The size-and-type layer, priced apart
| Frame | Line, as published | 2026 band |
|---|---|---|
| Frame A | glass block window installation, per window | $600-$1,500 |
| Frame B | glass block window, total installed per window | $300-$1,500 |
Every figure here is a published line inside its own frame, never averaged into a single band. Window size is the first attribute a glass block quote names, block type the second. The project whole prices on the glass block hub; the room-build layer on the shower and wall guide.
Frame A size layer, as reported
| Window size, as published | Dimensions | Average per window | Range |
|---|---|---|---|
| Small basement window | 16x32 in. | $250 | $150-$1,400 |
| Standard bathroom window | 24x36 in. | $450 | $250-$2,800 |
| Large exterior window | 48x48 in. | $1,200 | $700-$3,900 |
Frame A prices size directly: three named sizes, each with an average inside a wide published range. The small basement average sits under the frame's $600 to $1,500 per-window band and runs past it at the top of its range; the averages are read inside their ranges, never outside them.
Frame A type layer, as reported
| Frame A line, as published | Reading | 2026 band |
|---|---|---|
| Glass block material | per block | $6-$12 |
| Acrylic block material | per block | $15-$25 |
| Blocks overall | per block | $6-$70 |
| Vented window type | average per window | $450 |
| Decorative / colored window type | average per window | $600 |
| Energy-efficient / insulated window type | average per window | $700 |
Frame A prints block material apart from window type: glass opens the per-block lines, acrylic sits above it, and the type averages price the finished window, not the block. The vented average is its own line, apart from the vent add-on Frame B prints on the shower and wall guide.
Frame B type layer, as reported
| Block material | Frame B, per block, before installation |
|---|---|
| Blocks overall | $10-$60 |
| Glass | $10-$60 |
| Acrylic | $15-$25 |
Frame B prints its own per-block table, labelled before installation, apart from any installed total. Its blocks are printed as 6- to 8-inch squares at 2 to 4 inches thick, as a reported attribute only.
Frame B style layer, as reported
| Pattern or style, as published | Frame B, per block, before installation |
|---|---|
| Clear | $10-$20 |
| Alpha | $10-$25 |
| Wavy | $10-$25 |
| Leathered | $10-$40 |
| Diamond | $10-$60 |
| Frosted | $15-$50 |
| Ice | $15-$50 |
| Color | $20-$60 |
Frame B prints eight style lines, each a per-block price before installation. Clear opens the table and color closes it, with frosted and ice in the middle. The same style name can sit in both frames at different readings -- the two tables print apart, never merged.
