Radius Windows

Mix interesting form with traditional window functionality by adding a radius window to your home. Great for front-facing windows to add charm and style, radius windows enhance home design while letting in natural light.


In an 'arch' or 'radius' window, the bottom half of the window is rectangular while the top is an arch or half-circle. Arch shaped windows bring a softness to a room and juxtaposes the straight corners of rectangular windows and walls for a contrasting effect. Arch windows can be operable to let in fresh air or fixed to only let in light.

A popular way to enhance the design of an arch window is adding grids. Grids are bars that divide the windows glass into smaller panes for aesthetics. Grids are available in exterior and interior options to better simulate real divided lights, while internal grids facilitate glass cleaning.

Rated 5 out of 5 by Best home improvement We ordered Milgard replacement windows and door for two reason quality of product and excellent warranty, the fact that they look pertty does not hurt either. We installed Milgard 10 years ago on a new house and we are so happy with them that when we decided to replace our aluminum windows in our main house we chose Milgard and they are a 100% improvment over what we had. So far so good a year later. June 3, 2015
