What Is Window Mulling?

Modern methods in the manufacture of home improvement materials like roofing, siding and replacement windows have come a long way. However, despite the many advances in technology, manufacturing still has its limitations. In window replacements, these are often in the weight of the glass, the structural strength of the frame material and the process of shipping and storage of the final products.

Because of this, replacement windows often have to be built at certain standard sizes. The problem is that sometimes, these standards do not fit the unique requirements of your home. One way to get around this problem is with window mulling. Let our experts at Howard Roofing & Home Improvements explain what window mulling is and what it can do for your own window replacement project.

What Is Mulling?

Simply put, mulling is the process of joining two or more replacement windows together. Your windows and roofing contractor may do this either at your home as the installation is done, or it can be done in the factory as your order for replacement windows are produced. As far as performance ratings are concerned, mulling can be a little bit more complicated than just adding the performance of each individual window.

Do You Need to Mull Your Windows?

Window mulling is a completely optional process. Essentially, you only want it when the current size, shape or construction of your replacement windows are not adequate to achieve the results you want. Mulling can add extra glass areas, giving your interiors better views of the outdoors. With the right glass pane, it can also provide ample daylighting without sacrificing energy efficiency.

What You Need to Know About Mulling

Much like there are small nuances between how two different roofers may install a roof, there are also differences between how contractors mull a window. Some products and installers may include cladding in the process, while others do not. It’s best to talk to your contractor about the process thoroughly so you know exactly what to expect.
