I got a tour of their factory and got to actually see my windows being made and how the large sheets of glass are cut by the machines. They did my house very recently and I couldnt be happier with the quality and the price.I went for cream windows and black georgian 6 panel insulated front door. I went for tripple glazed and also had custom hand made stained glass fitted in the porch too.Hand cut and laid stained glass panel which is then fitted inside 2 panes of glass for the porch windows.Not that cheap stick on stained/lead effect stuff.

We just got french doors fitted from TSL Windows in Tallaght. We got 3 quotes from different companies prior to this and they were the best price… They also have their own factory (mentioned on another boards.ie thread), which means they can do non standard sizes. They arrived first thing 9am, and were very professional. I have no connection, just a happy customer who thinks good companies should get credit where credit is due, especially these days.
