Clear Window Glass 12 × 16 in — Custom-Cut Single Pane

Clear 12 × 16 inch single-pane window glass, fabricated for exact-size replacement and project work. This listing is for one unframed clear annealed glass sheet with nominal finished dimensions of 12 inches wide × 16 inches high. Choose the available thickness that fits your application, or request a smaller custom finished size before fabrication.

Recommended uses

This clear glass panel is commonly considered for picture and photo frames, cabinet-door inserts, small display cases, craft or restoration projects, and compatible small window-sash repairs. The buyer or installer is responsible for confirming that the selected thickness, glass type, support, and edge treatment are suitable for the project.

• picture, photo, diploma, and artwork frames designed for real glass
• small curio, shadow-box, and protected display inserts
• compatible cabinet-door inserts and furniture restoration
• small interior sash panes after the finished size is professionally confirmed

How to select thickness

• 1/16 in (about 1.5 mm): lightweight applications such as compatible small frames and protected inserts.
• 1/8 in (about 3 mm): a common choice for many cabinet inserts, small panes, frames, and fully supported interior projects.
• 3/16 in (about 5 mm): added rigidity for larger panes or projects that require a heavier glass sheet.

Not every thickness is offered at every size. Select only from the variants shown on this product page. Thickness guidance is general information, not an engineering specification.

Measure before ordering

1. Remove or safely access the existing pane only if you are qualified to do so.
2. Enter the required finished glass size, not the rough opening, sash exterior, or frame size.
3. Measure width and height in more than one location and confirm the allowance required by your sash, frame, stops, and glazing method.
4. If the opening is out of square or the measurement is uncertain, request professional measurement before placing the order.

Custom fabrication options

The 12 × 16 inch sheet can be reduced to a smaller rectangular finished size before fabrication. Available quoted options include:

• Edges: standard seamed, flat polished, pencil polished, or beveled where feasible
• Corners: square, clipped, or radius corners
• Fabrication: drilled holes, notches, cutouts, and approved custom shapes
• Glass upgrades: tempering, lamination, tint, or another specialty glass type

Provide a dimensioned sketch showing finished width, height, edge finish, hole diameter, hole-center locations, notches, and corner radii. Feasibility and price are confirmed before production. All cutting, drilling, and edgework must be completed before tempering; finished tempered glass cannot be cut or drilled afterward.

Handling, cleaning, and installation preparation

Keep the pane upright, evenly supported, and protected at every edge and corner. Use appropriate eye, hand, and body protection plus professional handling equipment for larger panels. Do not install damaged or incorrectly sized glass. Clean with a soft cloth and non-abrasive glass cleaner. Glazing tape, blocks, sealants, stops, putty, and fasteners must be compatible with the frame and are sold separately.

Safety and code notice

Standard annealed glass is not safety glazing. Do not use this annealed product in doors, shower or tub enclosures, guards, railings, hazardous locations, or any opening that requires tempered or laminated safety glass. Applicable building codes, wind loads, human-impact requirements, support conditions, and installation details vary. Final selection and installation should be confirmed by a qualified glazing professional.

Order confirmation

Because cut glass is made to order, review the selected size and thickness carefully. Golden Window & Doors may contact you to confirm specifications, handling, lead time, and fulfillment before fabrication. For a non-standard size or safety-glass application, request a custom quote instead of ordering annealed glass by assumption.

Before checkout

• Confirm that 12 in × 16 in is the required finished glass size.
• Select the correct thickness from the available variants shown above.
• Confirm that annealed glass is allowed and contact us if the opening is irregular or code-regulated.
