The Shift to Tape-Bonded Facades
Specialist glazing tapes can be used as part of some glass and cladding fabrication systems. Their role depends on the approved system design, substrate, dimensions, environmental exposure, compatible sealants, and the tape manufacturer's technical requirements.
They must not be treated as a universal replacement for mechanical retention or structural sealant. Safety-critical glazing work requires project-specific engineering review and documented compatibility testing.
Why Choose Glazing Tapes Over Liquid Sealants?
Best Practices for Application
A tape bond depends on the complete system. Always follow the current technical data sheet, project specification, and instructions supplied for the exact tape and substrates.
1. Surface Preparation
Surfaces generally need to be clean, dry, stable, and free from dust, oil, oxidation, and release agents. Use only cleaning products and methods approved by the tape and substrate manufacturers; an unsuitable solvent can damage coatings or leave residue.
2. Primer Application
Some coated metals, plastics, and low-surface-energy materials may require an approved primer or may be unsuitable. Confirm compatibility through the manufacturer's guidance and representative testing before production use.
3. Application Pressure
Pressure-sensitive tapes require controlled, even application pressure to develop contact with the substrate. Use the application tool, pressure, temperature range, and dwell time stated in the current product documentation.
4. Spacers and Positioning
Because the tack is immediate, proper alignment is critical. Leave the protective release liner on the tape until the panel is perfectly positioned. Once aligned, pull the liner out from the edge and apply firm pressure.
Final Word
Glazing is a safety-critical application. Obtain written approval from the system designer and relevant manufacturers for load calculations, joint design, substrate compatibility, sealant interaction, environmental exposure, and installation procedure before use.
