When we talk about air pollution, we often think of exhaust fumes and industry. However, indoor pollution—the kind we breathe at home, at work, or at school—can be up to five times higher. And one of the major sources that’s often overlooked? Construction and renovation materials.

Invisibly toxic materials

Modern materials—paints, varnishes, glues, wood panels, insulation, and even flooring—can release volatile organic compounds (VOCs) into the air. These substances are released slowly (sometimes over years) and are associated with various health problems: headaches, nausea, irritation, respiratory problems, and even carcinogenic effects in some cases.

For example, formaldehyde, present in many particleboards, is known to be carcinogenic. Similarly, some paints and glues contain solvents that continue to emit toxic fumes long after drying.

The “Airtight House” Effect

With energy efficiency standards, homes and buildings are becoming increasingly airtight. While this helps reduce heat loss, it also has a drawback: indoor pollutants remain trapped. Without adequate ventilation, material emissions can quickly accumulate and reach harmful levels.

This is why, after renovations or new construction, it is essential to ventilate thoroughly for several weeks or even months. It is also recommended to have indoor air quality tested to ensure that no persistent contaminants are endangering the health of occupants.

Towards healthier material choices

Fortunately, the industry is evolving. Today, there are materials certified as low in VOC emissions, eco-friendly paints, natural insulation (hemp wool, cellulose), and solvent-free glues. Certifications such as GREENGUARD, EcoLogo, or LEED can serve as reliable benchmarks when choosing materials.

Making healthier choices doesn’t mean sacrificing design or sustainability. Rather, it’s a way of integrating health into the home from the design stage, an approach that is becoming increasingly important in residential and commercial projects.

The Importance of Environmental Monitoring

At Benjel, we offer a complete indoor air analysis service, including the detection of VOCs, formaldehyde, and other pollutants emitted by materials. Whether it’s after a renovation, a new build, or simply as a precaution, our experts are here to help you understand what you’re breathing—and how to improve it.

Conclusion

Building materials shape much more than our visual environment: they also influence our daily health. By choosing low-emitting materials and monitoring air quality, we create a healthier, safer, and more sustainable environment. With Benjel, you have the tools and expertise to make informed choices.
