EU Glass is pleased to formally
announce the introduction of 3M VHB
Structural Glazing Tapes G23F
and B23F to the UK market. These tapes are
specifically designed to
withstand the applications
stresses and environmental
conditions faced in demanding
curtain wall glazing
applications.
3M VHB
Structural Glazing Tapes are
available in grey or black with
a film liner. It is precision
slit to meet application
guidelines provided for your
qualified project.
Application Guidelines:
3M VHB Structural
Glazing Tape is a two-sided
pressure sensitive acrylic foam
tape designed to bond glass to
metal frames in glass curtain
wall systems. Each application
will be reviewed on a project
specific basis. Application
guidelines will be based upon
adhesion test results generated
by 3M Technical Service. These
project specific application
guidelines will be provided to
the customer and must be
followed during the glass
bonding process.
Dynamic Loads (deadload
support):
For dynamic tensile or shear
loads (such as windloads), a
design strength of 12 psi (85
kPa) is used for 3M
VHB
Structural Glazing Tape. This
design strength provides a
safety factor of at least five
and was established based on
material property testing as
well as ASTM dynamic load
testing for curtain wall
applications.
Static Loads (no deadload
support):
For static tensile of
shear loads (such as dead weight
loads, snow loads and other long
term loads), a design strength
of 0.25 psi (1.7 kPa) is used
for 3M VHB Structural Glazing
Tape. This means 4 in2
of tape per pound of load should
be used to support static
loads. This guideline provides
a safety factor of at least
five.
Important: Dynamic
and static load calculations
should be performed on
unsupported deadload structural
glazing applications. The
calculations resulting in the
wider tape width should be used
as the appropriate tape width
for the application.
3M VHB Structural
Glazing Tape Warranty:
For qualifying
applications, 3M provides the
curtain wall manufacturer the
confidence that the tape can
deliver high performance and
long-term reliability. Once
your application and assembly
process are approved by a 3M
Technical Service
Representative, 3M guarantees
that the tape will not fail for
the warranty period. See your
3M Representative for details on
obtaining the warranty for your
project.
