The lifting and sliding SL 1600tt system intended for structures with strict thermal insulation requirements.
In PLUS variant, the heat penetration coefficient UF is from 2,1 W/m2K, whereas in the warmest variant – HI – the heat penetration coefficient Uf is from 1,8 W/m2K.
The design depth of the sections is 67mm for wings, and 160mm with regard to two-row frames, and 247mm with respect to three-row frames. The structure of the profiles allows manufacturing stable large-size structures, even 6-wing structures, whose wings are very heavy.
In the system it is possible to use 50mm-thick fillings.
