Why is gypsum a safe and sustainable building material?

Rigitone® boards do not emit any harmful chemicals.

Our products are based on gypsum, one of the earth’s natural resources. Gypsum does not contain substances that are harmful to the environment or toxic and does not release waste gases. These characteristics provide an excellent basis for a sustainable building material.

Why is indoor air quality becoming a critical concern in buildings?

As pollution levels have grown, attention has been given to understanding and managing the threats of outdoor air pollution on human health and the environment. However, it was only in the last few decades that any attention was paid to indoor air quality in terms of its effects on health and well-being.

Building materials, paint, flooring, furniture etc. may submit VOC’s (Volatile Organic Components) such as formaldehyde. It is harmful to indoor air and can create health issues for users of a building.

What are VOCs and how do Rigitone® ceilings help reduce them?

Construction materials, furniture, carpets, IT equipment and items of clothing all emit VOCs (Volatile Organic Compounds), such as formaldehyde. According to the World Health Organization (WHO), formaldehyde affects our health, and high concentrations can cause nausea, headache and other unpleasant symptoms.

Today, Rigitone® ceilings feature Activ’Air®, a patented technology that actively breaks up to 70% of formaldehyde down into harmless, non-volatile compounds. The effectiveness of the Activ’Air® technology has been tested by the accredited Eurofins laboratory.
