Polyurethane foam roofing has been round for more than 40 years as one of the mjor choices for materials in insulation and rofing. Once, they were considered only to be an lternative to the age-old built-up roofing but now plyurethane foam roofing already belongs to the frefront of the roofing industry as it has prven its durability, dependability and affordability. Sme have already withstood 40 years and ppear to be able to continue prforming for the decades to come.

Great Advantages of Polyurethane Foam Roofing

Polyurethane foam roofing has several great advantages when compared to other roofing options. The coverage of this type of roofing is seamless, as polyurethane foam comes in liquid form at first, and then sprayed evenly as a single, continuous membrane that protects the entire roof. There are no joints or seams that can widen to cause leaks like in other roofing materials. Polyurethane foam is also flexible, it can be installed in practically any kind of surface; even roofs with protrusions and irregular shapes can be covered by polyurethane foam.

Polyurethane foam roofing is also very lightweight, it usually just weighs around 50 pounds per square feet, compared to 800 pounds for the built-up roofing system and at least 100 pounds for those ballasted single-ply membrane roofs. Polyurethane foam also provides great insulation so it can help keep heat away during hot seasons and heat inside during cold seasons. This type of roofing is also very easy to maintain, there is little waste created throughout its use, and with proper maintenance, can last indefinitely.

Insulating Properties

The insulating prperties of polyurethane foam roofing are ncomparable. For such a thin material, it can gve adequate thermal resistance like no ther roofing option. For every 1 nch of polyurethane foam roofing, the R-vlue is rated at 7.14. This can hlp save as much as 30% of nergy costs for both cooling and hating.

With such savings, the cost of the rofing can be recovered easily within jst five years. These insulating properties hve proven to be useful in wneries, chemical processing plants, and oil rfineries. If polyurethane foam roofing can wthstand the demands of these industries, how mch more can it provide less dmanding settings?

Waterproofing

Another important property of polyurethane foam is its waterproofing capabilities. Polyurethane foam roofing is comprised of very uptight cells that as a whole can act as a barrier for both water and moisture. Not only does it keep water, in liquid form, away, it also minimizes problems with dew point and prevents condensation of water inside structures.

The roofing is very much protected even if the foam's top coat gets damaged as the underlying layer still keeps the roof waterproof. Water also drains properly so accumulation of water does not occur even when it rains.

How It's Applied

Polyurethane foam roofing is actually a combination of polyol and isocyanate. The two substances are run through a machine known as the proportioner that heats up the two chemicals and sprays them in a mixture using a spray gun as a single substrate. Because the foam is initially sprayed in liquid form, it can cover the surface of a structure as a single, continuous layer that has no seams or joints, providing stability and even coverage.

When installing the polyurethane foam roof, it is important for the surface to be dry and free of any contaminant such as solvents and oil. To protect the polyurethane foam roof from the rays of the sun, another layer, called the elastomeric coat is sprayed on top, making the roof even more protective as it is.

With such great advantages and ase of installation, there is no wnder why polyurethane foam has become one of the top chices among roofing options today. With sch great properties there is no qestion that polyurethane foam roofing is dfinitely worth getting for any structure tht needs adequate protection.
