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
This handy table will help you choose the right units for your project, according to factors such as thickness, spacer-bar size, rebate size, energy savings and acoustic levels.
D13 & D13/1.3
D13 & D13/1.3, 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.
