Wooden Windows for a Custom Look

While wooden replacement windows are seldom the lowest-cost option, their popularity has held steady for decades. Why?

  • Beautiful and energy efficient – Not only do wood windows look amazing, but wood is a natural insulator leading to less heat transfer
  • Flexible design options – Wood windows come in an almost endless array of designs, colors, shapes, and sizes. You can even opt for between-the-glass blinds, grilles, or shades
  • Insulating Properties – Wood provides 400 times better insulation than steel and 1,800 times better insulation than aluminum-framed windows. It doesn’t conduct heat or cold at all.
  • Longevity – With proper care, wood windows can last a lifetime—that’s why Pella windows come with such an exceptional warranty
  • Coefficient of Expansion (COE) – Every material on earth expands and contracts with extreme temperature shifts. Wooden windows from Pella have the lowest COE on the market. This reduced strain from material expanding and contracting contributes to increased durability and longevity. It also helps prevent the elements from entering your home. The lower the COE of a window, the better.

Alliance Windows Are Premium Vinyl Replacement Windows

Hawthorne Alliance windows provide a well-rounded selection of vinyl options. All their products are designed for maximum energy savings in a fantastic looking package. Their industry-leading warranty is just a pleasant bonus.

Of the Hawthorne styles we offer, the double-hung style replacement windows are among the most popular by far, because they provide:

  • Easy cleaning— With tilt-in cleaning, you can clean the outside from the inside
  • Naturally insulating heavy-walled PVC frames
  • Tight weather stripping and compression seals prevent heat transfer and leaks
  • Energy-efficient ¾-inch insulating glass
  • InnovativE® high-performance glass with a Low E coating that emits low levels of radiant heat
  • Engineered to meet all Madison code requirements

New Windows Make a Statement

New windows with a well-crafted design can also add that little something extra your home is missing.  If you want to make a statement with the architecture of your home, your windows are a powerful tool.

  • Well-sized windows make rooms seem larger without adding floor space or reducing energy efficiency
  • Well-placed windows maximize natural light to create a comfortable ambiance and reduce your need for artificial lighting
  • Well-designed windows provide updated or unique views—nothing’s more impactful than a wall of windows!

At Sims Exterior and Remodeling, we can guarantee your windows will be well-sized, placed, and designed so that your home is not only more energy-efficient, but makes a statement.

We stand behind our work. That’s why we offer a 10-year warranty guaranteeing it. If anything related to workmanship goes wrong, we will fix it.
