North Light Roof Truss Wikipedia

North light truss this form of truss is usually used for short spans in industrial buildings and is so called because it allows maximum benefit to be gained from natural lighting by the use of glazing on the steeper north facing pitch sometimes referred to as a sawtooth roof.

The simplest form of a truss is one single triangle. North light truss has a asymmetrical profile with a south facing slope at 17 or more to horizontal and the north facing slope at from 60 to vertical. North light is natural light coming from the north in the northern hemisphere. Because of the stability of this shape and the methods of analysis used to calculate the forces within it a truss composed entirely of triangles is known as a simple truss.

They are can be designed with glazing inclined glass panels towards north sky on north side since in northern hemisphere there is no. This sort of roof commonly admits natural light into a factory and is also known as northlight in the northern hemisphere implying a single such plane. A saw tooth roof is a roof comprising a series of ridges with dual pitches either side. A roof appended thus the name to the wall of a building and by implication having further roofs or terraces above.

It is preferred and considered ideal by architects. This type of truss is seen in a framed roof consisting of rafters and a ceiling joist and in other mechanical structures such as bicycles and aircraft. The steeper surfaces are glazed and face away from the equator to shield workers and machinery from direct sunlight this kind of roof admits natural light into a deep plan building or factory. Roofs of long span structures are made of steel trusses.

Because of the steel pitch of the north facing slope the space inside the roof trusses of a north light roof is considerably greater than that of a. It is diffused sun light and hence does not create sharp shadow.
