Easy Installation
Seam Mounted Snow Guards are
installed with hex bit sockets and a standard 3/8" drive
ratchet, making installation quick, easy and consistent.
Torque will vary with thickness and metal type Installation is
so easy that they can be readily installed by maintenance
personnel, and can be retrofit on existing structures
when-ever and where-ever sliding snow becomes a problem.
Surface Mounted Snow Guards
are provided with four starter dimples through which self
tapping screws may be driven. It is recommended that holes be
pre-drilled before inserting self tapping screws. Fastener
selection should be governed by substrate and anticipated
loads, but stainless steel or corrosion resistant fasteners
with neoprene washers should be insisted upon. Adhesive or
sealant should be applied so as to completely cover the
underside of the device before it is positioned. Sufficient
compression must be created to squeeze adhesive/sealant out
around its entire perimeter and a bead of the same material
must be applied to create a waterproof joint free of gaps or
air pockets.
Surface Mounted
Snow Guards can be installed using adhesive alone or in
combination with self-tapping screws or other suitable
fasteners.
Adhesive
Where adhesive is to be the sole means of attaching surface
mount snow guards to the roof surface, we recommend the use of
SUREBOND® SB-190 Everseal Sealant Caulk. This is a product
which has a proven record for this particular use and is well
known in the metal roofing industry To assure proper
performance, environmental
conditions as well as preparation
of Snow Guards and the roof surfaces to which they are to be
affixed, should be in strict compliance with sealant
manufacturer's printed recommendations; refer to SUREBOND®
product literature.
To install surface mount snow
guards, contact surfaces shall be wiped with isopropyl alcohol
and adhesive shall be applied so as to completely coat the
underside of the device before positioning it on the roof
surface. After positioning, exert uniform pressure until
adhesive is squeezed out around the entire perimeter of the
Snow Guard and point up joint to create a bead which is free
of gaps or air pockets. It should be noted that under certain
conditions, temporary measures may need to be employed to hold
the Snow Guard in place until initial set of the adhesive has
taken place, and that total cure requires 28 consecutive days
of at least 50 degrees Fahrenheit.
Mechanically Attached Snow
Brakes
Where temperatures will not
be suitable for adhesive installation or where additional
strength is required, surface mount snow guards
may be attached with through fasteners in combination with the
adhesive or with a suitable high-quality silicone sealant
where conditions permit.
