Marvin windows and doors are offered in a range of glazing options to meet the performance challenges of any climate. The correct glazing selection can meet code requirements and provide optimal and cost-saving energy-efficiency. Your Marvin dealer can recommend the best choices for your region.
Glazing and Energy Performance
Insulating glass with Low E2 and argon gas come standard with Marvin products. Low E is a general term for low emissivity. Low E coatings are thin metallic layers on a glass surface that manipulate the sun’s light and heat by blocking or reflecting it. Solar heat gain coefficient (SHGC) measures the amount of heat transmitted through a window.
Low E2 is an all-climate glazing featuring two layers of silver on an inside surface of IG glass. It provides year round performance and comfort. In winter it reflects heat back into the room; in summer it blocks heat from the sun.
Low E3 glazing performs well in southern climates where sun exposure is intense and cooling costs are high. Three layers of metallic silver provide the best solar heat gain performance in environments where limited solar heat transmission is preferred.
Low E1 is often selected in northern regions because of its performance characteristics. It blocks heat loss to the exterior and reflects heat back into the room. Low E1 is ideal for building designs that take advantage of the sun’s radiant heat.
Performance Glazing Options
Tripane glazing, available with argon or krypton gas, provides excellent energy performance. Available in products where glazing thickness can be wider than ¾”, it features two coated panes of glass with a third pane sandwiched between them. It's available in a variety of Low E glass options. Tempered and laminated glazing options are available.
