Flat roof window - lots of natural light and a safe roof access

Roof hatches

Glass roof hatches, designed as flat roof windows, not only bring in natural light and ventilation but also bring about aesthetic and practical advantages suitable for both residential and commercial structures. With outstanding thermal insulation features and a sturdy build, these windows serve as an optimal substitute for conventional skylights, offering the added benefit of roof access possibilities.

Advantages of Gorter Flat Roof Windows

• Energy-efficient

The entire construction is thermally insulated. This, together with the HR+++ glass, ensures excellent insulation and a comfortable climate in the underlying space. Furthermore, the glass is equipped with a heat-reflective coating, which enhances thermal regulation both in summer and winter.

• Maximum light transmission and protection

The Gorter® glass roof hatch with its large surface provides maximum light transmission, but it also ensures 100% filtering of incoming UV light, protecting furniture and other items in the space below. Additionally, the glass is fall-safe and burglary-resistant.

• Ventilation with potential roof access

As standard, the Gorter® glass roof hatch is equipped with two powerful electric motors that allow it to be opened for ventilation purposes. The opening is stepless, allowing you to choose any ventilation position. If you combine the roof window with a Gorter fixed staircase, you can also use the whole system for complete safe roof access.

Different Variations of Flat Roof Windows

The Gorter glass roof hatch is available in four sizes ranging from 1000 x 1500 mm to 900 x 3000 mm. Additionally, the flat roof windows are available in various versions with a Gorter fixed staircase for safe and certified roof access.

Installation and maintenance of Gorter Flat Roof Windows

Gorter Flat Roof Windows can be used on flat roofs with a maximum slope of 5°. They can be installed on both existing and new roofs. The glass panel is angled to allow water to run off, making the flat roof window self-cleaning. For more information on installation and maintenance, please refer to the manual or visit our page on the installation of a roof hatch.
