Bullet-proof Security Windows in Wood and Wood-Aluminum According to DIN EN 1522
To protect life and limb from the deadly threat of firearms, we recommend in addition to a high resistance class (RC), the furnishing of your wood or wood-aluminum elements with additional bullet resistance. Frame, glazing and fittings thus become a security barrier without weak points, which optimally secures you against assailants.
Throughout Europe, the bullet-resistance classes FB1 to FB7 are defined according to DIN EN 1522. These classes indicate the resistance to attacks with firearms of different calibers. We offer products up to FB6 (attack by shotgun caliber 7.62 x 51), thus a very high protection standard. It is essential to choose the glass in the quality NS (not splintering). As glass splinters resulting from the bombardment with a firearm, can be as deadly for the inhabitants as the weapon itself.
In a ballistics test, a German test laboratory checks whether the window or door as an overall construction can withstand the fire of a certain type of weapon.
The projectile of a .44 Remington Magnum is already inhibited in the FB4 class. In the ballistics test of this class, the test element is fired at from a distance of 5 meters at 42 previously marked points with this calibre. The full metal jacket bullets hit the frame, connection and glazing (safety glass BR4NS) at an average speed of 450 m/sec. The firing angle varies between 45 and 90°.
Bullet and Burglary Resistance Certified protection for life and limb
We offer our customers certified burglar-resistant security elements in cat. RC2 to RC4 made of wood and wood-aluminum in combination with bullet-resistance FB4 to FB6 (attack by shotgun caliber 7.62 x 51) and thus a very high standard.
Our safety products combine optimum mechanical safety for your home with today's common standards for thermal insulation, sound insulation and, if desired, fire protection.

Your questions – our answers
Are security windows or window-doors difficult to operate?
These elements are actually much heavier than standard products. The glass alone weighs many times more! That is why we install suitable high-performance fittings precisely matching to the weight and ensuring good and easy handling.
