Why Does External Wall Insulation Crack? Choosing the Right Plaster and Adhesive

daumer-photo-blog

Insulating a building’s envelope is far more complex than just fixing boards to a wall. Facades are perpetually subjected to severe diurnal temperature shifts, shifting wind loads, and thermal shocks. The most common reasons behind facade cracking and board movement in project sites are utilizing low-flexibility renders or adhesives lacking adequate initial grab. Furthermore, if the system cannot breathe, trapped interior moisture pushes outward, causing the render to crack and eventual system degradation.

The Solution: Fiber-Reinforced and Breathable Smart Mortars To ensure the durability of any ETICS setup, the plaster layer must deliver absolute crack resistance and superior elasticity. Compliant with ETAG 004 standards, DAUMANT TERMOPLAST features synthetic fiber reinforcements that effectively eliminate cracking risks under extreme environmental stress. Its high water vapor permeability allows the structure to breathe smoothly, preventing moisture-induced damage. For the securing stage, utilizing DAUMANT TERMOFIX with its specialized high initial grab prevents board slippage during installation, drastically speeding up field execution. For projects seeking inventory efficiency, the hybrid 2-in-1 formula of DAUMANT MANTELFIX serves as both premium adhesive and plaster in a single bag.
