I bought two sheets of 2mm polycarbonate sheets for two Victorian windows as secondary glazing. They were take the price of anywhere else so payback time is halved! I bought them online for collection at Bidder St but the system somehow ended up in Main branch in Kent. After an immediate phone call the sheets were sent to Bidder St and I got an email to confirm their arrival (ahead of schedule) so I made up cardboard protectors cut to the window size (and bungees) and made my way from Lewisham via the DLR. On arrival the desk guy was very friendly and offered to cut the sheets (as I would have done on the floor using the cardboard templates). This saved me a lot of time and Stanley knife effort! Thanks! It was only one 750mm cut. I wrapped up the more manageable sheets with the offcuts and made my way back no problem via the dlr with my valuable cargo. They fitted perfectly in the window frames and now our kitchen has many less draughts and is decidedly warmer! Thanks again! Mike This has always been my goto place for years to secondary glaze all my house windows.
