In construction, a lintel is a beam placed across the top of
an opening in a wall. Used above empty spaces like entrances and windows in
buildings, lintels support the weight of the structures above them. Typically,
the beams fit seamlessly into the wall, matching the width of the wall and
extending past either end of the opening. Mostly used in brick and masonry
buildings, lintels stem from a variety of materials depending on the
structure's support needs, contractor preference and building aesthetic.
Similar to an arch but flat and easier to install, lintels can be an important
structural element in a building.
Where are lintels used?
Lintels support the weight of structures above wall openings,
doorways and windows in primarily brick and masonry buildings. Open spaces in
walls often lack structural integrity because there is nothing above the gap to
support the load on top of the opening. To combat this, lintel beams extend
past either side of the doorway or opening. Builders install them into the wall
to disperse the weight of materials directly atop the open space.
