Custom Aluminum Windows Made to Your Exact Measurements

t405-0

Custom aluminum windows are built to the exact dimensions of your opening rather than chosen from standard catalogue sizes. At Techno Kol Uzi, each window is measured on site, drawn to specification, approved by you, produced in our factory and then installed. This suits new builds where openings do not match off-the-shelf sizes.

When Standard Sizes Do Not Fit Your Build

Many new homes have openings that do not follow standard catalogue dimensions. Architectural designs, unusual room layouts and sloped or curved walls often call for windows that are narrower, wider or taller than typical stock. Ordering a standard size and filling the gap with extra frames or trim can look untidy and weaken the overall finish.

Custom aluminum windows solve this by starting from your real opening. Every unit is sized to the wall, so the frame sits neatly and the proportions match the design you planned.

How the Measuring Process Works

Accurate measurement is the foundation of a good window. We begin with an inquiry, where you can send photos of the openings and any drawings you have. Next, our team visits the site to measure each opening carefully, checking for level, square and any irregularities in the wall.

Measurements are taken at several points, because a rough opening is rarely perfectly even. The results are used to prepare a drawing and written specification that you review before anything goes into production.

Choosing the Profile, Glazing and Finish

Once the size is confirmed, you choose the details that shape how the window looks and performs. Options include the type of opening, the glazing and the colour finish. Powder coating offers a wide range of colours and a durable surface suited to the Israeli climate.

Your architect or interior designer is welcome to join this stage to keep the windows consistent with the rest of the project.

Production in Our Tel Aviv Factory

After you approve the specification, production begins at our workshop at 37 Rival Street in Tel Aviv. Because the work is done in-house, each frame is cut, assembled and finished to the measurements agreed. Working in one place means the drawings you approved are followed closely from start to finish.

Finishing steps are completed before delivery, so the windows arrive ready to install and require no major adjustments on site.

Installation and Fitting on Site

Installation is the final stage, and the quality of the fit depends on the earlier steps. Our team arrives with the completed windows and fixes them into the prepared openings, checking alignment, sealing and operation as they go. Any gaps around the frame are sealed to keep out water, dust and drafts.

Plan the installation timing with your contractor so the windows go in before the plastering and finishing work begins.

Who Benefits Most from Custom Windows

Custom aluminum windows suit homeowners planning a new build who need non-standard sizes, as well as contractors and architects working to a set design. They are also a good choice for building committees replacing windows across a block where consistent sizing matters.

If your project includes unusual openings, early planning gives you more freedom in design and a smoother schedule. Send us your plans and we will advise on what is practical for your openings.

Frequently asked questions

Do you measure the openings on site?

Yes. Our team visits the site to measure each opening, checking for level and square before a drawing is prepared. Exact checks are carried out by our team on site.

Can I see the drawing before production starts?

Yes. You receive a drawing and written specification to review and approve. Production begins only after your approval.

Can the windows match my architect's design?

Yes. Custom sizing, opening style and finish can all be coordinated with your architect or interior designer during the specification stage.

Where are the windows made?

All windows are manufactured at our factory at 37 Rival Street in Tel Aviv, where we have worked since 1945.

Common mistakes to avoid

A common error is ordering windows before the rough openings are finished, which leads to sizes that do not fit. Measure after the walls are built and confirm the dimensions before approving the specification.

Our recommendation

Confirm the final opening sizes with your contractor before ordering, and check the specification for opening style and glazing with your architect. For railing and safety details, the Israeli standard SI 1142 applies, and exact values should be checked with your engineer.

Summary

Custom aluminum windows are made to the exact measurements of your openings, from site measuring to factory production and installation. Planning early with accurate measurements gives the best fit for a new build.
