Glass protection and cleaning

Since it is difficult to protect glass from damage during construction, it is important to check daily and document glazing materials if building teams need to provide evidence of post-glazing damage. In addition, a number of best practices should be followed to best protect the glazing on the jobsite.

  • Paint, plaster, and sealant spills or splashes should be removed from the glass immediately.
  • Protection should be provided to prevent weld splatter, sand blasting, concrete alkaline deposits, or other caustic materials from contacting glass surfaces as these materials will permanently damage glass surfaces.
  • Protective coatings or release agents applied to the glass should be evaluated for compatibility to the IGU, the glazing system, and the fenestration system’s frame. Compatibility should be specified as part of the project.
  • Glass surfaces should be cleaned soon after installation and on a regular basis if surrounding construction leaves deposits such as concrete runoff, rust stains, sealant bleeding, etc., on the glass.

Knowing IGU glazing guidelines

IGUs can be a performance asset to a commercial project. Specifiers can refer to guidelines such as those found in IGMA TM-3000 to ensure they are making informed decisions when it comes to specifying IGUs.
