Best Patio Doors For Cold Weather: Energy-Efficient Options Compared

When the temperature lowers, and winter arrives, your patio doors are more than just an access point to the great outdoors—they’re vital to keeping the indoors warm and the energy bills low. Best Offer Glass understands the importance of investing in the correct type of patio doors if you reside in an area with cold, wintry weather. With the proper energy-efficient doors, you can take in the view of the winter wonderland without losing heat or running up your heating bill.

In this guide, we’ll take a look at the best patio doors for cold weather, review top recommendations, and discuss what it takes to make a patio door energy-efficient.

Why Energy Efficiency Matters in Cold Weather?

Infiltration of cold air and heat loss through poorly insulated doors can be a significant source of energy waste. The U.S. Department of Energy says doors and windows account for as much as 30% of heating and cooling energy consumption. During winter, that translates to higher bills and chilly drafts.

To fight back, the best patio doors for cold weather provide:

• Superior insulation
• Low-emissivity (Low-E) glass
• Weatherstripping and tight seals
• Strong frames that withstand temperature changes

Let’s compare the top options and materials on the market today.

1. Sliding Glass Doors with Low-E Glass

Sliding glass doors are a popular choice for patios due to their sleek look and space efficiency. However, not all are created equal. For cold climates, it’s essential to choose models with:

• Double or triple-pane glass
• Argon or krypton gas fills.
• Low-E glass coatings deflect heat inward in winter.

Advantages:

• Smooth operation
• Maximize natural light
• Insulated glass tight seals

Disadvantages:

• It may be less airtight than hinged doors if seals weaken over time.

Our Recommendation: Choose ENERGY STAR qualified sliding doors with composite or vinyl frames for greater insulation.

2. French Patio Doors (Inswing or Outswing)

French doors consist of two hinged panels that open from the middle. They provide a classic look and function well with large openings. The most effective cold-climate models have insulated cores and energy-efficient glass.

Advantages:

• Solid, secure shut
• Can be equipped with double- or triple-pane glass
• It can be made to blend in with traditional or classic home architecture.

Disadvantages:

• It needs more clearance space than sliders.
• Heavier, affecting ease of use if not installed correctly

Energy Tip: Go for fibreglass or wood-clad frames with thermal breaks and tight-sealing weatherstripping for optimal energy performance.

3. Folding (Bi-Fold) Patio Doors

Folding doors, such as accordion or bi-fold doors, are becoming the star for their flexibility and spacious opening width. In winter climates, use thermally broken frames and insulated glass to enhance energy efficiency.

Pros:

• Makes wide openings when desired
• Upscale appearance
• It can be set to open partially or entirely.

Cons:

• Generally more costly
• Needs skilled installation to seal in freezing weather properly
• Cold Climate Consideration:

Select models with multi-point locking systems and composite thermal breaks to stop drafts and energy loss.

4. Lift-and-Slide Patio Doors

Lift-and-slide doors have a mechanism that raises the door panel slightly before it slides open, forming an ultra-tight seal when closed. This makes them a high-end choice for very cold or windy climates.

Pros:

• Top air and water sealing
• It is ideal for large glass panels with no energy loss.
• Smooth and easy operation

Cons:

• Higher upfront cost
• Installation must be precise for optimal performance.

Best Offer Glass Pro Tip: Invest in uPVC or fibreglass frames and triple-pane glass for the best cold-weather thermal performance.

What To Consider In A Patio Door For Cold Weather?

1. ENERGY STAR® Certification

Always purchase doors that comply with ENERGY STAR requirements for your climate zone.

2. U-Factor

Defining how well a door resists heat loss. The lower the value for winter climates, the better. Choose U-factors of less than 0.30.

3. Solar Heat Gain Coefficient (SHGC)

The amount of solar heat allowed to pass through the glass. For colder climates, a greater SHGC (approximately 0.40–0.55) is desirable to permit passive heating from sunlight.

4. Gas Fills

Argon or krypton gas between panes of glass substantially enhances insulation.

5. Low-E Coatings

Reflects infrared heat into your home while letting visible light in.

6. Weatherstripping

Several layers of high-quality weatherstripping prevent drafts.
