Roof purlins are horizontal structural members that provide support for the roof deck and transfer the weight of the roof to the main structural elements of the building. They are typically placed perpendicular to the roof rafters and are supported by the building's walls or vertical roof supports. Roof purlins are an essential component of many types of roofs, including sloped roofs, flat roofs, and curved roofs. They are commonly used in commercial, industrial, and residential construction, and can be made from a variety of materials, including wood, steel, and aluminum. One of the primary functions of roof purlins is to provide additional support for the roof deck. By distributing the weight of the roof evenly across the building's walls or vertical supports, purlins help to prevent sagging or buckling of the roof deck. This is particularly important for roofs with heavy loads, such as those that support solar panels or green roofs. Roof purlins also play an important role in the energy efficiency of a building. By providing additional insulation, they help to prevent heat loss or gain through the roof. This can result in significant energy savings, particularly in buildings with large roof areas. In addition to their structural and energy-saving benefits, roof purlins can also be used to create architectural interest. They can be exposed and finished to create a rustic or industrial look, or concealed within the roof structure for a more streamlined appearance. Overall, roof purlins are a critical component of many types of roofs, providing structural support, energy efficiency, and architectural interest. Their design and construction must be carefully considered to ensure that they are able to withstand the weight of the roof and any additional loads, while also providing the desired aesthetic and energy-saving benefits.

Masonry has been an integral part of architectural history for thousands of years. Roof purlins are a structural component of roofs, placed between the rafters and the roof decking to provide support. The use of roof purlins dates back to the Ancient Romans, who used them for structural support for their temples. Roof purlins have been used in a variety of styles throughout history, from Gothic to Tudor, and are still used in modern masonry construction today. The purlins are usually made from metal or wooden beams, depending on the weight load and size of the structure. The metal purlins are usually galvanized steel or aluminum, while wooden purlins are usually made of timber or plywood. Roof purlins are also an important part of energy efficiency as they provide additional insulation, preventing heat loss or gain.
