* The manufacturer states Uw = 0.8 W/(m²K) for a 2700 × 2300 mm structure with T4 + 18 Swisspacer Ultimate + FL4 + 18 Swisspacer Ultimate + T4 glazing. Actual Uw depends on whole-construction dimensions, glazing, spacer and specification. System weight and size limits require confirmation for the layout; they are not guarantees for every order. The family's reference Uw does not apply automatically to every MB-70 and MB-70HI specification; confirm the selected variant.

Questions about MB-70 / MB-70HI PSK
Does 0.8 W/(m²K) apply to both variants?
The family page gives a reference value. It cannot automatically be applied to every MB-70 and MB-70HI specification; confirm the actual variant.
Is it the same as an MB-70HI exterior entrance door?
The profiles are related, but PSK uses different operation and hardware. Patio PSK and hinged exterior-door data must be assessed separately.
