About the Harvey Classic Double Hung 3-Wide Mulled Unit

A mulled window unit is when two or more windows are joined together to form a single unit. Mulled window units offer an aesthetically pleasing exterior and more expansive views from the inside.

This mulled unit includes three Harvey Classic double hung windows (pictured above) or one picture window flanked by two double hung windows.

These custom-made Harvey Classic vinyl double hung windows come in many styles, hardware options, and colors.

Solar heat gain coefficient measures how well a product blocks heat caused by sunlight.

The lower the number, the more it will help reduce the use of air conditioning and energy use. In cold climates, a higher SHGC is desirable to collect heat from sunlight. SHGC typically ranges from 0.25 to 0.80.
