While this may seem absurd, the cost of the frame and its glass is lower that if the glass was cut by a glazier (who would have to work also the edges to make them not too sharp). Choose the white not anti-glare glass!

Swisspor Pur Alu insulation Board. The Panel consists of a synthetic foam with aluminium foil glued on both sides . Other polyurethane insulation panels sold in DIY shops can be used instead (e.g. polyfoam in Jumbo, 8.95 Frs for a board of 1.20 x 62 cm). In this case, place a metal sheet on top of the board (ideally copper) to transfer the heat to the tube and also avoid the paint to 'melt' the synthetic foam.
