    Sliding door installation

    Sliding door installation

    New postby burtsilver on Tue Jan 27, 2009 5:17 pm

    Codeman,

    Based on the following information, is there a minimum rise at the door track required on single detached construction, grade level, similar to that required when installing the window type in a highrise on the ocean?

    Information:
    Manufacturer: PGT
    Type: Windguard series 630/730
    Opening: 96" X 96"

    Project Location: Palm Beach County off of Lyons Road.

    Hi Burt,

    The information I have, and I found, is for the SGD730. I did not find any for the SGD630.

    There are two heights of sills for those sliding glass doors, one is the Standard sill height which is 2.436 inches high and the High-Rise sill height which is 3.5 inches high. In looking at the Miami-Dade NOA ( http://www.pgtindustries.com/Files/Cert ... issile.pdf ), the High-Rise sill looks like it is a piece which just snaps onto the Standard sill. This is for a two-door track, as your 96" x 96" opening would have (the smaller panels are 4' x 8').

    They have an alternate two-track frame in which the Standard sill height is 2.713" and the High-Rise sill height is 3.5", with this one having a different piece which snaps on to make the sill a Standard sill or a High-Rise sill, but which is not interchangeable with the two-door track referenced above.

    The visual difference between the two types is the first type has an inside sill edge which is basically just a flat vertical piece of metal with another flat vertical piece which snaps onto it for the High-Rise sill, with a thickness of 0.062 inches. The latter of the above two types has a width to the inside vertical edge, the thickness of .494 inches

    With the doors having been tested for air pressure, water pressure and impact resistance, as long as the pressure rating on the door equals or exceeds the design pressure shown on the project drawings there should not be any problems with the Standard sill height. Being 'at grade' reduces the pressure requirements, however, being installed near corners of the building increases pressure requirements.

    Without additional information, such as design pressure to which the sliding glass door pressure ratings could be confirmed to meet, all I can do is go by the general location and the water-tested pressures the doors are tested to, which are: 6.0 psf for the Standard sill and 13.5 psf for the High-Rise sill. The air tested pressures were +/-80 psf for the Standard sill and +/-60 psf for the High-Rise sill.

    Those sliding glass doors were tested to Miami-Dade TAS 201 (Impact Resistance), 202 (Uniform Static Air Pressure), and 203 (Cyclic Wind Pressure Loading).

    Hope that information helps.
