Product advantages

Directional flexibility for cylindrical and conical equipment.

Parallel microporous slats let a large SlatFlex panel bend around pipes and vessels. The glass-cloth envelope keeps it together for clean handling.

01

One-direction flexibility

Parallel microporous slats allow the panel to bend across a principal axis and follow cylindrical or conical surfaces.

02

Large-area handling

The glass-cloth envelope keeps the slats together as one clean, manageable panel.

03

Hydrophobic option

A hydrophobic grade is available where contact with water or condensation needs to be considered.

Product construction

Parallel microporous slats contained as one foldable panel.

Made-to-measure slats are encapsulated in glass cloth. Their orientation sets the bending direction and the radius the panel can follow.
