Restoring Orosi Windows

The orosi, a vertical sliding sash with timber girih lattice and coloured glass, is one of the most delicate elements of the Iranian house.

As found

Of the seven orosi in the Kashan house, only two were intact. The rest had broken glass and missing timber pieces.

A master orosi maker from Isfahan numbered each piece, dismantled, cleaned and reassembled it. Missing parts were made from reclaimed plane wood.

Improving performance

To improve thermal performance, a discreet layer of clear glazing was added behind the sashes, invisible from outside.

Today coloured light falls once more across the carpets of the summer room.
