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. 

When you select high-performance components from Hartung to be used in your IGU assembly, you can further improve building energy performance, reduce peak heating and cooling load costs, increase building appeal and improve the building occupant experience by facilitating optimal daylighting conditions and better sound transmission reduction performance. Some of these customizable IGU components available from your local Hartung partner include laminated glass, high-performance Low-E coatings, Argon gas, warm edge spacer systems, spandrel, and silkscreen - or digitally-printed technologies, tinted glass and textured glass solutions.

 Key Product Features:

**Energy Savings**

Selecting the appropriate energy-efficient glass product(s) and assembly components for use in building openings can help dramatically reduce heating and cooling costs.

**Warm Edge Spacers**

Enhanced edge-sealed, non-metal and hybrid metal spacer technologies enable the lowest thermal conductivity to prevent heat loss, maximize energy savings and optimize building occupant comfort.

**Protection Against Condensation & Mold**

Our insulating glass units offer superior argon gas retention and are designed to significantly reduce condensation and frost to prevent mold and bacterial formation.

**Extreme Climate Solutions**

Hartung has the ability to produce triple-glazed insulating glass units, which are ideal in cold climates where heat retention is critical, and energy code requirements are often much more stringent.

**Sound Attenuation**

For the best sound blocking properties, Hartung’s laminated glass products can be introduced into your unit assembly.

 

Hartung carries an expansive portfolio of commercial insulating glass unit components, including a myriad of glass types and thicknesses from the world’s premier glass manufacturers (Vitro, Guardian Glass, Pilkington, AGC, and Saint Gobain) along with various options for spacer bar materials and finishes. We understand that your business moves fast, and meeting deadlines is essential. We have multiple shifts working around the clock to meet your schedule and your project needs.
