They are traditionally of the barrel type, what is referred to today as cap and pan roof tiles. -- Definition -- Is a specific type of ceramic tile, made of fired terracotta. It is generally semi-cylindrical, made by forming clay around a curved surface and laid in alternating columns of convex and concave tiles. -- Definition -- Composition shingles are the most widely used roofing material. They are also called asphalt shingles that could either be organic fibre mat or fibreglass core. Both types are steeped in asphalt and then coated with mineral granules to add colour and texture. Most shingles have an adhesive back that when reinforced with tacks, staples or nails for attaching on roof frames would result in a tight fit. -- Definition -- Is a roofing material consisting of shingles, simulated wood shakes, lighter-weight tiles and concrete panels manufactured from a variety of fibre-reinforced cement products. -- Description -- NOTE 1: Some are coated with plastics, enamels, or thin metals, and some contain recycled material. NOTE 2: Many concrete tiles mimic the appearance of wood shakes, while improving on the durability and fire protection that real wood affords. It can approximate the look of clay tile or slate while mitigating the structural problems caused by the weight of the real material. -- Definition -- Roofs of corrugated sheet may be of fibreglass, PVC or metal; less frequent is the use of galvanized iron sheet. -- Definition -- Fibre reinforced concrete is concrete containing fibrous material which increases its structural integrity. Fibres include steel fibres, glass fibres, synthetic fibres, asbestos and natural fibres. It is commonly used for the agricultural sector, particularly in livestock buildings. -- Definition -- The surface of the roof is constructed out of glass, typically used in roofs covering internal atriums or in greenhouses. -- Definition -- Hot mopped asphalt roofing is usually applied to flat or semi-flat residential roofs that have good access and proper drainage. In residential use it is often covered with a layer of decorative stone to improve the appearance. -- Definition -- Metal roofing comes in the form of galvanized steel with paint, aluminium with paint, stainless steel, zinc, lead or copper. It is also manufactured in the form of imitation wood shingles. -- Description -- EXAMPLE : Standing-seam steel roofing is the most popular residential metal roofing today (the term standing-seam describes the upturned edge of one metal panel that connects it to adjacent sections, creating distinctive vertical lines and a trendy historical look). NOTE: Metal roofing is sturdy, lightweight, and non-combustible -- Definition -- Roofs constructed out of reinforced concrete, normally along flat or semi-flat surfaces used in terraces or inclined roofs. -- Definition -- Slate is a shingle-like sliver of rock or natural stone, offering a natural look laid out in a variety of patterns. It comes in different sizes and colours, although colours are limited to those found in nature. -- Description -- NOTE: Like tile, slate can be very heavy. -- Definition -- Straw roofs are built by thatching, which is the craft of building a roof with dry vegetation such as straw, water reed, sedge, rushes and heather, layering the vegetation so as to shed water away from the inner roof. -- Definition -- Also known as eco-roofs, a vegetated or green roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. -- Definition -- Wood shingles or shakes are differentiated by size and texture. Shingles are cut to a specific size and have smooth finish. Shakes are rough-textures and are irregular in shape. -- Definition -- Code list for the possible values of attribute documentFormat. -- Description -- This code list includes well-known and easy to handle formats, in order to ensure easy use of documents.

NOTE 1: These unbaked bricks consist of sand, sometimes gravel, clay, water and often straw or grass mixed together by hand, formed in wooden moulds and dried by the sun. When machinery is not available, earth is manually tamped in the mould; else, mechanical compression is used (manual, or motorized presses), in order to accommodate large production outputs of compressed earth blocks. -- Definition -- Unreinforced concrete block masonry, with lime/cement mortar. -- Description -- Buildings of this type have perimeter walls, and possibly some interior walls, constructed of unreinforced concrete blocks joined with lime/cement mortar. These perimeter walls are sometimes used as load bearing walls and have no internal reinforcing steel rods. Anchor plates are sometimes used to tie the walls to the floors and roof and are conspicuous from the outside of the structure. -- Definition -- Rammed earth or pneumatically impacted stabilized earth. Rammed earth construction (also referred to as tapial in Spanish, or else, pisé de terre, in France) is conducted by erecting wooden or metal forms for the walls and filling them with a moist cement stabilized earth mix which is compacted by pounding with hand tools (with conical or flat heads) or with a mechanical compactor. Metal rebar is often added to further increase ductility. -- Description -- NOTE 1: Different kinds of earth or mineral compounds are sometimes added to each earth layer for the sake of decoration. The finished walls are massive and monolithic, offering high strength, high thermal mass and high insulation. NOTE 2: High load bearing strength allows for multi-storey structures, usually based on floor decks supported by massive wood beams. NOTE 3 No surface finishing is used except for aesthetic effect. -- Definition -- Unreinforced fired brick masonry. Buildings of this type