Hi!, I give you a Blender cycles shader for glass I use for archviz and is easy to customize, this use volume this increase the render time but, you can disable, you can download the blend file for free, for use on your blender scene only need to append the material from the GlassShader blender scene or inclusive the node, the two options work fine :D
