TRC Windows commissioned for the extensive renovation

In April 2019, TRC Windows was commissioned to deliver the supply of windows throughout this extensive renovation. Over a 14-month period, and completed in 2020, a total of 338 metal, 140 timber and 110 new heritage timber sash windows were successfully reinstated.

Metal windows

In line with the project scope, metal frames and casements were stripped of paint and rust.

Weld repairs were carried out to areas of damage, with new hinges and new sections of steel used where required.

A five-coat Teamac Painting System was used on all frames.

New 4mm GoetheGlas* heritage glass was installed, with applied lead work replicating the original glazing layout.

Timber windows

The timber window repairs were subject to overall draughtproofing and redecoration. These were painted using a Dulux Paint System, and installed with new 4mm GoetheGlas heritage glass.

Heritage box sash windows

Constructed from hardwood timber, the heritage windows incorporate single-glazing with a 4mm GoetheGlas heritage glass, and work via a classic weight-and-pulley mechanism. These also include individual solid bars providing the windows with genuine character. Traditional heritage putty was used externally to secure the glazing and enhance the visual aesthetic.

*GoetheGlas is a colourless, drawn glass with the irregular surface characteristic of window glass common to the 18th and 19th centuries. It is used to protect precious, leaded glazing from the elements and other adverse environmental conditions.
