Low-E Options

Clear Annealed / 180 Low-E Annealed - CA1A

Clear Tempered / 180 Low-E Tempered - CT1T

Low-E 180 is designed to perform in northern, heating-dominated climates. This high-performance Low-E glass allows solar heat to pass through, delivering exceptional passive solar gain; a source of “free heat” that naturally warms your home during the coldest months. At the same time, its advanced Low-E coating reflects interior heat back into your living space, significantly reducing winter heat loss and enhancing thermal comfort. Low-E 180 helps maintain consistent indoor temperatures while lowering energy consumption and heating costs.

272 Low-E Annealed / Clear Annealed - 2ACA

272 Low-E Tempered / Clear Low-E Tempered - 2TCT

Low-E 272 is a high-performance Low-E coated glass engineered to deliver exceptional year-round comfort, energy efficiency, and UV protection. Utilizing dual-layer silver technology, Low-E 272 offers a balanced solar control solution ideal for a wide range of climates; from cold northern regions to warmer southern zones. During winter, Low-E 272 reflects indoor heat back into the living space, improving insulation and reducing heating demand. In summer, it blocks a significant portion of the sun’s infrared energy, helping to maintain cooler interior temperatures and ease the load on air conditioning systems.

272 Low-E Annealed / i89 Low-E Annealed - 2A8A

272 Low-E Tempered / i89 Low-E Tempered - 2T8T

Low-E i89 is a cutting-edge interior-surface Low-E coating that enhances thermal insulation and energy efficiency without compromising visibility or clarity. Applied to the room-side surface of an insulating glass unit, Low-E i89 reflects escaping heat back into the interior space, significantly boosting the overall performance of dual-pane windows; approaching the insulating value of triple-pane systems without the added weight or cost.

Pairing Low-E i89 with Low-E 272 is a great solution if you need balanced thermal performance in all seasons, the combination of Low-E 272 on the exterior and Low-E i89 on the interior provides exceptional insulation, solar control, and energy savings.

180 Low-E Annealed / i89 Low-E Annealed - 1A8A

180 Low-E Tempered / i89 Low-E Tempered - 1T8T

Pairing Low-E i89 with Low-E 180 creates an exceptionally energy-efficient dual-pane solution that rivals the performance of triple pane glazing. ENERGY STAR QUALIFIED (SUPERSPACER)
