Description
Structural Glazing Tape (SGT), is a specialised adhesive system used in the assembly of windows, doors, and skylights, collectively referred to as fenestration units.
Our SGT acts as a high-performance bonding interface system, positioned between the integrated glass unit (IGU) and frame. Particularly within commercial glazing applications such as curtain walls, skylights, and storefronts. It has fast recovery from compression and has been tested to ASTM E96-2005 water vapour transmission to determine open cell airflow structure.
In contrast to conventional sealing techniques that depend primarily on silicone caulking, this tape provides a mechanically robust connection that sustains the IGU’s load while concurrently delivering environmental sealing performance. The tape will give an effective weather proof seal in double sided format. However, some users use a single sided version and apply a silicone seal in addition to give a more durable seal. Please see our Clear Glazing Silicone for more information.
This tape provides a high-strength, resilient bond between IGUs and support frames within fenestration assemblies. Its ability to accommodate differential movement and resist environmental factors makes it a preferred solution for achieving long-term durability and architectural precision in structural glazing systems.
Constructed primarily from acrylic foam, structural glazing tapes exhibit elevated adhesion strength and mechanical flexibility. These properties enable the system to accommodate dynamic stresses such as thermal expansion and contraction, thus preserving seal integrity over long-term service intervals.
Application of Structural Glazing Tape
During installation, the structural glazing tape is precisely applied to the glazing frame to define the bonding surface. The IGU is then accurately aligned and mounted onto the tape, generating a consistent precise space between the glass and the frame. This gap is can subsequently be filled with a secondary silicone—to bolster resistance against air and moisture ingress and enhance overall structural cohesion.
Popular applications for SGT
- Curtain walls and storefront systems
- Glass-to-metal bonding
- Skylights and canopies
- Point-fixed glazing systems
- Unitised façade systems
Performance & Features of Structural Glazing Tape
Our tape offers several performance and features, such as:
Improved Visual Aesthetics: Eliminates the need for visible caulking, resulting in clean and architecturally appealing sightlines.
Accelerated Installation: Allows immediate handling post-application, significantly reducing project timelines associated with curing.
Simplified Fabrication: Streamlines the assembly process relative to traditional wet glazing methods, which require extended cure durations and complex tooling.
Environmental Durability
Engineered for high endurance, structural glazing tapes maintain adhesive and mechanical integrity under prolonged exposure to ultraviolet radiation, temperature cycling, and moisture. These properties ensure consistent performance in demanding climatic conditions without material degradation.

To achieve the best results with tapes or adhesives, we recommend using a primer for adhesives, a UV identifiable primer and our IPA cleaner degreaser with a micro lint free cloth, even when using trial kits. Surface preparation helps to achieve a long lasting, clean bond.
