Premium windows & doors
Marvin®
HB Siding installs Marvin windows and doors for homeowners who want thoughtful design, durable materials, and a broad range of options. Family-owned and founded in 1912 in Warroad, Minnesota, Marvin brings a long history of craftsmanship to new and replacement projects.
Marvin offers material choices for different priorities. Signature Ultimate offers natural wood interiors with extruded-aluminum-clad exterior options. Elevate combines warm wood interiors with Ultrex® fiberglass exteriors. Essential uses Ultrex fiberglass on both the interior and exterior for a streamlined, low-maintenance option. Other Signature lines use different material systems.
Ultrex is Marvin’s proprietary pultruded fiberglass. Marvin states that it is eight times stronger than vinyl and three times stronger than vinyl/wood composites. It expands and contracts at nearly the same rate as glass, a characteristic that helps resist leaks, seal failures, and stress cracks. Its acrylic finish is designed to resist fading, chalking, and peeling.
