Slate Roof
Roofing slates are roofing tiles made out of slate. The rock is split into thin sheets which are cut to the requires size before shipment. This contrasts to slabs which are milled to produce larger structural components. They are the primary product of the slate industry. History The Romans were the first to mine and install standard-sized slate on roofs. In his writings, Pliny the Elder mentions the existence of slate in Liguria, near Genoa. Modern production The world's biggest consumer of slate is France, followed by the UK, USA and Germany. In 2012, Spain produced more than of slate worth about $380 million. This made it the largest slate producer in the world, followed by China and Brazil.

Roofing Tiles
Roof tiles are overlapping tiles designed mainly to keep out precipitation such as rain or snow, and are traditionally made from locally available materials such as clay or slate. Later tiles have been made from materials such as concrete, glass, and plastic. Roof tiles can be affixed by screws or nails, but in some cases historic designs utilize interlocking systems that are self-supporting. Tiles typically cover an underlayment system, which seals the roof against water intrusion. Categories There are numerous profiles, or patterns, of roof tile, which can be separated into categories based on their installation and design. Shingle / flat tiles One of the simplest designs of roof tile, these are simple overlapping slabs installed in the same manner as traditional shingles, usually held in place by nails or screws at their top. All forms of slate tile fall into this category. When installed, most of an individual shingle's surface area will be covered by the shingles overl ...

Slate
Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism. It is the finest-grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate, called " slaty cleavage", is caused by strong compression in which fine-grained clay forms flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation with a specialized tool in the quarry, many slates display a property called fissility, forming smooth, flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen ''en masse'' covering roofs. However, slate occurs in a variety of colors even from a single locality; for ...

Slate Industry
The slate industry is the industry related to the extraction and processing of slate. Slate is either quarried from a ''slate quarry'' or reached by tunneling in a ''slate mine''. Common uses for slate include as a roofing material, a flooring material, gravestones and memorial tablets, and electrical insulation. Slate mines are found around the world. 90% of Europe's natural slate used for roofing originates from the Slate Industry in Spain.European Association of Mining Industries website retrieved on 26/01/2010 The major slate mining region in the United Kingdom is the Lake district, with Honister slate mine being the last working slate mine, the only producers of the world famous Westmorland greenslate.

Pliny The Elder
Gaius Plinius Secundus (AD 23/24 79), known in English as Pliny the Elder ( ), was a Roman Empire, Roman author, Natural history, naturalist, and naval and army commander of the early Roman Empire, and a friend of the Roman emperor, emperor Vespasian. He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is Lost literary work, no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used ''Bella Ger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roofing Material
Domestic roof construction is the framing (construction), framing and roof covering which is found on most detached houses in cold and temperate climates. Such roofs are built with mostly timber, take a number of different List of roof shapes, shapes, and are covered with a variety of List of commercially available roofing material, materials. Overview Modern timber roofs are mostly framed with pairs of common rafters or prefabricated wooden trusses fastened together with truss connector plates. Timber framed and historic buildings may be framed with principal rafters or timber roof trusses. Roofs are also designated as ''warm'' or ''cold roof'' depending on the way they are designed and built with regard to thermal building insulation and Ventilation (architecture), ventilation. The steepness or roof pitch of a sloped roof is determined primarily by the roof covering material and aesthetic design. Flat roofs actually slope up to approximately ten degrees to shed water.

List Of Commercially Available Roofing Materials
Roofing material is the outermost layer on the roof of a building, sometimes self-supporting, but generally supported by an underlying structure. A building's roofing material provides shelter from the natural elements. The outer layer of a roof shows great variation dependent upon availability of material, and the nature of the supporting structure. Those types of roofing material which are commercially available range from natural products such as thatch and slate to commercially produced products such as tiles and polycarbonate sheeting. Roofing materials may be placed on top of a secondary water-resistant material called underlayment. Steep slope roofing materials Steep roof materials are roofs that are only recommended where water can freely and openly drain off the edge of the roof without retaining water for too long. The aim is to drain off water completely due to the high water permeability of most of these materials, for instance: the Thatched roofs. In areas where the I ...

Slate Industry In Wales
The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then rapidly during the Industrial Revolution in Wales until the late 19th century, at which time the most important slate producing areas were in northwest Wales. These sites included the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops, headstones as well as high quality surfaces for games such as shove ha'penny, snooker and billiards.Lindsay p. 133 Up to the end of the 18th ...

Roofs
A roof (: roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice, and may also be governed by local or national legislation. In most countries, a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light. A roof may also provide additional living space, for example, a roof garden.

Stone Buildings
Stone Buildings, Lincoln's Inn were constructed from 1774 to 1780. The architect was Sir Robert Taylor. Stone Buildings is a Grade I listed building. Stone Buildings appear in Anthony Trollope's novel '' The Prime Minister''. Stone Buildings are so-called from the material with which they are constructed. They were constructed in accordance with an ultimately unrealised plan to rebuild Lincoln's Inn entirely in stone. Their construction was the initial step in that plan. The working drawings were made by a young man called Leach, then a clerk in Taylor's office, who later became Master of the Rolls. Leach's drawings are preserved in the Library of Lincoln's Inn. Pitt's chambers appear to have been in Stone BuildingsWheatley and Cunningham. "Stone Buildings, Lincoln's Inn" in '' London Past and Present: Its History, Associations, and Traditions''.
