What are Core Bungs?
The Core Bung is a very quick, lightweight and simple system that is used to make the cores in hollow core beams airtight in order to dramatically reduce energy and heat loss, as well as reduce sound interference.
Made from recycled plastic, the Core Bung, consists of a very thin front face with an injection hole in the middle. They help a structure to comply with Part L and Part E of the building regulations.
See our step-by-step guide below which explains how it works.
