AluK SC156TT

AluK SC156TT is a thermally broken lift-and-slide door for wide openings, with a slim central interlock, concealed locks and a low-threshold option. In the UAE it suits villa living rooms onto the pool, penthouse terraces and high-floor balconies: sashes weigh 300/400 kg, glazing goes up to 50 mm, and watertightness is classed E1500.

Technical data

Thermally broken lift-and-slide door system for wide openings, with a slim central interlock, concealed locks and a low-threshold option.

Values are the manufacturer's published figures for the series; the actual value depends on the configuration — glass, size and hardware. Which series fits your opening is settled at the free survey.

Lift-and-slide means the handle raises the sash off its seals to move it and lowers it back to close. We fabricate AluK profiles to the manufacturer's specification in our Dubai factory and install them ourselves.

Wide openings onto terraces and pools

The system is made for the openings that shape a villa: a living room that opens onto the garden, a majlis onto a courtyard, a penthouse onto a roof terrace. Once lifted, a heavy sash moves on rollers, so a large pane can still be pushed by hand, and the concealed locks keep the frame clean when it is shut.

What the figures mean in UAE weather

Watertightness class E1500 is the figure to note for high floors and exposed coastal plots, where storm rain is driven sideways by the wind. When lowered, the sash sits on its gaskets, which is also what keeps fine dust out after a shamal. With triple glazing the published Uw is 0.9 W/m²K, and the glazing pocket of up to 50 mm also takes a double-glazed solar-control unit with laminated panes for a sun-facing elevation.

The low-threshold option removes the step between the room and the terrace. It still needs a drained channel outside, which we plan together with the terrace floor.

SC156TT, SC140TT or INFINEO S146LM

SC140TT is the broader AluK sliding system: 140 mm deep, sliding or lift-and-slide on two or three tracks, sashes up to 2500 × 2800 mm and 400 kg, glazing up to 40 mm, with a motor as an option. INFINEO S146LM hides the frame and narrows the interlock to 21 or 31 mm, with sashes up to 3000 × 3000 mm and 450 kg but glazing only up to 32 mm. SC156TT sits between them: thicker glass than either, a 50 mm interlock and a published E1500 watertightness.

SC156TT is the AluK choice for a wide, heavy glass door that has to stay tight against wind, rain and sand.

The honest downside

Where SC156TT is not the right sliding door

The central interlock is 50 mm wide. For a view where every line of frame counts, INFINEO S146LM with its 21 or 31 mm interlock and hidden frame gives a cleaner picture, as long as its 32 mm glazing limit is acceptable.

Lift-and-slide is also more system than a small balcony needs. For a standard apartment balcony door a plain sliding door on SC140TT is simpler to operate and to service.

Consider instead AluK INFINEO S146LM

Frequently asked questions

Its watertightness is classed E1500. On site the result also depends on the sill detail, the drainage and the fixing into the slab, so at the survey we check the exposure of the elevation and the wind load for the height.

There is a low-threshold option. We design it together with the terrace floor and a drainage channel outside, so water and sand have somewhere to go instead of collecting at the sash.
