Common Window Fastening
Areas such as Florida and the Texas TDI region have different
anchoring requirements based on product certication. For
information on specic products, visit www.oridabuilding.org
or www.tdi.texas.gov and follow the anchoring schedule given in
the drawings for the product instead of the anchoring schedule in
thisdocument.
1. From the exterior, continue to place the fasteners through the
nailing n.
2. Fasteners should be placed 3" – 6" from each end of the nailing n
and no more than 8" on-center.
The use of a drip cap on all window/door products is recommended,
regardless if supplied. A drip cap is required on any vertical mulled/joined
products, regardless if supplied. NOTE: A drip cap may not be suitable
for some product lines (e.g. brickmould vinyl, ush n, vinyl at casing),
regardless these product lines need to be incorporated into the wall in a
weather-shedding manner.
Bracing Installation
1. If the window has a
pre-installed cable
support system,
follow the instructions
provided by the
manufacturer.
2. If the cable support
system is not used,
build a seat board
bracing to support at
least 750 lbs of total
weight (window plus
window contents). Primary support should be provided under the mull
joints of the unit.
3. Remove any temporary support after the full bracing has
been installed.
