Mirador 111S vs 111DA: Which Manual Louvered Pergola Fits Better?

The core difference: construction and evidence

Mirador positions both 111S and 111DA as manual louvered pergolas, but the construction we currently track is different. The 111DA exact product pages list an aluminum frame with aluminum louvers. The 111S exact pages list an aluminum + alloy-steel frame with galvanized-steel louvers.

That material difference is paired with different published weather figures in the current evidence. The 111DA exact 10x10 and 10x13 pages we track publish 102 mph wind and 26.6 psf snow claims with professional assembly and anchoring conditions. The 111S exact pages publish 90.2 mph wind and 20.8 psf snow figures, with the 10x13 page explicitly tying them to professional assembly and anchoring.

111DA: stronger published structural figures

For buyers prioritizing the strongest current Mirador figures in this manual size class, 111DA is the clearer fit. Its 102 mph wind claim is 11.8 mph above the 111S figure we track, and its 26.6 psf snow figure is 5.8 psf higher.

Those differences are useful for comparison but they are not a site-approval decision. Exact anchoring, foundation, local design loads, roof position and any permit or engineering requirements can still be more restrictive than a manufacturer headline.

111S: value-oriented manual louver control

The 111S keeps the same basic buying proposition of manual adjustable louvers and integrated drainage while using a hybrid material construction. Mirador's current exact product data lists a 93° louver opening for 111S versus 98° for 111DA.

For a buyer who does not need the higher published 111DA weather figures, 111S can be the simpler value conversation to investigate. Compare the live exact-variant price, finish, availability and installation package rather than assuming the family price relationship will stay fixed through promotions.

Dimensions: compare exact size to exact size

The current 10x10 evidence for both families lists approximately 121.16 by 121.16 by 98.74 inches. The current 10x13 evidence lists approximately 157.17 by 121.16 by 98.74 inches. That makes 111S and 111DA unusually clean size-matched comparisons in the variants we currently track.

Nominal labels still do not replace a site plan. Confirm post positions, base plates, drainage outlets, nearby doors, gutters, utilities and circulation clearances before ordering either family.

Warranty and engineering documentation

The current product data we track lists a 4+1-year warranty for 111DA and a 3+1-year warranty for 111S. We also currently have engineering-document availability recorded for 111DA while the 111S exact rows do not have that same evidence flag.

For a permit-sensitive or weather-sensitive project, documentation quality can matter as much as a headline specification. Ask for the exact-size engineering and installation packet before treating either family as approved for a specific site.

Which Mirador family should you shortlist?

Choose based on the constraint that matters most for the project, not simply on model number.

• Shortlist 111DA when all-aluminum construction, the higher current published wind/snow figures, the wider stated louver opening and the longer listed warranty matter most.
• Shortlist 111S when a value-oriented manual louvered kit is the priority and its lower published weather figures still fit the evidence requirements you have for the project.
• For either family, compare the exact size, live price, anchoring conditions and local requirements before purchase.
