Do you, or would you specify timber for external cladding?

At American Hardwood Export Council (AHEC) we are conducting a survey of the external cladding market through the attached questionnaire. The purpose of this exercise is to determine the feasibility of using North American hardwood species for use in external situations, notably cladding. This information will be collated and presented at the AHEC conference in Warsaw in October. Responses will not be disclosed individually and will remain solely within the domain of AHEC.
