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.
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.
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.
