Fixed Skylight Window
Light from above changes a room differently than light from the side — it fills rather than falls across, reaching corners a window never could. A fixed skylight is built entirely around that effect: expansive insulated glass panels held by minimal visible framing, letting daylight pour into a space while the structure holding it up stays almost invisible against the sky.
That invisibility carries real engineering behind it. Thermally broken aluminium profiles, structural pressure plates, and advanced sealing systems are built to resist rain, wind, and air infiltration from directly overhead — the most demanding direction any glazing system faces — while remaining fixed, non-operable, and close to maintenance-free for the long term. It’s a system suited to atriums, hotels, and landmark developments where natural light is treated as part of the architecture, not an afterthought.
1. Maximum Natural Daylight
The system is designed to introduce abundant overhead daylight, reducing dependence on artificial lighting and creating bright, inviting interior spaces.
2. Thermally Broken Aluminium Profiles
Multi-chamber profiles with glass fibre reinforced polyamide thermal breaks minimize heat transfer, improving year-round energy efficiency even under direct overhead exposure.
3. Large Architectural Glazing
Expansive insulated glass panels with minimal visible framing create elegant roof glazing with uninterrupted views of the sky.
4. Superior Weather Protection
Advanced sealing systems, pressure-equalized drainage, and structural glazing technology provide exceptional resistance to rain, wind, and air infiltration from above.
5. Contemporary Architectural Design
Slim architectural profiles integrate seamlessly into modern residential and commercial roof designs, without interrupting the roofline.
6. Low Maintenance Construction
The fixed, non-operable design offers long-term reliability with minimal maintenance required, even in demanding overhead conditions.
Glazing spans double glazing at 28 to 44 mm and triple glazing at 44 to 60 mm, both available with Low-E coating, argon fill, and warm edge spacers, extending into clear, ultra clear low-iron, laminated, toughened, heat-strengthened, solar control, reflective, acoustic, self-cleaning, ceramic frit, and optional smart electrochromic glass. Safety is built specifically for overhead applications — laminated and toughened safety glass, optional heat-soak testing, structural glazing compatibility, fall-resistant configurations, and secure structural fixing systems all address the particular demands of glazing installed above occupied space.
Configuration covers flat and pitched roof skylights, continuous roof glazing, ridge and pyramid skylights, lantern roofs, modular systems, atrium skylights, and walkway roof glazing, finished in matte, fine texture, and metallic powder coating, anodized aluminium, wood grain sublimation, and custom RAL colours. That range suits luxury villas, hotels, shopping centres, offices, educational and healthcare facilities, museums, airports, exhibition centres, and mixed-use developments alike.
