I-Form the best Lead Substitute

Applying flexible seals can be a tricky job, especially when it comes to roofs, facades, dormer windows and chimneys. Traditional lead products can cause problems such as rusting, cracking and leakage, resulting in high maintenance costs and a reduced lifespan of the structure. This is where I-Form from IPEX comes in as the perfect lead substitute.

Flexible seal that is easy to apply and cut to size

i-Seal is a flexible sealant made of EPDM rubber, special aluminium expanded metal and a bottom layer of EPDM rubber with protective foil. This combination provides a watertight and durable solution. The material is very flexible and can be easily applied to the most complex shapes and surfaces.


The flexibility of the material allows to cut i-Form to size, so that as a manufacturer of prefab constructions you waste less material and can offer lower prices. i-Form is also resistant to extreme weather conditions and will not crack or tear as lead.
