Gorter® RHT roof hatch – SHI Certified Sustainable Product & QNG Ready

At Gorter®, safety and health go hand in hand in our innovative roof access solutions.

We are proud to announce that our RHT roof hatches have been officially certified by the Sentinel Holding Institute (SHI). This recognition confirms that our products meet the strictest requirements in the fields of health and sustainability. The roof hatches are therefore certified as a “Certified Sustainable Product” and also carry the “QNG Ready” quality mark.

What is the Sentinel Holding Institute (SHI)?

The Sentinel Holding Institute is the European authority in the field of “healthy building.” It applies strict, scientifically substantiated criteria to test building products for harmful substances and emissions. A product is only included in the SHI database if it demonstrably contributes to healthy indoor air quality and a safe indoor climate.

For architects and project developers, SHI registration provides the assurance of working with materials that prioritise the well-being of end users. Here you can view the official registration of the Gorter RHT roof hatches with the Sentinel Holding Institute.

The new certifications for the RHT roof hatch

The Gorter RHT roof hatches now carry the following distinctions:

Certified Sustainable Product: This certificate confirms that the roof hatches have been extensively tested for emissions (such as volatile organic compounds and formaldehyde) and are officially recognised as safe for use in healthy living and working environments.

QNG Ready: The roof hatch meets the requirements of the Qualitätssiegel Nachhaltiges Gebäude (QNG – Sustainable Building Quality Seal). This quality mark is essential for projects aiming for the highest sustainability certifications and may also enable access to specific green subsidies and financing options.
