The entrance area of a building gives visitors an important first impression. This is particularly true of the entrance to Covestro’s new campus office building in Leverkusen, where employees and visitors feel immediately welcomed in the large, bright atrium.
One special attention-grabber is the decorative flooring. It consists of a polyurethane (PU)-bonded rubber granulate terrazzo and is sealed with an aqueous 2-component coating based on the company’s PU coating raw materials. The coating system is more environmentally compatible than conventional systems, also aesthetically pleasing and it meets typical building requirements for impact sound insulation and walking comfort.
“Especially in buildings with high foot traffic, it’s important to have an abrasion-resistant and durable flooring so that it still looks appealing after several years,” explains Contardo Pafumi, Industrial Marketing Manager Construction at Covestro. “For such applications, polyurethane-based sealers have proven their worth. They are very robust and also easy to clean.”
More environmentally compliant coating
For these and other reasons, Covestro chose the elastic terrazzo system from the Swiss installation company TEXOLIT AG. It is also particularly low in emissions and complies with AgBB regulations for indoor air emissions. It is also suitable for environmental certification under the LEED Gold Standard (Leadership in Energy & Environmental Design).
In total, an area of 1800 square meters was equipped with the terrazzo floor. The coating comes from coatings manufacturer KLB Kötztal Lacke + Beschichtungen GmbH and is based on an aqueous polyacrylate dispersion from Covestro´s Bayhydrol® range and a polyisocyanate crosslinker from the Bayhydur® series.
