How To Install Two Outside Windows Simultaneously?

This video demonstrates how to connect two windows together using a mull, a simple process that saves time and effort. Mulled windows are two or more separate windows joined together to fit into a single wall opening, making them a more efficient way to install windows. To install mulled windows, snap mullions (or H mullions) must be permanently attached during installation.

To install the mulled windows, attach an 8 x 2″ Phillips installation screw in 3-4 staggered locations from inside the home. Mulled windows can give a house a new and improved look, as they are two smaller windows in one. To trim the windows separately, add an additional 2×4 between each window to prevent overlap.

Clad wood windows can be joined on-site with screws and optional trim pieces, and mulls are anchored to the opening frame. Windows can be placed together in multiple units into any opening, and the same installation can be done with a double trimmer stud between them. Trim can be used to cover the gap, or a single stud can be used if space is tight.

Mulling is a process that involves joining two or more windows together by their frames, and it can be done at a factory or on-site during new home construction, remodel, or window replacement. Windows By Toll is a local source of mulled replacement windows.
