In 2005 I read article about a super wood called Accoya. They said it could not be bent and maintain shape. So, we took on the challenge in 2011 and bought our first “load” of Accoya. We manufactured an ocular window. Since, we have manufactured two complete houses windows + doors with Accoya, in an assortment of window and doors styles; top hung single hung format, French casement pairs, mechanized top hung transoms, plank + V-groove doors. We are actively promoting Accoya as a long term wood replacement solution for heritage components, windows + doors.
