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.
