COOLER IN SUMMER, WARMER IN WINTER
TOP RATED ENERGY EFFICIENCY
The National Fenestration Rating Council (NFRC) defines energy performance ratings for the entire
window and door industry. It rates:
• U-factor: How well a window keeps heat inside a building.
• Solar heat gain: A window’s ability to block warming caused by sunlight.
• Visible light transmittance: How much light gets through a product.
• Air leakage: Heat loss and gain by air infiltration through cracks in the window assembly.
Ultrex fiberglass is 500 times less conductive than roll-form aluminum and is similar to wood and PVC.

It provides an insulated barrier against extreme weather temperatures, keeping homes comfortable, and
reducing heating and cooling costs.
ENERGY COST SAVINGS
Marvin was the first major window and door manufacturer to offer energy-efficient Low E2 glass and
ENERGY STAR certified performance on all of our standard windows and doors. Compared to non-
®
certified products, ENERGY STAR certified windows and doors cut heating and cooling costs by 12%.*
The Essential collection offers Low E1, Low E2, Low E3, and Low E3/ERS insulated glass with argon gas,
which has thermal conductivity 30% lower than that of air. It adds improved solar and thermal protection
by distinguishing between visible light, damaging UV, and near-infrared rays to offer the ultimate glass
performance, and provides a selection of energy-efficient solutions depending on your climate and needs.
LOW E GLASS COATING
The Low E coating is specially designed to take advantage of the angle of the winter and summer sun.
Winter sun is absorbed and conducted indoors. Summer sun is filtered and reflected back outdoors.
