About the Harvey Classic Double Hung Mulled Window 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 two Harvey Classic double hung windows (pictured). Double hung windows are more versatile and easier to clean than their single hung predecessors since both panes open and tilt in.

The Harvey Classic vinyl double hung window is custom made, delivers excellent performance, and offers a variety of styles, colors and options to meet your needs.

As one of a very select group of Harvey Elite Dealers, we are able to provide enhanced benefits including free lifetime glass breakage coverage, a more affordable triple pane option, and an upgraded service warranty option.


This mulled unit includes two Harvey Classic double hung windows that are joined together as one unit (pictured). The Harvey Classic vinyl double hung window's sleek fully welded sash and frame design provides a one-piece sloped sill with an air-tight seal keeping water and wind outside. We automatically include the ENERGY STAR® qualified glazing upgrade with Dual Low-E coating and Argon gas. Other features include:

  • Multi chambered extrusion enhances structural and thermal performance
  • Factory calibrated block & tackle sash balances, which never need adjustment or lubrication
  • Includes locking fiberglass half screen

U-factor indicates how well a product prevents heat from escaping.

The lower the number, the better. To meet Energy Star requirements, windows must have a u-factor at or below 0.27.

U factor


Thermal performance is a rating on a scale of 4 of the overall energy performance of the product.

Thermal Performance


Visible transmittance refers to how much visible light comes through the product.

The higher the number, the more light is transmitted. VT values typically range from 0.30 to 0.70.

Visible Transmittance


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.
