Role Of Thermoplastics & Bitumen in Single Play Roofing


Single ply roofing is one of the most preferable roofing among home and business owners. It offers many benefits over traditional BUR (built up roofs). The life expectancy of this roofing is up to forty years. It does not only provide strength and durability, it is eco-friendly and comes in different materials and colors.  Single ply roofing systems offer the advantages of rapid installation and lightweight construction. They have the ability offering high puncture and tear resistance, high tensile strength and have excellent dimensional stability. They are capable of resisting ozone and UV exposure, extreme weather conditions, chemicals, and fire. During installation, heavy equipment is not required and the membrane can be applied during inclement weather.

Single Ply roofing is a flexible or semi-flexible, per-manufactured membrane. It is made of rubber or plastic materials. These days three major categories play a vital role in Single Ply Roofing. These are Thermoplastics and Modified Bitumens.


Thermoset membranes consist of rubber polymers, the most common of which is EPDM (ethylene-propylene-diene-monomer). Thermoset membranes have found widespread success as roofing materials. Due to their and excellent resistance to ultraviolet light (UV), ozone, and chemicals found on roofs.


Thermoplastic membranes:

Such membranes are based on plastic polymers. Most thermoplastic membranes are manufactured to include a reinforcement layer, polyester or fiberglass. It provides increased strength and dimensional stability. The thermoplastic membrane is PVC (poly-vinyl-chloride) which combines excellent weathering characteristics, high tensile strength, and long-term durability. It offers resistance to harsh chemicals and industrial pollutants.It provides a strong, watertight seal and results in a clean, fast, and economical installation.

Modified bitumen membranes;

These membranes are hybrid products that combine the high tech formulation and prefabrication benefits of single-ply.  These materials are factory-fabricated layers of asphalt. Then “modified” using a rubber or plastic for increased flexibility. All these are combined with a reinforcing agent for added strength and stability. APP (atactic polypropylene) and SBS (styrene butadiene styrene)are the modifiers these days.

Single ply roofing systems have given assurance to all contractors and building owners that their roofing material can secure the roofs in severe weather. This gives confidence to the owners that their investment will be protected for many years. These systems are the best choice these days with all the characters within like UV stabilization, energy efficient and high tear and puncture resistance. In recent years, after combining all this with ease of installation and simple repairs, it’s easy to see why single-ply roofing products have become so popular. Which product you should use depends on many factors like cost, wind exposure, building height, anticipated roof traffic. With several product choices in the single-ply category, it is wiser to consult with a qualified commercial roofing installer to see which option is the best.
