SAPA 5050 SG

SG - System Glazing

Curtain walling with mini exterior glass holders


The 5050 SG System Glazing facade system consists of 50 mm wide insulated aluminium profiles. The external glass holders are only 32 mm wide, while the internal framework profiles are 50 mm wide. The external glass holders are best installed with countersunk screws, which can be hidden with covers. Rebate for double and tripple glazing units with standard sealing.

The profiles are designed so as to ensure stability under the dimensioning loads. The system can be easily complemented with opening units. The U value of a facade must be reported for the entire facade.
