SPF (Spray Polyurethane Foam)

SPF roofs have long been regarded as one of the best ways to improve a building’s energy efficiency — as well as mischaracterized as a low-performing roofing system due to the cheap, weak coatings that are often chosen to protect the foam. UV exposure, physical damage, and ponding water take their toll on the coating, and as it deteriorates, so does the roof; you’ll often find large blisters and burn holes as evidence.

Ecodur Roof Coating has no maximum thickness and can cure at the same pace regardless of depth, creating an extremely tough, seamless, waterproof membrane – perfect for filling those large blisters! This makes it ideal for repairing, coating, and revitalizing even the worst-worn SPF roofs.

How To Improve The Initial Lifespan Of SPF Roofs

Coated SPF is a great system for maximizing your building efficiency. However, it's among the roofing products with the lowest expected lifespan and is usually dismissed as a short-term solution. Luckily, you can dramatically improve the initial lifespan of SPF roofs using Castagra's super tough Ecodur+ Roof Coating!

Foam and Cementitious Roof

Spray polyurethane foam (SPF) roofing is a popular choice in hot sunny environments. With R values up to R-6.5 per inch of thickness, an SPF roof can be a very effective way to insulate a building and keep utility costs low. However, SPF itself has no resistance to damage from UV rays and can be ruined in less than 5 hours of direct exposure. While many options exist for protecting SPF from UV exposure, cementitious roofing is one of the longest-lasting and toughest available. Though cementitious roofing offers many benefits, it presents significant challenges as it approaches the end of its life.

Cannabis Facility Roof

Growing cannabis indoors is the easiest way to control environmental conditions and ensure a consistent, medical-grade product. HVAC energy costs are a major consideration for growers, and proper building insulation plays a big role in reducing those costs. Spray Polyurethane Foam or SPF may be the ultimate choice in insulation. With R values of up to 6.5 per inch, it can insulate even better than rigid foam boards. However, as SPF is generally applied over the top of a roofing structure, it must be protected from the elements.

How To Improve The Initial Lifespan of SPF Roofs

The roofing industry is particularly aware of this trend. Roofs can achieve higher efficiency through reflectance, insulation, or through peak performance (a combination of both).
