The principle behind the ClearComfort window insulation system is to trap a thin layer of air between the glass and the transparent membrane, using the window frame to establish the depth of the air layer. To use the ClearComfort system with frameless glass you will need to attach a supplementary frame to the wall around the glass, or to the edges of the glass itself, or make up removable supplementary frames.

Method 1: Attach a fixed supplementary frame
Use a length of square or rectangular rigid material such as timber or aluminium (eg. 30x20mm or 15x15mm) to make a second frame within the window reveal. Attach the timber/aluminium to the window reveal using glue and small screws or nails. Attach the tape and membrane to the new frame as for a standard window.

Method: 2 Attach a movable supplementary frame

Series of frames side by side

You will need to make up a series of frames (similar to empty picture frames), one frame to match each glass panel. These frames sit abutting each other against the interior face of your existing glass, and can be removable or fixed permanently in place. Attach the tape and membrane to the fabricated frames and you will achieve a sealed air gap between your ClearComfort-faced ‘picture frames’ and the existing frameless glass panels.

Each frame is lightweight and easily made from off-the-shelf components available at hardware stores. We’ve made some using plain 40 x 20mm softwood, which can be painted or left natural, and some using aluminium flyscreen framing, which comes ready-coated in different colours as well as plain aluminium.
