What does TPO membrane stand for?
What does TPO membrane stand for?
Thermoplastic polyolefin
Thermoplastic polyolefin (TPO) single-ply roofing membranes are among the fastest growing commercial roofing products and have gained praise across the industry for their many performance and installation advantages.
What is TPO waterproofing membrane?
TPO is acronymous for Thermoplastic Polyolefin and it is a type of polymer single-ply membrane that uses thermo-welding (hot air) to connect the seams. This type of membrane was originally developed in the 80’s and it is currently the fastest growing membrane in the roofing and waterproofing industry.
What spec section is TPO roofing?
SECTION 07 54 23 ADHERED THERMOSPLASTIC POLYOLEFIN (TPO) ROOFING PART 1 – GENERAL 1.01 SECTION INCLUDES: A. The Work specified in this Technical Specifications Section consists of providing Adhered TPO roofing as required to complete work.
What thickness is TPO roofing?
TPO is a type of roofing membrane that can come in a variety of thicknesses. The most common thickness is probably 60 mils. (A mil is a unit of measure where 1-mil is equal to 0.001 inches. So, a 45-mil roofing membrane is actually 0.045 inches thick; whereas a 60-mil membrane is 0.06 inches thick, and so on.)
Is TPO roofing waterproof?
If you’re curious about TPO waterproofing membrane specification. Here’s where the magic happens: a TPO’s hot air-welded seams make it 100% resistant to water penetration. Unlike PVC, property owners enjoy a leak-proof roof for a long period of time.
What is the difference between a TPO and PVC roof?
TPO roofing membranes consist of an ethylene or polyethylene thermoplastic bound to ethylene propylene rubber. PVC roofing membranes are made by polymerizing vinyl chloride monomers, then adding plasticizers to increase flexibility.
What is maximum slope for TPO roofing?
The maximum recommended roof slope for Mechanically Attached Roofing Systems is 18″ in one horizontal foot. There are no maximum slope restrictions for the application of the Fully Adhered Roofing System.
What is the minimum slope for a TPO roof?
Thermoplastic single-ply roofing systems are plastic sheets (PVC, TPO, CSPE) that are welded together with hot air. This creates a shingle sheet that provides the weather protection for the building. Both the Thermoset and the Thermoplastic must be installed at a minimum one- fourth-inch-per-twelve-inch slope.
How thick is 80mpo TPO?
0.080 inch thick
WeatherBond TPO is 0.080 inch thick white, reinforced single ply roofing membrane.
What is the R value of 60 TPO?
A single-ply roofing system (TPO or EPDM) has a 0.24-0.33 R-value with a typical installed thickness level, therefore you’ll need considerable thickness of insulation to get you to an R-30.
