Scope of use

TERMOFLEX® WHITE 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. The solution is highly steam permeable and resistant to freezing and temperature changes. The content of special lightweight additives and plasticizers make the mortar more elastic and add up light and homogenous consistency, which makes its spreading much faster and easier and at the same time significantly reduces the material consumption.

TERMOFLEX® WHITE 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. The air-drawing additives in the mortar increase its thermo-insulation characteristics with more than 10%.
