Facade The stadium's
façade refers to the Polish national colors, resembling a waving
flag of Poland and it consists of silver and red colors. The same palette was used to color the stadium's seating. The facade which consists of painted mesh that was imported from Spain, covers the inner aluminum and glass elevation. The stadium is an open structure, which means the lack of a closed facade, so the temperature inside is similar to the environmental temperature, despite the closed roof construction. Such a construction allows for natural ventilation of rooms placed under the stands and access to natural light. '' standard stadium seats, type: FCB in red and silver colors Elevations are stretched on pipes that were manufactured in Italy. This structure is completely independent from the concrete stand construction, and it is fundamental to the retractable stadium's roof. Thanks to this, designers could freely design the space under the stands.
The pitch The stadium is equipped with a heated pitch. The pitch is installed with a lawn of Dutch grass, cultivated in
Heythuysen, the Netherlands. During the organization of events such as concerts, the pitch will be covered with special panel, which must be removed within 5 days of its installation. A second option: to install a grass field on a special floating platform, was discarded due to it being too expensive.
The grandstands The National Stadium was designed by the German-Polish consortium gmp Architects von Gerkan, Marg and Partners, J.S.K Architekci Sp. z o.o. and sbp—schlaich bergermann und partner (the design by Volkwin Marg and Hubert Nienhoff with Markus Pfisterer, Zbigniew Pszczulny, Mariusz Rutz, Marcin Chruslinski). The structure is composed of two-level stands—top and bottom—with a capacity for 58,580 spectators. All seating in the National Stadium was provided by Polish company Forum Seating (part of the
Nowy Styl Group located in
Krosno). There are 900 seats for media and press, more than 4,600 so-called "premium seats", designed for special guests, 106 seats for disabled people and more than 800 seats in the VIP lodges. during the process of opening Under the stands, there are changing rooms, conference halls and living areas with a total area of . The building has eight stories with varied heights. The highest point at the stands, is located above the former 10th-Anniversary Stadium pitch, while the highest point of the steel roof structure is above that level. The roof can cover not only the stands, but also the pitch.
Retractable roof Partially transparent, the retractable roof was made of fibreglass covered with
teflon. This kind of material is resistant to weather factors (rain, the heat of the sun, and can hold up to of wet snow) and the crease tendency. The production technology comes from German company Hightex GmbH, and the textile was produced in Bangkok by the Asia Membrane Co. Ltd. The process of opening or closing the roof takes about 20 minutes and it can only be performed at temperatures above and not during rain (this was the reason for a one-day postponement of the football match against England on 16 October 2012). A drive system is used for stretching the
membrane during the process of opening and for folding the material during the process of closing the roof. The total weight of the steel-cables supporting the roof structure is . Under the roof, there are four
LED display screens, each with an area of . ==Construction history==
