Cupolas are used as vents for heat and moisture. All cupolas can be custom-fabricated with any design into a windowed or louvered frame. A family crest or the first letter of last name can be incorporated into your design as well. Contact us with the details of what you have in mind and we will do our best to accommodate you. Lead-time on all cupolas is at least 2 weeks, unless we have what you need in stock already. Any of the SMW finials can be attached to our cupolas.
