first of all any glazing company in your area would be able to do this for you as it is only clear glass with a plastic film over the top to make it blue as blue glass is used for stained glass windows in churches,listed builings ect and would cost a fortune,secondly if its going into a door it needs to be toughned glass under building regulations and last of all you need to mesure opening where glass is going an take 7mm off for clearence both height and width and buy some beading to hold it in.if you want to mail order I would be happy to send you some,I also do bevels and leaded and coloured lights if you want somthing fancy to make your door stand out,you can visit my web site on www.sdwupvcrepair.co.uk if you get stuck or want to order from me,just e-mail through my contact page.hope this helps
