Patio doors offer beauty, light, and easy access to outdoor spaces—but they’re also a prime spot for energy loss if they’re not sealed properly. Whether you’re dealing with drafts, water leaks, or higher energy bills, upgrading your weatherstripping can make a major difference.
In this guide, we’ll walk you through the best weatherstripping options for patio doors, help you choose the right one for your home, and show you how this small upgrade can have a big impact—especially if you own a Glenbrook Patio Door. Let’s dive in.
Why Weatherstripping Matters for Patio Doors
Your patio door may look secure, but even a tiny gap between the frame and the door can let in cold air, moisture, insects, and more. Weatherstripping helps close those gaps, keeping your home:
- Comfortable – no more cold spots in winter or heat waves in summer
- Energy-efficient – lowers heating and cooling costs
- Protected – keeps dust, debris, and pests out
- Quiet – reduces outdoor noise from entering
If you own a Glenbrook Patio Door, you already have a high-quality entry point to your backyard. But even the best doors need maintenance, and weatherstripping is one of the most important parts to keep in top shape.
Types of Patio Doors and Why They Matter
Before we jump into specific weatherstripping materials, it’s helpful to know what type of patio door you have. This will determine the kind of seal you need.
1. Sliding Patio Doors
These doors operate on a track and move horizontally. Because they don’t close as tightly as hinged doors, they’re more prone to air leaks.
2. French or Hinged Patio Doors
These swing open like regular doors. They usually seal better than sliders but still need quality weatherstripping along the bottom and sides.
3. Glenbrook Patio Door Systems
Glenbrook offers both sliding and hinged styles, known for their durability and insulation. Still, even these premium doors can benefit from updated weatherstripping—especially in older models or high-use areas.
Best Weatherstripping Materials for Patio Doors
Let’s explore the top materials used for sealing patio doors. Each has its own strengths depending on your door type, climate, and usage.
1. Foam Tape Weatherstripping
Best for: Gaps on the door frame or sliding doors
Material: Open-cell or closed-cell foam with adhesive backing
Foam tape is one of the easiest DIY weatherstripping solutions. Just cut to size and stick it where needed—usually along the vertical frame of sliding doors or on the sides of French doors.
Pros:
- Affordable and easy to install
- Great for moderate gaps (⅛” to ½”)
- Works well with Glenbrook Patio Doors, especially around fixed panels
Cons:
- Can wear down faster in high-traffic areas
- Not the most durable for heavy weather exposure
2. Felt Weatherstripping
Best for: Temporary solutions or low-traffic doors
Material: Plain felt or reinforced with metal/plastic
Felt is another budget-friendly option. It’s great for blocking drafts but doesn’t hold up well to water or heavy use.
Pros:
- Cheap and easy to install
- Flexible and soft
Cons:
- Short lifespan
- Not great for outdoor or wet conditions
- Not ideal for high-end Glenbrook Patio Doors
3. Vinyl or Rubber Door Sweeps
Best for: The bottom of swinging patio doors
Material: Flexible rubber, silicone, or vinyl
A door sweep attaches to the bottom of your patio door, sealing the gap where air, water, and insects love to sneak in.
Pros:
- Excellent for keeping out water and bugs
- Durable and long-lasting
- Ideal for Glenbrook’s hinged patio doors
Cons:
- Slightly harder to install (may require screws)
- Adds some resistance to door movement
4. Brush-Style Weatherstripping (Pile Weatherstripping)
Best for: Sliding patio doors
Material: Dense synthetic fibers
This type of weatherstripping uses tightly packed bristles to create a flexible seal without restricting movement.
Pros:
- Great for moving parts like sliding doors
- Long-lasting and low maintenance
- Works well with Glenbrook sliding systems
Cons:
- Less effective at blocking moisture
- Doesn’t provide a thermal seal as tight as rubber
5. Compression Seals
Best for: French patio doors
Material: Rubber or silicone
Compression weatherstripping is designed to compress when the door closes, forming a tight seal that blocks air and moisture.
Pros:
- Excellent air and water seal
- Durable and reliable
- High-performance for Glenbrook Patio Doors in cold climates
Cons:
- Requires precise fit
- May be harder to install without professional help
How to Choose the Right Weatherstripping for Your Patio Door
Here are a few things to consider when choosing the best option for your home:
1. Door Type
Sliding doors need low-friction materials (like brush seals or foam), while hinged doors work best with compression seals and door sweeps.
2. Gap Size
Measure the width of the gap between the door and the frame. Foam tape works well for small gaps, while larger gaps may require a combination of sweep and compression seals.
3. Climate
If you live in an area with cold winters or heavy rains, go for heavy-duty options like rubber seals or compression weatherstripping.
4. Aesthetic Compatibility
For a premium look—especially with Glenbrook Patio Doors—choose a discreet seal that blends in with the design.
Weatherstripping Maintenance Tips
Even the best weatherstripping needs upkeep. Here are a few quick maintenance tips to extend its life and performance:
- Clean it regularly with mild soap and water
- Inspect for wear or gaps every season
- Replace as needed, typically every 1-3 years
- Lubricate sliding tracks to reduce friction and prevent tearing of seals
With proper maintenance, your weatherstripping can last for years and continue to protect your investment in Glenbrook Patio Doors.
DIY Installation vs. Hiring a Pro
Many types of weatherstripping are DIY-friendly—especially foam tape and brush seals. But for high-end Glenbrook systems or if you’re dealing with complex door mechanics, hiring a pro may be worth the investment.
DIY is ideal if you:
- Have basic tools and skills
- Are sealing small gaps or replacing old seals
Hire a pro if you:
- Have a custom Glenbrook door
- Need airtight insulation for extreme climates
- Want a perfect finish with zero guesswork
Boosting Value with a Simple Upgrade
Weatherstripping might seem like a minor detail, but it plays a huge role in your home’s overall energy performance. When properly sealed, your Glenbrook Patio Door:
- Enhances your home’s value
- Reduces energy costs
- Prevents long-term damage from water or insects
- Increases indoor comfort all year round
It’s one of the most cost-effective upgrades homeowners can make—and it pays off in both short-term comfort and long-term savings.
