I've come across a few different facers on rigid polyiso:
- trilaminate (foil-kraft-foil)
- glass fiber
- reflective vs non-reflective
Based on the manufacturers guidelines, I've seen recommendations based on wall construction and siding materials, but I don't understand the reasoning behind these guidelines.
How important is it to match the facer to your building context?. What's the difference, performance-wise? In what situations would you use one over another?
Any help will be greatly appreciated.
