Choosing the Right Vinyl

CALENDERED:

Calendered vinyl is rolled out from a putty-like state into a thin sheet similar to process of making pasta. It requires less production space and can be manufactured more efficiently in large quantities. Compared to cast, it is the thicker option ranging between 3-6 mil. As it ages and is exposed to weathering conditions, calendered vinyl tends to shrink back to its original form causing peeling around the edges. Manufacturers have developed variations by adding anti-shrinking agents in this vinyl to reduce retraction, offering a more efficient variety of high-quality calendered vinyl. Typically it yields a life expectancy of 3-5 years.

Calendered vinyl is much more affordable and a practical solution for indoor applications, flat projects with little stretch, or projects requiring a shorter service.

CAST:

Cast is poured into molds when hot and cooled into ultra-thin sheets, 1.5-3 mil. This production requires additional room for molds and increases time between production for cooling. These conditions result in higher production costs. Being formed in a flat mold, yields a product that maintains its flat shape throughout its life and is less likely to shrink, lift or pull away from the application surface. Cast vinyl is expected to last between 7-10 years, nearly doubling the lifespan of calendared products.

Cast vinyl, while more expensive than calendered, is recommended for outdoor applications with surfaces frequently exposed to heat. It is good for projects with movement and detail and for applications needing a longer life expectancy.
