Traditional fieldstone veneer features rounded stones. The front of the individual tiles look like stone pulled from a field. The back of the stone is flat, and ready to be installed with mastic to a properly prepared surface. After the veneer siding is installed, mortar is used to fill in the gaps between the stones. The resulting work resembles a wall built from stones pulled from a field or quarry.
Flat ledge rock resembles shale, or stones pulled from the edge of a river. These stones are thin, and rectangular. They are installed using the same process as the round fieldstone. The advantage of the flat ledge style siding over the fieldstone is additional mortar is not required between the pieces of siding. The flat profile allows the rocks to lie very close together, on top of one another. When installed, this style siding creates a deep, 3-D textured surface.
Manufactured fieldstone siding provides builders with many advantages over real stone work. These products install as veneer over the top of traditional wood stud constructed buildings. The product is lighter than real stone, and the manufacturers create premolded stone corners. When using real stones, the pieces would have to be cut and chiseled to fit around the building's corners, creating a huge amount of custom work, and time expense. The premolded corners install as easily as the flat siding pieces, and do not slow down the installation work.
Another type of fieldstone veneer siding, larger panels are created with a surface that resembles the individual stone surface. These panels don't feature quite the same amount of relief and detail as the individual stones. The stone panels increase the rate at which the siding is installed. Each panel is designed to interlock with every other panel.
Rather than create stone brick veneer from actual masonry composite products, polyurethane chemistry is used to create faux rock veneers that resemble fieldstone siding, ledge style square siding, as well as traditional brick veneer. These panels mix ultraviolet stabilizers, and scratch resistant additives into the polyurethane to create a veneer siding with the texture and feel of the rock, and brick veneer. This technology creates a strong and lightweight faux stone siding. The faux stone also adds an insulating property to the complete project, which fieldstone veneers cannot duplicate.
