Fiberglass entrances and storefronts?

I am starting to specify fiberglass material, in lieu of aluminum, for entrances and storefronts. Fiberframe and Cascadia manufacture these type of products.

What MasterFormat number would you recommend?

I would create a new Level 3 number under the applicable Level 2 number and call it “Composite Entrances and Storefronts,” “Composite Entrances,” or “Composite Storefronts.”

This aligns with Section 08 54 00 “Composite Windows” that include fiberglass.
