| Why SPF? |
|
SEAMLESS
SPF is a seamless system. There are no seams or
joints to allow water and air to enter the building
through the roofing system. Regardless of
building size or shape there will be no seams.
|
WATER & AIR TIGHT
The closed cell structure of polyurethane foam
resists the penetration of water and air. It is a US
Coastguard approved material for flotation.
|
|
LIGHTWEIGHT
SPF roofing systems weigh approximately 60
pounds per 100 square feet compared to 600
pounds per 100 square feet for conventional BUR
systems. This is ideal to apply over existing BUR
eliminating the need for expensive tear-off.
|
SELF-FLASHING
Due to the ability of spray-in-place polyurethane
foam to conform to the surface it is applied to, it is
ideal for flashing parapet walls, roof penetrations,
and roof mounted equipment; such as HVAC
equipment, vent stacks, pipes, skylights, etc. The
self-flashing ability of the foam eliminates many roof leaks caused by faulty flashing.
|
|
ELIMINATES PONDING WATER
A unique advantage of spray-in-place
polyurethane foam roofing systems is the
ability to slope existing roof to allow ponding
water to be redirected to drains by adding an
increased thickness in low areas. This
means that each roof can be individually
designed to meet the customers needs.
|
INSULATES
Polyurethane foam has the highest “R” value of
any roofing product on the market. With an “R”
value of 7.14 it enables usLonghorn Urethane to
provide more thermal resistance with less material
than any other insulation.
|
|
FLEXIBLE
Polyurethane foam has the ability to withstand the
normal expansion and contraction of a structure
without affecting the ability to protect the
structure from outside elements.
|
VERSITLE
SPF can be used on new roofs as well as
reroofing projects. It can be used on surfaces
whether they are flat, pitched, domed, metal,
wood, concrete, etc. It is an ideal system for
insulation to tanks, coolers, piping, ductwork,
freezers, reefer trailers and perimeter wall
insulation for new construction homes or metal
buildings.
|
|
MAINTENANCE
A Maintenance Agreement is available to our
customers from Longhorn Urethane. In addition,
after a brief instructional meeting in-house
maintenance personnel can make minor repairs at
minimal cost using a hand caulking gun and
urethane sealant.
|
STRENGTH
While very lightweight, polyurethane foam is
strong. It will not pack down or sag.
|
|
LOWERS SURFACE TEMPERATURE
The white elastomeric coating used to protect the
polyurethane foam from UV rays adds the
benefit of lowering the surface temperature
of the roof from 200 degrees on a typical black
rubber roof on a 90 degree day to 120 degrees
for the SPF roof. The white coating is very
reflective and helps lower energy costs to the building owner.
|
LONG LIFE
SPF roofing systems are renewable. While other
systems need to be removed and replaced after
their usual life expectancy, SPF need only be
repaired and recoated with the elastomeric
coating system for many years of service.
|
|
EASE OF APPLICATION
A SPF roofing system can be installed in a
relatively short period of time with little or no
disruption of building operations.
