Is there such a thing as a 1-hour or 2-hour rated skylight?
Technically, and/or typically skylights do not have a fire rating. They are not part of the structural roof therefore do not require a one hour or two hour rating. There are other fire ratings, however. There is Class A or CC1, these are ratings for how much smoke they produce when they are burned, etc. There is also fire-rated glass or glazing.
Some building departments are requesting fire-rated skylights under certain conditions. We have met some of these requirements by supplying a skylight that does not have any aluminum in it’s construction. Call or email (look on this site for contact info) and we’ll get your particular details and a quote.
I have an atrium inside and below the four structural walls. So building department is requiring 2 hour rated glass or translucent cover. Area is 16’x20′. Would you like to supply estimate of glass and frame?
Please email when complete. Thanks.
Matt, Hopefully the information we sent will help with the building department having a more realistic code for the skylights. We are here to help you find a product that will work and feel free to keep us in touch with your progress. Thanks. Rob
I have a 750 SF living room addition to an assisted living/Alzheimer’s facility in Concord, NH. The client has requested a 4′ x 4′ skylight in the roof. As per IBC 2009, the construction type is 5A, which means a 1 hour rated roof. Will I need a rated skylight?
Every jurisdiction determines what will work or not work as far as skylights are concerned. For an accurate answer these type of questions are best for your local building department.
HELP… I need a fixed skylight that meets the requirements for use in Ventura County, CA, high fire zone.
Any advice greatly appreciated!!
Thanks

You can put fire-rated glass in a skylight frame, but the system still would not be fire-rated per se. Occasionally we see local building departments list fire-rated skylights, but there are none. You’ll have to convince them to let you add fire-rated glass to an existing skylight. We can help with that, if needed. Sorry we couldn’t be of more help!
Hello can you send me information about skylight fire rating so I can share with our building inspector and enlighten him. Thank you
does NFPA require the sky light glass for atrium to be fire rated? what skylight glass specification (fire retardant classification) would you recommend?
You would need to check with your local building department for any kind of specification as to what is required. Every jurisdiction has it’s own codes and it depends upon where you live and how strict codes are. Sorry I couldn’t have been more helpful. You could also check with a glass manufacturer that specializes in fire glass production.
