Absorption
Absorption and thus weakening of energy rays as they pass through matter. Absorption is the third determining quantity, in addition to transmission and reflection, in the passage of rays through glass.
Transmission + Reflection + Absorption = 100 %
The radiation energy is converted into heat energy by absorption. This leads to an increase in temperature of the absorbing pane of glass.
Alarm Glass
TSG or LSG combined with various security systems such as alarm wire or alarm strip burnt into a sheet of TSG. Alarm TSG is a single-pane security glass with a burnt-in conducting strip that is interrupted when the pane is destroyed, thus triggering an alarm. The TSG alarm pane must be positioned facing the side exposed to attack.
Annual Primary Energy Requirement
The introduction of the new verification quantity "annual primary energy requirement" in the current German EnEV allows the planner to design the building shell of a new building in accordance with his creative ideas. He is free to choose the individual building materials for the different subsections and is no longer bound by the U-value specifications.
Verification of the annual primary energy requirement is carried out in accordance with the currently valid EnEV. The exact window sizes must be taken into account for the producing of the energy balance.
Anti-Vandal Glazing
The A class of anti-vandal glass defined in part A of DIN EN 356 is divided into five groups with increasing protective effectiveness. The testing procedure assumes a heavy missile, which is simulated with a 4110 g metal ball with a diameter of 10 cm in free fall. The ball is dropped onto each test piece (110 cm x 90 cm) three times from the same height.
There are four dropping heights, depending on the load type, which define the resistance class. In the group P1A the glass unit must withstand the ball dropping three times from a height of 1.5 m, in group P2A from 3.0 m, in group P3A from 6.0 m, in group P4A the dropping height is 9.0 m, and for group P5A the test piece must withstand this dropping height nine times.
Attack-Resistant Glazing
Divided into the groups:
test standard
PxA = anti-vandal glazing DIN EN 356 A
PxB = penetration-resistant glazing DIN EN 356 B
BR = bullet-resistant glazing DIN EN 1063
D = explosion-resistant glazing DIN 52290
