I have a table for sizing the beam required to span a wall to be removed. one of the criteria is type of masonry? dense masonry, medium masonry and lightweight masonry. For the type of load the beam is going to carry. The wall to be supported by the steel beam is Thermolite 4inch plastered on both sides I Think it would be classified as medium density ....Any body out there know for sure??? The span is 2.5 metres and no floor is carried on this wall.
