AfterArchitectural Grilles & SDLs in Palm Beach, FL
Architectural grilles and Simulated Divided Lites (SDLs) are permanent or applied grid systems that give modern, high-performance glass the classic, divided-pane aesthetic found in historic Palm Beach architecture. Installing SDLs typically costs between $150 and $450 per window opening, depending on the material, grid pattern, and whether you are retrofitting existing glass or installing new units. If your windows are losing their character or you want to match the historic look of your home while keeping the efficiency of modern impact glass, our Custom Windows & Doors team can help. Call (850) 801-5596 for an accurate estimate on your specific window project.
We see many homes in Palm Beach that were built in the mid-century era, where homeowners want to maintain that traditional colonial or prairie look without sacrificing the safety of modern impact-rated glass. At TruePane Windows & Doors, we specialize in bridging that gap. Whether you are looking for permanent grilles between the glass or exterior SDLs that provide depth and shadow lines, our team ensures the application is precise. This work is a core part of our Custom Windows & Doors in Palm Beach service line, where we treat every opening as a piece of the home’s total structure, not just a hardware replacement.
Founded by second-generation glazier Dale Kessler in 2008, we have spent years understanding the unique climate demands of Florida. We know that salt air can degrade cheap adhesive grids, and the intense sun can warp inferior plastic inserts. That is why we focus on durable, manufacturer-approved solutions from lines like ES Windows and ECO Window Systems. We stand behind our installations with the Done Right Promise and The Keystone Standard, ensuring both manufacturer warranty layers are registered in your name before our truck leaves your driveway.
When You Need Architectural Grilles & SDLs
Not every window needs a grid, but when the architectural integrity of your home depends on it, the quality of the install matters. For properties requiring Commercial Storefront Glazing, precision is especially critical. We frequently assist Palm Beach homeowners who are facing specific scenarios where standard, plain glass just does not fit the house.
- Restoring Historic Charm: If you have replaced original wood-sash windows with modern impact units, the new glass often looks too “flat.” We install SDLs to restore the shadow lines and depth that define the historic aesthetic of your neighborhood.
- Matching Existing Patterns: When one or two windows in a room are damaged and replaced, they often lack the grids present on the surrounding windows. We custom-match the grid pattern and color so the new units disappear into the existing design.
- Updating Curb Appeal: A simple, plain-glass sliding door or large picture window can look stark against a traditional stucco or coral-stone exterior. Adding a perimeter or colonial grille pattern can anchor the window to the home’s design.
- Preventing Bird Strikes: Large, clear picture windows in areas with heavy landscaping can be dangerous for local birds. Applying a subtle grid pattern can break up the reflection, making the glass more visible without obstructing your view of the Intracoastal or your garden.
- Correcting Poorly Applied Grids: We often see DIY or inferior contractor-applied grids that are peeling, yellowing, or crooked. We can remove these failing components and install professional-grade SDLs that are designed to withstand the humidity and heat of Palm Beach.
If you are unsure whether your current window configuration can accept SDLs, give us a call at (850) 801-5596. We can perform a site visit, check the manufacturer specs of your existing units, and let you know exactly what is possible. Our technicians are background-checked and uniformed, and they measure every opening twice to ensure the grid alignment is perfect.
Our Architectural Grilles & SDLs Process
We do not use shortcuts. When we install grilles or SDLs, we follow a specific sequence designed to ensure the bond is permanent and the alignment is square. If the pane is not true, the job is not done. This is how we approach every project:
- Initial Assessment: We first determine the type of glass you have. If you have impact-resistant glass, we must ensure any adhesive or mechanical fastening does not compromise the integrity of the interlayer. We look for manufacturer-specific requirements from brands like CWS or ViewLux.
- Precision Measurement: Every window is unique, even in the same house. We measure the sightlines and exact glass dimensions to ensure the grille pattern is perfectly centered and symmetrical. We do not guess; we measure twice.
- Surface Preparation: This is the most critical step. We clean the glass surface with specialized solvents to remove all traces of salt, oils, and silicone residue. If the glass is not surgically clean, the adhesive bond will fail in the Florida humidity.
- Application and Bonding: We apply the SDL bars using high-performance, UV-resistant structural tape designed for the exterior environment. We use spacers to ensure consistent spacing between the grids, creating the look of true divided lites.
- Final Quality Check: We inspect the alignment from both the interior and exterior to ensure the grids look straight and uniform. We then clean the glass thoroughly, leaving your windows clear and the new grilles secure.
- Warranty Registration: Before we leave, we register both the manufacturer’s warranty and our own workmanship guarantee. You receive the paperwork in writing, fulfilling The Keystone Standard.
We treat your home the way we would treat our own mothers’ homes. When we finish, we clean up our workspace completely, leaving nothing behind but a job that is done right.

FAQs - Architectural Grilles & SDLs
Can you match the grid pattern on my existing windows?
Yes, we can match almost any existing grid pattern, including custom colonial, prairie, diamond, or Custom Shape Windows configurations. During our initial visit, we take detailed measurements and photos of your current windows to ensure the new SDLs align perfectly with your home’s existing aesthetic. Call (850) 801-5596 to schedule a time for us to look at your windows.
Do SDLs affect the energy efficiency of my windows?
SDLs are applied to the surface of the glass and generally do not impact the thermal performance or energy efficiency of your windows. Because we use high-quality materials from manufacturers like CWS and ES Windows, the bond remains stable even with the thermal expansion and contraction cycles typical of the Palm Beach climate. If you are concerned about heat gain, we can discuss the specific UV-blocking properties of the materials we use.
How long does the adhesive last in the Florida heat?
The adhesives we use are specifically rated for outdoor exposure and high-heat environments. When applied to a properly cleaned and prepped surface, these bonds are designed to last for many years without peeling or yellowing. If you ever have an issue with a grille coming loose, our Done Right Promise ensures we will return to fix it, no questions asked.
Is it better to replace the whole window or add SDLs?
If your windows are structurally sound, energy-efficient, and in good condition, adding SDLs is a cost-effective way to update your home’s look without the expense of full replacement. However, if your windows have fogged seals, binding sashes, or failing locking mechanisms, we would recommend a full home window assessment. We are happy to provide an honest opinion on whether your current windows are worth the investment of adding grids or if they are nearing the end of their service life.
