Well you could create your own IsAlpha. I would extend the version you found to at least include spaces and periods.
something like this might help you along.
declare @ScalarVal varchar(100) = '123.'
select case when @ScalarVal not like '%[^a-z0-9 .]%' then 1 else 0 end as IsAlpha
You could turn that into a function if you wanted.
