Creating a Virtually Frameless Glass Railing for a Balcony

An old college friend of mine wanted to add a bit of drama to a very narrow house in Southern California. Since it was a townhouse, they didn’t have room for a big deck or porch. Instead, they wanted to build a small balcony to create a spot to enjoy the skyline and relax at night. They ran into a roadblock when the building inspector told them that in order to do this, they’d have to build a fairly high railing. They immediately worried about the railing blocking the view – undermining their original intention for the space. They needed a railing that would comply with codes but would also deliver on their vision. That’s when they started to consider glass.

Glass railings work well with a view for one obvious reason: you can see right through them. Perfect, right? But while glass might seem like a no-brainer, there are a couple of hang-ups that often prevent people from committing. The first is the idea that they’ll be hard to keep clean. But despite your vision of smudges and handprints, glass isn’t as hard to clean as you might think. The second is often fear of installation – since working with large panels of fragile glass might be intimidating. The good news is that you have lots of good options when it comes to ease-of-installation, so long as you know what you’re looking for.  Just keep a few basics in mind, and you’ll be able to add a beautiful, no-fuss railing for your balcony that offers a minimum of obstruction while also being safe and secure.

Adding a Glass Railing to a Balcony

With a balcony, you’re often working with a limited or narrow space. If that’s the case, you’re going to need a customizable glass railing set up that can work in limited space. The options are extensive but can be broken down into two style categories. You can use can use a full glass railing custom cut to fit your specific measurements, or you can use a kit designed to be easy to install that allows you to drop glass panes or balusters into a specially-designed railing system. Regardless of which you choose, you’re going to need the following:

  • Tempered glass: The last thing you want is glass that shatters if something hits it. Tempered glass is designed to withstand an impact. This is particularly important with a balcony, since you’re often dealing with high winds and the possibility that tree branches, or even birds, will run into the glass.
  • Hardware: The hardware you use needs to be specifically designed to work with glass, and it should be long-lasting and corrosion-resistant, like stainless steel. The glass part of your railing will last for years, so you want your hardware to last just as well.
  • Ease of installation: Glass railing isn’t something you can typically install yourself, unless you choose a manufacturer that makes kits with precut panels and a drop-in system. This is the best way to DIY your glass railing Otherwise, you’ll need to choose a system from a company that will send an expert to your home to install it for you.

While you’ve probably seen the completely frameless glass railings advertised, I’ve found that this style usually ends up being a tricky and frustrating project for the homeowner, requiring careful measuring of the glass and ultimately bringing a professional in to install it. For some people, a glass railing without a top rail can also feel unsafe. For all these reasons, I generally suggest a glass panel railing system with posts and both top and bottom rails. It opens the view while providing a sense of security and provides easy installation.

Considerations When Working With Glass Railings

When working on a balcony, a big consideration is whether your glass railing meets the minimum height requirement. The height requirement for balconies follows the height requirements for most decks and porches, in that railings must be at least 36 inches high. Specific to working with glass, you should remember:

  • There’s a no margin of error for glass measurements: If you’re using glass cut to your specifications, keep in mind you’re going to have very little leeway with those measurements. If your numbers aren’t exact, you could wind up with unusable panels. And if those panels were custom cut, you're not going to be able to return them. While the general rule is to ‘measure twice, cut once,’ in this case, you want to measure twice and then have someone else verify those measurements to avoid making an expensive mistake.
  • Keep the 200-pound load weight in mind: On balconies, it’s generally required that the railing be able to hold a minimum of 200 pounds of pressure. Glass tends to have a lower load weight than other materials, so make sure the glass you buy can work under that level of pressure. This shouldn’t be an issue if you’re buying glass that’s meant for railings, as a railing manufacturer will make sure their glass meets the basic standards for railings.
  • Be considerate of the nature around you: If you live in an area with a lot of birds, like a forest or a more rural area, you’ll need to accept it’s possible that animals will run into the glass if you don’t find a way to keep them from flying too closely. One common way I’ve seen it done is to add realistic-looking owl figures to the balcony to scare away smaller birds. Tinted glass also helps with this, as does placing stickers on the glass. You may also have an easier time keeping birds from flying into the glass if your railings have a top and bottom rail, instead of adhering to the completely frameless style.

After a lot of hemming and hawing, my college friend and his wife finally went with a railing system from the company I usually recommend, Fortress Building Products. Their glass railing system isn’t totally frameless--it still has a top and bottom rail with traditional-looking aluminum posts in between the glass panels--but it completely changes the view and feel of their little townhouse balcony, while still framing the area and fitting in with the traditional style of their home.

I can’t stress enough that when it comes to installing glass railings, you need to work with a company that takes care in the design of the railing system so that it’s safe to use and easy to buy and install. I’ve found that the Fortress® Pure View glass railing provides everything you need while minimizing the fuss and risk in installing glass railings. I’ve depended on Fortress’ full range of products for other projects as well; they make well-designed, durable, and high-quality products that also add style to any application you use them for.
