The gap between the two panes must be around 12mm, and it's important to fill the gap with Argon gas for optimum thermal performance. A larger gap can be used to lower the noise level, but it will lower the insulating performance of windows.

Once the frame has been cleaned it is a good idea to spray it with window cleaner prior to fitting the DGP.
