Marvin Coastline Collection Discontinuation

11/3/25

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 High Velocity Hurricane Zone (HVHZ) or Impact Zone 4 (IZ4) regions. This includes the discontinuation of HVHZ/IZ4 solutions offered in Marvin’s Ultimate product collection:

• Ultimate Casement window 

• Ultimate Awning window 

• Ultimate Direct Glaze window 

• Ultimate Swinging French door 

Marvin will continue to offer Impact Zone 3 (IZ3) products that meet the needs of the vast majority of coastal impact regions.
