Fire protection window F90

What is an F90 fire-resistant window and why is it so important?

An F90 fire protection window is a highly developed construction element that has been specially designed to prevent the passage of fire and smoke for at least 90 minutes in the event of a fire. This exceptionally long resistance period is mandatory in many public buildings, industrial facilities, escape routes and technical rooms in order to protect human life and preserve material assets. The F90 certificate guarantees that the window can withstand intense heat, flames and smoke - and not just for a few minutes, but for an hour and a half. In an emergency, an F90 fire protection window provides valuable time for evacuation and allows the fire brigade to proceed safely. The requirements for materials, design and workmanship are correspondingly high, meaning that only tested and certified windows may be used as F90 fire protection windows. Anyone who opts for this solution is investing in maximum safety and fulfils all legal requirements for demanding construction projects.

Five red fire extinguishers are mounted in a row on a green wooden wall, ideal for environments with fire-resistant windows or a fire-resistant door from Brandschutz Tischlerei Beelitz. Each extinguisher has a hose and white stickers with instructions and symbols on the front.
Large windows, possibly fire-resistant windows, are exposed to intense flames and heat, with the glass shattering and smoke rising from the left-hand side - an indication that a fire or a fire resistance test by Brandschutz Tischlerei Beelitz is in progress.

Technical innovations and construction of F90 fire-resistant windows

The design of an F90 fire-resistant window is based on state-of-the-art technology and a sophisticated selection of materials. Multi-layer special glazing, fire-retardant frame profiles and high-quality sealing systems work together perfectly to reliably ward off heat, smoke and flames. Special fire protection gel layers or intumescent materials are often used between the individual glass layers, which expand in the event of a fire and additionally seal the window. The frames are also made of non-combustible or flame-retardant materials that retain their shape and function even under extreme loads. Innovative seals ensure that no smoke gases can penetrate and that all connection joints remain permanently protected. Precise manufacturing and regular quality control ensure that every F90 fire-resistant window meets the strict testing standards and offers constant protection.

Advantages and added value of an F90 fire-resistant window

An F90 fire protection window not only offers invaluable benefits in an emergency, but also impresses with numerous added values in everyday life. Thanks to its special design, it contributes significantly to the safety of people and property and fulfils the high requirements of modern fire protection concepts. In addition, the high-quality glazing ensures excellent thermal insulation so that heating costs can be reduced in the long term. Many F90 models also offer sound insulation functions and can be combined with burglar resistance, making the window a versatile solution for a wide variety of buildings. Durability is also an important factor: the robust materials and careful workmanship ensure that an F90 fire protection window functions reliably for many years and requires hardly any maintenance. For building owners and operators, this means a sustainable investment in safety, efficiency and maintaining the value of the property.

Sustainability, environmental protection and funding opportunities

Beelitz attaches particular importance to sustainability and environmental compatibility in the development and production of F90 fire-resistant windows. Recyclable materials and innovative manufacturing processes that minimise the ecological footprint are preferred. The high energy efficiency and long service life of the windows help to conserve resources and keep operating costs low in the long term. In addition, there are numerous state subsidy programmes that provide financial support for the installation of F90 fire-resistant windows - both for new builds and renovations. Beelitz will be happy to advise you on all funding opportunities and guide you through the entire application process so that you can benefit from all the advantages.
