Thin Double Glazing

About Thin Double Glazing

We make it possible to install beautiful double-glazing in your historic property without ruining its appearance or even replacing the windows!

The benefits

Now you can fit double-glazing to period windows, even into narrow original rebates. Beautiful aesthetics, great insulation – and usually a better chance of planning permission.

HD10

Our ultra-slim Thin Double Glazing units measure just 10mm from inner to outer pane, offering the ultimate solution in replacement glazing for conservation areas.

Table of options

The table of options will help you to choose the right replacement glazing for your period property, according to the size of your rebates and your planning requirements.

HD11

At only 11mm thick, our HD11 Thin Double Glazing is ideal for restoring the windows in historic properties. Like all our double glazing, it complies with every part of BS EN 1279.

HD12

Our HD12 unit is just 12mm thick, and will be selected according to the size of your rebate. As with all our Thin Double Glazing, it carries a 7-year manufacturer’s warranty.

HD13 & HD13/1.3

HD13 & HD13/1.3, both measuring 13mm thick, both offer exceptional thermal insulation (with U values at 1.5 and 1.3 respectively) plus noise reduction certified at 34dB.
