Structural glazing with tesa tape

Structural Glazing

Great perspectives – our industrial strength double-sided tapes offer high performance in demanding environments. Glass curtain walls are present in commercial buildings all over the world. There are two main bonding methods used for prefabricated building components made out of glass and metal frames, two component bonding with spacer tapes, or one component bonding with acrylic foam mounting tapes (tesa® ACX Plus).

Great perspectives – our double-sided adhesive tapes offer high performance in demanding environments.

There are two types of structural glazing systems: two-sided and four-sided. Each design has its specific advantages.

Two-sided structural glazing systems include a combination of mechanical fixation and a tape bonding system. Two opposite glass edges are bonded to a frame with tesa® ACXplus, and the two other opposite sides are fixed mechanically. With such a system, high mechanical safety can be achieved and two fixation methods (tape and mechanical fastener) help to distribute dynamic forces.

Four-sided structural glazing systems provide an almost frameless appearance. During prefabrication, all four sides of the glass panel are bonded to a frame with tesa® ACXplus in a workshop environment. These glass modules are then attached to the substructure at the construction site and give the facade a look of a flat glass surface. tesa® ACXplus transmits the dynamic loads; however, we do recommend a mechanical dead-load support for the glass that is not visible from the outside. The clear advantage of this system is of course the appearance without a visible frame.

tesa® ACXplus has an outstanding ability to compensate static, dynamic and temperature stress for the complete lifecycle of a component. Due to visco-elastic behaviour, stresses can be dissipated to ensure a secure bond.

Before elements that are assembled with a liquid adhesive can be moved and processed further, the liquid adhesive must achieve a handling strength, which may take from seconds to hours. They cannot be easily dissembled for rework and add to the number of chemicals in a factory. Those chemicals play a role when it comes to maintaining a healthy and clean working environment at a production site.

Both liquids and double-sided tapes require a multistep application process, as contamination of substrates must be avoided. Therefore, cleaning of the substrates is essential for both bonding methods and cannot be avoided. Just like liquids, double-sided tapes compensate for irregular or uneven surfaces. An advantage of double-sided tapes over liquids is the use of thinner product layers which makes the gap between the bonded surfaces as small as possible. With tape, even flexibility in adjusting the materials is possible if the liner is not fully removed. This supports an efficient production process. As no curing time is needed, a faster assembly speed is guaranteed.
