3 Defining Features Of Mi Sliding Vinyl Doors
Mi sliding doors have a number of benefits, but these are the top three features…

Better Performance
Mi doors have quad-seal weather stripping and polyurethane insulation inside the framing to boost energy efficiency. They also have options like warm-edge spacer systems and Low-E glass to achieve even better ratings.
Three Energy Facts About Mi Glass
- All their glass packages meet or exceed Energy Star requirements for our region.
- Their U-factor (heat transfer) numbers are very low – from 0.21 to 0.31.
- Their SHGC (amount of sun UV let in) numbers are also low – from 0.20 to 0.47.
In other words, your new premium vinyl sliding glass door will help keep your home comfortable inside year-round. You’ll also notice lower energy bills and a smooth-running HVAC system.

Lasting, Smooth, Easy Operation
Mi doors are thicker and heavier than standard vinyl sliding glass doors. They’re also designed to sit on a twin-tandem oversized steel rolling system. Both these features combine to give you lasting, smooth operation.
Why Mi Doors Work So Well
- The frame and sash are welded and multi-chambered to increase performance.
- Screens are also top-hung with sturdy tracks to increase ease of operation.
Mi sliding glass doors are quiet and sleek. They move fluidly, and the stronger components LAST rather than wear down or degrade in just a few years.

Improved Home Security
Mi sliding doors are well-known for their added security features. For example, your door can have a concealed three-point locking system that engages with the jamb when closed and locked. This level of security is FAR beyond what you get with a standard sliding glass door.
A Trio Of Security Benefits
- Their doors are tested for water penetration, air leakage, integrity, and forced entry.
- Galvanized steel lock stile reinforcement is used to increase structural strength.
- Thicker framing, locking mechanisms, and stronger components make a STRONG door.
You’ll see why security-conscious homeowners LOVE these heavy-duty vinyl sliding doors as soon as you get to use yours. Will it be impenetrable? No. But it will make your home far safer than a standard door can.

I’d definitely recommend them for quality, timely work….
The Shiner crew provided a prompt response to our request for an estimate, accommodated our schedule to set up the work, and then came at the time promised to do the work. They finished quickly, notwithstanding the horrendously hot weather, and left after providing a detailed description of all they did. I'd definitely recommend them for quality, timely work.
We highly recommend this company !…
We contacted Shiner Exteriors for some major roof and gutter works and are extremely pleased with the entire process. The company is very responsive. Joe Francis visited our home in no time, did a thorough investigation, gave us clear explanations about the issues, and offered several options for renovation and repair. The roof and gutter crews delivered fast, efficient and highly professional work. The teams are extremely dedicated and work together like a very well-oiled machine. It was a pleasure to watch them make progress. We are extremely pleased with the result! Also the clean up afterwards was perfect. Thank you! We highly recommend this company ! Marc Quintyn McLean

We CARE About The Details
Throwing off the family of features you’re looking to enjoy only takes one small mistake. Smooth operation and a tight fit for great energy efficiency are easy examples. Shiner ensures by-the-book installation with perfect measurements and alignment!

Important Sliding Glass Door Replacement FAQs
Am I In Your Service Area?
Shiner Exteriors is based in Sterling, VA. That said, we serve the entire DMV or Suburban Maryland region. You’re likely within reach if you live anywhere in Northern VA–Suburban Maryland. Please visit our Service Areas page for more information. Still unsure? Just call us, and we’ll let you know if we can help.
Am I Restricted To A Small Number Of Colors?
Mi’s sliding glass doors come in ten interior colors that range from Painter’s White to rich Colonial Cherry. There’s also a Raw Pine you can paint or stain. For the exterior, you can choose a custom paint color or a set of about ten neutral tones like Vintage Linen, Royal Brown, or Sandstone.
Are There More Examples Of Your Work?
Sure! Along with doors, we have galleries for roofing, siding, windows, and decking. But that’s not all. You can also visit our Latest Projects page. We use a tracking program called Project Map-It to keep the page updated with our recent projects. Each project includes the service we provided, the products we used, and location data.
Can I Finance My Sliding Door Project?
Commonly, a single vinyl sliding entry door doesn’t require financing. However, when combined with other projects like new windows, it can help you budget. A great payment plan can also help you get the upgrades now rather than waiting until the whole lump sum is in your account. Visit our Financing page for more info.
How Long Will My Sliding Door Installation Take?
If all we’re doing is installing a sliding glass door, it’ll just take a few hours. Remember, our crews are experienced and specialized, so they have the process and procedures down to a science. On the other hand, if the door is part of a more extensive, more complex exterior remodel, your project timeline will be well-scheduled and explained in detail before we get started.
How Long Will My Vinyl Sliding Door Last?
When properly cared for and cleaned, you can expect to enjoy your thicker, heavier Mi vinyl sliding door for at least four to five decades (see warranty info in the next question). But what’s nice is the steel roller system and upper screen track are just as durable. These aren’t doors that break down or are hard to use after just a few years. No way!
What Hardware Finishes Does Mi Offer?
The hardware for their Sunrise Series of sliding glass doors comes in basic White, Brushed Nickel (gray), Forever Finish Brass (gold), Antique Brass (light brown), or Oil Rubbed Bronze (darker). Including trim options, these colors go well with almost any door system.
What Kind Of Warranty Protection Does Mi Provide?
Mi provides comprehensive coverage through an industry-leading Lifetime Non-Prorated Transferable warranty. What does it cover? Just about everything—corner welding, frame, sashes, hardware, glass, etc. If you’d like more info, please contact our office. During your initial meeting, your Shiner project consultant will also walk you through the details.

Why Not Wood Or Aluminum Sliding Doors?
Nothing is objectively wrong with a wood or aluminum sliding glass door. It comes down to pricing, durability, and maintenance. Vinyl offers great durability without the higher maintenance of wood or aluminum. It is also resistant to warping, rotting, and corrosion, making it ideal for our Northern VA–Suburban Maryland area.
