1. Introduction
1.1 Application, effect, function
 Application:
Connecting balcony slabs, beams, projecting parapets, other projecting
construction elements as well as full storey-high projecting walls
 Effect:
Thermal separation avoids condensation and the formation of moulds; it
also reduces heat losses and its associated CO2 emissions
 Function:
Thermally separated reinforcement system for connecting detached
reinforced concrete components to the building

1. Introduction
1.2 State of technology
 According to recent technical standards, the junctions between balconies
and buildings have to be thermally separated. The intention is to interrupt
the flow of heat from the inside to the outside. This is achieved by inserting
insulation between the two components.
“…thermally separated
construction should be used…”

4.4 Sound insulation
With balconies and access balconies, vibration is transferred into the main
structure of the building and distributed into adjacent rooms as airborne sound.
DIN 4109 specifies the maximum level of airborne sound pressure level, which
penetrates to the adjacent units of the building and which is measured with a
standardized tapping machine.
erf. L´n,W = 53 dB
The standard versions of HALFEN HIT insulated connections can fulfill the
sound insulation requirements for balconies.

Basis: laboratory tests
From laboratory measurements, the difference
in the impact sound pressure level ΔL was
examined on a balcony slab made with units in
comparison to a continuous
floor slab.
