Buiandrug Porotherm A12

The Porotherm A12 lintel is a prefabricated element made of prestressed reinforced concrete with a ceramic casing. Porotherm A12 lintels are placed at the top of the openings provided in masonry for windows and doors, supporting the section of masonry or the reinforced topping above them. These elements can be used on both exterior and interior walls, for openings ranging from 0.25 to 2.50 meters, in new buildings or in renovation, re-partitioning or attic-conversion work. Using this type of product eliminates the formwork, reinforcement, pouring and form-removal work typical of conventional lintels.
