Insulated Glass
Manko specializes in high-quality insulated glass units (IGUs) tailored to your project’s environment. Manko has invested in state-of-the-art glass insulating equipment which apply warm edge technology spacers via automated robotic machinery, ensuring quality, consistency and longevity. For additional thermal performance, these IGU lines use a specialized chamber-fill process providing reliable argon gas insulation to help meet the strictest energy specifications. Whether your project requires standard dual-pane, high-performance triple-pane, or secure laminated options, Manko can manufacture IGUs from 1/2" to 2" thick.
Low-emissivity (low-e) coated glass may have various combinations of metal, metal oxide, and metal nitride layers of coatings that are nearly invisible to the eye. Whether driven by building codes, appearance, or by specifications, there is a proper low-e coating for your project. Different coatings on the same glass substrate can alter visible light transmittance and provide different levels of solar control. There are several benefits of low-e coated glass, some of the major benefits are aesthetic appeal, energy savings, and occupant comfort. Depending on your specific climate the low-e can either absorb heat conducted indoors, or absorb heat reflected to the outdoors.

Manko fabricates architectural glass from Guardian Glass, Vitro Architectural Glass, Cardinal Glass, and Pilkington Glass.
Manko creates highly efficient IGUs by using warm-edge technology spacer capabilities on each insulated glass line through advanced automation. By producing a unit with a warm-edge spacer, our customers are receiving a high-quality IGU with enhanced thermal performance, reduced sealant stress, increased sound absorption, and improved condensation resistance. If your project requires an alternative to our standard warm-edge spacer offerings, Manko carries supplementary traditional spacer options.
Added Benefits & Features of Warm Edge Spacers:
- Contributes to LEED Certified Projects
- Reduces Energy Consumption
- Reduces Seal Failure
- Passes Toughest Industry Test (ASTM E2190)
- Provides Warmer Sightline
- Improves System U-Value
- Reduces Noise Pollution
Specifying a glass type that meets your projects needs must take into consideration natural daylight, solar heat gain (infrared radiation), and damaging ultraviolet (UV) rays. The glass should act as a filter for the sun’s energy using the low-e coating, allowing the visible light to pass through. Often measured by Light-to-Solar Gain (LSG) Ratio, VLT / SHGC. The threshold for a “spectrally selective” glass type is 1.25 or higher.
Visible distortion of glass is not limited to only the heat-treatment process, but also the insulation process into a dual or triple pane unit. As the barometric pressure falls or rises, the unit likewise expands or contracts. This causes the two lites of glass to bow away from or toward each other, and because of this, objects viewed in reflection will be distorted. When designing it is also recommended to try avoid 1:1 aspect ratios, as increased distortion will likely be apparent.
Transportation of insulated glass units through, or delivery to, high elevations may require a breather tube to allow the unit to adjust to extreme changes in pressure. Manko utilizes capillary tubes as they are longer and have a smaller inside diameter compared to traditional breather tubes. It is recommended to allow the IGU to acclimate to its final destination for a minimum 48 hours to allow for effective pressure equalization, then sealing the tube per manufacturer’s instructions.
Project specification documents should require that compatibility of all glazing sealants and other components be confirmed with the sealant manufacturers and the insulating glass fabricators. It is important to confirm whether the specific framing system being used can accommodate the required specific overall thickness of an insulated glass unit, i.e. IGUs using thicker laminated glass products.
Manko provides a 10-year limited warranty, up to 50 sq. ft., on all IG’s (with any of our spacers) produced unless otherwise specified. Even though Manko can produce units up to 60 sq. ft., Manko will warranty units up to 50 sq. ft., below are the maximum dimensions the IG lines can produce:
Manhattan – 142” W x 96” H
Denver – 142” W x 96” H
Des Moines – 142” W x 94” H
Manko’s insulated units are compliant with the following codes:
ASTM E2188 – Standard Test Method for Insulating Glass Unit Performance
ASTM E2189 – Standard Test Method for Testing Resistance to Fogging in Insulating Glass Units
ASTM E2190 – Standard Specification for Insulating Glass Unit Performance and Evaluation
