Andersen uses only the finest wood and checks its millwork for the most precise craftsmanship. But it’s not just the exactness, it’s also their aesthetics. It might be more accurate to compare Andersen® products with fine furniture than other windows.
LOW MAINTENANCE EXTERIORS
Available in White, Sandtone, Terratone® or Forest Green colors, their exclusive Perma-Shield® cladding protects the window’s exterior beautifully and eliminates the need for painting or repainting. The cladding surrounds solid wood cores which make Andersen® windows far more reliable and durable.
TIGHT, RELIABLE SEAL
Andersen® windows and patio doors seal shut to the tightest tolerances in the industry, minimizing drafts, dust, and water infiltration. Their closure and thermal performance help make them some of the world’s most energy-efficient windows.
Andersen stands by its products, and the people who use them. Their limited warranty is one of the most reliable product certifications available. 20 years on glass. 10 years on non-glass parts. The coverage is non-prorated and fully transferable, so it can add real value should you decide to sell your home.
