You already know your measurements and the thickness you need, but your local glass shop doesn't do one-off small pieces. Either their minimums are more than the actual glass costs, or they are a week or more out. That's where Flash Glass comes in. You can order online and get it shipped fast and safely to your door.
All you need to do is enter your measurements, pick your edge finish, corner customizations, and any holes that need to be cut, and you'll see your pricing on the spot. Then we'll cut it, temper it, pack it using the best glass-packing techniques in 100% recyclable materials, and send it right to your doorstep. So you don't even need to take a trip or put it awkwardly in your back seat.

Tempering is a heat treatment, and it changes two things: It makes the glass up to four times stronger than standard glass of the same thickness, so it holds up as a tabletop, loaded shelf, or bumped panel. It also changes how the glass breaks. Instead of long, jagged shards, it crumbles into small, blunt pieces. That's why most building codes require it in doors, shower and tub enclosures, and glass near the floor. If your project is one of those, tempered glass likely isn't optional.
Tempered glass also handles sun and everyday heat better than standard glass, but it is NOT fireplace or woodstove glass. For those, you need ceramic glass rated for higher heat.
Tempered glass can't be cut, drilled, or edged after it's tempered. Trying to do any of that will cause it to shatter. Tempering puts the surface under tension, and any later cuts will release that tension all at once. So your size, edges, corners, and holes have to be set before it goes through the furnace. Measure twice, and get your holes right in the order, because there's no trimming it later. Unsure about the cutout? Let us know on our contact page.
Our online builder takes you through every step of the process:
Custom glass is cut to the numbers you provide, so it can't be returned for a sizing mistake. Measure the opening, not the frame, and check the width and height in a few spots in case it isn't square. Allow a small gap where the glass sits in the channel (at least 1/16"), and write it as width x height in inches and fractions.
Each order ships in a protective crating built for freight, with edge and surface protection, and it's insured, with tracking. Inspect it before you sign, and if anything arrives broken, our breakage replacement policy covers it: Report it with a photo within 48 hours of delivery, and we'll make it right, with your replacement glass arriving within 5 business days.
Designers, contractors, cabinet makers, property managers: reorder the same specs without rebuilding them, quote jobs against one transparent (pun absolutely intended) price, and reach a real person for the odd cutout or batch run.
No. Once it's tempered, it can't be cut, drilled, or reshaped in any way without shattering it, so every detail is set before tempering. Measure carefully and mark all holes in the order.
Yes to both. It's about four times stronger than standard glass of the same thickness, and it breaks into small, blunt pieces instead of sharp, jagged shards, which is why most building codes require it in doors, showers, and glass near the floor.
It depends on thickness, size, edges, corners, holes, and shipping. The customizer will show you your exact total before you pay.
1/8" to 1/2", and up to 48"x48", and as small as 4"x4"
Yes, for most glass thicknesses, as long as holes are set before tempering. Send a drawing for complex shapes.
No. Fireplace and woodstove glass needs ceramic glass, which is made specifically for high-heat situations. Regular tempered glass isn't rated for that kind of heat.
Enter your size, pick your edges and holes, and get your number instantly. It'll be cut to spec, tempered for strength, and packed to arrive whole.
