Envirograf IP021 Intumescent Pads
The Envirograf IP021 Intumescent Pads provide passive fire protection inside plastic and metal cable trunking systems. Their adhesive backing allows the pads to be attached inside the trunking where cables pass through walls or ceilings.
When exposed to fire, the intumescent material expands and compresses around the cables, helping fill the full width of the trunking and restrict the spread of fire through the opening. The Envirograf IP021 Intumescent Pads are lightweight and can be cut to suit different trunking sizes and shapes.
