Make your own lintel

We have an extensive range of U-shells made of aerated concrete. These are U-shaped elements that serve as formwork for the lintels. With the U-scales you can determine the length of the lintel yourself. They are easy to process because you place them directly in the work. So there is no need to arrange a crane to lift heavy lintels into place!

After creating a temporary support at the window or door opening, you can place the U shells. If necessary, place the reinforcement cage or steel beam and the extra insulation in this. Then you pour the special construction concrete, after which the lintel is ready.

U-shells made of aerated concrete

The advantage of aerated concrete is that this building material has a high thermal insulating effect. It prevents cold bridges, which are heat leaks. Our U shells can be used in walls that are glued with aerated concrete, but it can certainly also be combined with other building materials such as concrete, brick, Poriso or sand-lime brick.

The U-shells are available for different wall thicknesses:

  • U scale 15 cm
  • U scale 17.5 cm
  • U scale 20 cm
  • U-scale 24 cm
  • U-shell 30 cm
  • U scale 36.5 cm
  • U-shell 40 cm with insulation
  • U-shell 42.5 cm with insulation
  • U-shell 50 cm with insulation
