- hydro and frost resistant




Scope of use

TERMOFLEX® REINFORCING MORTAR FOR EPS & XPS is a high quality construction mortar for making of armored plastering layer with incorporated fiberglass mesh on expanded polystyrene (EPS) and extruded polystyrene (XPS) boards without skin. The mixture is cement based and has excellent adhesion to all types of mineral bases and polystyrene, which makes it suitable for bonding thermoinsulating boards, ensuring their extremely strong bonding to many bases. The cellulose fibers containing in it increase its strength and resistance of the whole thermal insulation system to damages, cracks and blows. The plaster is highly steam permeable and resistant to freezing and temperature changes.

TERMOFLEX® REINFORCING MORTAR FOR EPS & XPS is an element of the integrated thermal insulation systems TERMOFLEX® CLASSIC and TERAPOR® ULTRA and is suitable both for newly erected buildings and old buildings – during the process of renovation and improvement of their thermal insulation.
