Masonite is a type of hardboard made of steam-cooked and pressure-molded wood fibres in a process patented by William H. Mason.〔(The History of Masonite )〕 This product is also known as Quartrboard,〔(Masonite : insulation, presdwood, quartboard, lath, tempered presdwood, tempritile, cushioned flooring. (1935) )〕 Isorel, hernit, karlit, torex or treetex.〔(SvD: Masonit i våra hjärtan )〕 ==History== A product resembling masonite (hardboard) was first made in England in 1898 by hot-pressing waste paper.〔Akers, 1966, p. x〕 Masonite was patented in 1924 in Laurel, Mississippi, by William H. Mason, who was a friend and protégé of inventor Thomas Edison. Mass production started in 1929. In the 1930s and 1940s, Masonite was used for many applications including doors, roofing, walls, desktops,〔Danelectro〕 and canoes. It was sometimes used for house siding. Similar "tempered hardboard" is now a generic product made by many forest product companies. The Masonite Corporation entered the door business as a supplier of facings in 1972, and was purchased in 2001 by Premdor Corporation, a door maker, from its former parent International Paper; it no longer supplies generic hardboard. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「masonite」の詳細全文を読む スポンサード リンク
