Ridge-and-furrow

Also called ridge and furrow, ridge-and-furrow roof, ridge-and-furrow glazing

A roof glazed in a series of small ridges and valleys, proposed by J. C. Loudon in 1817 and used by Joseph Paxton at Chatsworth and on the Crystal Palace; the panes meet the low sun more squarely and the folds stiffen the roof.

Rules that use the word

The ridge-and-furrow roof. Glaze a roof in a series of small ridges and valleys, the panes set at an angle on light sash bars, so that the low sun of morning and evening strikes the glass more squarely, the roof is stiffened by its folds, and the rain runs into gutters in the furrows.
