Oknoplast is the first producer of PVC frames to use the innovative material Aerogel. Applied by NASA for the construction of spacecraft, the heat shields of shuttles and protection in spacesuits, Aerogel is an excellent insulator, easy to work and very strong. The technicians of the company have developed a unique, patented system for the application of Aerogel to PVC frames of the latest generation, like the Winergetic Premium Passive in class A Gold, also suitable for passive constructions, and able to further optimize their performance. The patented design of the Winergetic Premium Passive section with Aerogel, marked by light, minimal lines on the inside, sinuous and rounded lines on the outside, is enhanced by the use of the exclusive Design + hardware created by the Austrian design studio Kiska.
