MB-70HI takes the standard MB-70 profile and adds high-insulation (HI) thermal break technology — improved polyamide separation between inner and outer aluminium chambers. 70 mm depth keeps the sightlines slim, while Uw 1.1 W/m²K meets typical residential thermal codes.
Frame integrity warranted for 25 years. Surface finish warranty 15 years. Drutex/Aluprof manufacturing standards.

Why undefined?
MB-70HI sits between the deeper SI-series (86N, 79N) and the standard MB-70 — the right choice when the project needs aluminium aesthetics, slim 70 mm sightlines, and code-compliant thermal performance. Best for renovations of older aluminium-clad buildings where matching the original profile depth matters.
