composite siding recallWhat’s the problem with composite siding? Many types of composite siding will become defective or deteriorate prematurely due to lack of or poor maintenance just like real wood. Composite siding is also known to develop problems due to manufacture defects, which have resulted in many class action law suits, some of which are ongoing or coming soon.

Composite siding is man-made boards manufactured for use as exterior siding, made from various combinations of wood fibers, fillers, binders and glue. These mixtures are heated and compressed into composite wood products. There are many types of composite siding which can be divided into a few main groups. Some are large panels similar to sheets of plywood and some are similar to individual clap boards.

Types of composite siding

  • Cement board is a product with Portland Cement added to the wood mixture
  • Hardboard is made from a wood pulp mixture
  • Fiber board is product made with sawdust
  • Oriented stand board (OSB) is common name for product made from shredded wood mixture
  • When used as siding an embossed over-lament is often added to simulate the look of wood
