5 Requirements in terms of building physics

5. Requirements in terms of building physics

 

 

Thermal insulation and moisture protection

The requirements of the current Energy Conservation Ordinance as well as DIN 4108 must be observed. Thermal bridges are to be avoided. Non-transparent infills (panels) in windows and window walls are governed by the requirements for lightweight external walls. The stipulated thermal conductivity group is indicated separately in the performance specification. The construction details shall limit the effects of driving rain and condensate sufficiently to avoid damage (e.g. the impermissible reduction in thermal insulation).

 

The position and arrangement of vapour barriers and membranes must correspond to the state of the art and comply with the system manufacturer´s instructions. Any structural joints shall be manufactured such that they are impervious to air and moisture and are vapour-tight on the inside.

 

Sound insulation

In consideration of DIN 4109 - sound insulation in buildings, the aluminium constructions offered for tender must provide the sound insulation stipulated in the performance specification. Proof shall be provided in accordance with DIN 4109 or via a prototype test.

 

The floor and/or parapet, ceiling and partition wall joints as well as the joints between the elements and the type of glazing shall be carefully designed and executed in order to achieve the best possible sound insulation and to reduce any flanking transmission.

 

Larger sheet metal areas such as curtain wall sheeting or window sills shall be equipped with a sound-deadening coating. In accordance with DIN 18360, number 3.1.5.11, the thickness of sound-deadening coatings must be at least 2 mm.

 

Fire protection

Structural fire protection requirements corresponding to the provincial building regulations as well as any additional provisions laid down by the authorising bodies shall be taken into account (high rise buildings, department stores, places of congregation, etc.). Any requirements pertaining to building components, materials and anchorages in the parapet area must be observed in terms of fire behaviour pursuant to DIN 4102.
