Intura: specialists in daylight solutions for flat roofs
Intura · specialists since 2014
Daylight on flat roofs is not a product. It is a specialism.
Intura is the only specialist that approaches the full range of daylighting requirements for flat roofs as a single, comprehensive range: from fixed flat roof windows to ventilation, roof access, walk-on glass, light tunnels, rooflights, smoke vents and fully bespoke solutions tailored to specific projects.
For architects, contractors, roofers, dealers, housing associations and private builders.


An early choice for glass
Back when the market was still dominated by plastic domes, Intura had already opted for flat glass.
When Intura started in 2014, for many suppliers, daylight on a flat roof was virtually synonymous with a domed plastic dome. Intura saw things differently. A daylight opening should not only let light through, but also meet modern requirements for insulation, safety, comfort and architecture.
That is why, from the very beginning, Intura built up expertise in flat-glass flat roof windows and complete insulated systems. That early focus has led to years of practical experience with dimensions, glazing, upstands, waterproofing, condensation, ventilation, solar gain and installation.
- Flat glass as a fully-fledged building product
- HR++ and later HR+++ glazing
- Complete insulated systems
- From standard sizes to bespoke solutions
- Experience in renovation and new-build projects
- Developed from real-world projects
More than ten years ahead of the curve
From an alternative to the dome to a complete daylighting platform.
Intura’s edge lies not only in its history or product range. Its strength lies in the combination of product knowledge, project experience and the ability to offer a suitable solution for virtually any flat-roof situation.
Flat glass as the new standard
Intura was quick to position the glass flat roof window as a sustainable, insulating and architecturally appealing alternative to the traditional plastic skylight.
From light to function
In addition to fixed windows, the range includes electric ventilation, sun protection, roof exit hatch, walk-on glass, light tunnels, rooflights and smoke and heat extraction systems.
Standard and project-specific
Products available for immediate delivery are combined with large, circular, openable and fully bespoke daylighting solutions.
One specialist, every function
A range that covers all daylight requirements for flat roofs.
Many suppliers specialise in a single category. Intura, however, combines all the relevant functions: bringing in daylight, ventilating, limiting solar heat gain, providing access, keeping a terrace accessible, extracting smoke and enabling unique architectural designs.

Daylight on a flat roof requires more than just good glass.
Performance stems from the complete system and its integration with the building. That is why, when providing product advice, Intura takes into account not only the glass dimensions but also the components listed below.
From standard to premium
The right solution starts with the application.

Where standard solutions end
Round, extra-large, composite or entirely bespoke.
A specialist must also have a solution when standard sizes do not fit. Through FL Premium, Intura can deliver round fixed flat roof windows, long glass panels, large skylights, composite systems and combinations of fixed and electrically operated sections.
In this context, the form is never separate from the technology. Diameter, glazing configuration, upstand, supporting structure, colour, operation, roof covering and installation are assessed as a single project system.
- Fixed round flat roof windows
- Extra-large glazed areas
- Combining fixed and opening sections
- Electrically operated roof exit hatch
- Refurbishment of existing openings
- Project-specific colours and glazing
Knowledge partner for the project
Authority is built by sharing knowledge and taking responsibility.
Intura provides support beyond the purchase stage. Professionals gain access to installation guides, technical drawings, specification texts, product configuration and project-specific advice.
This allows the daylighting solution to be tailored earlier in the design phase to the supporting structure, roof construction, ventilation, fire safety and implementation. This reduces the risk of incorrect dimensions, missing connections or a product that does not fulfil the required function.
Frequently asked questions
Why choose a single specialist in flat-roof daylighting?
Why does Intura call itself a specialist in flat-roof daylighting?
Intura has been active in the field of glass daylight solutions since 2014 and combines fixed, ventilated, sun-shading and walk-on flat roof windows with roof exit hatches, light tunnels, rooflights, smoke and heat extraction systems and project-specific customisation. This enables us to provide advice based on the specific application rather than on a single product category.
What makes Intura’s product range exceptionally comprehensive?
The range covers not only light admission but also ventilation, summer comfort, roof access, walkability, smoke and heat extraction, and special architectural forms. Both standard products available for immediate delivery and large, round and composite bespoke solutions are possible.
Does Intura only supply glass flat roof windows?
No. In addition to glass flat roof windows, Intura supplies, amongst other things, light tunnels, bespoke wooden skylights, electric roof exit hatches, smoke and heat extraction hatches, and renovation solutions. The emphasis is on finding the right solution for the space and the roof.
Can Intura also manufacture a round or extra-large flat roof window?
Yes. Through FL Premium, round fixed flat roof windows, extra-large glass panels, long elements and composite systems can be provided on a project-specific basis. Technical feasibility is assessed on a project-by-project basis.
Does Intura support architects and contractors?
Yes. Intura provides support with product selection, installation guides, technical drawings, STABU specification texts, AutoCAD files, brochures and project-specific advice.
Where do I start when choosing a daylighting solution?
Start with the desired function: light only, or also ventilation, roof access, walkability, smoke and heat extraction (RWA), or bespoke solutions. Then gather information on dimensions, roof structure, roof covering, pitch, insulation and desired glazing. Based on this, Intura can determine the most suitable approach.
