Bring natural light, fresh air and modern convenience into your home or commercial project with the EOS97 Electric Opening Rooflight — a premium UK-manufactured rooflight system designed for flat and low-pitched roofs.
The EOS97 electric opening rooflight combines the clean, frameless appearance of a high-performance flat glass rooflight with the added benefit of controlled ventilation. Ideal for kitchens, extensions, stairwells, offices, commercial spaces and open-plan living areas, this electric rooflight helps brighten internal spaces while allowing warm air, humidity and stale air to escape at the touch of a button.
Manufactured to suit your project requirements, the EOS97 electric opening rooflight is available in bespoke sizes up to 4000mm, with a custom insulated upstand, concealed 24V motors and a choice of advanced glazing specifications.
Why Choose the EOS97 Electric Opening Rooflight?
The EOS97 is a premium electric opening flat rooflight designed for customers who want more than daylight alone. It provides natural ventilation, excellent thermal performance, clean internal sightlines and a high-quality architectural finish.
Whether you are specifying rooflights for a residential extension, commercial fit-out or new-build project, the EOS97 electric opening rooflight offers a smart, secure and energy-efficient solution.
Where a project includes both fixed and opening rooflights, the EOS97 system is especially effective because it offers matching internal and external sightlines across the range. This helps create a consistent finish across multiple rooflights, avoiding the mismatched appearance often seen with alternative systems.
Key Benefits
Excellent Thermal Performance
The EOS97 electric opening rooflight delivers outstanding energy performance, with independently certified U-values of 1.22 W/m²K for double-glazed units and 0.88 W/m²K for triple-glazed units when installed with the 97mm insulated upstand.
This makes it a strong choice for projects where energy efficiency, heat retention and compliance with current building standards are key considerations.
Electric Opening Ventilation
The EOS97 electric rooflight comes as standard with a pre-fitted 24V motor and a standard wall switch, allowing easy operation for day-to-day ventilation.
Opening rooflights are particularly useful in kitchens, bathrooms, stairwells, offices and large open-plan areas where heat and moisture can build up. By allowing warm air to rise and escape naturally, the EOS97 helps improve indoor comfort and air circulation.
Made to Measure Available
Every project is different, which is why the EOS97 electric opening rooflight can be manufactured to suit your specific requirements. Bespoke sizes are available from 650mm up to 4000mm, making it ideal for projects where standard rooflight sizes are not suitable.
For made to measure pricing, glazing options and specification support, contact Sterlingbuild for a quote and our team will help you choose the right EOS97 electric rooflight for your project.
Concealed 24V Motors
Unlike many competing systems, the EOS97 motor assembly is integrated within the insulated upstand. This removes the need for an additional external aluminium motor housing, helping to reduce the overall installation height by approximately 100mm.
This creates a cleaner, lower-profile appearance while also reducing cold bridging and improving the overall thermal performance of the rooflight system.
Integrated Insulated Upstand
The EOS97 electric opening rooflight is supplied with a purpose-made insulated upstand, designed to improve thermal efficiency and simplify installation.
The integrated upstand helps achieve a neat internal finish, a strong weather seal and a cleaner architectural appearance. It also allows the opening unit to match the sightlines of EOS97 fixed rooflights, which is a major benefit on projects using more than one rooflight type.
Smart Control Options
As standard the EOS97 Opening Rooflight comes with a standard switch with a built-in transformer. Additional upgrades include rain sensor, or smart control options for improved convenience and automation.
Available upgrade options include:
· Rain sensor upgrade
· Smart switch upgrade for phone control
· Smart switch and rain sensor package
· Voice control compatibility with Alexa, Siri, Google Home and Apple HomeKit
With smart controls, your rooflight can be operated remotely, programmed to open and close automatically, or set to react to weather and indoor conditions.
Safe, Secure and Robust
Each EOS97 electric opening rooflight is glazed with a heat soak tested toughened outer pane and laminated inner pane as standard. This supports impact safety requirements and provides additional protection for overhead glazing applications.
Heat soak testing reduces the risk of spontaneous glass breakage caused by nickel sulphide inclusions, while the laminated inner pane helps retain glass fragments in the event of breakage.
For commercial projects or applications requiring enhanced security, the outer pane can be upgraded to impact-resistant glazing meeting CWCT Class 1.
Contemporary Anthracite Finish
The external frame is finished in RAL 7016 matt anthracite grey, giving the rooflight a smart and modern appearance that suits contemporary extensions, commercial projects and flat roof designs.
The internal finish is clean and minimal, helping the rooflight blend seamlessly into the ceiling while maximising daylight from above.
Lid-Only Option Available
Already built your upstand? The EOS97 electric opening rooflight is also available in a lid-only configuration for installation onto a contractor-built kerb.
This version retains the same internal frameless appearance and thermally broken aluminium frame specification as the integrated upstand option, making it ideal for projects where the kerb has already been constructed.
Made to Measure EOS97 Electric Rooflights
The EOS97 electric opening rooflight is bespoke manufactured to suit individual project requirements. This makes it ideal for architects, contractors, builders and homeowners who need a premium opening rooflight in a specific size or glazing specification.
Made to measure electric rooflights are especially suitable for:
Kitchen extensions, Open-plan living spaces, Stairwells and landings, Loft conversions, Office spaces, Commercial fitouts, New-build projects, Architect-led residential designs, Projects requiring matching fixed and opening rooflights
