Hello
I am working on a new project which will be a sunroom connected to a deck I built two years ago. The deck is supported by steel piles to the bedrock and on these are HEA100 steel beams (or 2x45x220 - 1.9m from the house). For the foundation of the sunroom, I plan to use glulam (315x115). The glulam beam on the side runs from the girder in the house's foundation wall/concrete beam to a steel beam on the outer edge (3.4m). On the outer edge, I have a third glulam beam that runs between the side beams. This beam will partially sit on the steel beam (50:50). But the question is how best to join the glulam at the corners (see images)?
Long wood screws (Essve Construction Screw ET-T 8.2x245) or sturdy brackets on the inside? However, I'm having trouble finding sufficiently sturdy brackets (Simpson AG922 or Simpson CLT ABR 255?). Maybe I should have the local blacksmith make sturdier brackets at 120x120x120 in 5mm steel.
The glulam beams (which I received from a colleague) will be painted and clad with metal for weather protection. The floor will be tiled and insulated with electric underfloor heating embedded in reinforced (steel mesh) self-leveling compound. The rest of the build will be in glulam with "winter-insulated" glass sections and an insulated roof with metal on the outside (see image).
Any tips or ideas?
Best regards,

I built the entire sunroom with ET-T screws.

If you use ET-T, make sure to drive the screws at an angle so the screw passes through multiple growth rings, see the screw's user manual.

Do not completely cover glulam beams with sheet metal, they will rot. Here in town there was a roof over a gas station, they placed advertising signs directly against glulam beams and after 10 years a corner fell down, full of mold under the metal. However, certain surfaces exposed to rain can be protected.
No, no. There will only be metal on the outside with a drip edge at the bottom so that water and snow on the deck, as well as sunlight, do not affect the glulam. Then there will be a small air gap between the metal and the wood.L Leif i Skåne said:Do not cover glulam beams completely with metal, they will rot.
