Envirograf Intumescent Putty – 5 kg

Intumescent putty to seal gaps around metal pipes, cables or trunking.

Envirograf® intumescent putty, buff in colour, however, the colour may vary. Applied like normal putty. Can paint over, and, stays permanently flexible internally. Additionally, unaffected by the effects of moisture. Ideal around copper pipes and cables, and around electrical trunking. For filling in small holes and joints up to 50mm wide. Also, the intumescent swells as a result of heat exposure. Thus leading to an increase in volume and decrease in density. Therefore, preventing the spread of fire whilst holding a secure seal.

Subjected to a fire test in accordance with BS746 Part 22 (1987), achieving integrity of 97 minutes.

  • Ideal for filling round metal pipes and cables where they penetrate a range of substrates – If using round glass in steel frame the putty must be painted over to seal surface
  • Can be used to face PVE/A Foam (Product 44) to provide additional fire protection
