Hello
I am going to build a glass roof that has a width between 312 and 317cm.
The length is 450cm.
I would prefer to have them with 4 sections, which results in glass sections between 75-76cm; they will need some gap on the beams for fittings, etc. I already have the glass figured out; these will likely be 6mm or at most 8mm.
I have considered using glued laminated beams of 56x225 to have long beams along the length without a joint in the middle; it's okay to joint them in 2-3 places if required.
The inner length will be screwed to the facade, and the outer length will rest on 3 pillars with 1.5 meters in between each.
I checked what they can handle, and it states they can take 0.4 kn/m2, which I calculate to be 40kg/m2 (is that correct?)
From what I've gathered, the glass weighs between 15-20kg/m2 depending on thickness.
Living in southern Skåne, snow is not something I need to worry too much about.
Does anyone have good knowledge about the load-bearing capacity of glued laminated timber or any other input to provide?

What can support a load of 0.4 kN/sqm? It works well to use glulam 56x225 as roof beams. At the front, they should be attached to a glulam load-bearing beam resting on posts with a 1.5 m distance. It is sufficient to use 42 mm glulam for the load-bearing beam. It looks best if this is also 225 mm high.
0.4 kN/sqm is approximately the same as 40 kg/sqm, that is correct. However, there must have been some misunderstanding since the beam's load capacity is entirely dependent on its span.
I have already checked that 56x225 is sufficient for the roof beams. I just didn't understand where 0.4 kN/sqm came from. But now I do.
