In Ukraine, anti-fragmentation ballistic blinds BRONEL have been developed — movable armor panels in a textile cover that are installed in front of windows to protect premises and equipment from fragments during explosions.
The design works on the principle of absorbing kinetic energy: the panel does not repel the impact but dampens the blast wave impulse and stops debris. Inside is a multilayer ballistic package made of non-combustible materials used in body armor. On the outside, it is covered with a cover made of Oxford synthetic fabric, resistant to moisture, mold, and treatment with alcohol- or chlorine-based disinfectants.
As reported by Interfax-Ukraine, the project was launched on October 1, 2026, by representatives of the defense sector, volunteers, and construction industry specialists. According to Artem Genzel, the project's business development director, the developers sought to combine protective materials with interior solutions for residential and commercial premises.
“We do not create illusions of replacing full-fledged shelters, but we provide an opportunity to preserve space and life in a vulnerable moment,” Hensel noted.
The base panel is 80 cm wide, 300 cm high, and 2 cm thick, although the dimensions are custom-made for specific openings. Due to the weight of the ballistic package, the structure is mounted on reinforced anchor cornices with rollers (single-track 40 mm or double-track 80 mm). They are attached to a concrete ceiling or to a wall with the window opening overlapped by 15–20 cm on each side. In normal mode, the panels are slid open, and during an alert they are closed.
According to the developers, the product passed testing at the National University of Defense of Ukraine according to NATO standards and Ukrainian military standards. During the tests, the panel stopped an F5 fragment simulator weighing 1.1 g at a speed of 479.67 m/s. The velocity of glass fragments during an explosion is typically 30–150 m/s.
Developers note that they are focusing on the use of the system in residential buildings, medical facilities, schools, as well as in office centers and data centers. In commercial real estate, the panels are intended to protect workplaces and equipment in the event of destruction of a glass facade. In Tier III and Tier IV data processing centers, the curtains are proposed to be installed on technological windows in the areas
