Tips

Best windows for natural light

With the many benefits of natural light, replacing your windows offers a great opportunity to think differently about window styles to increase your home’s natural light.

Double hung and single hung windows 

Double-hung and single-hung windows make great candidates for replacement options because of their tall profile and ability to be arranged in an assembly of multiple windows or as part of a bay window. Infinity's Double and Single-Hung Windows are built with the strength Ultrex® fiberglass, so you’ll enjoy slimmer window frames for bigger views. You'll also want to consider the visible transmittance (VT) of the windows. VT measures the amount of visible light that passes through a window. A higher VT number means more light passes through to better illuminate a room.

Casement windows

Casement windows have one sash for an uninterrupted view.

Bay windows

Infinity Bay Windows provide ample natural light with either casement or double hung windows arranged in 30° or 45° configurations. Opt for an operating center window to increase airflow into your home, too. Enjoy abundant natural light in your new cozy reading nook with insulated head and seat boards.  

Bow windows

Bow windows use a combination of four, five, or six casement windows to allow more natural light into your home. The flanking casement windows can open to capture a refreshing breeze. 

Only the casement windows at each end of the bow window are operable.  

Arch and round top windows

Infinity Arch and Round Top Windows can utilize untapped space to increase natural light. Round top and arch windows can rest above windows and add curved lines to your home’s architecture. Round top windows include full circle windows, which can add light in homes with vaulted ceilings.  

Special shape windows 

Special shape windows can do special things for homes by creating more opportunities for natural light. Special shape windows have strong geometric lines and can come in trapezoid, pentagon, triangle, octagon, rectangle, and hexagon form. Special shape windows have versatility because they don’t have to fit directly above a window.

Best window placement ideas for natural light

You can amplify natural light by carefully choosing the right types of windows for different parts of your home. You want to pay particular attention to the direction a room faces. The amount of daylight a south-facing room brings differs than a north-facing room. A room that faces the west encounters more sunlight in the afternoon than one that points to the east.

  • South-facing windows: South-facing windows experience the most sunlight in the northern hemisphere. Large living room windows that face south can maximize natural light, which brings the benefit of not needing as much artificial light to illuminate the space.

  • East and west windows: East-facing windows capture sunrises, which makes them great for bedrooms or morning dining spaces. West-facing windows face a setting sun and can bring increased solar heat. In rooms that face the west, window treatments can help with solar heat. West windows aren’t as ideal in spaces like a kitchen if you cook often.

  • North-facing windows: Windows that face the north receive the least amount of sunlight. They do provide softer light since it’s not direct like rooms that face the south or west. North-facing windows suit home offices and bathrooms.
