AfterArchitectural Grilles & SDLs in Columbus, OH
Architectural grilles and simulated divided lites (SDLs) are the grid patterns applied to or built into window sashes that give a home its period character – colonial, craftsman, prairie, or farmhouse. In Columbus, the correct grille profile and configuration can mean the difference between a replacement window that reads as a quality upgrade and one that makes a twenty-year-old house look like a rental. TruePane Windows & Doors has been specifying and installing grille packages on Custom Windows & Doors across central Ohio since 2008, and we know how to match what the house already says without guessing.
If you are already exploring a full custom order, this page sits under our broader Custom Windows & Doors in Columbus service – start there if you want the wider picture of what a fully specified custom window involves. If you landed here specifically because you want the grilles done right, read on. You can also call us directly at (888) 635-0804; a live person picks up around the clock, every day of the week.
What Grilles and SDLs Actually Are
There are three distinct ways a manufacturer builds divided-lite appearance into a window, and the differences matter more than most homeowners are told up front.
True divided lites (TDLs) are individual panes of glass separated by wood or aluminum muntins. They are historically accurate and expensive, and they complicate insulated-glass unit performance because each pane is single-glazed. Most Columbus homeowners living in houses built between 1920 and 1975 – the Clintonville bungalows, the Old Towne East foursquares, the Upper Arlington colonials – have TDLs in their existing windows and want to maintain that look without sacrificing energy performance.
Simulated divided lites (SDLs) solve that problem. The insulated glass unit stays intact and thermally sealed. A grille – usually aluminum or wood – is bonded to the exterior face of the glass, a matching grille is bonded to the interior face, and a spacer bar is sandwiched inside the unit at the same grid intersections. From three feet away, inside or out, the result is nearly indistinguishable from a true divided lite. In the Columbus market, SDLs have become the standard specification for historic district compliance and owner preference alike because they preserve the divided look without compromising the Low-E coating performance that Best Custom Windows & Doors in Columbus, OH must deliver through central Ohio winters.
Interior grilles between the glass (GBG) are the budget tier. A flat grille floats between the two panes of glass with no exterior component and no spacer bars. They look flat and modern – fine for a prairie-style application where that reads as intentional, not ideal for a colonial or craftsman where the shadow line matters.
When You Need Architectural Grilles & SDLs
- You are replacing windows in a home with existing divided-lite windows and the new units look wrong. This is the most common call we get from Bexley and Clintonville homeowners. The replacement windows went in, the neighbors can see the difference, and now the homeowner wants to know what happened. What happened is that the original contractor specified interior GBG grilles instead of SDLs to cut cost, and the shadow line that gave the house its character disappeared.
- You live in a Columbus Historic District or a neighborhood with deed restrictions on window appearance. The Short North, German Village, Olde Towne East, and sections of Clintonville all have design review requirements. SDL configurations with correct muntin width and profile are routinely required for approval. We have worked through Columbus Landmarks Commission reviews before and know what the documentation needs to say.
- You are adding or replacing a window that needs to match surrounding units exactly. A new bathroom window on the side elevation of a 1940s Upper Arlington colonial needs to match the existing double-hung pattern on the front. Grille configuration, muntin width, and profile have to align – otherwise the addition reads as an afterthought.
- You want to change the architectural style of the home’s exterior through window detailing. Some Dublin and New Albany homeowners come to us wanting to shift a builder-grade colonial toward a craftsman or prairie aesthetic. The grille pattern is one of the faster ways to accomplish that change without touching the siding or roofline.
- An existing SDL grille has lifted, cracked, or separated from the glass face. When the adhesive bond between an SDL grille and the glass breaks, the grille can peel or bubble in ways that look like a failed seal. The seal is usually fine; the grille bonding is the issue. This is a repairable problem, and it does not always mean the whole unit needs replacing.
- You are building an addition or a new custom opening and need grilles specified from scratch. Getting the configuration right on paper before the unit is ordered is the only way to avoid a grille package that does not match the rest of the house. We do the measuring, the pattern drawing, and the manufacturer specification before anything is ordered.
Our Architectural Grilles & SDLs Process
- Site measurement and pattern documentation. We measure every opening twice – that is not a slogan, it is standard practice on every job Dale Kessler has run since the beginning. For grille work, we also photograph the existing windows on all elevations, document the current muntin width and profile, and note the sight line of any existing divided lites. In historic Columbus neighborhoods, we check whether a design review submission will be required before we quote anything.
- Grille type and profile selection. We walk the homeowner through the three options – TDL, SDL, and GBG – with clear explanations of what each costs, what each looks like from the curb, and how each performs thermally. For most Columbus replacement projects, SDLs in a colonial, craftsman, or prairie pattern are the right call, and we will say so plainly. We carry SDL specifications from Andersen, Pella, and Marvin among others and can show physical samples of muntin profiles so the homeowner is choosing from something real, not a rendering.
- Side-by-side quotes on paper. If more than one manufacturer line fits the project, we quote them side by side on paper – unit cost, grille cost, lead time, warranty duration – so the homeowner sees exactly what they are buying before signing anything. There are no surprise line items on the bill later.
