Code Quick Reference
The International Residential Code (IRC) requires a minimum guard height of 36 inches for residential decks, balconies, and porches that are more than 30 inches above grade. Our 33.6" glass panels + spigot meet this requirement at 36" total installed height. Note: Some states (such as Massachusetts) may require 42" for all occupancies — always verify with your local building department.
The International Building Code (IBC) requires a minimum guard height of 42 inches for commercial occupancies, multi-family buildings, and public spaces. Our 39.6" glass panels + spigot meet this requirement at 42" total installed height.
Glass used in railings must be safety glazing per CPSC 16 CFR 1201 and/or ANSI Z97.1. All our panels are 12mm fully tempered safety glass meeting ASTM C1048 standards. Tempered glass is required in locations where breakage could result in falls or cutting injuries.
Yes. Florida has the strictest wind load requirements in the US. High-Velocity Hurricane Zones (HVHZ) in Miami-Dade and Broward counties require Miami-Dade NOA or Florida Product Approval. Wind-borne debris regions require impact-rated glass. Design wind speeds range from 130 mph inland to 180+ mph on the SE coast and Keys. Contact us with your project address for verification.
Pool barrier requirements vary by state but generally follow the International Swimming Pool and Spa Code (ISPSC): minimum 48" height, no climbable features, self-closing/self-latching gates with latch releases no higher than 54" above grade. Our 48" glass panel system with self-closing gate hardware is designed to meet these requirements. Check your local code for specifics.
Some jurisdictions require engineered drawings stamped by a licensed PE for glass railing installations, particularly for commercial applications. This is mandatory in NYC and common in Florida. If your permit application requires engineering documentation, contact us — we can connect you with engineering resources familiar with our systems.
