Drawbacks of Arched Windows

No Ventilation

Arched windows are ideal for letting in light, but not so much for allowing airflow. If you are looking for something with more ventilation, try combining an arched window with a double hung or casement window.

Cannot Be Used as an Escape Route

Because the window is fixed in place and does not open this is not an ideal design for use as an escape route during a fire or other emergency.

Cost of Ownership

Arched windows have no moving parts such as hinges or latches, but there is a high cost of ownership both in installation and maintenance cost.

Window Size and Shape

The size and shape of window is normally predefined based on the construction of your home. Modifying a brick or structural component of your home is often labor intensive and costly.

Types of Arched Windows

There are many types and variations of arched windows available today. Some of the most common designs are fixed shut and other incorporate windows such as double hung and casements to create a specific pattern and enable air flow. The most common types of arched replacement windows are:

Fixed Arch Windows

This accounts for most of the windows on the market. Fixed arch windows provide excellent aesthetics because they allow in a huge amount of natural light. Since these do not open, they are very weatherproof, good for energy efficiency, but do not provide an escape route. They work best when paired with other styles of windows.

Opening Arched Windows

If you are looking for the classic arch window with a bit of airflow, consider pairing with a double hung or casement window for optimal airflow.

Extended Leg Half Round (Eyebrow Arched Windows)

Arched windows which are made from several different windows combined and aligned into an arch configuration are commonly called eyebrow arch windows. They are made of rectangular windows which can open and close, and a semicircle or geometric window on the top to provide the arched look. These offer the same architectural look and added airflow.

True Arched Windows (Geometrics and Specialty Shape)

Geometrics and specialty shaped windows, such as a half rounds, are more commonly known as an arched window. A true arched window will have proportions where the maximum height of the window is ½ the total width of the window, and arcs evenly over the entire width.

Arched Windows (FAQ) - Frequently Asked Questions

Here are some of the most frequently asked questions (arched windows FAQ) we've answered dover the years about replacing and installing windows.

An arched window (commonly called an eyebrow arch, extended leg half round, or radius window) is commonly made of a square window with a curved top window. These bring a level of softness and sophistication to any room. Fixed arch windows do not open, but when made of a square window and a radius top window, they do.

Arched window installation cost can be higher than traditional double hung or casement windows because they usually come as a custom order. Arched windows ordered as a single fixed pieces require specialized installation to ensure a proper fit. Arched windows created from a rectangular window with a curved or radial top are often more affordable and have better ventilation.

Arched windows are excellent design pieces and when paired with other windows provide a spectacular exterior home appearance. They like in a huge amount of natural light and always make larger rooms pop.

Arched windows are commonly preferred on larger homes for the following reasons:

  • Dramatize the height and depth of a home – making it appear larger and let in more light.
  • Round off corners or entry ways – These make great first impressions on the front of your house or near doorways.
  • Extends front entry ways, stairwells, and patios – Arched windows can emphasize the height of rooms and enlarge the openings of walls.
  • Custom appearance – These can be made with unique color attributes or styling patterns from inserts.
  • Soften architectural accents – Arched windows are commonly used in modern home design to de-emphasize the harsh roof lines and to highlight the home and room height.

The cost to install new arched windows depends on the desired style. Typically, a fixed arched window, which does not open, is on the more expensive end and can cost around $500 - $900. Whereas an arched window consisting of double hung plus a radial top will be on the lower end of that scale.
