The main suggestion I have for windbreak species is to use a variety, not just one species. You can use a mix of evergreens and deciduous shrubs. I do not suggest using leyland cypress (overused and too many problems). Arborvitae is a better evergreen choice. You can mix in viburnums, clethra, calycanthus and other shrubs to make more diverse and effective windbreak. For instructions on creating a windbreak see this publication.
