Residential insulating glass units consist of two or more panes of glass separated by a hermetically sealed airspace. The use of high-performance insulating glass units in your home can effectively minimize thermal conductivity and prevent unwanted heat loss or heat gain through your windows and doors. Additionally, they can serve as a functional sound barrier without compromising your view of the outdoors. Hartung’s residential insulating glass units can be designed and customized to meet your specific project needs. If your goal is to maximize energy efficiency, we can create a custom unit that features a combination of Argon gas, one or more high performance Low-E coated glass products, and Hartung’s warm edge spacer and premium edge seal technology. If your design intent is to neutralize the effects of intense heat exposure and high-glare conditions, we can produce a unit that features our lower light-transmitting and ultra energy-efficient glass. At Hartung, your goals matter to us. We will partner with you each step of the way to ensure your units are delivered on time and on spec.

Key Product Features

Energy Savings

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

Warm Edge Spacers

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

Noise Reduction

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

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.
