wooden wedges spacers

Good morrning,

Is it possible to use spruce wood wedges to insert a wooden door frame made of softwood into a brick wall opening for FD 30?

Yes it is. If you are using softwood (redwood or whitewood) for the door frame you can use the same materials for the packers / folding-wedges. But obviously, hardwood or hardwood plywood is more resistant to compression.
