Plastic Insulation Support Fixings 8 x 70mm (100/Pack)

Plastic Insulation Support Fixings with an 8mm shank diameter and 70mm length. Designed for secure retention of lightweight and medium-density insulation boards to masonry and concrete substrates. Manufactured from durable, impact-resistant polypropylene to ensure consistent anchorage without thermal bridging. The wide disc head provides firm contact with the insulation surface, minimising surface compression and maintaining insulation integrity. The plastic expansion zone allows for tight fitment in drilled holes, giving stable performance in both solid and lightweight blockwork. The 70mm length suits medium-thickness insulation boards and applications requiring deeper embedment depth.
