AERATED COURSING BLOCK (3N) 215mm x 100mm x 65mm

Tarmac coursing units are designed for use with a range of blocks, to avoid thermal bridging and to minimise waste.

These coursing units are used for general coursing work and are ideal for use as a space filler, around doors and windows, for closing cavities between timber floor joists or roof members as well as sills and over lintels.

They are a convenient method of construction rather that the wasteful practice of cutting blocks on site.
