Bacon's Architectural Muntins (BAM!) were designed and manufactured by Bacon & Van Buskirk to meet an architect's need for attractive and durable muntins for a storefront project in Champaign, Illinois. BAM! muntins are aluminum grids that fit over glazing vinyl and have a perimeter anchor flange to resemble old steel sash muntins. They are easy to measure, order, and install compared to traditional storefront muntins. BAM! muntins provide a unique, historical appearance for commercial buildings at a lower cost than true divided lites.
