Egress-Compliant Basement Windows

Energy-efficient, customizable, maintenance-free

Window Well Experts offers basement windows suitable for new construction or replacements. The products are rated by Energy Star.

The patented design of our egress installations allows the header, sill, and jamb pieces to be removed, reversed, and replaced to easily adapt the installation to any situation. In addition, sashes are easily removable when not locked, allowing a wide, clear opening to move material through during construction.

Also, they do not subtract from the egress well square footage and compromise your ability to comply with local codes.

What is an Egress Compliant Basement Window?

An egress window is intended to provide an emergency escape or rescue opening. Those are especially required if the basement is used for living space – bedroom, office, playroom, etc.

Select the Best Basement Window Type to Match Your Well Cover

If you are interested in renovating a basement, you must consider the windows’ impact on the room’s entire appearance. Moreover, old basement windows can cause a variety of inconveniences and problems to any homeowner:

  1. Difficult to manage. Usually, the frames of the old windows are covered with rust or rotted, making them extremely difficult to open.
  2. Poor energy performance. The standard old windows are single-pane, allowing cold air in the underground space. Replacement basement window inserts can improve the home’s insulation and bring energy bills down. 
  3. Basement filling with water. One of the most common problems caused by single-pane glass basement windows is that they cannot hold the water, which causes leaks between the frame and the rough opening.
