As of November 3, 2025, the Marvin Coastline product collection has been discontinued, and the SIW Solutions retail operation in Delray Beach, Florida, is now closed. 

With this discontinuation, Marvin will no longer manufacture products for Impact Zone 4 (IZ4) regions. This includes the discontinuation of IZ4 solutions offered in Marvin’s Ultimate product collection:

Marvin will continue to offer IZ3 products that meet the needs of the vast majority of coastal impact regions.
