Planning Glazing Openings in Aluminum Doors

Why glazing openings must be planned early

A glass insert is not simply a hole cut into a finished door. The frame profile, the glazing bead, the sealing gasket and the locking points all depend on how large the glass is and how thick it will be. If these decisions come late, the door may need redesign or the glass may not fit the profile chosen.

Planning early also helps you coordinate with the glazier, the architect and the installer. Each party sees the same drawing and knows which dimensions are fixed and which are still open.

Measuring the opening on site

Measure the door opening itself, not only the drawing, because walls are rarely perfectly square or level. Record width and height at the top, middle and bottom, and check diagonals to confirm squareness.

• Note the door swing direction and handing.
• Mark the position of hinges, locks and any existing fixtures.
• Photograph the surrounding wall and threshold.

Our team takes these measurements on site before any drawing is prepared, so the specification reflects the real opening.

Choosing the glass and its build-up

Decide early whether the insert will be single or double glazed, and what thickness suits the door size. Larger panels usually need thicker glass and more support from the frame, while smaller inserts give more freedom in choice.

Consider light, privacy and sound. Frosted, patterned or tinted glass changes the look of the door and how much daylight passes through. Confirm the final build-up with your engineer, as exact requirements depend on the project.

Safety and standards for glazed doors

Glass in doors may need to meet safety requirements, especially where people could walk into it or where the panel is near the floor. Clarify this at the planning stage, since it affects the glass type you select.

For railings and guards, the Israeli standard SI 1142 applies. Exact values for dimensions and loads should be checked with the engineer for your specific installation rather than assumed from memory.

Production and finishing in the factory

Once the drawing and specification are approved by the client, the frame is cut and assembled in our workshop at Rival Street 37, Tel Aviv. The glazing channels are machined to suit the chosen glass, so the insert seats correctly and seals well.

Iron elements are hot-dip galvanized for corrosion protection, and finishes such as powder coating are applied to match the design. Aluminum profiles are finished to the colour and texture agreed at approval.

Installation and final checks

On installation day the door is fixed into the prepared opening, levelled and checked for swing and alignment. The glass is then fitted and the beads and gaskets are set so the seal is even all round.

• Check the door closes smoothly and latches correctly.
• Inspect the glass for scratches or edge damage.
• Confirm the seals are complete and undamaged.

Any adjustments are made before the installer leaves the site.

Frequently asked questions

Should I measure the opening or the existing door?

Measure the opening itself, since walls and thresholds are often out of square. The existing door may be smaller or larger than the actual space available.

Can the glass type be changed after production starts?

Changes are costly and can delay the job, so the glass type should be confirmed in the approved drawing. Raise any change requests as early as possible.

Do glazed aluminum doors need a specific glass?

It depends on the door size, location and use. Discuss safety requirements with your engineer so the glass selected meets the relevant standards.

Why does the door need a written specification?

A written specification records the agreed dimensions, glass and finish. It protects both the designer and the client by fixing what will be produced.

Common mistakes to avoid

Designers often finalize the door design before measuring the real opening, or choose glass without checking the frame profile it must fit. Both errors lead to rework and delays.

Our recommendation

Measure on site, approve a written drawing that lists the glass build-up and finish, and confirm safety requirements with the engineer before production begins.

Summary

Plan glazing openings from the actual measurements, decide the glass and safety needs in advance, and approve a written specification before production. This keeps the door, the glass and the installation in step.
