A hinged sash closes against the frame on all four sides, which is why it suits rooms that are cooled around the clock. TB-600 does that job with a profile extruded here in Dubai by Gulfex (Gulf Extrusion LLC). We fabricate it to the manufacturer's specification in our Dubai factory and install it ourselves.
Where TB-600 windows belong
Villas, townhouses and apartments where the opening is a window rather than a wall of glass: bedrooms, studies, kitchens, stair landings. The series takes side-hung casement sashes and tilt-and-turn sashes, so a bedroom can air on the tilt at night while the living room next to it opens fully for cleaning.
The same family makes the TB-600 hinged doors on the same 60 mm frame and the same 18–38 mm glazing range. On one elevation the windows and the terrace door can then share sightlines, finish and glass build-up.
What the figures do in UAE heat
The 18.6 mm polyamide strip is the thermal break. It holds the outer aluminium shell, which sits in the sun, apart from the inner shell facing the cooled room, so heat has no direct metal path inwards and the inner face of the frame stays warmer. In a humid coastal summer that is the difference between a dry frame and water on the sill.
Gulfex publishes a thermal transmittance k of 3.0 W/m²K and does not say whether it is a frame (Uf) or whole-window (Uw) value, so we do not set it against the Uw figures of other series. The published duty rating is H-HC40. On a high floor or an exposed seafront elevation, the wind-load calculation for the building sets the sash sizes.
TB-600 or TB 62
TB 62 is the other hinged series from the same house: a 62 mm tubular frame, a 70.5 mm sash and a wider 22.0 mm polyamide strip, with the same published k of 3.0 W/m²K. Its glazing range is narrower, 24–28 mm. TB-600 is the one to choose when the glass has to be thinner or thicker than a standard double-glazed unit, for example a laminated acoustic build-up on the side facing a road.
For the window openings of a villa or apartment TB-600 is a sound, locally extruded hinged series; for a wall of glass, look at the sliding ranges.
