Electrically heated glass has recently been installed at Artis. This heated glass remains free of condensation, ensuring an optimal view and allowing visitors to enjoy the lions from a minimal distance. The glass assembly consists of 30mm-thick, anti-reflective, low-iron, laminated safety glass. Combining various functions—such as anti-condensation and anti-reflective properties—while ensuring the glass is strong and secure enough to withstand the impact from the lions, is the specialty of Thomsa Glass.
