Cement Board Siding

Cement Board Siding Features

Cement board siding is manufactured by several different companies including James Hardie (Hardieplank), Certainteed (Weatherboards), and Nichiha. Usually cement board siding is about 1/4" thick and comes in several different exposures or reveals including 4", 5", 6", and 7". Most manufacturers make cement board siding in a smooth finish and a wood texture finish and it's available in both lap style (clapboard) and shingle style. In years past cement board siding (also known as fiber cement) was only sold in a raw or primed finish with the need for post installation painting. More recently manufactures have introduced planks with a factory applied paint finish.

Problems with Cement Board Siding

Cement board siding is generally a good siding option but in recent years some problems have become known. When installed against or near surfaces such as roofs, landings, or other horizontal surfaces, cement board siding can absorb moisture and delaminate. Pre-finished products and field painted products are both known to peel when installed improperly or near surfaces where water or snow gather, splash, or flow.

When installed properly cement board siding is still one of the better siding options available. When considering a siding replacement project, evaluate the proper installation procedures and be sure to hire a contractor who has experience and expertise with your product of choice.
