Switch off for windows in brick wall?

[Haegermeister]

I will install a window in my basement wall made of concrete blocks, the problem is that the window is 275cm wide (60cm high), i.e., I need to support the sill beam of the house above the window. I plan to go down one block height (19cm) from the sill.

Question: How can I do this the easiest and cheapest way? Someone suggested a glulam beam that is screwed under the sill... and then plastered from the outside... I'm grateful for more suggestions on solutions and maybe someone has a good idea of how sturdy a beam would be needed?!

Glued laminated timber beam seems to be an expensive option. If I were you, I would install an I-beam instead. This gives the entire structure a lower building height compared to glued laminated timber beam. But most importantly, the construction will withstand weather and wind better. This should be the easiest and cheapest way. The price of the beam can be given to you by a blacksmith.

To calculate the size of the beam, you must know what the house looks like, that is, how much vertical load the beam must bear. One or two, three floors and the construction of the exterior wall to determine the weight that will load the beam.

PS. Maybe it could even work with a concrete beam, it all depends on the vertical load.

(Never plaster, NEVER plaster a load-bearing structure of glued laminated timber into the foundation of the basement.)

Glulam beam seems to become an expensive story. If I were you, I would mount an I-beam instead. This gives the entire construction a lower building height compared to Glulam beam.

The house is 1 1-/2 storeys...can’t you just go for a 180mm I-beam?

Is it OK to cast/render the I-beam into the wall?

Hmmm. I'll see what I can do. I'll check some of my old books and maybe do a quick calculation on the bending moment that might occur in the I-beam. I'll get back to you.

Hmm how's it going with the calculations :-/
