Frequently asked questions about standoffs and roof variations
How high above the roof does SunFrame raise the PV
modules?
The answer depends on whether standoffs are used with
the L-feet, and if so, what size. The illustrations at right
provide dimensions for all cases.
How can I seal the roof penetration required when
standoffs are lagged below the roofi ng material?
Many types and brands of fl ashing can be used with Sun-
Frame. However, UniRac designed them for Oatey® 1-1/4˝
to 1-1/2˝ “No-Calk” fl ashing. A wide variety of fl ashings
are described at www.oatey.com. Your choice of sealant
depends on roofi ng material.
How do I attach SunFrame to a standing-seam metal
roof?
A good solution comes from Metal Roof Innovations, Ltd.
(MRI). It manufactures the S-5!™ clamp, designed to attach
a wide variety of products to most standing-seam metal
roofs. It is an elegant solution that eliminates fl ashings
altogether.
SunFrame L-feet will mount to the top of the S-5! clamps
with the 3/8-inch stainless steel bolt provided with the S-5!
