New Windows with Names Your Can Rely On

In the Sims collection there’s a window for every design – double-hung, unique sliders, casement windows or something special. There are sizes, shapes and colors to enhance your home inside and out. The two most popular choices for window materials are wood and vinyl. Sims is certified to sell, install and maintain some of the best-known brands of each – Pella Wooden Windows and Alliance Hawthorne Vinyl Windows.

Pella Wooden Replacement Windows

This lineup of American-made wooden windows has represented innovation in technology, manufacturing skills and quality for decades. The Pella Corporation has more than 150 product and design patents.

Pella window quality is tested and proven. In extensive lab testing, windows are evaluated for –

  • Exposure to extreme temperatures – with infrared cameras detecting energy loss
  • Accelerated weathering – extremes of wind and elements
  • Acid/salt corrosion
  • Specially designed light chambers simulate direct sunlight – ultraviolet, visible light and infrared
  • Advanced testing of wood preservatives to ensure resistance to moisture, decay, stains, mold and mildew

Sims features the Pella 450 Series of wood replacement windows. It combines the beauty of wood with low-maintenance technology. The new windows of the 450 Series are energy efficient and adapted to most any requirement. Highlights of the Pella 450 Series include –

  • Wooden interiors Pella will stain, paint or prime prior to installation
  • Low-maintenance, aluminum-clad exteriors are available in 10 colors
  • EnduraClad® protective finish resists fading
  • EnduraGuard® wood protection resists moisture, decay and stains – as well as termite damage
  • High-transparency screens
  • A wide range of standard styles, shapes and sizes
  • Made-to-order replacement windows are available
  • Limited Lifetime warranty
  • InsulShield® energy-efficient glass collection
  • Exceed Energy Star guidelines 

Wood Replacement Windows – For A Custom Look

Wooden replacement windows are rarely the low-cost option but are popular for many reasons, including –

  • Beauty and Comfort – Wood is not only beautiful, it’s a natural insulator
  • Design Flexibility – Wood provides multiple design options – including interior and exterior colors, shapes, sizes and between-the-glass blinds, shades and grilles
  • Insulating Properties – Wood is an excellent insulator because it doesn’t conduct heat or cold. Research shows wood provides as much as 400 times better insulation than steel and more than 1,800 times more than aluminum-framed windows.
  • Wooden Windows Last – With appropriate care, wood will last a lifetime – hence the exceptional warranty offered on all Pella windows
  • Coefficient of Expansion (COE) – All materials expand and contract with extremes in outdoor temperature. Pella wooden windows have the lowest COE compared to common window options. The amount a material expands/contracts contributes to its stability, wear and ability to keep the elements out of a building. The lower the COE the better.

Sims provides several Pella options including –

  • Pella 450 Series – The most popular style, offering the best features of wooden windows – the most sought-after styles, shapes, sizes, features and options.
  • The Architect Series – Available in both a traditional line and a contemporary line, these wooden windows offer unique sizes and shapes. Options include Low-E triple pane glass for high energy efficiency.
  • The Designer Series – Unique features and options include between-the-glass blinds, shades and grilles.
