Why Replace Your Sliding Glass Patio Door?

Your sliding glass patio door seems to be working fine, so why replace it? In fact, even if your patio door is functioning relatively fine, there may be many benefits to upgrading your home with a newer, more advanced sliding glass door. 

Some of the many reasons to replace old, outdated sliding glass doors include: 

  • Improved Energy-Efficiency: Contemporary sliding glass patio doors possess a number of features to drastically improve their energy-efficiency, including double-paned glass with gas inserted for maximum thermal conductivity, low emissivity coatings, and materials manufactured with the highest insulation ratings on the market: vinyl and fiberglass.
  • Low Maintenance: Modern sliding glass patio doors feature up-to-date technology that reduces the amount of upkeep required. Worn-out rollers, deteriorated weatherstripping, and damaged or misaligned door panels can cause sliding glass doors to prematurely age. The newer materials used in modern sliding doors prevent this—and increase their durability and longevity.
  • Better Safety: New sliding glass patio doors offer a number of features to improve the safety and security of your home. Contemporary sliding glass doors are manufactured specifically with security in mind and include thicker paned glass, state-of-the-art locking mechanisms, and other features to bring you peace of mind—without having to sacrifice on style.

Patio Door FAQs 

What should I look for when buying a patio door? 

There are many things to consider when it comes to finding the right patio doors for your home. You’ll want to look into different materials and how they can affect insulation, energy-efficiency, and even the security of your home. You’ll also want to consider your budgetary needs. Building Envelope Experts offers several cost-effective patio door options that don’t skimp when it comes to quality. Lastly, it’s important to account for the overall design of your home. With a wide range of options to choose from, we can help you find a patio door that suits your unique design aesthetic. 

What type of patio door is most energy-efficient? 

While most modern patio doors are vastly more energy-efficient than their older, outdated predecessors, double-paned glass doors are your best bet when it comes to maximizing the efficiency of your home’s comfort systems. Building Envelope Experts offers several double-paned sliding glass door options from industry leader, ProVia, and we are highly trained and experienced in the installation and replacement of these and all types of patio doors. 

What is the difference between sliding glass doors and French doors? 

Sliding glass doors are installed on tracks, allowing them to slide open and shut from side to side. French doors, on the other hand, have hinges, meaning they open outward onto your patio or into your backyard space. Both sliding glass doors and French doors contain large glass panes, allowing for tons of natural light and a beautiful finish, and both can significantly improve ventilation throughout your home. That being said, sliding glass doors are generally considered to be safer than French doors and are easier to insulate, meaning you may enjoy increased energy-efficiency with traditional sliding glass patio doors. 

Which is Cheaper: Sliders or French Doors?

In general, french doors are cheaper than sliding doors. That being said every project is different depending on size, custom build, and brand so be sure to contact your local patio door installation company for more information. Shall you be local to us, we can assist with sliding glass and French doors installations in St. Louis.

When to Replace Patio Doors 

If your patio doors are obviously damaged—for example, if they won’t slide open easily or if they can’t lock—it’s time for an upgrade. However, it could be time to replace your existing patio doors even without the presence of obvious damage, wear, or tear. So, how can you tell when it’s time to replace your sliding glass patio doors? 

Some signs that you may need to replace your patio doors include:

  • You frequently see condensation, moisture buildup, or fogging between the glass panes 
  • There is a gap between the patio doors and the frame
  • It is difficult to open or shut your sliding glass patio doors/they frequently “stick” 
  • The tracks are misaligned, leading to the doors getting stuck or falling off the track 
  • You notice a draft coming from the doors (a sign of poor insulation)
  • Your energy bills have increased, or you have noticed your heating/cooling system is less effective
  • The rollers and/or frame are damaged 
  • Water pools up or leaks into your home during inclement weather due to damaged weather stripping
