Closed-Cell Spray Polyurethane Foam (ccSPF) in commercial insulation and roofing applications. These are common questions about ccSPF that we have compiled here. Enovate is a new state-of-the-art insulating technology we developed for expanding rigid plastic into closed-cell foam insulations. Enovate is a non-flammable liquid/gas that greatly improves the physical properties and insulating characteristics of today’s insulation systems.
What are the climates and conditions where a sprayed polyurethane roof cannot/should not be applied?
Spray foam roofs are just like all other roof systems; they need to be applied to a clean and dry substrate. Spray foam roofs can be installed in most regions of the world.When applying spray foam to roofs, it is recommended for best results that the ambient air temperatures range between 40 - 100 degrees F and that wind conditions are less than 12 miles per hour (or 25 miles per hour when wind screens are being used). For best results, it is recommended that humidity levels are below 80% at the point of application. These general rules of thumb are true for most commercial roofing systems, regardless of their type, if you want to follow good, safe roofing practices.
Closed-cell spray polyurethane foam is considered a thermal, moisture, air and vapor barrier all in one.
It is quick and easy to apply to a wide variety of substrates and conforms to uniquely shaped structures and difficult-to-flash penetrations. SPF roofs help reduce dependency on oil, they conserve energy natural resources, and they reduce total energy consumption. They also have no ozone-depleting effects or Volatile Organic Compounds. They are sustainable because they never need to be replaced if properly maintained.
As a result, the roofs never need to be removed or end up in a landfill. SPF roofs and walls are watertight within 10 seconds of being applied to a dry clean surface. They are able to bear foot traffic within 30 seconds of being applied.
Yes it has. We’re proud of the fact that we received an EPA Stratospheric Ozone Protection Award in 2002.
SPF systems allow contractors to save money on both labor and insurance due to reduced crew size, increased production rate and ease of flashing. SPF roofs allow a contractor to finish a job under budget and ahead of schedule.
SPF can save the building owners time and money because it is applied quietly and efficiently without any disruption or downtime. SPF is extremely energy efficient which saves on heating and cooling costs.
Honeywell’s Enovate is a very energy-efficient insulation choice available today for commercial building. Closed-cell spray foam insulation formulated with Enovate provides superior thermal properties. Spray foam is 26-32% more energy efficient than a comparable boardstock insulation with an equal R-value (when you consider spray foam’s improved low temperature R-values and reduced energy loss at insulation joints and fasteners, which significantly lowers your heating and cooling costs). Spray foam’s increased energy efficiency, along with a Zero Ozone Depletion Potential, makes spray foam with Enovate a valuable solution for a building owner. In addition,
Enovate is not considered a VOC (Volatile Organic Compound) and is non-flammable. In recognition of the fact that Enovate does not have an effect on the ozone layer, the Environmental Protection Agency (EPA) awarded Honeywell its Stratospheric Ozone Protection Award in 2002. Spray foam roofs are an excellent choice for those seeking Leadership in Energy and Environmental Design (LEED) Green Building Rating System Certification. A spray foam roof with a highly reflective white surface provides superior reflectivity and emissivity properties. These features offer considerable savings for building owners for energy usage associated with heating and cooling, abate urban heat islands, and help slow the formation of smog-forming pollutants. Spray foam roof manufacturers are listed in the Energy Star Roof Products program. Studies at Oak Ridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) document the energy and reflective performance savings from spray foam roof systems. Spray foam roofs are listed in the Energy Star roof products program.
The U.S. government National Standards and Technology (NIST) agency documents spray foam roof systems as having excellent performance compared to other roof systems after hurricane Katrina and Rita.
The US Energy Labs at Oak Ridge define sustainable roofs as addressing energy efficiency, low environmental impact, and durability with less maintenance and reduced waste generation through the design, construction, reuse and final disposal stage.
Closed-Cell Spray Polyurethane Foam (ccSPF) in commercial and industrial insulation wall and roofing applications Common questions about ccSPF for wall and roof applications They are listed at Underwriters Laboratory and have Factory Mutual approval.
