Sunrooms & curtain wall: aluminum systems

Structural aluminum framing: glazed rooms and full-height facades, engineered per project rather than sized from a catalog.

A sunroom is not a big window; it is a small building. Columns carry roof load, the roof drains through the frame itself, and every joint is a weather detail. That is why these systems are specified by member size and alloy rather than section width.

The German and European style rooms share a 120 × 120 mm column grammar in 3.0 mm titanium-magnesium alloy, in four base forms. The curtain wall system runs an 86 mm sash on a 120 mm reinforced mullion for high-rise and commercial facades.

Inside the frame

The same system, cut open. This is what sits behind the plaster once the trim goes on, and it is where a window succeeds or fails.

The sealing lineA single continuous EPDM strip runs the whole way round. A seal only works where it stays compressed along its entire length, and joins are where they fail.

A window frame edge in section showing the glazing rebate, the desiccant-filled spacer and the gasket — **The glass build-up**Two panes, a sealed cavity and a desiccant-filled spacer, seated in the glazing rebate on its gasket. The cavity does the insulating work, not the glass.

The drainage pathRain that gets past the outer seal collects in the sill chamber and leaves through a channel cut along the base of the profile, instead of running down the face of the window.

Manufacturer-stated for the 120 sunroom system, tested to Chinese GB standards. These are the supplier’s figures, not Nautilus test data.

What a specific opening achieves depends on its size, exposure and installation. That is why we assess the opening before we specify the system.
