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 Berger Bros Snow Guards can be installed using adhesive alone
or in combination with self-tapping screws or other suitable fasteners.
Where adhesive is to be the sole means of attaching surface mount snow guards
to the roof surface, Berger Bros recommends 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 Berger Bros 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.
Where temperatures will not be suitable for adhesive installation or where
additional strength is required, Berger Bros 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.
