Aluminum Window Order Specification Checklist With Glass Options

t400-36

A complete aluminum window order specifies the exact opening dimensions, frame profile and color, opening type, and every glass option such as thickness, coating, and safety or acoustic requirements. Writing these details down before production prevents measurement errors, mismatched glazing and costly changes. Send the specification with photos and a site measurement so the factory can draw and confirm it before manufacturing starts.

Start With Accurate Measurements

Measurements are the foundation of every window order. Record the width and height of each rough opening at several points, because walls are rarely perfectly straight. Note whether the opening is measured inside the frame, to the outer edge of the reveal, or to the finished plaster line, and state that clearly on the order.

Width and height at top, middle and bottom
Depth of the wall reveal
Sill and lintel heights

Every window should be measured on site before drawing begins.

Define the Frame and Profile

Specify the aluminum profile system, frame depth, and whether the window is a standard or thermally improved section. Mention the color and finish, such as a standard powder-coated color or a wood-look or steel-look finish, and whether the interior and exterior faces should match. Add any hardware details, including handles, hinges, locks and screen compatibility.

Choose the Opening Type

Indicate how each window opens. Options include fixed, casement, tilt and turn, sliding, and top-hung. For each sash, note the opening direction as seen from outside, since this affects where handles and hinges are placed and how the window fits the room. Mark any sashes that must be fixed for safety reasons.

List Every Glass Option

Glass is where many orders go wrong, so write it out in full for each unit. Specify the glass type, total thickness, number of panes, and gap or spacer type for insulated glazing. Also state the coating or tint, any safety glass requirement such as laminated or tempered glass, and any acoustic or privacy needs such as obscure or frosted glass.

Glass type and thickness per pane
Insulated or single glazing
Coating, tint or obscure finish
Laminated or tempered requirement

Add Safety and Installation Notes

Mention where windows are located in relation to floors, balconies or low sills, since this may affect glass choice and whether a guard or stopper is needed. Describe the wall type and the installation method, and note any existing frames that will be removed. Where railing or guard requirements apply, the Israeli railing standard SI 1142 is relevant, but exact values should be confirmed with your engineer.

Review, Approve and Confirm

Before production, the factory should send a drawing and written specification for your approval. Check each window number against the room plan, confirm dimensions and glass details, and sign off only when every item is correct. Keep a copy of the approved specification with your order records, so any later question can be answered quickly.

Frequently asked questions

What dimension should I give for an aluminum window order?

Give the exact measured width and height of the opening at several points, and state whether the measurement is inside the frame or to the finished wall. Include the reveal depth as well.

Do I need to specify glass type on every window?

Yes, every window and every glass panel should have its own glass specification. Different rooms often need different glass, such as privacy glass in bathrooms or safety glass near floors.

Can I change the glass after the order is approved?

Changes are possible before production starts, but they may affect timing and the final drawing. Confirm any change in writing so the approved specification stays accurate.

Why is a drawing important before production?

A drawing shows the exact sizes, opening directions and glass layout for each window. It lets you catch mistakes before materials are cut and assembled.

Common mistakes to avoid

The most common errors are measuring only once and ordering glass without stating thickness or safety requirements. Both can lead to windows that do not fit or glass that does not meet the room's needs.

Our recommendation

Send photos of each opening, the room use and a site measurement together with your specification, and ask for a written drawing to approve before production begins.

Summary

A clear aluminum window order covers accurate measurements, frame and color, opening type and every glass option, all confirmed in a drawing before manufacturing.
