Correct spelling for the English word "Perpender" is [pˈɜːpɛndə], [pˈɜːpɛndə], [p_ˈɜː_p_ɛ_n_d_ə] (IPA phonetic alphabet).
Perpender is a noun that refers to a structural component commonly used in construction and architecture. In the context of building walls, a perpender is a short horizontal stone, brick, or block that is laid across the thickness of the wall to tie the inner and outer layers of masonry together. It is typically placed intermittently between the vertical courses of bricks or stones.
The purpose of perpenders is to enhance the stability and strength of the wall by connecting the outer façade with the inner load-bearing structure. By interlocking the two layers of the wall, perpenders help distribute the weight and forces evenly, reducing the risk of cracking or potential collapse.
Perpenders are particularly vital in load-bearing walls as they provide lateral support and contribute to overall structural integrity. They play a crucial role in preventing the wall from bulging or separating, reinforcing the stability of the building. In addition to their functional purpose, perpenders also improve the aesthetics of the wall by providing visual continuity between the vertical courses of masonry.
The term "perpender" is mainly used in the context of traditional construction methods involving stone or brick walls. It has deep historical roots, and its usage can be traced back to ancient architectural practices. Today, perpenders are still employed in various architectural styles, particularly in heritage restoration and conservation projects.
A large stone in a building reaching through a wall and appearing on both sides of it; a through-band; a coping-stone.
