Greater choice of materials and lighter constructions
Flexibility = durability
Thanks to the movement capacity of the TWEHA bonding products, durability is guaranteed.
Rainscreen or ventilated facades are subject to many different forces, be it wind, rain,
extreme temperatures and even earthquakes. The adhesive has the possibility to deform
along with the façade panel. By using screws for example you weaken the connected
material with one or more holes and the shrinkage and expansion of the panels cannot be
absorbed. The façade panel will buckle and in the worst case the panel will break off of the
façade. That will never happen with bonding systems.
Due to the permanent flexibility, it can absorb and endure severe impact, without tearing or
rupturing, giving it the capacity to withstand hurricane-force winds. TWEHA’s bonding
products provide a cushioned foundation to reduce the potential of damages making it an
exceptional choice for many structures within ‘earthquake zones’.
TWEHA’s Bonding Systems remain permanently flexible, without hardening, at extremely low
temperatures; an important consideration when bonding two materials together with different
coefficients of thermal expansion. While they provide a flexible foundation for movement,
even in freezing conditions, other bonding products can become brittle and crack, reducing
the safety factor of the structure. At the other end the TWEHA Bonding Systems are also
resistant to extremely high temperatures and do not break down with exposure to ultra-violet
rays. At elevated temperatures, the tensile strength, elongation and abrasion resistance of
these products is far superior to that of most organic rubbers. In fact after heat aging,
conventional rubber can harden, crack and decompose while TWEHA’s products remain
In other words the outstanding durability, flexibility and movement capacity are fundamental
to the high performance of TWEHA’s Products, making it an exceptional choice for
architects, builders and restoration firms.
