WEST HAMPSTEAD SYNAGOGUE, LONDON
This is an amazing window, with powerful imagery in a kaleidoscope of bright colours.
It measures 3.2m(w) x 4.4m(h) and had been fitted into a new metal frame in 2007. This frame proved to be inadequate in its strength,
and the whole window began to bend to the slightest touch. We were asked to assess the window by John Hoath, of Artemis Conservation.
The concern was that the panels could be blown out in a winter storm, as had been prevalent in recent years. Our job was to remove
the glazing to allow for a new, far more robust metal frame to be installed. This was made by Holdsworth Windows Ltd. of Shipston-on-Stour.
We provided templates of the 9 panels, and they made the frame in a way that prevented as little adjustment to the glazing as possible,
despite the thicker metal sections. The reductions were restricted to the green borders, that were at least 4” wide. These could be
easily reduced without compromising the design.
We completed the work by replacing the perimeter leads, replacing a previously unpainted repair with a painted piece, edge-bonding a
few fire-crazed pieces, cleaning all the glazing and fitting new copper tie wires; sometimes as many as 10 for each glazing bar, as
opposed to the 6 or 7 previously fitted.
We fitted them back using a clear, low-modulus silicon that does not set hard, therefore allowing expansion and contraction of the lead.
