If you are a business owner, nothing is more exciting than designing your own commercial building. This gives you the ability to make your commercial building look unique. The only problem you may run into with a non-standard design is the type of roofing you will use. Some of the standard commercial types of roofing do not work well with non-standard building designs. Do not worry, spray polyurethane foam roofing will not only fit on any type of design you have, but it may even give you a better R-value than some of the other products out there.
What Is Spray Polyurethane Foam Roofing?
Sprayed Polyurethane Foam Roofing (SPF) is constructed from of a combination of isocyanate and polyol, which are both polyurethanes. These two components go through two separate heating chambers, which not only heats the materials, but feeds them into the chamber of the spray gun. Once in the spray gun, they react, and mix together to form a foam. Once in this form they are ready to be sprayed onto your substrate. When the foam reaches the substrate, it continues to expand to many times its original size, where it forms a rigid plastic layer.
Although your SPF goes on as a foam, for the best results your substrate needs to be free from any type of dirt, oil, or other contaminants for your foam to adhere the best. Once the foam is applied and it dries, or is cured, a protective elastomeric top coat is also sprayed or rolled on. This top coat will expand, or contract, based on temperature changes that take place in your foam throughout the day. This top coat will also help to protect your roofing from harmful, and damaging UV rays, as well as give it another layer of moisture resistance.
Advantages Of Spray Polyurethane Foam Roofing
SPF roofing offers many advantages over other styles of roofing.
- As already stated, SPF goes down as a liquid. This means that you are able to achieve seamless coverage, with no gaps, holes, or potential for leaks.
- Due to the foam expanding to cover any surface once it is sprayed, it can cover any shaped roof, or surface. This means that you will be able to cover any irregular shaped spaces, or outcropping that may be present on your roof's surface.
- It is light weight. SPF usually weighs less than half of other traditional methods. This makes SPF a great choice when overall weight is an issue.
- Due to it adhering to your substrate, wind and rain are not able to get underneath your material. This means that it holds up better in storms.
- It is easy to repair. If it is damaged, or gouged by hail, tree branches, or other items, it can easily be repaired with an elastomeric sealant that is designed for this reason.
- It requires minimum upkeep. Less maintenance means less maintenance costs.
Why It Offers Superior Insulating Qualities
One of the biggest advantages that SPF has over traditional types of roofing materials is the superior insulation value that it offers. Because it is constructed from closed cell insulation, it is much denser, which in turn gives it a higher thermal resistance, or R-value, than other types of materials.
In the case of SPF, it will block all three types of heat transfer. These three types are:
- Conductive heat transfer
- Radiant heat transfer
- Convective heat transfer
By blocking the transfer of all types of heat, SPF will keep your energy in your building where it belongs. This also means that it will help to lower your heating and cooling costs. This is money that will help to pay for the costs of your roofing.
No matter which type of architectural style you are considering for your building, you owe it to yourself to consider the advantages that SPF roofing can offer. You may be pleased with what you find. Click here for more information.
