The water drains into a gutter that is fed into a downpipe. A flat roof should have a watertight surface with a minimum finished fall of 1 in 80. They can drain internally or to an eaves gutter, which has a minimum 1 in 360 fall towards the downpipe. [7] The pitch of a pitched roof is determined by the construction material of the covering. For ...
Leader heads or conductor heads [1] are components of a roof drainage system which are known by different names, but they all mean the same. They are funnel-shaped elements, connected in most cases to a gutter, and from there to a downspout. [2] The downspouts take the water run off from the roof that is collected in the gutters to the ground ...
A flat roof is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. [1] Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof. Flat roofs, or "low ...
Metal baffles at the roof drain inlets reduce the injection of air which increases the efficiency of the system. [68] One benefit to this drainage technique is reduced capital costs in construction compared to traditional roof drainage. [66] Another benefit is the elimination of pipe pitch or gradient required for conventional roof drainage piping.
An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
A downspout, waterspout, [ 1] downpipe, drain spout, drainpipe, [ 2] roof drain pipe, [ 3] or leader is a pipe for carrying rainwater from a rain gutter . The purpose of a downspout is to allow water from a gutter to reach the ground without dripping or splashing down the building structure. Downspouts are usually vertical and usually extend ...
A mansard or mansard roof (also called French roof or curb roof) is a multi-sided gambrel -style hip roof characterised by two slopes on each of its sides, with the lower slope at a steeper angle than the upper, and often punctured by dormer windows. [ 1][ 2][ 3] The steep roofline and windows allow for additional floors of habitable space [ 4 ...
Vertical, metal furring is applied to the wall to create a channel and receive the siding material. In construction, furring (furring strips) are strips of wood or other material applied to a structure to level or raise the surface, to prevent dampness, to make space for insulation, to level and resurface ceilings or walls, [1] or to increase the beam of a wooden ship.
