Marvin Windows Energy Efficiency Made Easy

Marvin Window Double Hung Exterior Marvin Windows Energy Efficiency Made EasyMarvin Windows will always strive to meet the needs of an ever-changing environment, Marvin builds energy efficiency into product performance while bringing your dreams to life. Marvin windows offers a variety of energy efficient glass options:

LoĒ2-272® – Features a double metallic coating on the inside glass surface to reflect heat into the room in winter and reject the sun’s warmth in summer, reducing damaging UV rays. Offers enhanced U-factor and Solar Heat Gain Coefficient.LoĒ3-366® – Featuring three metallic layers of silver, this glass rejects solar heat and features lower Solar Heat Gain. Recommended for warm climates where cooling costs are high and also for areas where intense exposure to the sun is an issue.

Tripane – Greater energy efficiency is achievable with triple glazing with argon or, for even better insulating value, krypton gas. Tripane glazing is available with Low E coatings to match a variety of climate requirements.

Understanding these common terms will help you select the right windows and doors.

U-factor – This measures the rate of heat loss and how well a product insulates. The lower the number, the better a product is at keeping heat inside a building. The U-factor is key in the winter months, and important to consider in choosing a window.

R-value – This measures resistance to heat loss. Many people are familiar with the R-value because of its use in home insulation. But actually, for windows and doors, U-factor and solar heat gain coefficient are more important measurements.

Solar Heat Gain Coefficient (SHGC) – This measures how well a product blocks heat from the sun. The lower the number, the better. In southern climates or high sun intensity areas, you might actually want to keep the sun’s heat out of your house. Windows can help do that.
