Some benefits of buying tempered glass deck railing panels include safety, durability, resistance to the elements and the fact that they also provide an unobstructed view of outdoor surroundings. Although it is a glass product, tempered glass is different from normal glass because it is shatter-resistant, notes the Decks.com. This is because tempered glass is quite strong due to the process used for its manufacture. Additionally, if tempered glass does shatter, it does not break into dangerous shards that can cause an injury.
Other advantages of using this product for deck railings are that it tolerates heat and resists corrosion. Unlike a wood deck railing that can crack under moderate heat, tempered glass does not crack. Similarly, when exposed to water and other weather conditions over long periods of time, this type of railing material does not wear down like wood.
When compared to wood railings, tempered glass may not require as much care and maintenance as wood, states One Day Glass. However, like normal glass, tempered glass does require regular cleaning.
Although tempered glass can be useful for deck railings, it can have a few disadvantages, such as it is very expensive and presents certain privacy issues. For example, neighbors can look through clear tempered glass. To avoid this problem, there are tinted and frosted tempered glass products for deck railing.
