What It Actually Is
A Crystalia frameless partition is a wall made of nothing but tempered glass and two slim aluminum extrusions: a top track that carries the sliding hardware and a 5/8" x 3/8" bottom channel that keeps fixed panels planted. There are no vertical stiles, no mullions, and no visible frame around the door — the glass edges meet at a 3/16" gap and the door runs on ball-bearing rollers with an anti-shock brake. The soft-close option uses nitrogen gas and oil-filled pistons, the same idea as a good kitchen drawer scaled up to a 200-pound door.
Glass is monolithic tempered at 3/8" or 1/2", in clear, low-iron, bronze, gray, or frosted. Crystalia caps monolithic tempered panels at 10 feet of height, which comfortably covers Treasure Valley ceilings from 8-foot ranch remodels to 9- and 10-foot new construction.
Within Crystalia's lineup this is the minimalist entry point. The steel-framed system adds divided-lite character, the aluminum and Kompas systems add perimeter seals and acoustic performance, and the sliding glass wall scales the frameless idea up to 12 stacking panels that can run outdoors. Crystalia builds all of it in Brooklyn, and Wood Windows Inc is the signed dealer for Idaho as of 2026.
Configurations, Glass and Hardware
Crystalia packages the frameless line as four standard systems, and we can mix fixed lites into any of them:
| System | Panels | Typical use |
|---|---|---|
| Single sliding door | 1 door | Pantry, closet, powder room |
| Single sliding + fixed | 1 door, 1 fixed | Home office off a great room |
| Double sliding doors | 2 doors, bi-parting | Dining room or den opening |
| Double sliding + two fixed | 2 doors, 2 fixed | Conference room front, wide room divide |
Swing doors on pivot or wall-mount hinges are available where a slider's wall run isn't there. Handles are your choice — ladder pulls, back-to-back bars, or a recessed flush pull for a door that stacks behind a fixed panel.
The top track measures 5/16" x 2-3/8" and can surface-mount to the ceiling or recess into a soffit so only a shadow line shows. The sliding door rides above a 1/2"-tall bottom guide instead of a floor track, which is the detail homeowners care about most: no channel to trip on, nothing to catch a vacuum.
Low-iron glass is worth a sentence. Standard clear glass has a green edge tint that stacks up visibly on a 1/2" panel; low-iron reads truly colorless. On a partition you look through all day rather than at, it's the upgrade we recommend most often.
Where It Fits in Idaho Homes and Offices
Three situations account for most of our frameless work. First, the open-plan remodel that went too far: 2000s-era Boise and Meridian homes with a great room that has no quiet corner, where the fix is a glass-enclosed office that keeps the sightline and the daylight. Second, new custom builds where the architect has already drawn a glass study or gym and the builder needs a dealer who will measure, fabricate, and install rather than hand them a crate. Third, commercial tenant improvements — conference fronts and private offices in downtown Boise and Eagle office parks — where frameless glass is the default look and the landlord wants demountable construction.
It pairs naturally with the shower door and mirror work we already do; the same tempered-glass handling, the same installers, one company holding the warranty. See our shower doors and mirrors page for that side of the business.
Where it doesn't fit: anywhere sound privacy is the actual job. A frameless slider screens sight, not noise. And a room without a true ceiling structure to anchor into — a finished basement with a drop ceiling, for example — needs reinforcement before glass goes up, which we build into the quote.
Codes, Safety Glazing and Installation
Every panel is tempered, which matters because Idaho's residential code (IRC R308) treats glass in and beside doors as a hazardous location requiring safety glazing, and commercial work under IBC 2406 does the same. Tempered glass per ASTM C1048 breaks into small cubes rather than shards; each Crystalia lite carries the permanent tempering logo an inspector will look for.
Installation is where a dealer earns its keep. Crystalia's program is dealer-installed, and in Idaho that means Wood Windows employees — the same carpenters and glaziers who set our windows and shower enclosures, not a subcontracted crew. We field-verify ceiling height at three points (they're never equal), confirm the anchoring substrate, and order glass to the sixteenth. Lead times from Crystalia's Brooklyn shop vary with the season and the glass type; we confirm a schedule at order.
Warranty and Service, Locally
Crystalia backs its systems with a manufacturer limited warranty; the specific terms for the frameless line ride with each quote, and we walk through them before you sign. The practical guarantee is closer to home: Wood Windows Inc has installed glass in the Treasure Valley for 46 years, and if a roller ever chatters or a door drifts out of alignment, the people who installed it drive out from Garden City to fix it.

Frequently Asked Questions
What does a Crystalia frameless glass partition cost installed in Idaho?
As a typical range, a single-door frameless wall for a home office — one fixed panel plus a soft-close sliding door across roughly 8 to 10 feet — runs in the neighborhood of $5,000 to $10,000 installed, depending on glass thickness, low-iron versus clear, hardware, and how much ceiling reinforcement the room needs. Wider openings, 1/2-inch glass, and frosted or tinted lites push it higher. We measure first and quote a firm number; there are no allowances or add-ons after the fact.
Should I choose frameless or Crystalia's steel-framed partition?
Frameless disappears; steel makes a statement. If the goal is to keep an open plan reading as open — a Meridian great room with a glassed-in office off the side — frameless is right, and it's the less expensive of the two. If the room wants a loft or French-door look with divided lites, the steel system earns its higher price. Both take the same 3/8-inch tempered glass, so the decision is aesthetic and budgetary, not a performance call.
How much sound does a frameless partition block?
Less than a framed system, and honesty matters here. Frameless sliders have a 7/16-inch and 3/16-inch running gap by design, so they soften conversation and screen a room visually, but they are not a sound-rated wall. If a client needs real acoustic separation — a podcast room, a nursery wall — we steer them to the aluminum or Kompas systems, which seal at the perimeter and publish a sound rating.
Do I need 1/2-inch glass or is 3/8-inch enough?
For most residential partitions under 8 feet tall, 3/8-inch tempered is the right choice: stiffer than it looks, lighter on the rollers, and less costly. We move to 1/2-inch on taller panels approaching the 10-foot limit, wide fixed panels with no intermediate support, and commercial lobbies where the glass will take incidental impact. Panel weight is the governor — the sliding hardware carries up to 242 pounds per door, and a 1/2-inch door hits that ceiling fast.
