One sealed unit, priced before you pay.\u003c\/p\u003e\n\u003cp\u003eYour window looks permanently foggy, and no amount of cleaning is even coming close to touching it, because the haze is between the two panes where you can't reach. Or one of the panes in a double-pane window cracked, and the local shop wants to sell you a whole new window when all you need is the glass. The seal failed, the unit's done, and you need a replacement sealed unit in the exact size to drop back into the frame you already have.\u003c\/p\u003e\n\u003cp\u003eThat's our job here. You enter the size and overall thickness, pick your glass type and options, and get a price on the spot. Then it's built, sealed, packed to survive freight, and shipped to your door.

None are dealbreakers. Knowing them up front helps you order the right unit the first time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA sealed unit can't be cut down after it's built.\u003c\/strong\u003e Two panes are bonded to a spacer and sealed around the edge as a single unit. Cut into that, and the seal breaks and the unit's ruined. So your width, height, and overall thickness all have to be right before it's made. It's a non-returnable, made-to-order item, so measure twice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe fog is a failed seal, and only a new unit can fix it.\u003c\/strong\u003e That cloudy haze between the panes is moisture that got past a broken edge seal. You can't clean it out, because it's on the inside surfaces you can't reach. Replacing the sealed unit is the fix, and the frame and sash you have can usually stay put.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYou're ordering the whole unit, not a single pane.\u003c\/strong\u003e The spec that trips people up is overall unit thickness: Measurement should include pane plus air gap plus pane, usually somewhere from 1\/2\" to 1\". This is a different number from the single pane thickness on our other glass products. Measure the thickness of the old unit's edge, or the depth of the sash pocket it sits in. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAll Insulated Glass Units Are Tempered Glass.\u003c\/strong\u003e While tempered glass is not necessarily required in all cases, many building codes require windows to be tempered glass, and that is generally the best option.

A sealed unit has different options than a single piece of glass, so don't expect edge or corner choices here.

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. \u003c\/p\u003e\n\u003cp\u003eA sealed unit has a third measurement: overall thickness. Hold a tape or caliper to the edge of the old unit and measure pane to pane, including the air gap in between. Round to the nearest 1\/16\". If the old unit is already out and broken, measure the depth of the sash pocket that the glass sat in. Write the spec as width x height x thickness.\u003c\/p\u003e\n\u003ch2\u003eGetting It to You in One Piece\u003c\/h2\u003e\n\u003cp\u003eEach order ships in a protective crating built for freight, with edge and surface protection, and it's insured, with tracking.

You'll also see it called an insulated glass unit, or IGU, or a double-pane unit. It's the glass that goes inside a double-pane window.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003eWhy is my double-pane window foggy, and will a new unit fix it?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe fog is moisture trapped between the panes after the edge seal failed. It's on the inside surfaces, so cleaning never works. A new sealed unit replaces the failed one and clears it up, and you keep your existing frame.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003eCan I replace just the glass instead of the whole window?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eUsually, yes. If the frame and sash are sound, you can replace the sealed unit inside them and not worry about the whole window. Measure the old unit's width, height, and overall thickness, and build the replacement in the customizer to match.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003eCan a sealed unit be cut to size after it's made?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eNo. The two panes are sealed to a spacer as one piece. Cutting it breaks the seal and ruins the unit. Every dimension, including overall thickness, has to be set before it's built. It's a made-to-order, non-returnable item, so measure carefully.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003eHow do I measure for a replacement sealed unit?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eMeasure the glass width and height in a few spots in case the opening isn't square, then measure the overall thickness at the edge, pane to pane, including the air gap. Write it as width x height x thickness.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cmeta charset=\"utf-8\"\u003eWhat overall thickness do I need?\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eMatch the unit you're replacing, or the depth of the sash it sits in.
