The Benefits of Basement Egress Windows

There are so many benefits to basement egress windows! These include:

  • Provides a safe escape both in and out of your house in case of an emergency
  • Increases the amount of sunlight that enters your house
  • Increases your home’s value
  • Add additional safe living space to your home
  • Increases airflow in stagnant basements
Provides a Safe Escape

Egress means “to emerge” or “a path out”. True to their name, egress windows are openings specifically designed to create a safe escape from an emergency. These egress window openings also make it easy for police and firefighters to get in to help you. Your local and national building codes will define the specific minimum requirements for these windows to ensure that you can get out. Hopefully you never have to deal with an emergency situation in the lower level of your home, but if you do having that Egress Window installed by Reliable Basement could save lives. Municipalities all have different rules for when they are required, but they are always required in basement sleeping quarters.

Doubles the Safe, Usable Size of Your Home

Remodeling your basement might be your most affordable option to increase your living space. In the majority of homes a basement can account for 1/3 to 1/2 of the total square footage. Many unfinished basements just become a giant storage room instead of usable space. If you intend to finish your basement and spend quality time down there you should really consider installing an Egress Window.  Reliable Basement Services can install basement egress windows and window wells  that will blend in with the exterior of your home and complement your interior décor. Some windows come with additional features such as terraced steps molded into the wells, which make for an easier escape than the alternative of a traditional ladder.

Increases Home Value

If you want to finish your basement or are even considering a basement renovation, you should research if there is a town requirement for basement egress windows. In most towns, this is a requirement. This requirement is tied into rules related to Real Estate transactions. Square footages of basements may not count when calculating a homes value if all the requirements are not met Most building codes also mandate the installation of basement egress windows to provide an adequate escape route in case of an emergency. Not only does an egress window increase your home’s safety, but it also increases your home’s value, your home’s airflow, and the natural lighting in your basement. An egress window can make even the darkest, stuffiest, most unpleasant basement spaces into a welcoming environment.

Increases Sunlight

By installing basement windows, your basement will dramatically increase in brightness. You won’t have a dark, dingy basement that no one wants to be in anymore. Our standard and most popular window is the 48″ X 48″ sliding window. It completely changes how a basement room feels.  Whenever you want to remodel your basement to make a new bedroom, office, or other living space, you should always have egress basement windows installed.

Egress Window Size Requirements

The International Residential Code (IRC) sets the requirements for egress windows. They may be slightly different in local building codes, so make sure you check that you are compliant with the local requirements in your area.

An egress window must meet four IRC criteria:

  • The width of the opening must be at least 20 inches
  • The height of the opening must be at least 24 inches
  • The net clear opening must be at least 5.7 square feet
  • The sill height above the floor must be at least 44 inches

An egress window well must meet two IRC criteria:

  • The well must have a foot print of at least 9 square feet
  • The well must have a projection of 36″ off the house

The net clear opening refers to the actual free and clear space that exists when the window is open.

This is not the rough opening size or the glass panel size, but the actual opening that a person can crawl through. Your window must be able to open easily from the inside without keys or tools. You may install bars, grilles, and grates over the window, but you still must be able to open the window to the minimum clear opening without tools or keys. You might make the mistake of assuming a window that measures 20 inches by 24 inches would be a big enough egress. However, those dimensions will not yield a net clear opening of 5.7 square feet. Instead, it will only be about 3.3 square feet. You will need either a 20-inch by 42-inch window or a 24-inch by 34-inch window to make it the appropriate size. Basement egress windows are not just a top safety feature but also a great investment. They require careful planning, selection, and installation for any living space or remodeling project. You must make sure that your window meets both Section 310 of UBC and IRC 2003 Building Code.

Types of Egress Windows

Slider Egress Window

These windows slide open and closed and are mounted upon tracks and runners. Some styles open vertically while others open horizontally. Size requirements can be a bit more of a challenge with slider style basement egress windows. We install a 48-inch by 48-inch window to make sure you have the appropriate size. The net clear opening as discussed above is 4 feet by 2 feet minus the framing so this style of window is well above the 5.7 Sf that is required by most building codes.

Casement Egress Window

Casement windows are a great choice for basement egress windows. They often have large panes with hinges along the side. These hinges allow the window to be completely opened by swinging inward or outward. This makes them especially easy to crawl through in an emergency situation. They are perfect for bedrooms and basements because they occupy such little wall space but offer the greatest, easiest escape route.