- Order placement and warranty registration staging. Once the homeowner approves the specification, we place the order and begin staging the warranty registration documentation. Under The Keystone Standard, both manufacturer warranty layers – the glass unit warranty and the product warranty – are registered in writing before the truck leaves the driveway on installation day. Durations are stated. The paperwork is in the homeowner’s hands that same day.
- Installation and pattern alignment verification. On installation day, our uniformed, background-checked technicians set the unit and verify grille alignment on all four sides before the trim goes back up. SDL spacer bars and exterior grille bonds are checked at the perimeter. If the pane is not true, the job is not done – that is the founding rule, and it applies to grille alignment the same way it applies to level and plumb.
- Post-install walkthrough and Done Right Promise. Before we leave, we walk the homeowner through the installation, confirm the grille pattern reads correctly from the curb and from inside the room, and review the warranty documentation together. The Done Right Promise covers the work: if anything is not right, we come back and make it right with no paperwork fight and no fine print argument.
Architectural Grilles & SDLs Pricing in Columbus
Grille pricing in Columbus depends on the type of grille, the muntin profile, the number of lites in the pattern, and the size of the unit. The table below reflects current market ranges for central Ohio. These are not guarantees – glass and aluminum pricing has shifted in the past eighteen months and lead times from manufacturers have varied – but they reflect what we are quoting on real jobs in the Columbus market right now.
| Grille Type | Typical Per-Unit Add-On Cost | Notes |
|---|---|---|
| Interior grilles between glass (GBG) | $40 – $120 per unit | Flat profile, no shadow line, lowest cost option |
| Simulated divided lites (SDL) – standard colonial | $150 – $380 per unit | Exterior grille bonded, interior grille bonded, spacer bar inside unit |
| SDL – craftsman or prairie pattern | $200 – $450 per unit | Wider muntin profiles, fewer lites, more profile material per opening |
| True divided lites (TDL) | $350 – $900+ per unit | Individual panes; historically accurate; higher unit count means higher cost |
| Custom pattern or non-standard configuration | Quoted per project | Prairie geometrics, arched grilles, specialty shapes |
A whole-house grille upgrade on a typical Clintonville bungalow with eight double-hung windows specified for SDL colonial pattern has run between $1,400 and $2,800 in grille add-on cost over the past two years, on top of the base window cost. A single window replacement with a matched SDL package in an Upper Arlington colonial typically runs $220 to $420 for the grille component alone.
What moves the number up: wider aluminum or wood muntin profiles, more individual lites per sash, custom geometric patterns, and historic district specifications that require specific muntin widths for compliance. What moves it down: GBG selection, standard colonial patterns in smaller unit sizes, and ordering multiple units at once.

FAQs – Architectural Grilles & SDLs
What is the difference between an SDL and a GBG grille, and does it really matter for a Columbus home?
An SDL (simulated divided lite) has a grille bonded to the exterior face of the glass, a matching grille on the interior face, and a spacer bar built inside the unit at each intersection. A GBG (grilles between glass) has a single flat grille floating inside the unit with no exterior component. The difference is visible from the curb: an SDL casts a shadow line that reads like a true divided lite; a GBG does not. For a colonial or craftsman in Clintonville, Bexley, or German Village, that shadow line is usually what the house needs to look correct. For a contemporary addition where a flat grid is the right aesthetic, or for Commercial Storefront Glazing applications, GBG may be the better fit. We will tell you plainly which one fits your house and your budget. Call (888) 635-0804 for a free site visit.
Will Columbus historic district design review require a specific grille type or muntin width?
Yes, in most cases. The Columbus Landmarks Commission and neighborhood-specific design review boards – particularly in German Village, Olde Towne East, and sections of the Short North – typically require SDL configurations with muntin widths that match the profile of the original windows. GBG grilles are almost never approved for exterior-facing windows in designated historic districts because they do not replicate the shadow line of original divided lites. We have worked through these submissions before and can document the SDL specification in the format the commission requires, including for projects involving Curtain Wall Systems where grille detailing must integrate with larger glazing assemblies. If you are not sure whether your address falls under design review, call us and we will check before you order anything.
How much does an SDL grille package add to the cost of a replacement window in Columbus?
SDL grilles typically add $150 to $450 per window unit in the Columbus market, depending on the pattern, muntin profile, and manufacturer line. A standard colonial SDL on a double-hung from Andersen or Pella runs on the lower end of that range; a craftsman or prairie pattern with wider muntins runs higher. For a whole-house replacement, grille costs are a line item we quote separately on paper so you can see exactly what you are paying for. Call (888) 635-0804 for a free estimate – no appointment pressure, no obligation.
Can a lifted or peeling SDL grille be repaired, or does the whole window need to be replaced?
In most cases, a lifted SDL grille is a bond failure, not a glass unit failure. The insulated glass unit is usually still sealed and performing correctly. If the adhesive between the exterior grille and the glass face has failed – which happens in Columbus summers when the west-facing elevation gets sustained heat and UV load – the grille can often be rebonded or replaced without pulling the whole unit. We assess the glass seal first; if the unit is still thermally intact, we address the grille bond only. If the seal has also failed (look for fogging or condensation between the panes), then we are talking about a full unit replacement, and we will tell you that clearly up front.
Key Takeaways
