The ideal double glazing solution for protected structures and conservation areas

The combination of a narrow gas space between the panes and a narrow seal around the edge means that the comfort and thermal efficiency of double glazing can be brought to Period buildings in conservation areas.

Ultra slim double glazing units

These very slim double glazing units rely on heavy inert gases to reduce the thickness of the units to 11 or 12 mm (½”) while retaining a reasonable thermal value of U = 1.4, using Xenon gas and U = 1.9, using Krypton gas.

You can find further technical information here.When replacing single glazing with the very thin double glazing, we may need to rout out some timber from the glazing bar(s) and the sash rails, in order to make room for the slimpane units.
