Superglaze is a 2 part secondary glazing system which can be used with 3 or 4mm plastic or glass sheet. The base section provides rigid capping for the sheet edges, and also a channel through which it is screwed onto the window surround. A cover section clips into this channel to hide the screws and complete a very smart appearance, particularly as the strips can all be mitred for neat corners. The insulation provided by Superglaze is effective for both heat retention and external noise reduction.
Installation is straightforward, using normal household tools, and is covered in the video above, or full instructions can be printed from the PDF on this page. The mitre bead supplied slots into the capping before cutting the mitres, and the whole system can be removed if required.
Where a window surround is not flat or has rough surfaces, Superglaze can be installed with a simple foam draught excluder stuck to the underside before screwing into place, which will even out undulations and create the thermal seal necessary for effective heat and noise insulation. Superglaze can be used externally as well as internally, and can be unscrewed and stored during the summer if required, before being re-attached for the next winter.
