Key Differences Between Pella And Wallside Windows

Here we’ll break down how major factors like materials, efficiency, styles, cost, and warranties weigh up between Pella and Wallside.

Window Materials

One of the biggest differences between these brands is the material options available.


Pella offers windows in:

  • Wood – Oak, pine, alder, and maple. Their patented wood composite resists shrinking and swelling.
  • Vinyl – Heavy-duty, low-maintenance, and energy efficient. Offered in a variety of colors.
  • Fiberglass – Durability and insulation of wood with low maintenance. Won’t warp or crack.

They have a leg up over Wallside when it comes to material choices. Wood and fiberglass give Pella products added beauty and strength.


Wallside windows only come in:

  • Vinyl – Durable, energy efficient, and affordable. Available in white or beige.

While vinyl performs well and is low maintenance, it lacks the elegance and customization of Pella’s selection. Wallside’s color choices are also more limited.

Overall, Pella offers superior material options like fiberglass and real wood veneers. Wallside’s sole vinyl offering gets the job done but is less customizable.

Energy Efficiency

Both brands meet or exceed ENERGY STAR qualifications. However, there are some differences when you dig into the nitty-gritty details.


  • U-factors as low as 0.17 on Impervia fiberglass models with triple pane glass.
  • Optional triple pane glass for improved insulation.
  • Foam insulation injected into frame and sash on Impervia line.
  • Optional argon/krypton gas filled windows.
  • Optional Low-E (low emissivity) glass coatings to reduce heat transfer.


  • U-factors around 0.27 with double pane glass.
  • Triple pane models offered for colder climates.
  • Silicon injected into frame for insulation.
  • Low-E coatings standard.
  • Optional argon gas filled glass.

Both brands offer impressive technology like triple glazing and Low-E coatings. But Pella eeks out the win with even lower U-factors down to 0.17 and more standard features like foam-filled frames.

The verdict: Pella windows perform slightly better overall from an energy efficiency standpoint. Wallside still offers thermal improvements over builder-grade windows.

Window Styles

Pella and Wallside both carry a wide selection of styles. Here’s how they compare:

In terms of affordability, Wallside is the clear winner. You’ll easily spend $200+ more per window with Pella. Of course, the higher cost comes from premium materials and features.

For affordability, Wallside windows provide better value. Pella offers luxury if budget isn’t a concern.


The warranty coverage is actually very similar between Pella and Wallside.

  • 20-year glass warranty – Insulated glass unit failures.

Both brands offer long-term assurances against window defects. Pella extends the lifetime warranty to cover exterior aluminum cladding as well.

For most homeowners, the two warranties are virtually identical. We’ll call warranties a tie between Pella and Wallside.
