When it comes to grille design, sky’s the limit for Renewal by Andersen® of Milwaukee.

Classic Window Grille

Ingenuity may be in our DNA, but we specialize in these standard patterns:


This pattern represents the affinity for symmetry of traditional architectures, including the Georgian, the Federal, and the Cape Cod. It’s easily recognizable with its crisscross muntins, which are generally featured in every double hung window in the house.

In the past, a 12-over-12 pattern of divided lights is popular due to the unavailability of large glass. Now, a six-over-six pattern is common among modern interpretations.


Unlike the colonial, the prairie grille leaves the center of the glass plain and unbroken. Instead, it lines all four sides of the window, creating a perfect square in every corner.

This grille option is almost exclusively used in its mother architecture and namesake, which is big on the casement. However, eclectic homes borrow it for decorating double hung units, featuring the pattern in each sash. Because some homeowners like a simpler look, the modified prairie was born. This iteration gets rid of the extra lines and treats upper and bottom sashes as a single panel when applying the grilles.


The farmhouse grille design is perhaps the simplest. Its popular version creates a realistic replication of four-pane window when closed. Its other variety, though, lends more interest to double hung, casement, and even picture windows.

It comprises two vertical bars that meet a wider horizontal rail at the center of the unit. When not used in a sash window, it creates an impression of a double hung with a three-pane upper panel and a plain bottom.

Simulated Double Hung

If you love the benefits of crank replacement windows but want them to look like their sash counterparts, we can trick the eye with grilles. The simulated double hung grille pattern can disguise casement units as double hungs. This way, you can increase your home’s energy efficiency and meet local fire egress codes without affecting curb appeal.

Apart from specializing in a variety of patterns, Renewal by Andersen of Milwaukee also is adept at an array of grille configurations. To learn more about our window and door customization options in Waukesha, call us now at (877) 977-3639 for your free, in-home consultation.

Hear From Our Customers

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
