The doors are why most Treasure Valley homeowners meet All Weather Architectural Aluminum at all. A modern house with a wall that opens to the patio wants aluminum for the same reasons a storefront does: slim stiles, panels that can be twelve feet tall, and a frame that stays straight under a few hundred pounds of glass. All Weather builds two systems for that job, the Series 8100 multi-slide and the Series 8150 two-track slider, and they cover the range from a big patio door to a disappearing wall.
Series 8100: The Multi-Slide
The 8100 is a pour-and-debridge thermally broken frame with strutted panels, marine glazed, in 6063-T6 aluminum. It stacks flush in a true bypass, pockets into the wall so the opening is completely clear, or turns a 90-degree corner so two walls open at once. There is no limit on tracks or panels. Each panel runs 24 to 96 inches wide and 48 to 144 inches tall, to 70 square feet of glass, riding on 3-inch stainless tandem rollers or the heavier Quadzilla roller for the biggest panels. Sills range from a ¾-inch low profile to a 2-inch weeped sill and a recessed tile-in option, and a block frame with stucco return is available. Flush or D-pull handles, a keyed lock, and a retractable screen option round it out.
Tested at CW-PG30 in XO and XXO configurations, with design pressure of plus or minus 30 psf, air infiltration of 0.29 cfm per square foot and water resistance of 4.59 psf. An impact-rated version carries DP25. Sound transmission class runs to 38. NFRC U-factors are 0.31 to 0.39 with SHGC from 0.21 to 0.31.
Series 8150: The Two-Track Slider
The 8150 is the simpler system: a single-piece two-track frame, 3¾ inches deep, pour-and-debridge plus struts, in a true nail-on or block frame. It runs OX, XO, OXO or OXXO to four panels, with the same panel dimensions as the 8100. Rollers are 1.8-inch tandems rated to 600 pounds or Quadzillas to 1,200. Sills are 1⅞ inches or a ¾-inch low profile.
It tests higher than the 8100, at C35 under NAFS-17, with plus or minus 35 psf design pressure, 0.23 cfm per square foot air infiltration and 5.43 psf water resistance, and its U-factor reaches 0.30, the only All Weather door the company flags as meeting California's prescriptive line. It is what we specify when a project wants one big patio door rather than a wall that vanishes.
The Thermal Question
A forty-foot glass wall is a decision about heat loss before it is a decision about doors, and we say that on every big-door project regardless of brand. The 8100 at 0.31 to 0.39 and the 8150 at 0.30 to 0.32 are in the same range as the Andersen and Milgard systems we sell; all three are dual-pane aluminum or clad assemblies with a lot of edge. We model the wall in the whole-house UA calculation, pair it with Solarban 70 glass on south and west exposures, and design the overhang with the architect. Aluminum's advantage is that the frame will not move; its disadvantage is conductivity, which the thermal break is there to address and does not eliminate.
Where They Fit
The 8100 belongs on a modern home opening a great room to a covered patio, especially where a pocketing or corner configuration is part of the design and where matched Series 6100 or 6200 windows carry the aluminum look around the house. The 8150 is the answer for a large single opening, a 16-foot patio door in an existing wall, where installing like a window matters. Where we steer people elsewhere: a home that wants wood inside, where Andersen's MultiGlide or Marvin's Scenic Doors fit; a project that needs factory motorization, which All Weather does not offer; and a budget that needs the lifetime frame warranty Milgard puts on its moving glass walls.
Installation, Warranty and Service
The 8100 ships as glazed panels with a knocked-down frame, and the sill has to be set dead level in a pan or the panels will never track right. That is not a subcontractor job, and every All Weather door we sell is installed by Wood Windows employees who set these systems regularly. All Weather's residential warranty covers parts for ten years and labor for one year for the original purchaser, with glass over 70 square feet under the glass maker's terms and a twenty-year Kynar finish option. Service comes from our Garden City shop.

Frequently Asked Questions
What is the difference between the Series 8100 and Series 8150?
Track count and how far you want to go. The 8100 is All Weather's true multi-slide: unlimited tracks and panels, panels that stack flush in a true bypass, pocket into the wall, or meet at a 90-degree corner, with panels to 96 by 144 inches and 70 square feet each. It is the system for opening an entire wall. The 8150 is a two-track sliding door on a single-piece 3¾-inch frame, limited to four panels in OX, XO, OXO or OXXO layouts, with a true nail-on or block frame and a higher C35 structural rating. It is the system for a large patio door that installs like a window. The 8150 also carries the better U-factor, as low as 0.30, and is the only All Weather door the company flags as meeting California's 0.30 prescriptive line.
How does the All Weather multi-slide compare with Andersen and Milgard big doors?
It is the aluminum answer, and the material sets the trade-offs. Andersen's MultiGlide and Milgard's AX650 are the systems we sell most for wide openings; Andersen is clad wood or Fibrex with a twenty-year glass and finish warranty that transfers, Milgard is aluminum with a lifetime mainframe warranty for the original owner and no labor coverage. The 8100 sits between them on price with the slimmest stiles of the three, true flush stacking, a 90-degree corner option, and a ten-year parts warranty. On energy the three are close, all in the low-to-mid 0.30s dual-pane. We quote all three on any big-opening project and let the layout and the budget decide.
Can the Series 8100 be motorized or screened?
Screened, yes; motorized, not by All Weather. A retractable screen is an option on the 8100 that tucks into the jamb when open. All Weather publishes no motorization option for the 8100 or 8150, and although its warranty mentions electric motors and drive units at one year, that language covers any powered accessory rather than a factory automation package. If a motorized wall is essential, Andersen's MultiGlide automation is the system we would point to.
