These orangeries consisted essentially of buildings with a skylight built on top.<\/p>\n<p>However, it wasn\u2019t really until Victorian times that the rooflight became recognisable as the architectural feature we know today.<\/p>\n<p>The Victorians originally designed wood-framed rooflights to bring light into dark agricultural buildings and to illuminate otherwise shadowy spaces such as stairwells. By the time of the Great Exhibition in 1851, industrial developments in metal-work and glazing meant that impressive structures such as the Crystal Palace could be constructed, displaying vast areas of glazing supported by steel frames.<\/p>\n<p>From that point on, rooflights continued to increase in popularity, most loved for their ability to bring in abundant natural light, to increase good ventilation and to enable views of the surrounding countryside.<\/p>\n<p>Today modern rooflights abound, but the conservation rooflight harks back to Victorian times. Designed to imitate the low profile of a Victorian rooflight, conservation rooflights fit flush to the roof rather than projecting above the roof line so they do not detract from the overall character and appearance of a property. Their main distinguishing feature is the \u2018T\u2019 bar down the centre of the window pane which is taken from the original Victorian design. One of the best examples of this \u2018T\u2019 bar feature can be seen in Alfred Waterhouse\u2019s main hall at the Natural History Museum in London completed in 1880.<\/p>\n<p>Despite their traditional looks, modern conservation rooflights boast the features of a 21<sup>st<\/sup> century building products. By allowing abundant natural light to fill a room they reduce the need for artificial lighting, thereby lowering energy consumption and carbon emissions and improving the health and mood of anyone who uses the space.<\/p>\n<p>Clement Conservation Rooflights are available from stock in eight standard sizes, but they can also be tailored to bespoke designs. Available in two profiles, for both slate and tile roofs, they are silicone fronted to give the appearance of traditional Victorian putty glazing. Each rooflight is fitted with a self-cleaning 24mm insulated glazed unit and there is a choice of winders and actuators to make opening as straightforward as possible. Recently awarded an \u201cA\u201d Window Energy Rating by the British Fenestration Rating Council, Clement Conservation Rooflights performed extremely well in rigorous test situations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The rooflight has arguably been a feature of architecture since Roman times when an oculus was included in structures such as the Pantheon in Rome \u2013 from the Latin word for \u2018eye\u2019, an oculus is a circular opening in the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":2413,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[41,42],"tags":[],"class_list":["post-1643","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blogs","category-conservation-rooflights"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>The History of the Conservation Rooflight | Clement Windows<\/title>\n<meta name=\"description\" content=\"The History of the Conservation Rooflight from Clement Windows.
