How to Choose Window Grids and Mullions for Mandeville, Louisiana Homes

Understanding Window Grids and Mullions

Window grids and mullions do more than divide glass, they frame your view, set the style of your facade, and influence day-to-day maintenance. In Mandeville, Louisiana, the right choice also has to respect Gulf Coast weather, local code expectations, and the realities of heat and humidity.

True divided lites use separate small glass panes set between structural muntins, which are rare on today’s energy-efficient units. Simulated divided lites, or SDLs, put permanent bars on the exterior of the glass, sometimes with a spacer between panes, to mimic the shadow of old joinery.

On impact-resistant units, adhesives and finishes have to be compatible with laminated glass and the manufacturer’s warranty, so do not assume any SDL is fair game. Keep in mind, the grid pattern is cosmetic, while strength and hurricane-rated window installation in Mandeville LA depend on the tested unit and correct fastening.

Matching Grids to Home Style
