The Metal Galvanised Insulation Discs by Timco are an easy and effective way of securing insulation materials to a batten. It's achieved by using a drill and pushing the screw through. Which is then secured using a metal insulation disc.
This pack only provides the insulation discs and not the screws. Each of these insulation discs has a large surface area of 35mm, allowing it to hold more insulation in place.
