Listed Building Double Glazing Units
Glazing for Period and Conservation Area Properties
Timbalite conservation glazing units are manufactured using a combination of the very highest specification materials available.
As standard, our slimline glazing units include Softcoat 1.1 glass as its Low E pane, which is more thermally efficient than traditional hardcoated glass, such as K glass, and it also does not carry the same amount of colour.

With Timbalite conservation glazing units being available with either a 4mm or 6mm cavity, they are available from only 11mm thick with a perimeter seal width of from only 7mm.
This enables period property homeowners to benefit enormously from energy efficient, listed building double glazing, whilst replicating the original design of their listed windows, including the narrow glazing bars so important to maintaining a truly authentic appearance.
Example of conservation glazing detail:
12mm Timbalite slimline glazing unit
Sightline / Seal Depth
11mm / 12mm unit with 4mm cavity: 7mm sightline (+1mm tolerance)
13mm / 14mm unit with 6mm cavity: 8mm sightline (+1mm tolerance)
Units can be installed to both new and restored traditional listed windows and doors with putty line detailing to match the existing.
These high performance conservation glazing units are produced using the latest technology warm edge spacer bars in a choice of colours, ensuring they are as thermally efficient as possible and can produce centre pane U values of 1.9 or 1.5 Wm2K on a 4mm gas filled cavity, to as low as 1.4 or 1.2 Wm2K on a 6mm gas filled cavity, depending upon the type of gas fill used.
