01
The detail
Hardware you feel before you see
Brushed multi-point furniture on a reinforced leaf. Every lever throws into a steel keep before the door moves an inch.
Premium windows, doors & panels
French Doors
Double leaves. Unbroken elegance.
Two leaves swing apart from a slim meeting stile, leaving the whole opening clear. Multi-point locking on both.
02
The movement
Eighty degrees of clear opening
Three hinges carry the weight. The swing stays true after tens of thousands of cycles, in heat and in frost.
03
The result
A doorway, not a door
Slim sightlines, a thermally broken threshold, and a sealed unit that keeps the weather where it belongs.

One handle, two actions. Tilt in from the top for secure trickle ventilation, or turn the handle again to swing the whole sash inward for cleaning.

Testimonials
Trusted across the Kathmandu valley
Homeowners and architects in Nepal, in their own words.
The tilt-and-turn windows cut the Ring Road noise. Rooms stay warmer through winter, and the team finished the whole house in a week.
We specified anthracite for a shopfront in Patan. Hi-Tech matched the sample, and the frames went in on the date we agreed.
The sliding doors open onto the garden without a fight. Through a full monsoon they have not swollen or stuck once.
