When it comes to product lines, Andersen® windows and doors offer unprecedented value and customization. Perhaps that’s the reason Andersen® is the largest window and door manufacturer in North America. Andersen® was founded in 1903 and is privately owned. The company is known for its strong history of commitment to its business partners, employees, community, and environmental stewardship.
For Brennan customers, Andersen® offers true variety. Their 100 Series Fibrex Windows and 400 Series Wood Windows deliver cost-efficiency and craftsmanship. The A-Series Fiberglass Clad Windows promise the fine details and accuracy of architectural styling, while the E Series Aluminum Clad Windows offer complete customization in sizing, style, and design — you name it. There’s a reason Andersen® is among the top-selling products for Brennan customers.
Looking for a weathertight window that also allows you to get the most from a nice breeze? Choose a casement window. The casement window's seal meets the sash straight on for a weathertight seal. This is Andersen's most energy-efficient casement window.
