Before diving into the details, let’s briefly introduce these two patio door brands.

Reliabilt is a house brand owned by Lowe’s that offers vinyl, aluminum, wood, and fiberglass patio doors at affordable price points.

They aim to provide quality patio doors to budget-conscious DIYers and homeowners.

Reliabilt products can only be purchased at Lowe’s stores or on

Pella is a long-standing, premium window and door brand sold through exclusive dealers across North America. Unlike Reliabilt, Pella specializes in upscale wood, fiberglass and vinyl patio doors with high-end features and top warranties.

They are known for exceptional quality, performance, and aesthetics.

Now that you understand the overall vibe of each brand, let’s explore how Reliabilt and Pella patio doors compare across several important factors:

Patio Door Frame Materials Comparison of Reliabilt And Pella Patio Doors

One of the biggest differences between Reliabilt and Pella is the materials used for the patio door frames and sashes. This impacts the overall durability, functionality and cost.

  • Reliabilt vinyl patio doors feature heavy-duty vinyl extrusion frames and sashes. While dependable, the vinyl formulas are more basic compared to premium brands.
  • Pella uses their proprietary vinyl formulations for enhanced durability and longevity. Their premium vinyl resists fading, pitting, and warping.


  • Both Reliabilt and Pella offer fiberglass patio doors praised for their strength, low-maintenance, and resistance to temperature fluctuations.
  • Pella fiberglass doors feature thicker, denser fiberglass construction compared to Reliabilt’s standard fiberglass.


  • Reliabilt only uses basic pine wood species, which is knotty and prone to swelling/shrinking. Their wood doors are among the lowest cost options.
  • Pella handcrafts their wood doors from clear premium pine, oak, and other luxury hardwoods selected for beauty and performance.


  • One material option only offered by Reliabilt is affordable aluminum-framed patio doors. But aluminum is prone to denting and has high conductance.
  • Pella does not offer aluminum patio doors, likely because it is considered a lower-end metal with subpar insulation properties.

In summary, Pella invests in top-tier materials across all their patio door product lines, while Reliabilt uses good yet more basic, budget-friendly materials.

Energy Efficiency and Temperature Performance Comparison

Energy efficient patio doors are important for keeping your home comfortable and reducing energy bills. Here is how Reliabilt and Pella patio doors compare when it comes to thermal performance:


  • Pella offers high-performance Low-E coated, argon gas filled double or triple pane glass. This provides excellent insulation with solar heat control.
  • Reliabilt patio doors come standard with basic clear, double pane glass. Triple pane is an upgrade option, but still lower quality than Pella.


  • Both brands use weatherstripping around the door panels to seal out drafts. However, Pella tends to use thicker, higher grade weatherstripping for a tighter seal.
  • Reliabilt weatherstripping meets minimum standards to keep air and water out, but it is not as heavy duty or long-lasting.


  • Pella patio door frames are engineered with innovative designs and structural enhancements for top thermal performance.
  • Reliabilt door frames meet basic insulation standards but lack Pella’s advanced construction.


  • Top end Pella patio doors can meet stringent ENERGY STAR Most Efficient performance criteria.
  • Reliabilt patio doors typically achieve only the minimum qualifications for basic ENERGY STAR certification.

In summary, Pella patio doors are decidedly more energy efficient. Their U-Factors can be as low as 0.17 compared 0.30 for Reliabilt. But Reliabilt still provides good energy savings on a budget.

Patio Door Styles and Configurations Comparison

When it comes to patio door styles and configurations, Reliabilt and Pella have plenty of options in common along with a few key differences:

In summary, while Reliabilt and Pella both offer all the most common patio door configurations, Pella provides far more aesthetic customization possibilities for a luxury look and feel.