have perimeter walls, and possibly some interior walls, constructed of unreinforced fired brick blocks. These perimeter walls are sometimes used as load bearing walls and have no internal reinforcing steel rods. Anchor plates are sometimes used to tie the walls to the floors and roof and are conspicuous from the outside of the structure. Unusual brick patterns may also indicate unreinforced fired brick masonry. -- Definition -- Parts of slums/squatters. Informal constructions are non-engineered and are built by self-builders without any professional input (i.e. neither during the design phase, nor the construction one). -- Description -- NOTE 1: The whole endeavour is usually based on observation from other nearby building sites, or (in the best of cases) on labour experience gained by the owners during their occupation as construction builders. NOTE 2: This type of buildings are in general of low quality and have many deficiencies that makes them very vulnerable to hazards. -- Definition -- Massive stone masonry with with lime/cement mortar. Is constructed with a coursed double leaf masonry, with the outer layers of stonework levelled as the construction progresses and follows a well established masonry bond. The stone units are cut in regular dimensions. To improve the connection between cross walls better quality units are used for the bond in these areas. -- Definition -- A structure designed or adapted for human habitation which is capable of being moved from one place to another (whether by being towed, or by being transported on a motor vehicle or trailer) and any motor vehicle so designed or adapted. -- Description -- NOTE 1: Railway carriages and tents do not count as mobile homes. NOTE 2: though mobile in nature, some mobile homes are installed in perennial way and may be considered as under INSPIRE scope -- Definition -- Mud walls may be made of stacked earth or poured earth. Stacked earth consists in forming balls of plastic soil, which are freshly stacked on each other. Poured earth walls on the other hand are erected between formwork using a sandy material with coarse to fine granular particles. The ultimate finish can be natural - from the formwork- or sand blasted. -- Description -- NOTE 1: The contemporary name of stacked earth is cob ( a name derived from the British Isles). Cob does not use bricks, or blocks. Instead, wall surfaces can be sculpted into smooth, sinuous forms. A cob home may have sloping walls, arches and lots of wall niches. Modern cob construction may top the walls with a concrete bond beam, use a wooden bond beam, or a separate roof frame supported on a post and beam system. -- Definition -- Precast Wall Panel Construction. Buildings of this type are low-rise structures with precast reinforced concrete wall panels that are often poured on the ground and tilted into place. Roofs are often composed of either plywood sheathing or metal decking, and glass curtain walls may exist at the building perimeter. -- Definition -- The load resisting system is made of reinforced concrete, a combination of steel reinforcement bars embedded in concrete that act together in resisting forces. Reinforced concrete buildings may be constructed as moment resisting frames (beams and columns framing at nodes), or in combination with shear walls. -- Definition -- Buildings of this type have exterior walls consisting of grouted (with concrete) masonry (clay brick or concrete block masonry) with internal reinforcing steel rods. -- Description -- Reinforced masonry buildings are relatively thick walled box-like structures and often have small windows and at least two mostly solid walls. -- Definition -- Ruble stone is field stone. Is a masonry technique that incorporates any material found or recovered, such as dressed blocks, broken fragments, brick or flint. -- Description -- NOTE 1: The success of rubble depends on the thickness of the wall and the strength of the binding mortar. If either is too thin, the structure will fail. As it is almost impossible to construct a thin rubble wall, owing to the irregularity of the material and the size of the gaps to be filled by the mortar, in areas or building traditions lacking dressed stone and ashlar technology, rubble walls are likely to be very thick. -- Definition -- The load resisting system of the building is made of structural steel, which may be made composite with reinforced concrete at floor slabs. Steel structures may be constructed as moments resisting frames, as concentrically or eccentrically braced frames, or as spatial trusses. The members of the structure may be bolted or welded. -- Definition -- The load resisting system of the building is made of wood, timber or lumber. -- Description -- Two systems of construction are possible, one based on a frame, the other on a skeleton. Framing is a building technique based around structural members, usually called studs, which provide a stable frame to which interior and exterior wall coverings are attached. In skeleton houses the posts and the horizontal crossbars form a frame (whose strength is sometimes increased by the use of additional diagonal bracings or stiffeners) that is filled in with wood (post or frame and plank constructions) or other materials such as clay, stone, or brick. -- Definition -- This data types provides the address where the document may be found and a minimum set of metadata elements considered as necessary to exploit the document. -- Definition -- Date of validity of the document. -- Description -- EXAMPLES: the date the photo was taken, the date the sketch was done or approved, the date the building permit was accepted -- Definition -- A short text providing overview of the document content.
