A designer asked: is it acceptable to use a Crib 5 interliner with a Crib 3 fabric in a restaurant?

The short answer is no. In non-residential spaces an interliner does not compensate for a fabric that does not meet the required fire standard. The Crib 5 interliner and Crib 3 fabric combination would not be acceptable in a restaurant or any other public space. The fabric itself must either be inherently Crib 5 or be treated to achieve Crib 5.

This combination might be acceptable in an office environment where Crib 3 is the required standard, but not in a public-facing hospitality environment.
