Fire Rated Aluminum Windows for Commercial Buildings in Israel

t395-33

Fire rated aluminum windows are window assemblies built with fire-resistant glazing and certified frame systems that slow the spread of fire and smoke between compartments of a commercial building. They combine the light weight and corrosion resistance of aluminum with glazing and seals tested for a required fire resistance period. Specifying the right rating and fitting them to measure is what makes them work as intended.

What makes an aluminum window fire rated

A fire rated window is not just a regular aluminum window with thicker glass. It is a complete assembly: the frame profile, the fire-resistant glazing, intumescent seals, and the fixings are designed and tested together. Under heat, the intumescent materials expand and close gaps, while the glazing holds its integrity and blocks flames and hot gases for a set period.

Because the performance depends on the whole system, mixing components from different sources can void the rating. Always confirm that the frame and glazing were tested as a combination.

Choosing the right rating for your building

The required fire resistance period depends on the building's use, height and the wall it sits in. Fire rating is usually expressed as integrity (E) and insulation (I) classes. Integrity keeps flames and smoke out, while insulation limits the temperature rise on the far side.

Corridors and escape routes often need the highest integrity.
Walls separating apartments or units may need both integrity and insulation.
Facade windows near a neighboring building may be governed by distance rules.

Your fire engineer and the local authority set the requirement. We never guess a rating; we build to the documented one.

Design details that affect performance

Good design keeps the rated assembly intact. Frame depth, glass thickness and the wall opening all matter. Fixed panels are simpler to certify than opening sashes, so consider fixed lights where ventilation is not essential. Where a sash is needed, it must have a tested closing and sealing arrangement.

Plan the wall opening early so the frame fixes into solid construction and the perimeter gap can be sealed with approved fire-stopping material. Coordinate with the wall system and the drawing package before fabrication begins.

Our process for fire rated projects

Every project starts with your drawings or with a site visit to measure the openings. We then prepare a written specification that lists the frame system, glazing type, seals, hardware and finish, so you can check it against the required rating before approval.

Coordinating with architects and building managers

Architects need clear documentation, and building managers need assurance that the installed units match the approved design. We provide shop drawings, the specification of each assembly and clear labeling of the rated units on site. Please share the rating requirement at the start so it is reflected in every drawing.

For building managers, keeping the paperwork for each rated opening simplifies future inspections and maintenance.

Installation, sealing and maintenance

Even a correctly rated product fails if installation is poor. The perimeter gap must be filled with the approved fire-stopping material, and fixings must follow the tested method. Avoid painting or modifying seals, and do not replace glazing with a non-rated type.

Inspect the seals and hardware periodically, especially on operable units, and report any damage so it can be repaired with the correct components.

Frequently asked questions

Can any aluminum window be made fire rated?

No. Only assemblies tested and certified as a complete system can be rated. A standard aluminum window cannot be upgraded by simply changing the glass.

Do fire rated windows need to be fixed, or can they open?

They can open, but the sash must have a tested closing and sealing arrangement. Fixed lights are generally simpler to certify.

Who decides which fire rating my building needs?

The fire engineer and the local authority determine the requirement based on the building's use, height and wall position. We build to the rating documented in your project.

Can you make fire rated windows to measure?

Yes. We manufacture to measure in our Tel Aviv factory, starting with on-site measurement and a written specification for your approval.

Common mistakes to avoid

The most common error is specifying a fire rating without confirming the complete tested system, or replacing rated glass with a standard type later. Both can invalidate the rating even if the frame looks correct.

Our recommendation

Share the required rating with us at the start, and let the fire engineer approve the specification before production. Keep the documentation for each rated opening with your building records.

Summary

Fire rated aluminum windows protect commercial buildings when they are specified, built and installed as tested systems. Define the required rating early and match every component to it.
