Astm d4434 standard specification for poly vinyl chloride sheet roofing astm d6878 standard specification for thermoplastic polyolefin based sheet roofing warranties when purchasing a new roof system there will be two warranties to consider.
Thermoplastic polyolefin single ply roofing.
What are single ply membranes.
This membrane is composed of three layers.
Tpo roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.
The tpo membrane was first introduced to the roofing market in the early 1990 s as a more economical and efficient alternative that was thought to replace pvc roofing products.
Cost a typical residential tpo roof will cost between 6 50 and 11 50 per sq.
Thus for an average sized 1 200 sq.
Thermoplastic polyolefin is a single ply roofing membrane that is one of the fastest growing commercial roofing systems on the market.
Clearly seam strength is the most critical factor in the watertight integrity of the roofing system.
Flat roof your.
To understand why tpo membranes are the fastest growing segment of the membrane market a little background is in order.
Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price.
Tpo based products have been available since the 1980s.
Referred as elastomeric roofing systems these membranes are available in form of sheets.
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.
Therefore it s like having a single uniform membrane covering your building from one edge of the roof to the other.
If you are looking for a cost effective and durable single ply roofing system for your flat or low slope roof a tpo thermoplastic olefin membrane may be a solid energy efficient option.
These systems are generally categorized as thermoset and thermoplastic membranes.
For commercial properties single ply roofs are mostly preferred because of their strength and resistance to various types of damage.
Tpo s long term heat uv and natural fungal resistance plus flexibility without need for plasticizers also make tpo a reliable low slope roofing system.
By 1993 the earlier non reinforced membranes were replaced by fabric reinforced sheets the version available today.
What is tpo roofing.
The first sheets for membrane roofing were introduced in 1989.
Heat welded seams provide superior strength.
In the building trades the acronym tpo stands for thermoplastic polyolefin a material originally developed for pond liners and used extensively for roofing since 1989 it s a single ply membrane made from a polymerized combination of polypropylene and ethylene propylene rubber that can be attached to a roof with adhesive or with mechanical fasteners.
Tpo is a single ply roofing system that consisting of a thermoplastic polyolefin membrane.
