We supply ICF Lintel blocks for the 150mm 166mm and the 200mm blocks.

These lintel blocks are 150mm deep and when fixed under the 10th course of blocks the bottom of the lintel block measures 2.12 meters from the floor. Which is generally the standard window height.

Before filling with concrete the steel reinforcing has to be suspended in the middle of the lintel block and extends 500 mm either side of the window opening.

The lintel block should be supported by a piece of timber and some timber props the carry the weight of the concrete until it sets.
