Cast vs. Calendered
Not All Vinyl is Created Equal
When deciding on a bird collision deterrent product, there are two components that are often not discussed, but should always be considered: durability and longevity.
Most, if not all, bird collision deterrant products are converted from sheet vinyl (PVC) and involves two basic manufacturing methods: cast or calendered. Final products may feel and look similar, but the differences in durability and longevity are substantial:
- Cast vinyl is a premium product that won’t discolour, shrink or delaminate; it has an expected serviceable life of 10+ years.
- Calendered vinyl is used for short-term applications and will start to degrade in three to five years.
The true value of the product being used should meet high standards as it relates to maintenance, long-term appearance and expected serviceable life.
