They are odorless, resist attack by either mildew or fungi and have no nutritive value.

7) Rigidity -While sprayed polyurethane insulation is very lightweight, it is strong and will not pack down or sag.

 8) Minimises Thermal Shock - Because a  polyurethane roof system is seamless, has a high "R" value and uses a reflective elastomeric coating, it greatly reduces the thermal shock a building is subjected to by fluctuating outdoor temperatures.

9) Versatility - Polyurethane Insulation can be used on both new and replacement roofs, whether flat,
pitched, saw-toothed, domed or having unusual slopes or configurations. It is also ideal for application to tanks, freezers, coolers, piping, ductwork and various aerospace projects.

10) Flexibility - It has the ability to withstand a structure's normal expansion and contraction without affecting the ability to keep the structure protected from the outside elements.

11) Watertight - Polyurethane insulation is made of billions of minute closed cells which resist the penetration of water and vapors. It must, however, be protected by an elastomeric coating suited for use in that particular environment.  Coatings are specifically engineered for this purpose.

12) Long – Lasting - The elastomeric coating system which protects the polyurethane insulation can be rejuvenated by the re-application of additional coating after the initial coating system has weathered after many years of service.

13) Ease of Application - A polyurethane roof system can be applied in a relatively short period of time with little or no disruption of building operations by our experienced and qualified roofing crews.

 14) Ease of Maintenance -Minor repairs  or modifications to a  roof system can be made by in-house maintenance personnel. All that is needed is a hand caulking gun and a tube of caulk.
