"Inofin FR - The FPO-Membrane with the highest security
offers you a wide range of advantages."

Flexible Polyolefin

The standard for high quality

Inofin FR is made from flexible polyolefin (FPO), a special recipe of ethane-butyl-acrylate. This new Wolfin-developed membrane does not contain rubber and, compared to normal FPO-membranes on a polypropene basis, there is much less fire risk which is even more reduced by further fire prevention additives.

Fire resistant

For the highest standard of fire protection

FR = Fire resistant. With the FR in the name of the Inofin membrane we want to emphasize the fire resistance of this product.

On EPS-insullation or even mineral-wool-insullation, all the needs acc. to BROOF (t1)  are fulfilled.  

No need to clean the joints

Flexible and user friendly

Inofin FR is a specially flexible and user friendly material. Cleaning of the joint-seams before welding is not necessary. This advantage saves you time in the laying process. A further advantage is the high welding period, this offers you the chance to work at your own pace. An extreme change in the welding temperature will also not directly lead to a fault in the welding/seam.   

Joint adhesion

Inofin FR contact adhesive

For joint adhesion on fixed elements, we developed a special Inofin FR contact adhesive. It is a solvent based, ready to use adhesive on a basis of synthetic-rubber.

The INFOIN contact adhesive completes our Inofin FR waterproofing range and offers you the highest security.
