When considering how much of a gap should be under a fence or gate, a good rule of thumb is to keep gaps between 2 and 5 inches tall. This allows for some ground clearance for the gate but still provides safety for children and pets, who shouldn’t be able to squeeze through a gap of that size.

There is no best color for a vinyl fence, as it truly depends on a homeowner’s aesthetic preference. Classic white is the most popular and widely available of all the vinyl fence colors. However, contemporary black, warm browns, and natural grays are becoming more mainstream. One perk of darker-colored fences is that they are easier to “keep clean,” as in, dirt and debris don’t show up as easily as they would on lighter-colored fences. So if you don’t plan to give your fence regular washings, a dark color like black, gray, or brown would be the best choice.

The thickness of a glass fence varies widely based on its application and whether or not there are any safety requirements, but most fences are between 8 millimeters and 12 millimeters thick. 12-millimeter-thick glass is extremely strong and overkill in most cases, which is why you typically only see it around pools and in skyscrapers.

Glass has one of the longest lifespans of any fencing materials, lasting anywhere from 10 to 30 years on average. Just how long your glass fence lasts depends on several factors, including how well you maintain your fence, the climate, and the type of glass you use. 

If you live somewhere with severe weather like hail, tornadoes, or hurricanes, expect your glass to have a shorter lifespan. Pool glass is one of the thickest tempered glass materials and may last longer than other options—especially compared to laminated glass.
