All Weather Vantage & Viscount Patio Doors: Vinyl Slider Review

All Weather Windows Vantage & Viscount Patio Doors — Key Facts

Frame material: Welded uPVC sash and frame; Vantage available with exterior acrylic-wrap colour and black interior wrap
Design pressure rating: NAFS tested; Performance Grade varies by configuration and size — verify per unit at quote
Idaho winters: Vantage's Quad Seal interlock, two triple-fin weatherstrips and optional triple-pane glass were engineered for Alberta; the cold-glass draft you feel next to a 1990s aluminum slider in January is the problem this door was designed around
Idaho summers: White or Wicker uPVC stays cool on a west-facing patio; if you choose a dark acrylic-wrap exterior, pair it with ComfortPlus 270 or ComfortMax 366 glass and expect us to talk you through shade and exposure first
Wind exposure: A sloped frame and a true fixed sash on the Vantage resist wind-driven water; for open Canyon County lots we verify the NAFS Performance Grade of the exact configuration before ordering

What These Doors Actually Are

Both are uPVC sliding patio doors built in All Weather Windows' Edmonton plant, and they bracket the line. Vantage is the flagship — All Weather's first patio door offered with acrylic-wrap colour, designed to match wrapped windows like the Apex 9100 and Summit 9700. Viscount is the value door, which the manufacturer describes as a practical solution for cottages and new homes. Neither is a French door or a multi-slide; for those we point you to the patio door guide.

Configurations and Sizes

Vantage's asymmetrical two-panel deserves a mention because nothing else in vinyl does it cleanly: one wide fixed lite and a narrower operating panel across a 10-foot opening, which reads as a modern wall of glass without a mullion in the middle. The 8/0 height is the other differentiator — a standard 6/8 slider under a 9-foot ceiling leaves a header band that looks like an afterthought, and All Weather sized this door to fill that opening. Viscount stays conventional: two or three panels, standard heights, one operating panel with your choice of slide direction.

Exact rough-opening sizes for both doors are configuration-specific and come from the current order guide, not this page. We measure the opening, including the out-of-square you cannot see from inside, before anything is ordered.

Glass, Locks and Hardware

All Weather's published centre-of-glass numbers apply to door glass as well as windows: dual-pane ComfortPlus 270 with argon at COG U 0.25 and SHGC 0.37, triple-pane ComfortPlus 270 at U 0.12 and SHGC 0.31, and the high-gain ComfortGain 180 for north-facing doors that want free winter sun. Whole-door NFRC ratings run higher because a patio door is mostly frame at the edges and interlock; the number on the label is the one we quote. Door glass is tempered by code in every configuration.

On security, the Vantage's three-point lock engages top, middle and bottom of the interlock stile, which is the answer to the pry-bar weakness of single-latch sliders. Viscount's optional keyed handle and spring-loaded foot lock get a value door to a similar place for less. Both accept grilles and SDL; the Vantage adds cordless blinds sealed between the panes, which we recommend for anyone tired of cleaning slats next to a dog door.

Thresholds, Sills and Idaho Weather

A patio door fails at the sill before it fails anywhere else. The Vantage's sloped frame drains outward by design, and its two triple-fin weatherstrips plus the Quad Seal interlock are what stop the January draft at the meeting stile. What no manufacturer supplies is the sill pan and the flashing tie-in to your deck ledger or patio slab — that is our work, and it is where a Treasure Valley slider bought at a box store and set on bare subfloor rots the framing in eight years.

In McCall and Cascade the sill sees snow piled against it for months; we set the door height and the exterior threshold detail with that in mind, and the triple-pane Vantage is the default up there. On an unshaded west patio in Meridian or Nampa, white or Wicker uPVC stays dimensionally stable in August; if you want the Jet Black or Anthracite wrap, we will talk through exposure and glass first. Cross-border lead times apply to these doors as they do to All Weather's windows — ask for the current figure at quote.

Warranty and Service, Locally

All Weather's residential consumer warranty has covered insulated-glass seal failure and vinyl components for 20 years, coatings on vinyl for 10, workmanship for two and spontaneous glass breakage for one, transferable to the next owner of a single-family home; a revised guide took effect August 4, 2026, and we confirm the current terms on your order. Roller adjustment, weatherstrip replacement and any glass claim are handled by Wood Windows Inc's own employees from Garden City — the same crew that set the door, backed by 46 years of doing exactly this.

Frequently Asked Questions

What do the Vantage and Viscount cost installed?

Typical Treasure Valley installed pricing: a Viscount 2-panel slider runs about $1,800–$2,600, a Vantage 2- or 3-panel about $2,400–$3,800, and 4-panel, triple-pane or acrylic-wrap Vantage configurations climb above the usual vinyl-slider range. Old-door removal, threshold and sill work, and haul-away are included in our numbers. Firm written quote after a free measure — door openings are rarely square and we price the real condition.

Vantage or Viscount — which one should I buy?

Vantage if you want colour, a triple-lock, triple-pane glass, an 8-foot height or a 3- or 4-panel wall of glass — it is the door All Weather positions as its flagship. Viscount if you want a well-built white or Wicker slider for a cabin, a rental or a production build at the lowest price in the line, with a keyed handle and foot lock available for security. Same factory, same warranty.

Are these patio doors triple-pane?

Vantage offers triple-pane glazing as an option, and in McCall or Cascade we recommend it — a patio door is the largest single piece of glass in most homes and the first place you feel a cold night. Viscount ships with dual-pane Low-E argon glass; ask us about triple availability for a given configuration. Either way, door glass is tempered by code.

How long does an All Weather patio door take to arrive in Idaho?

Longer than a Milgard slider from Washington, because the door ships from Edmonton and clears customs on the way. Lead times move with season and the border, so we quote the current one in writing rather than guess here. Once it lands, a standard 2-panel replacement is a one-day install for our crew, including the new sill pan and flashing.
