Details
MB-79N Pro is our everyday recommendation when a project wants a clean, contemporary aluminum sightline at a more accessible price point than our premium Reynaers lines. The 6-chamber, 74mm frame keeps sharp, minimalist edges while still delivering U-factors as low as 0.15 Btu/h·ft²·°F and up to 47 dB of sound reduction.
The system is available in casement, tilt-turn, and hidden-sash configurations, so it adapts to whatever opening style a room calls for, and an optional attachable nailing fin simplifies new-construction installs. It’s the aluminum equivalent of our Kombisystem uPVC line — proven, versatile, and built for volume.
