Tpo vs pvc roofing.
How to tell whether a roof is pvc or tpo.
A tpo roof if installed properly can cover the top of a parapet similar to a pvc roofing membrane.
Tpo is thin compared to other membranes usually around 1 1 2 millimeters in thickness.
Two of the hardest flat roof systems to tell apart is the pvc roof and the tpo roof.
The top ply contains additives that make the membrane uv resistant.
That is why it can cover the top of the parapet more easily than a tpo membrane.
Polyvinyl chloride pvc used since the 1960s pvc membranes are popular for their easy installation and cheap cost.
It is typically white in color and has a rubbery feel.
Similarities of tpo and pvc roofing membranes.
Pvc roof material is composed of two layers of pvc with a polyester reinforcement scrim in between.
If you are up for a more chemical resistant roofing and are looking for a cost friendly option pvc.
The biggest differences are your pvc roof is more fire resistant than a tpo membrane and is more resistant to uv from the sun making it less brittle over time.
The top layer is typically white to reflect as much heat as possible but several colors are available and contains plasticizers making the sheet flexible.
When it comes to a durable roof that is also environment friendly tpo roofing is a great option.
When being attached to the roof material it is either nailed or glued on.
However while the face of both membranes and their installation are virtually identical they are very different systems on the inside.
