Dryvit Outsulation Systems are engineered, rigorously tested, Code compliant, exterior claddings that provide beauty and protection for the vertical wall surfaces of the building envelope.

Similar to stucco, they are highly energy efficient insulated cladding system that place insulation on the outside of the wall, where building scientists say it is most effective. Literally, the Systems function as a vapor permeable blanket for the building.

Vinyl siding is made of PVC or polyvinyl chloride and comes in a variety of colors. The panels are installed from the bottom row up by nailing galvanized roofing nails through the slots in the panel, exposing the nail head so the panels can move. The vinyl expands and contracts in hot and cold weather and must slide freely from side to side. Two main advantages to vinyl are it's inexpensive and never needs painting.

Manufactured siding can be created from almost any material and made to resemble natural wood. Some composite siding is made from shredded wood, binders, glue and Portland cement. James Hardie is a well known manufacturer of fiber-cement products -- built to withstand rain, wind, hail and insects -- and this siding is available in a variety of colors and warrenty options.
