Polyurethane Foam Roofing – Top Insulation And Waterproofing Qualities
Polyurethane foam roofing has been around for much more than 40 years as one particular of the main possibilities for supplies in insulation and roofing. Once, they had been regarded as only to be an alternative to the age-old built-up roofing but now polyurethane foam roofing already belongs to the forefront of the roofing market as it has proven its durability, dependability and affordability. Some have already withstood 40 years and seem to be able to continue performing for the decades to come.
Good Advantages of Polyurethane Foam Roofing
Polyurethane foam roofing has various good advantages when compared to other roofing options. The coverage of this variety of roofing is seamless, as polyurethane foam comes in liquid type at initially, and then sprayed evenly as a single, continuous membrane that protects the whole roof. There are no joints or seams that can widen to result in leaks like in other roofing components. Polyurethane foam is also versatile, it can be installed in practically any type of surface even roofs with protrusions and irregular shapes can be covered by polyurethane foam.
Polyurethane foam roofing is also very lightweight, it normally just weighs around 50 pounds per square feet, compared to 800 pounds for the built-up roofing method and at least one hundred pounds for those ballasted single-ply membrane roofs. Polyurethane foam also gives excellent insulation so it can assistance preserve heat away throughout hot seasons and heat inside in the course of cold seasons. This type of roofing is also pretty easy to retain, there is little waste made all through its use, and with proper upkeep, can final indefinitely.
Insulating Properties
The insulating properties of polyurethane foam roofing are incomparable. For such a thin material, it can give sufficient thermal resistance like no other roofing selection. For each and every 1 inch of polyurethane foam roofing, the R-value is rated at 7.14. This can support save as much as 30% of energy expenses for each cooling and heating.
With such savings, the price of the roofing can be recovered easily inside just 5 years. These insulating properties have verified to be helpful in wineries, chemical processing plants, and oil refineries. If polyurethane foam roofing can withstand the demands of these industries, how significantly more can it give less demanding settings?
Waterproofing
A further critical property of polyurethane foam is its waterproofing capabilities. Polyurethane foam roofing is comprised of extremely uptight cells that as a whole can act as a barrier for both water and moisture. Not only does it maintain water, in liquid type, away, it also minimizes difficulties with dew point and prevents condensation of water inside structures.
The roofing is pretty substantially protected even if the foam’s major coat gets broken as the underlying layer nonetheless keeps the roof waterproof. Water also drains correctly so accumulation of water does not happen even when it rains.
How It is Applied
Polyurethane foam roofing is truly a mixture of polyol and isocyanate. secondary containment coatings are run through a machine identified as the proportioner that heats up the two chemicals and sprays them in a mixture applying a spray gun as a single substrate. Since the foam is initially sprayed in liquid type, it can cover the surface of a structure as a single, continuous layer that has no seams or joints, delivering stability and even coverage.
When installing the polyurethane foam roof, it is crucial for the surface to be dry and cost-free of any contaminant such as solvents and oil. To protect the polyurethane foam roof from the rays of the sun, a different layer, named the elastomeric coat is sprayed on major, producing the roof even far more protective as it is.
With such fantastic advantages and ease of installation, there is no wonder why polyurethane foam has turn out to be one particular of the major options amongst roofing selections currently. With such great properties there is no query that polyurethane foam roofing is certainly worth having for any structure that demands adequate protection.
