Marvin Windows at Fenway
Harold and Katherine from 360 Chestnut venture to a warehouse next to Fenway Park to learn more about Marvin windows from expert Jim Lockwood.
Marvin windows are highly efficient and have a low U-factor and Solar Heat Gain Coefficient (SHGC). U-factor is a value that determines the rate of heat loss and a small U-factor indicates a high resistance to heat flow and great insulation properties. The SHGC is a number between 0 and 1 that indicates how much solar heat a window transmits. Although a high SHGC can bring additional heat to warm the building in the winter, it can also lead to overheating in the summer and higher energy costs due to air conditioning.
