Folding doors: aluminum systems | Nautilus Philippines

Multi-panel systems that concertina and stack aside, opening up to 90% of the wall instead of half of it.

A sliding door always keeps one panel’s width of glass in the opening. A folding door does not: panels hinge against each other and stack at one end, so almost the entire opening clears.

The trade is hardware. Every hinge line is a sealing line and a load path, which is why the range runs from the light NF-01 at 50 kg a sash to the structural NF-04: 145 mm section, 3.0 mm profile, 120 kg a sash.

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.

Aluminum profiles in section showing the polyamide thermal-break strips between the inner and outer chambers — **The thermal break**The blue strips are polyamide, threaded through the profile to hold the inner and outer halves apart so heat and condensation cannot bridge the metal.

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.

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.

Performance

Rated by the supplier for up to 90% clear opening; the heavy sections are stated for entrance doors on large villas and commercial buildings.

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