Maroon Watcher Posted August 10, 2014 Share Posted August 10, 2014 My extension has a big hole for a Skylight. What glass do I need - as people will walk around it on the 2nd floor. I was told that even with safety glass I would have to have 10cm2 (4" X 4") metal frame under the glass... defeats the object Any ideas? Link to comment Share on other sites More sharing options...
trogers Posted August 10, 2014 Share Posted August 10, 2014 I think you misunderstood about the metal. They are talking about a holding frame, and not a plate. Similar to a window frame. What kind of roof cover are you using and what is the size of the opening? Link to comment Share on other sites More sharing options...
Maroon Watcher Posted August 10, 2014 Author Share Posted August 10, 2014 It's a flat concrete roof that will form part of a smaller 2nd floor building - meaning the 1.2 m X 2m skylight would form part of the roof terrace on the next floor Visitors could stand right next to it - hence the saftey aspect. I have thought of building a small fence around it But that would probably/should be 1m high. Perhaps balustrades.. I would prefer just to have glass perhaps in the shape of an angled, all glass "cold frame" (4 small sides and a top, with a vent) - again, if this was flat and strong enough to walk on, it would be too expensive? The whole idea is to see the stars from our sofa, and increased light in the day I think you misunderstood about the metal. They are talking about a holding frame, and not a plate.

wayned Posted August 10, 2014 Share Posted August 10, 2014 For safety you should use at least 1": tempered glass. There was a recent thread in the pet forum where someone built a giant fish tank using it. You should search the forum and PM him. 1 Link to comment Share on other sites More sharing options...
trogers Posted August 10, 2014 Share Posted August 10, 2014 There should be a raised concrete curb of at least 20cm height all round the roof opening to sit your skylight. The concrete roof waterproof system should be turned up to cover the face of this curb. The shape and profile of the skylight can be discussed with the contractor. Given the small opening size, a window contractor can handle the job. Link to comment Share on other sites More sharing options...
