For those working in NYC LPC projects, how do you meet the ASTM E84 requirements for windows. Wood windows don't fall in this category unless they have fire-retardant wood which I doubt most people specify for cost reason. Is there an exception?
I usually specify aluminum and upvc windows for NON-LPC project, but they are not acceptable for Landmark Projects
Code section 806.5 says: Material, other than foam plastic used as interior trim, shall have a minimum Class C flame spread index as described in Section 803.1.1 and maximum smoke-developed index of 450, when tested in accordance with ASTM E 84 or UL 723. Combustible trim, excluding handrails and guardrails, shall not exceed 10 percent of the specific wall or ceiling area in which it is attached.
Definition of Trim in code:
TRIM: Picture molds, chair rails, baseboards, handrails, door and window frames and similar decorative or protective materials used in fixed applications.
