Aluminum sliding windows have a bad reputation in the Treasure Valley, earned by the single-pane, non-thermally-broken sliders that went into thousands of 1970s and 1980s homes and now sweat, frost and rattle. The Series 6200 is what a modern aluminum slider looks like, and it is the one window in All Weather Architectural Aluminum's line where the energy numbers need no apology. Here is why.
What It Is
A 3⅛-inch pour-and-debridge thermally broken frame in 6063-T6 aluminum, with square-cut mechanically fastened corners and marine glazing. Two-panel XO and OX configurations to 96 by 84 inches, three-panel XOX, and fixed transoms and bottom lites for taller compositions. Each sliding panel carries up to 28 square feet of glass and 180 pounds on Fapim hockey-style rollers, with an Amesbury Truth positive-action lock and a window opening control device available for bedroom egress compliance. Glazing is 1-inch dual-pane or 1¼-inch triple-pane with Cardinal or Vitro Low-E coatings. Class I clear or dark bronze anodized finish, Kynar paint on order.
Structurally it tests at CW-PG35 for the two-panel and LC-PG30 for the three-panel, design pressure of plus or minus 35 psf, air infiltration of 0.06 cfm per square foot at 6.27 psf, and water resistance of 5.43 psf. An impact-rated version carries DP25. Sound transmission class runs to 35.
The Energy Story
This is the part that separates the 6200 from the rest of the All Weather window line. Dual-pane units test at 0.31 to 0.32 U-factor, essentially at the 0.30 line we treat as the floor for a Treasure Valley home. The triple-pane package brings that to 0.25 to 0.26, which beats the typical vinyl slider we install and matches the best fiberglass. A slider has a structural advantage here: no crank, no hinge, no compression seal to leak, just an interlock and a track, so a well-made aluminum slider gets closer to its glass performance than an aluminum casement can.
Solar heat gain runs 0.18 to 0.33 depending on the coating, with Solarban 70 or LoE-366 at the low end for a west wall. All Weather does not claim ENERGY STAR and we do not claim it for them; the NFRC label on each unit is the number that counts.
Where It Fits
The 6200 is the right window in three situations. A modern home with All Weather multi-slide or bifold doors across the back, where matched aluminum frames on the sliding windows complete the look. A large opening that wants a slider, say 90 inches wide, where a vinyl slider of that size flexes and an aluminum one does not. And a replacement of those tired 1980s aluminum sliders in a home the owner wants to keep looking the same: a triple-pane 6200 in clear anodized drops into the opening with the same visual weight and a fraction of the heat loss.
Where we steer people elsewhere: a whole-house replacement on a budget, where a Milgard Trinsic or Tuscany slider does the job for less; any project that needs the ENERGY STAR label for a utility rebate; and exposed walls where a casement's compression seal beats any slider's interlock, in which case we pair 6200s on the sheltered sides with Series 6100 casements facing the wind.
Warranty and Service
All Weather's residential warranty covers parts for ten years and labor for the first year for the original purchaser, with twenty years on Kynar paint and one year on screens. That is shorter than the vinyl makers' terms, and we say so. What we add is the service side: Wood Windows is All Weather's Certified Dealer for the Treasure Valley, every 6200 we sell is installed by our own employee crews, and a roller or lock problem in year six is handled from our Garden City shop, not from Vacaville.

Frequently Asked Questions
Is the All Weather Series 6200 energy efficient enough for Idaho?
With triple glazing, yes, and it is the standout in All Weather's window line for that reason. A dual-pane 6200 tests at 0.31 to 0.32 U-factor, right at the edge of the 0.30 figure we use as a Treasure Valley floor. Order it with the 1¼-inch triple-pane package and it drops to 0.25 to 0.26, better than most vinyl sliders we install and comfortably inside code without leaning on the whole-house calculation. The slider format helps here: with no hinge or crank hardware to leak around, a well-built aluminum slider gets closer to its glass performance than an aluminum casement does.
How large can a Series 6200 slider be?
Each sliding panel runs 18 to 48 inches wide and 18 to 84 inches tall, capped at 28 square feet and 180 pounds, so a two-panel XO unit reaches 96 by 84 inches. A three-panel XOX configuration spreads a wider opening across a fixed center lite and two sliders. Fixed transoms above and bottom lites below extend the composition. Those are large numbers for a slider; a 96-by-84 vinyl slider would be a floppy proposition, and the aluminum frame is what makes it practical.
How does the 6200 compare with a Milgard or Andersen slider?
Narrower frame, bigger glass, longer life on the finish, and a different energy profile. A Milgard Tuscany slider is wider-framed vinyl at 0.27 to 0.30 U-factor dual-pane with a lifetime frame warranty; an Andersen 100 Series gliding window is Fibrex at 0.27 with a twenty-year glass warranty. The 6200 dual-pane lands at 0.31 and needs the triple package to beat them on energy, and its warranty is ten years on parts. What it gives you is a sightline neither can match, a true anodized bronze or clear finish, and the ability to match All Weather's doors across the back of the house. We sell all three and will quote them side by side.
