Contact layer dressings – or contact layers – are thin, non-adherent sheets made of woven or perforated material. You place contact layers directly on the open wound bed to protect the tissue from direct contact with the wound dressing.
There are two types of contact layers: traditional and silicone.
Modern, silicone contact layers offer a two-fold benefit. They protect the wound from trauma during dressing changes, and they allow exudate to pass freely through the contact layer to an absorbent secondary dressing.
