Why choose patio doors built by the nation's leading window manufacturer?
Because patio doors take a lot punishment from installation to daily usage to the burning sun and freezing rain. But through it all, Andersen ® patio doors retain their beauty and durability. All our doors feature the high quality craftsmanship and materials that make our windows so efficient -- and so popular. Our products are designed to work together to create a cohesive look outside and in. It's no surprise, then, that Andersen Corporation is also the leading manufacturer of patio doors.
