Railing systems are becoming varied and intricate. One specific type we are seeing more and more is the glass rail. Glass deck railing systems are unique deck products that promise to add a modern flare to deck and patio design ideas for decks in Virginia, DC, and Maryland. Their visual appeal and durability, courtesy of glass railings and stainless steel balusters or glass balusters, are not matched by many other porch railings, including cable deck rails. However, so-called invisible railings for decks and porches aren't going to be the perfect fit for every new outdoor living space.
