Are unairconditioned lanai skylights relevant to a wind mitigation?
Not air conditioned or not enclosed? If its not enclosed then we don’t count it. Enclosed but not conditioned we count it
I have seen the same thing but client had no protection so it did not matter. My question is what about when it fails or gets damaged or blown away busted etc… what about all the damage that will result in the roof, attic system? Never seen that covered in a ny course and it is a Glazed opening that penetrated vital parts of the house. I am not so sure it should not be counted as unprotected if it is not no matter here it goes to.
Not counted for wind mitigation
I always counted them since it would open up the roof to the rest of the house that is over the a/c space; but I’ve never seen it written anywhere.
That’s a good question for the OIR committee :neutral::neutral:
I have seen a few over the years where they mounted panels over the pre 2001 FBC skylights.
Ha ha hhhhhhha hhha hha ha ha like they have ever done a f-cking thing.
Okay, so there is no rule. Great.
I knew that would make you laugh:D
I gave you the correct answer.
John answered the question. Even with a light shaft through the attic space, it still doesn’t count. If it did, we would have to protect vented soffits and gable vents, which are openings to the attic space.
I would think a gable vent on the side of a wall with louvers and a soffit vent underneath a soffit would be a great deal different than a gaping hole in ones roof. Does no one else see that difference. Both other items mentioned are designed to be open and let air flow through a skylight is NOT.
Okay, thanks John. Well, the window company sold them impact grade skylights none-the-less.
That makes sense.
Re-roof permits require impact and new construction requires it also.
Is that state wide? Or depends on you AHJ. The wind mitigation I did yesterday had a brand new roof but the original 1981 skylight.
That’s where it gets tricky. If in a WBDR, it is usually required to upgrade the skylight, however, some areas allow the 25% rule to be used for replacements. In other words, if the permit does not specify, you must verify…
I guess window dealers make their money where they can. I saw a three part sliding door where one panel had broken and they had retrofitted laminated glass into it even though the other two older panels were still single pane. And the gasket/seal looked very rough too.
I had done a WIND MIT about a year ago at the beach; The guy called me recently and said that he had upgraded his windows to impact glass and wanted to document it for his discount.
The glass company switched out the entire house glass in the existing non impact frames with laminated glass. It’s definitely impact glass but not a 2002 and later frame.
Any opinions?
I asked him to have the glass company provide him with a certification just like any other window (FL approval #). I’m not sure what he paid for the retrofit or the sales pitch by the glass company.
The best one yet was the guy that took 2 4x4 post and an old Ford LTD car and wedged it against the garage door for hurricane bracing;)probably works well, but no FL approval #
Love the patchwork of protection people want credit for and the call backs ,updates etc. PIA
Impact rated products have to be approved as an “assembly”. Just replacing the glass is not going to achieve this without a “local product approval” by a licensed structural engineer. Part of any approval is how the frame is attached to the wall.
Very good explanation. Thanks!
It kinda like the “hurricane” window film. The glass will still shear off at the frame. It will just stay in one big sheet when it hits the dining room table:shock:
