Residential
Applications:
Spray Polyurethane Foam (SPF) insulation
is rigid, lightweight, flexible, wind resistant, and
effective in extreme temperatures and weather conditions.
SPF insulation has the highest R-value per square
inch of any commercially available insulation material.
Total Comfort
Control, Not Just R-Value
The building envelope is a system of construction
components which protect against the uncontrolled
movement of: heat, air, and moisture.The true performance
of your building envelope can not be measured with
the R-value of the insulation alone, but must also
consider air movement, moisture control, health, safety,
durability, comfort, and energy efficiency.
This is true whether your building is commercial,
residential, or multifamily: SPF addresses all these
needs in both new construction and improvements to
existing structures.
Six Mechanisms of Heat
Loss Through a Wall or Ceiling That Are Bad for Your
Home and Your Health
- Conduction
- Radiation
- Convection Currents
- Infiltration (Wind Pressure)
- Intrusion (Wind Wash)
- Moisture Accumulation (Humidity, Dew, and Frost)
Did You Know?
- Air infiltration can increase energy costs in
buildings 10 to 40%.
- SPF reduces air infiltration allowing insulation
to be more effective and reducing the demands on
HVAC equipment.
- SPF reduces moisture infiltration by reducing
air leakage.
- SPF adds structural strength to walls and ceilings.
- SPF reduces sound transfer into buildings. Most
sound from outside the building is carried into
the building through cracks and air leaks. SPF by
stopping the air infiltration also helps keep sound
out.
- SPF minimizes dew point problems and condensation.
- SPF resists heat transfers through air infiltration
regardless of flow direction.
- SPF provides reliable R-values under the most
extreme conditions, dependable and durable protection
against heat loss or gain.
- SPF minimizes thermal bridging, which can cause
higher energy usage and cost.
- SPF out-performs conventional insulation materials
because they trap still dry air and if that air
moves or becomes wet, the thermal resistance can
drop by 50%.
- According to ASHRAE, a 3% void area in a wall
cavity represents a 15% reduction in wall R-value.
Commercial Wall Insulation
Spray foam insulation could be the best insulation
system yet invented.
Look at the following advantages:
- On the inside of the wall panel of a building
it has an extremely high R value, it has been shown
to dramatically increase the racking strength in
steel and timber frame buildings, in some instances
has been specified to prevent wind uplift in commercial
roofing systems.
- On the outside of the building it can be used
as a combined vapor and air barrier system and is
recognized as such when applied to the American
Air Barrier Association standards. It can also be
used below grade for the insulation of basements
and foundation.
- It does not emit VOCs or hydrocarbons and has
a proven track record over the last 20 years.
Commercial Roofing
Spray polyurethane foam (SPF) roofing consists
of an application of specifically designed foam covered
with an elastomeric coating (typically acrylic, silicone
or polyurethane) or aggregate covering to protect
the foam from ultraviolet rays. Specialized equipment
mixes two liquid components at the spray gun that
applies the SPF to a prepared substrate. The mixed
liquid expands many times its original volume in a
matter of seconds, forming a rigid foam plastic that
chemically bonds to the surface to which it is sprayed.
Spraying the foam in ½” to 1-1/2”
lifts allows the applicator to reach the desired thickness
to fill in low areas, build up slope, and provide
insulation.
SPF has a closed cell structure that makes it water
resistant. It must, however, be protected by elastomeric
coatings or other coverings (such as aggregate) to
prevent ultra-violet-induced surface degradation.
Such coverings can also be used for other purposes,
including, inhibiting moisture vapor transmission,
enhancing the aesthetics of the system, increasing
the impact and abrasion resistance of the system,
achieving non-flammability and meeting code requirements.
SPF roofing systems have good adhesion to a variety
of substrates including metal, wood, concrete and
built up roofing (BUR). Since SPF adds little weight
to existing roof coverings and can build slope to
fill in low areas, these systems are used frequently
as a recover roofing system. Caution should be used
when specifying any recover roofing system. The existing
roof covering and roof deck assembly should be thoroughly
evaluated by a structural engineer to verify that
it can be a safe substrate for SPF roofing systems.
Hail and wind driven missiles (such as tree limbs,
broken roof tile, metal flashing, etc.) can damage
the SPF roofing system. However, this type of damage
typically does not cause leaks and can be repaired
later without compromising the long-term performance
of the system.
SPF roofing systems also excel when the following
conditions exist:
- Additional insulation is required
- There are severe temperatures
- The roof substrate has numerous penetrations
- The roof deck is an unusual configuration
- The roof is in an area where high winds are likely
to occur
- Lightweight materials are required
- Slope must be added to provide positive drainage
Because of the energy saving characteristics and
low maintenance costs of SPF roof systems, these roofs
are suited to companies or organizations that own
their own buildings and must pay their own energy
and maintenance costs. |
