weber.therm 507
Product formerly named: maxit therm 75 Dämmputz
weber.therm 507
Mineral insulating render with low thermal conductivity
Product features
- particularly suitable as additional insulation of heat-insulating masonry
- high decoupling effect of the overlay render (top coat); hence low tendency to cracking
- excellently suited as interior thermal insulation in renovation areas
Product advantages
- high yield
- low tension when hardening
- for mechanical and manual application
weber.therm 507 is a heat-insulating underlay render that can be used both as additional insulation and as levelling mortar for deep unevennesses on masonry, such as lightweight vertically perforated bricks, lightweight concrete or aerated concrete.
