Most vinyl siding products are made to mimic wood which makes for interesting comparisons between the two.
Polypropylene vs vinyl siding.
On average polypropylene siding is twice as thick as traditional vinyl siding.
Vinyl tiles are consequently able to handle higher loads and also have better impact resistance.
Vinyl siding is made from polyvinyl chloride pvc while polymer siding is made from polypropylene resin.
The basic structure of pvc on the other hand contains about 30 weight of the element chlorine.
The increased thickness adds weight to the product making in more wind resistant and therefore far less likely to blow off during a storm.
But they aren t the same thing.
Like vinyl siding polypropylene is another polymeric siding with its own unique quality standard and performance requirements.
These products are often made from polypropylene resin to produce a siding that is thicker and more rigid than polyethylene.
To the naked eye these two differences are difficult to discern which is why you will see both terms used interchangeably even though they re not exactly the same thing.
Because of their similar makeup vinyl and polymer siding are often referred to interchangeably.
Vinyl siding is made of polyvinyl chloride aka pvc.
Note on shingle and shake siding.
The added thickness provides better impact resistance against things such as hail and falling tree branches.
Meanwhile polymer siding is made from polypropylene resin.
Vinyl and polymer siding are both essentially plastic.
It is the nature of the materials that determines how they can be shaped.
These codes require that vinyl siding insulated vinyl siding and polypropylene siding be certified to their respective astm standards.

Vinyl siding vs wood siding.
The difference between them lies in the type of plastic.
If you look at pvc and pp tiles you will probably notice that vinyl interlocking tiles are usually uniform whereas polypropylene tiles tend to have the structure of a grid.
