Full Bed Depth Stone (2

1
Full Bed Depth Stone (2-5)

• Building stone comes in many different types.
  Some of the most common are Sandstone,
  quartzite, quartzitic sandstone, limestone,
  travertine, marble and granite.
• Because of the harsh environment in which we
  live, the stones that we use externally must be
  selected carefully.
• Stone must be selected with the environment and
  climate in mind.

Building Stone comes in many shapes and sizes

• Squares and Recs (Rectangles)-most stones need
  to be guillotined or sawn to get this pattern.
  It consists of random sizes of square and
  rectangular patterned stone.
• Guillotined Builder- has been snapped with a
  guillotine to expose the interior of the stone.
  The finish tends to be very rough.
• Random- irregular, more natural shaped stone.
  This tends to be used in the same shape it was
  quarried. Also tends to be flat of depth without
  a great amount of relief.

Building Stone shapes and sizes cont

• Rubble (Boulder)-is used in its natural state,
  similar to the Random stone but tends to be more
  round with a greater degree of relief.
• Ledge-is long and lineal of shape. The best
  ledge stone are those that form in a ledge
  pattern naturally like quartzite. Some other
  stones may be guillotined into a ledge shape.

Building Stone shapes and sizes cont

• Flagstone-is most often used as a floor stone.
  Flagstone must come from a sedimentary formation
  to (flag) properly.
• Float (Gathered) Stone-is not a quarried material
  but is gathered as it lays on the surface. This
  stone will often have colorful lichen. This
  stone is also called a Moss Rock even though it
  is usually not a true moss, but it is lichen that
  forms in the surface of the stone.

Three basic faces of building stone

• Guillotined edge / Split Face- This consists of
  the center of the stone. The stone has been
  split or cut to expose its center. The natural
  coloring here tends to be more uniform from one
  piece to another.
• Natural Cleft- This is the face of the stone that
  is part of the natural seaming in the formation
  of the stone. Water, minerals and sometimes even
  air, have been able to effect the stone. This
  changes its colors making them more vibrant.
• Natural Ledge- Comes from the cracking that
  occurs during the formation of the stone. This
  also allows for the elements to effect the
  minerals in the stone making the colors varying
  and vibrant.

What is Natural Stone Thin Veneer?

• In order to qualify as an Adhered Veneer, the
  stone needs to
• Be less than 15 lbs/sq foot as described in the
  current Uniform Building Code and International
  Building Code.
• Be a nominal 1 ¼ thick but no more than 2 5/8.
  Thicknesses may vary depending on the density of
  the stone.
• No more than 36 in any face dimension and no
  more than 5ft. (2) in overall surface area.
• Typically ½ or less than the thickness of Full
  bed depth veneer.
• Typically 25 or less of the weight of Full
  veneer. The average weight of Full veneer is
  about 50 lbs. per square foot.

Advantages of Natural Thin Veneer

• With the reduction in thickness comes a
  significant reduction in weight. Natural Stone
  Thin Veneer does not require a reinforced
  foundation.
• Remodels and renovations are no problem as weight
  is not an issue. Natural Stone Thin Veneer can be
  applied to any building.
• Easy and less expensive to install than full
  thickness veneers. End users tend to save about
  30 on installation costs alone. Installs the
  same way as manufactured stone only with a
  slightly different spec mix.

8
Disadvantages of Natural Stone Thin Veneer

• Dont have the extreme variation of depth
  (relief) as with Full bed depth veneers.
• Very difficult to create battered columns with a
  high degree of taper with out additional framing.
• Cost is going to be about 10 to 15 higher than
  manufactured stone.
