Residential Wall Insulation:
Little Product... BIG Benefits!
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
- 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
- It does not emit VOCs or hydrocarbons and has a proven track record over the last 20
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
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.
Tanks and Vessels
Spray Polyurethane Foam (SPF) can be used in a variety of different applications, one of those
is tanks and vessels.
SPF can be a solution for cold vessel insulation for products such as
wine, chemicals, and soft drinks. It is excellent to store products that need controlled
temperatures. SPF systems are perfect for these type insulations because of the superior
durability and ease of application.
Spray Polyurethane Foam can also be used for hot/warm vessel insulation. If there is a need to
maintain temperature control and/or viscosity levels of chemicals or other liquids, SPF
fluid-applied systems and protective coatings offer superior performance.
Use polyurethane foam sealant to improve your homes “envelope” in its outer walls, ceiling,
windows and floors. This is a cost effective way to improve your home’s energy efficiency and
- Thermal and sound insulation
- Seals windows and doors
- Blocks insects and rodents
One component can foam is an economical and effective insulating and sealing expanding
polyurethane foam. Designed for sealing cracks, seams and smaller gaps, it will eliminate
drafts, block insects, deaden sound and repel moisture.
Can foam expands to 2-3 times the original size of the dispensed bead and cures by reacting
with the moisture (humidity) present in the air when it is dispensed. This polyurethane foam
takes approximately 45 minutes to an hour to cure in 50% relative humidity. While air sealing
is the primary use for these materials, they also insulate with R-values (aged) in the 3.5 to
5 inch range.
Two-component polyurethane foams (or froth foam units) come in separate containers, one for
each component, and tanks operate conveniently from an upright position. Two-Component Standard
Foams are ideal for Insulating and Sealing jobs that require a product designed for spray
application over large surface areas or for filling large voids and gaps. Two-Component Foam
is a chemically cured foam system. Each Foam pack includes both an “A” & “B” component. Dispensed
through the included dispensing tool, the foam “A” and its curing agent “B” are mixed at the
nozzle and cure much more quickly than One-Component Foams.
Fast chemical curing results in a higher expansion ratio for two-component polyurethane foams.
This makes them suitable for spray-on applications and for filing holes and cavities. They have
an R-value (aged) of approximately 6.0 per inch.
Spray polyurethane foam is used as an adhesive in the commercial roofing industry and the
manufactured housing industries.
SPF is used to adhere EPDM membranes or boardstock insulation to various roofing substrates.
The SPF is used to stick the boardstock to the roof deck and then again stick the membrane to
the boardstock. The SPF is spray-applied which reduces application time and labor. The foam
provides an added degree of insulation and forms a strong bond, earning it excellent wind
SPF is also used in manufactured housing. The foam adhesive is used to attach wall panels and
ceiling panels to structural stud framing. This has many advantages to the builder, speed of
building, added strength, and lower costs.
The performance of a spray applied polyurethane foam insulation (SPF) system for cold storage
facilities can be affected by all the component parts of the building structure, as well as
the atmospheric conditions inside and outside the structure. Proper structural design,
specifications review, contractor and material selection, coupled with the compatibility
and positioning of the various components of the building are a necessity to produce a
successful cold storage facility.
Consult with the designer/specifier and the successful contractor to receive written
confirmation of their agreement/opinion to all facets of the cold storage project, including,
but not be limited to, material selection, moisture vapor transmission, load design, expansion
joints, and refrigeration requirements, flashing details, and floor, wall, ceiling preparation,
and pull down schedule.
Types of cold storage facilities
- Refrigerated warehouses generally have a single function of storing previously processed
or frozen food at a constant temperature between -40oC (-40oF) and 10oC (50oF). They are
often one room buildings. Packaged goods are stored on pallets or food racks.
- Processing plants for meats, poultry, dairy or other food products are multi-functional
type structures which are quite complex. They typically consist of many rooms, each with
a certain function, operating temperature and humidity condition.
- Distribution centers are multi-room buildings for packaged dry goods, frozen foods,
fresh produce, baked goods and dairy products. In addition to the above, these centers
may contain specialty rooms such as banana rooms or ice cream holding rooms.
- Existing facilities may be converted to another use, i.e., a cooler may be converted to
a freezer, or a new room may be added within an existing structure.
