Whatever your requirements, we can manufacture a modular rooflight system that not only meets these needs but does so while maintaining the high build quality, contemporary design, and exceptional safety standards that you would expect from EOS.
A bit about the different rooflight options
Fixed flat glass rooflights
Non-opening flat glass rooflights can be made to any size using minimal glazing bar for support. This system is a thermally efficient, cost effective way to transform a space and fill your home with light.
Fixed and Opening rooflights
Suitable for flat or sloped roofs, the opening rooflights in the EOS-97 line, include a fully insulated upstand with integrated hidden motors, creating a slim-line contemporary, thermally efficient rooflight.
Walk On rooflights
Walk-on rooflights are designed and tested so that they can withstand people’s weight. They can be built to specifications for residential or commercial customers to run seamlessly with floor finishes.

EOS97 Fixed Only
Modular Rooflight
Our fixed-only modular system allows for slimmer sightlines between panels by using a glass or aluminium fin, creating a clean, uninterrupted run of glazing ideal for flat roof applications.
Easy installation and
guaranteed compliance
At EOS, we prioritize convenience and ease of installation. Our modular rooflights are delivered as individual units, simplifying transportation and handling. With a straightforward bolt-together process, assembling the units is quick and hassle-free, ensuring a seamless installation experience for our customers.
Attention to detail, without compromising on design
Connecting extensive glazed areas can be accomplished through several techniques. For smaller spans, using a silicone seal to join the panels is an effective solution, offering a minimalist ‘frameless’ look. However, for larger spans, more robust supports are necessary to ensure the joints between the glazed panels remain secure and stable.

The adaptable EOS97 system can be customized with aluminum structural fins installed back-to-back. These aluminum angles are ideal for modern and contemporary interior designs, especially when integrated with bi-fold or sliding door systems. The internal angles can be powder-coated in any RAL color to match your design preferences. The size of the aluminum fins is determined by the width of the span, and for exceptionally wide spans, reinforced box sections can be utilized to provide the necessary strength and support.
