No Need to Stress
Give Some Space
The new JEB 3Seal™ HM+ warm-edge spacer
system for insulating glass units (IGUs) from J.E.
Berkowitz was created to enable bold and ener-
gy-efﬁcient architectural glass solutions.
Designed to meet tough commercial glazing
demands, the spacer
features triple seal technology, including an improved secondary seal made out
of high-modulus silicone, as well as a hot-applied captive polyisobutylene (PIB)
primary seal and a pre-applied acrylic adhesive for spacer to glass bonding.
While traditional metal spacers are highly conductive, the JEB 3Seal HM+ spacer
is made from thermoset structural silicone with integral 3A desiccant, which allows
for minimal thermal conductivity, higher edge-of-glass temperatures, and an im-
proved condensation resistance factor. With its T-shaped design, the product also
offers shock-absorbing properties that counteract glazing stresses caused by wind,
snow, driving rain, ﬂuctuating temperatures and barometric pressure.
Jeffoptics Co. Ltd.’s JF-3E surface
stress meter measures the surface
stress of tempered glass,heat-strength-
ened glass and annealed glass on the
uncoated tin side without causing
damage. The product complies with
ASTM C1279 and ASTM C 1048.
With only two adjustment compo-
nents,operation can be done easily.Re-
sults are available within 0.5 seconds.
An operator no longer needs to judge
the rotation angle or look at the table.
With compact structure and industrial
design,the meter can measure the glass in
The product is available in a range
of proﬁles from 10 mm to applications
exceeding 100 mm. It also allows com-
mercial fenestration systems to meet or
exceed ICC thermal and condensation
resistance factor performance require-
ments, according to the company.
