Polypropylene (PP), also known as polypropene, is a thermoplastic polymer that is quite durable, so it can withstand daily wear and tear, and is resistant to cracking and stress. Polypropylene can be used in a variety of building and construction applications, including: siding, air and moisture barrier membranes, carpet textiles, films and sheets used in insulating building wraps, industrial adhesives and tapes, and plastic parts included in piping.

Some of the benefits of the use of polypropylene in these applications include:

• Energy Efficiency: Building wraps and air and moisture barrier membranes enhanced with polypropylene can decrease air intrusion and heat transfer, increasing a building’s energy efficiency.

• Weather Resistance: Durable siding and air and moisture barrier films and sheets made with polypropylene can help buildings and other structures resist damage from extreme weather like hail and winds.

• Green Roofing Options: Waterproof membranes made with polypropylene are used to create the drainage mats used in vegetative roofing systems.
