Trend ekologické výstavby: střechy, které čistí ovzduší Trend of ecological construction: roofs that clean the air

The ECO-ACTIV bituminous membranes from Icopal Vedag CZ contribute actively not only to improving air quality but also to human health. This innovative waterproofing material for flat roofs is based on the principle of autocatalysis, which removes harmful substances from the surrounding environment.

ECO-ACTIV bituminous membranes represent a building material with a great future. They find applications mainly in large urban agglomerations and near traffic arteries with a high concentration of nitrogen oxides (NO_X) in the air. These harmful substances penetrate the lower respiratory tract and cause health problems for children, sensitive individuals, and people suffering from asthma.

On the principle of autocatalysis

One of the ways to effectively remove nitrogen oxides from the air is to utilize the principle of autocatalysis. This principle has penetrated into many fields of human activity in recent years, whether in healthcare, the automotive industry, or urban construction.

The BMI Icopal brand has also taken advantage of the positive impact of the autocatalysis principle on the environment and developed the bituminous membrane ECO-ACTIV, which significantly reduces the concentration of nitrogen oxides in the air thanks to its patented NOXITE technology.

Patented NOXITE technology

This unique waterproofing membrane is independently protected by NOXITE material (part of the top layer), which contains titanium dioxide (TiO₂), an element with autocatalytic properties. Together with UV radiation, it transforms nitrogen oxides into by-products that are washed off the roof during rainfall. According to laboratory measurements, the quality of the runoff water is not adversely affected by these by-products. The resulting effect of pollution removal is permanent throughout the lifespan of the bituminous membrane.

High-quality execution

The ECO-ACTIV bituminous membrane stands out not only for its unique air-cleaning technology. Other advantages that insulation professionals and property owners appreciate include the longitudinal and transverse joint of the membrane without granulate for reliable welding (END LAP) and a factory-trimmed corner (T-CUT) that reduces the risk of capillarity at the so-called T-joint. The proverbial cherry on top is the white granulate on the top side of the membrane, which is interesting both from an architectural and a technical standpoint (preventing overheating of the membrane).

If you are looking for a modern roofing waterproofing solution with excellent technical parameters, innovative features, and a positive impact on the environment, then ECO-ACTIV bituminous membranes are the right choice for you. For more information, visit the website icopal.cz.
