Hartung Glass Industry Blog

Insulating glass units (IGU) used in commercial building applications are generally composed of two or more lites of glass held apart by a spacer material and hermetically sealed around the unit perimeter using a polyisobutylene (PIB) primary seal and a silicone secondary seal. This unit construction is capable of withstanding or absorbing stresses originating from pressure or thermal expansion and provides a stable barrier that works to prevent moisture/condensation from infiltrating the unit and the escape of any specialty gas fill from the unit. 

Laminated glass products are being used in various types of building construction applications serving as durable, translucent fenestration and building interior material options that offer the benefits of daylighting and unobstructed views while also meeting building code standard requirements for safety glazing applications.

Laminated glass is constructed by permanently bonding two or more lites of glass together with a polymeric interlayer sheet using a process that involves exposure to cycles of heat and pressure within a specialized autoclave chamber. The interlayers secure the glass to create a strong, uniformed layer even when broken. Laminated glass comes in a variety of thicknesses and different glass combinations, interlayer components or coatings.

Insulating glass walls are frequently used in commercial building applications. They can provide energy savings, protection against condensation and mold, and even sound attenuation. Hartung Glass Industries has multiple world-class commercial insulating glass facilities across the US and Canada. Each Hartung facility has earned IGCC certification, a standard that verifies that our units are guaranteed to come with lasting durability and a high level of quality.
