Dallas, Tarrant, Collin and Denton Counties
Sliding and folding glass doors in Dallas–Fort Worth.
DFW is where we do the most new build. Large flat sites, architect-drawn rear elevations, and clients who have already decided they want the glass — the conversation here is usually about span and structure rather than whether to do it at all.
Working in Dallas–Fort Worth
What the work looks like here.
The metroplex builds big and builds new. On a typical Preston Hollow or Southlake project we are working from drawings months before the opening exists, coordinating with the structural engineer on head deflection and with the builder on the sequence — because a forty-foot sliding run imposes real constraints on the frame above it, and those get much more expensive to solve after the steel is up.
The engineering question that comes up on nearly every DFW job is deflection. A wide opening spanned by a beam that moves under load will bind a sliding door, and no amount of adjustment on site fixes it. We give the engineer our maximum permissible head deflection in writing at design stage, and we would rather have that argument early than hand over a door that drags in year two.
North Texas also swings harder through the year than the rest of the state — genuinely cold snaps against long triple-digit summers. Thermally broken frames matter more here than people expect, and so does the quality of the seal, because the same assembly has to stay tight across a much wider temperature range than a Gulf coast equivalent.
What actually drives the spec here
You can build bigger here than in Houston.
Dallas and Fort Worth design to roughly 105 mph, against about 136 mph on the Gulf coast. That gap is the single most useful fact about glazing in North Texas: the same system carries more glass over a wider span here, because the wind load it has to resist is far lower. What did change is the energy code — Dallas and Tarrant Counties moved from Climate Zone 3A to 2A in the 2021 IECC, so DFW now works to the same fenestration numbers as Houston rather than the milder ones it used to.
| Climate zone | 2A — moved from 3A in the 2021 IECC |
|---|---|
| Max U-factor | 0.40 |
| Max SHGC | 0.25 |
| Design wind speed | ~105 mph (ASCE 7-16, Risk Cat. II) |
| Windborne debris region | No |
| TDI windstorm certification | Not required |
Checked against the adopted local code, August 2026. Codes change and requirements can be address-specific — we confirm yours at survey before anything is ordered.
Systems
Two systems, both installed by us.
We make sliding and folding systems and nothing else. Which one suits your opening depends on whether you want to frame a view or clear the whole wall.

Questions
Glass doors in Dallas–Fort Worth, answered.
The things people ask before they book. Still unsure? Send the opening and we will give you a straight answer.
Do you work from architects' drawings on new build?
Yes, and we prefer to be involved early. We issue our head-deflection limit and structural opening requirements at design stage so the engineer can size the beam for it. Bringing us in after the frame is up narrows the options and usually costs more.
How wide can you span in a single opening?
A single sliding run can reach roughly 43 feet across up to six panels, and it can turn a 90° corner without a structural mullion. The practical limit on a given job is almost always the structure above the opening, not the door system.
Does hail affect what glass you would specify in DFW?
Less than people expect, and it is worth being straight about why. Texas is the worst hail state in the country, but the impact-resistance rules and the insurance discounts that go with them apply to roof coverings, not glazing — no adopted Texas code contains a hail requirement for glass. Anyone telling you that hail obliges you to buy a particular glass make-up is selling rather than specifying. Glazing here is governed by wind load, dead load and safety-glazing rules, and we specify to those.
Did the energy code for DFW change recently?
Yes, and it caught a lot of people out. Dallas and Tarrant Counties moved from Climate Zone 3A to 2A in the 2021 IECC, which Dallas adopted in May 2023. The practical effect is a maximum U-factor of 0.40 and a maximum SHGC of 0.25 on vertical glazing — the SHGC is the number that decides the glass make-up on a large sliding wall.
Do you cover both Dallas and Fort Worth?
Yes, and the surrounding counties — Dallas, Tarrant, Collin and Denton. The same team surveys, fabricates and installs, so coverage does not change who turns up.
