Why Spray Foam Roofing?
For roofing applications that require added insulation or have complex surface areas, McCormack offers Spray-in-Place Foam (“Spray Foam”) on commercial buildings. Spray Foam is a modern, more environmentally friendly alternative to traditional built up or tar and gravel roofing solutions.
Benefits Of Spray Foam Roofing
For applications that require the best insulating properties, spray foam offers some of the highest quality and cost effective solutions in the market. Sure to its durability and energy savings, the benefits of spray foam are vast.
Spray Foam Roof benefits:
- Quick application
- Energy efficiency
- Long lasting
- Easy to maintain
A Proven Track Record
Spray Foam roofs can last 50+ years with proper maintenance, making it a great sustainable option for your next project
Here are some of the ways spray foam can be applied:
Spray Foam On The Exterior Of A Building
Spray Foam is an optimal roofing system for many flat and low-slope applications. The main advantage of a Spray Foam roof system is that not only is it a roof, but it is a great insulator, something traditional roof systems are not. As with Spray Foam in walls, a Spray Foam roof can start paying for itself immediately in energy and HVAC savings.
Spray Foam also has its advantages when it comes to serving as a rain barrier. It is essentially installed as a single piece without seams. Therefore, it is less likely to breakdown and allow water intrusion.
Finally, Spray Foam also has many environmental benefits. It is extremely light weight and can often be applied over existing roof materials without costly tear offs or displacement of roofing felts that may contain asbestos. Spray Foam roofs can be classified as “sustainable” because, with proper care and periodical recoating, they can last more than 50 years. Most other roof systems last no more than 20 years.
Spray Foam Roof Top Coating
Part of a Spray Foam roof system is the elastomeric or silicone top coating. With the proper ENERGY STAR® coating McCormack can help you meet your Title 24 Cool Roof requirements on your commercial property. A Cool Roof reduces the amount of heat absorbed by your building allowing further savings in HVAC and energy costs.
Spray Foam Within The Building
In addition to serving as a roofing barrier, Spray Foam can be used underneath a roof to seal cracks within a building and provide further insulation. Spray Foam offers a higher thermal resistance (R-value) compared to other traditional interior insulation materials, such as fiberglass or cellulose, and can be sprayed into areas that are difficult for other materials to cover.
With Spray Foam the underside of roof sheathing in attics and in subfloor crawlspaces can be completely insulated. Spray Foam insulation acts as an air barrier sealing off the hundreds of often imperceptible cracks and crevices. Traditional insulating materials can’t do that. Because Spray Foam seals the building envelope, its R-value holds true. Fiberglass and cellulose rarely attain the R-value claimed because of air leakage in real-life applications.
Used correctly in a new build, remodel or retrofit, a Spray Foam insulated building can use smaller Heating Ventilation and Air Conditioning (HVAC) units, producing substantial long-term savings. Polyurethane Spray Foam Insulation can actually pay for itself over time with these savings.
A Sustainable Solution
FiberTite offers one of the most environmentally conscious roofing solutions for commercial buildings.
| Longevity | FiberTite is engineered to withstand severe weather, extreme temperatures and harsh chemicals. It is designed for durability and longevity. As such, the carbon footprint of the long lifecycle of these products is much lower than that of less durable options. |
|---|---|
| Cool Roof System | FiberTite can be installed with certain colors and coatings that have a high solar reflectivity rating, enabling its users to produce a cool roof system. Installing a cool roofing system with high solar reflectivity and infrared emittance is an effective way to easily increase a building’s energy efficiency. |
| LEED Applications | FiberTite installations can be found on a number of LEED-approved buildings nationwide. The LEED Green Building Rating System for New Construction promotes buildings that are not only environmentally responsible in their design, but sustainable and profitable in their operation, and healthy to live and work in. |
| Title 24 Compliant | FiberTite Roofing Membranes Meet the Solar Reflectivity and Infrared Emittance Requirements of California Title 24. |
| Energy Star Leader | FiberTite was one of the first roofing membranes labeled under the ENERGY STAR roofing products program. |
Frequently Asked Questions
Because of its rigid nature and ability to adhere to many materials, closed-cell SPF can provide structural enhancement to framed buildings. Racking strength of certain framed walls, as well as uplift strength of framed roof decks can be significantly increased with the addition of just 2-3 inches of SPF.
Closed-cell foams, by nature, are resistant to water absorption, and are approved by FEMA as a flood-resistant material. Open-cell foams can absorb and retain liquid water at varying rates. It is important to consider the different properties for each foam type for each application.
Spray foam, when applied to certain minimum thicknesses (about 1.5” for closed-cell foam and 3.5-5.5” for open-cell foam) will form an air-impermeable air-barrier material. When properly installed in a well-designed building envelope, SPF plays a key part in creating air barrier assemblies and systems. For more information on air barriers, visit the Air Barrier Association of America (ABAA) at www.airbarrier.org.
SPF roofs systems require a protective coating over the foam to protect it from ultra-violet light and routine surface damage. Depending on climate, the type of coating, and the total coating thickness, these coatings may last from 5 to 20 years. Regular inspections should be performed to determine with a recoating is needed.