In many instances it can be less expensive and reduce both installation time and cost for the building owner. Closed-cell spray foam both insulates and waterproofs at the same time, using the most advanced building insulation technology. Since it is spray applied, it can be tailored for draining water and creating a slope on a flat roof.
A typical spray foam application for new construction typically costs $1.80 to $2.25 a square foot, depending on local wage rates, contractor's insurance coverage, job site conditions and local market conditions.
Depending on your roofs' condition and job site conditions (i.e., penetrations tear off, etc.), the cost for a re-roofing project is approximately $4 to $6 a square foot. This is very competitive against other types of commercial roofing systems.
It is important to ask each manufacturer about their specific warranty language, however, many offer “Unlimited Wind Warranties” to protect building owners in severe weather events.
A roof incorporating Honeywell Enovate can decrease energy expenses compared to alternative solutions because of its advanced state-of-the-art insulating properties and its ability to be combined with a wide variety of highly reflective white surfacing materials.
They offer the highest R-value per inch of any insulation. 3-lbs density roofing foams have an
R-value of 6.7 per inch and 2-lbs wall foams have an R-value of 6.2 per inch. SPF Spray Polyurethane Foam roofs are backed by manufacturers "No Dollar Limit" warranties for up to 20 years and the warranty can be renewed and extended indefinitely in 10 year increments, if manufactures recommendations and extension procedures are followed.
Spray polyurethane foam roofs are installed quickly and easily, with minimum business interruption or inconvenience to the building owner, in comparison to installation of traditional roofing systems.
Studies at Oak Ridge National Labs (ORNL) and Lawrence Berkeley National Laboratory (BNL) document the energy and reflective performance and savings from spray foam roof systems.
Spray foam roof systems are backed by manufacturers’ warranties for periods of 5, 10, 15, and 20 years in duration. Many of the spray foam manufacturers will also provide extended warranties beyond the initial warranties outlined above based on a re-inspection, and provided that any alterations and deficiencies in the roof system are addressed, bringing the roof back to a warrantable condition. Spray foam roofs are easy to maintain and repair. When properly maintained and recoated per the manufacturer's recommendations, they should last as long as the structure. The US Energy Labs at Oak Ridge define sustainable roofs as having the following characteristics: they address energy efficiency; they have a low environmental impact; they are durable with less maintenance; and there is reduced waste generation through the design, construction, reuse and final disposal stage. A spray foam roof addresses these issues. In most instances, repairs and maintenance are made using simple caulks and a coating.The return on investment (ROI) begins the day the new spray foam roof is installed, due to the energy savings from reduced heating and cooling costs.
Closed-cell spray polyurethane foam roofs and walls are recognized for their excellent severe wind performance capabilities as demonstrated by the US Government National Institute of Standards and Technology agency report after hurricanes Katrina and Rita in 2005. Many spray polyurethane foam systems applied over concrete decks have a FM (Factory Mutual) I-990 wind uplift rating and exceed FM's test equipment capabilities for wind testing.
They are listed in the ENERGY STAR roof products program, contribute to USGBC LEED green building rating system certification points, and are noted for their excellent severe wind performance capabilities in the US Government National Institute of Standards and Technology agency report after hurricanes Katrina and Rita in 2005.They are listed at Underwriter's Laboratory and have Factory Mutual approval.
"Hail Leak" warranties are available with SPF roofs. It is important to contact the manufacturer to get their hail protection specifications and specific warranty language.
The weight of a spray polyurethane foam roof is determined by its thickness. Typically one (1”) inch weighs less than ½ pound per square foot installed.
SPF roofs are fully adhered with no penetrating fasteners, they attach easily to all types of decks and substrates.
When the Louisiana Superdome’s roof was destroyed by Hurricane Katrina in August of 2005, it was replaced with a SPF roof. The system, which utilizes Enovate insulating technology from Honeywell International, played an integral part in the quick turnaround. After Katrina, the state wanted a roof that would hold up against future storms. Having used SPF roofs on other state projects they were familiar with its performance under adverse weather conditions. These factors, along with guarantees and warranties offered by SPF roofing manufacturers, energy savings potential and sustainability helped the state of Louisiana make its decision.
