Joluka Head Restraint Ties

Provide the necessary restraint to the top of masonry walls while allowing vertical movement.
This is necessary to accommodate shrinkage or expansion of the wall or structural frame, while resisting wind loads.

Whilst it is possible to design a wall without the need for restraint at the top, it can be uneconomical to do so as this might require the use of thicker/stronger blockwork and/or the inclusion of bed joint reinforcement to ensure that the panel is sufficiently strong. It is common practice to include head restraints to most types of wall, particularly in external cavity walls where lateral loads are greatest.
