Material

Schluter-BEKOTEC-EN/US/P is manufactured using closed-cell expanded polystyrene and is suitable for use with conventional mortar and poured screeds. BEKOTEC-EN/US/P requires no special disposal and can be recycled. No CFCs or HCFCs are present in either the material or the manufacturing process.

The expanded polystyrene foam used to manufacture Schluter-BEKOTEC-EN/US/P is treated with a flame-retarding agent. The foam is self-extinguishing and achieves an HF-1 rating  according to UL 94. Expanded polystyrene should not be exposed to hydrocarbons, esters, amines, and aldehydes. Common examples include solvent-based adhesives and diluting agents, oil-based paints and stains, and petroleum fuels such as gasoline and kerosene. All will deteriorate foam. Exposure to ultraviolet rays (sunlight) for long periods of time will result in partial degradation (dusting) at the surface.
