Uses
Construction material
Deodar is in great demand as building material because of its durability, rot-resistant character and fine, close grain, which is capable of taking a high polish. Its historical use to construct religious temples and in landscaping around temples is well recorded. Its rot-resistant character also makes it an ideal wood for constructing the well-known houseboats
A houseboat is a boat that has been designed or modified to be used primarily as a home. Most houseboats are not motorized as they are usually moored or kept stationary at a fixed point, and often tethered to land to provide utilities. Ho ...

, Kashmir. In Pakistan and India, during the British colonial period, deodar wood was used extensively for construction of barracks, public buildings, bridges, canals and railway cars. Despite its durability, it is not a strong timber, and its brittle nature makes it unsuitable for delicate work where strength is required, such as chair-making.

The inner wood is aromatic and used to make incense. Inner wood is distilled into essential oil. As insects avoid this tree, the essential oil is used as insect repellent on the feet of horses, cattle and camels. It also has antifungal properties and has some potential for control of fungal deterioration of spices during storage. The outer bark and stem are astringent.
Because of its antifungal and insect repellent properties, rooms made of deodar cedar wood are used to store meat and food grains like oats and wheat in Shimla
