I-Form Lead substitute

I-Form, the innovative lead substitute made of EPDM (ethylene propylene diene monomer), significantly contributes to numerous construction projects by combining sustainability, flexibility, and environmental friendliness. As an alternative to traditional lead in construction, I-Form presents a promising solution, unlike the well-known heavy weight and environmental issues associated with conventional lead. As the manufacturer of I-Form, we offer the option to choose the lead substitute that best suits your project, facilitating swift, efficient, and aesthetically pleasing completion.


I-Form possesses several distinctive features that make it exceptionally suitable as a lead substitute:

  • Lightweight, easing transportation and enhancing overall efficiency.

  • Flexibility and malleability; in contrast to lead, I-Form maintains its integrity in various climatic conditions, preventing cracking and deformations due to temperature fluctuations.

  • Environmental friendliness; manufactured from EPDM, I-Form is free from lead and other harmful chemicals, in contrast to traditional lead known for releasing detrimental substances into the soil and waterways.

  • Durability; the material boasts a long lifespan, requiring minimal maintenance, and remains functional for many years under the influence of UV radiation, chemicals, and aging.

  • 100% recyclable; after use, I-Form can be fully recycled, allowing the processed raw materials to be reused.


I-Form is composed of three layers:

  • A top layer consisting of EPDM rubber.

  • An intermediate layer of specially designed aluminium expanded metal.

  • A bottom layer of EPDM rubber with protective film.

Our lead substitute is available in 3 colours: black, red and grey. Additionally, various finishing options on the backside can be chosen, including fully adhesive, 1 or 2 butyl adhesive strips or non adhesive. Since we handle production in-house, special dimensions or finishes are possible, ensuring a perfect fit for the construction projects you need to execute.
