Rigid urethane foam is an insulating material formed by two chemical components.
The liquid components meet and mix at a spray gun. The material expands in a matter of seconds and within minutes of it's application becomes rigid.
The superior insulating ability of urethane is due to the presence of fluorcarbon vapor trapped in millions of tiny cells.
The self-flashing nature of the combination of sprayed urethane and liquid weatherproof coatings give an economical solution to the problem of sealing around penetrations in roofs for air handling equipment and vents.
Saddles are built to divert water around units to prevent ponding on metal roof systems. The self-conforming ability of NCFI sprayed urethane and liquid roof coating work ideally on domed and other curved roof surfaces.
| Feature | Benefit |
|---|---|
| Double Insulation Efficiency | Other materials require twice the thickness for the same insulation. |
| Seamless Effeciency | Sprayed foam creates a monolithic coat which has less heat loss than jointed insulation. |
| Self-Adhering | Sprayed urethane foam self adheres to clean dry surfaces |
| Energy Savings | NCFI foam insulates the roof deck from the heat of the sun and chill of ice keeping it's movement to a minimum, therefore avoiding splits in the roof. |
Performance studies and research suggest that SPF roofing systems can last 30 years or more. Additionally, they require low maintenance, are resistant to leaks caused by hail and wind-driven debris, are resistant to high wind blow-off, can add structural strength, and minimize moisture damage within the building envelope.
The principal causes of premature roof failure are moisture intrusion and lack of wind resistance. Moisture accumulation in roofing systems leads to dripping, accelerated failure of the insulation and membrane, roof structure deterioration, depreciation of assets, and poor thermal performance. SPF roofing systems limit moisture intrusion because of their 90% closed cell properties. Damage to the system typically does not cause leaks into the building, and moisture intrusion is isolated to the areas of damaged foam cells.
In conclusion, SPF roofing systems demonstrate significant sustainable characteristics. SPF roofing systems have a long life, are renewable, save energy, add durability to buildings, and control moisture in buildings.
The use of SPF systems can significantly affect the durability and climate control of a building. Three SPF systems are used within the building envelope: high density (1-1/2 to 2 lb./cubic foot), low density (less than 1/2 lb. per cubic foot), and sealant foams. High density SPF is used when strength, high moisture resistance, and high insulating value are desired. Low density SPF is used when insulation, air barrier, and sound control are desired. Sealant foams are used to caulk around windows, doors, sill plates, and other locations to seal against unwanted air infiltration.
GenFlex Roofing Systems feature two single-ply EPDM membranes: GenFlex EPDM, an elastomeric membrane and Genflex FRM, an EDPM membrane with a tough polyester reinforcement. Both are designed for ultrahigh, long-term performance. EPDM's outstanding elongation characteristics resist extreme temperatures without splits or cracks, while maintaining structural integrity.
Installation systems include ballasted, fully-adhered, and a number of mechanically-attatched alternatives. Components include roofing tapes, bonding adhesive, sealants, flashing and applicable rooftop accessories.
This is a high-performance membrane, highly resistant to tears, impacts, punctures and normal roof traffic. Normal structural movement has limited effect on it's integrity. This membrane provides excellent resistance to ozone and ultraviolet light exposure.
TPO membrane is a high quality thermoplastic polyolefin that offers the "best of both worlds"...the proven flexibility and weathering resistance of rubber and the performance of hot-air welded thermoplastic seams. The top ply features a relatively smooth finished surface that resists the accumulation of dirt, wind blown debris and biological growth, plus the white TPO meets EPA and DOA Energy Star requirements which can reduce energy consumption and heat buildup.
| Fiber Reinforcement | Heat-Weldable | Advanced Compound & UV Technology |
|---|---|---|
| Excellent dimensional stability | Superior seam strength | Resistance to ozone |
| Greater tear & breaking strength | Less seaming labor | Excellent long-term flexibility |
| Outstanding lay flat qualities for easier seaming | VOC free | Contains no compounds that support algae or fungi |
| Increased puncture resistance | Lower labor cost | Scuff resistant |
Unlike other roofing systems, when using spray-on polyurethane foam (SPF), the material literally goes up the wall, curb, or roof-mounted penetrations. Flashing sheets and fasteners are not required.
While flashing details are the most are the most likely cause of roof leaks in virtually all roofing systems, they are often overlooked during the membrane selection process by the roof owner and the consultant and architect. Most conventional systems utilize metal, bituminous, or polymeric membrane to solve a variety of flashing details. Sometimes the roofing contractor relies on experience to field manufacture the proper solution to the problems.
All SPF details are essentially field manufactured. This allow for an easier seamless transition around roof-mounted equipment, parapets, and roof penetrations. The spray application allows for thicker applications to slope away from potential leak problems, such as walls or penetrations. After the application of foam, the protective coating usually extends 4 to 6 inches up penetrations and vertical walls.
Spray foam has the unique ability to adhere to virtually all exterior building materials. Spray polyurethane foam, when correctly applied to surfaces and then coated, does not require metal counterflashings.
Up until now, most residential and commercial insulation needs have been met with the old stand-by, fiberglass insulation. Technology and the trend toward energy conservation have caused us to look elsewhere for a superior, more reliable insulating solution. That solution is found in Spray-in-Place Polyurethane Foam (SPF). Unlike fiber insulation, SPF is highly resistant to water and water vapor, and it retains its insulation effectiveness indefinitly. Rigid polyurethane foam has been called "super insulation" because, inch for inch, it provides almost one-and-a-half to three times the insulation value of any other insulating material.
Polyurethane foam decreases your energy expense by limiting the amount of heat that is lost through your walls. This is due to the fact that spray-in-place polyurethane foam is 90% closed-cell. 70% of heat loss from conductance is stopped by one inch of SPF. The second inch of foam stops about 90% of heat loss and the third inch is going to stop 95% and so forth. SPF is also going to prevent nearly 100% of heat loss through air infiltration with the first one-fourth inch of applied foam. Studies show potential energy savings of twenty to forty percent. In this era of ever-increasing energy expenses, why not insulate your building with the solution you can count on, Spray-in-Place Polyurethane Foam.
