10 Reasons to Install Marble Window Sills Outdoors

Window sills add to the overall appearance of a structure’s exterior. The placement of natural stone sills is a good investment in the property, and those who install sills made from marble will not only benefit from the strength and durability of this material, they will also be providing a sturdy, long-lasting support for the entire window frame. Although heavy, marble can be supported properly by reinforcing the wood frame, and the result is a very tight water seal that helps lower energy costs and extends the life of the frame itself.
