Leviat Announces Range Extension of Ancon IHR Head Restraints, Now Accommodating 100mm Gaps

Customer demand and changes to fire regulations have driven Leviat to successfully re-engineer the Ancon IHR range of internal head restraints. The range extension now accommodates gaps at the wall head of up to 100mm, extending the previous maximum of 75mm.

Head Restraints provide the necessary support at the top of masonry panels. Their purpose is to allow for vertical movement to accommodate shrinkage or thermal movement of the wall or structural frame, while restraining lateral loads

The Ancon IHR comprises an L-shaped channel stem and a sliding top section. The channel stem is to be fitted in the bed joint and perpendicular joint of the top masonry course, and the sliding top section slides in the channel, accommodating vertical movement between the blockwork and the structure.

The sliding top section is now available in three lengths; one length to suit 25-50mm gaps, one for 51-75mm gaps, and a longer length for 76-100mm gaps. The longer length has been specifically engineered to meet the needs of customers, and is ideal where a fire or acoustic barrier is being installed or greater deflections are expected in the primary structure.

The IHR suitable for a 100mm gap will be available in April 2024. For more information, click here.
