Conventional stucco siding can create a visually appealing exterior. It is made from a combination of limestone, sand, water and Portland cement, and is applied on top of a wire framework or metal screening like chicken wire. One of the biggest advantages of conventional stucco siding is that it is a long term investment. It is durable and strong, and can last for a very long time. Another major advantage is its strength and it is fire proof. Conventional stucco has the added benefit of offering good heat insulation, keeping homes cool when located in hot climates.
