SEHBAC Windows & Doors Ltd

I had all my windows and back door replaced late summer 2016. The back door is excellent- I have no problems with this and like it very much. My problem is with the windows. I decided to have triple glazing, to help stop the noise from the road. The noise isn't that different. But what is worse is the construct of the windows, the actual glass panels are very small compared to my last windows. The frame is very thick and at the bottom of each window the frame is doubled. This has been done by them laying a strip of frame down on the sill before constructing the actual window frame above it. When I complained that I had lost several square inches of light in each window because the frames are double thickness at the bottom I was fobbed off by them saying they measure the windows from the outside and they were the correct size. My once sunny happy little house is now dark and dreary all year round- I cannot express how much this has upset me, and there appears to be nothing I can do about it. When the salesman came round he actively encouraged me to have extra openings, which I now believe is because the glass is the most expensive part of the installation. I told the salesman at the time that I did not want big frames and that I valued the light in my house. The windows I saw at the showroom did not have this extra strip of frame at the bottom of each. I wish I had never had them done. I am now saving up to have the worst ones replaced individually. I have attached pictures of the bottom part of the frames, the very worst one is the small toilet window- that 'used to' illuminate the stairs and landing. You can clearly see a lot of extra plastic has been used in order to fit a small window.
