Durex® Extreme Impact Lamina is comprised of 2 layers of Durex® High Impact Mesh as a reinforcement layer for a polymer-modified and polymer-based cementitious base coat, followed by an additional layer of Standard Impact Mesh and basecoat, totalling 3 reinforcement layers. It is used as the ultimate reinforcing mesh layer in Durex® EIFS Systems and Durex® Stucco Lite System (except for mechanically fastened EIFS systems).
- Capable of withstanding 40 - 60 N.m/cm2 impact forces without breakage of the reinforcement layer
- Forces equivalent to a 2x4 14ft Long - 9lbs @ 55 kph, or;
- 10 Heavy Strikes with an 8lb Sledge Hammer
- Fibreglass mesh of tested quality, capable of withstanding high tension without stretching
- Glass fibres with negligible sensitivity to temperature changes within the wall
- Proper fibreglass anti-alkaline dressing to avoid quick aging of the wall reinforcement due to corrosion action of alkalis present in coating mortar
- Provides dimensional stability and enhances performance
- Extreme Reinforcement Mesh for the base coat layer in all Durex® EIFS Systems when superior and ultimate impact resistance is required
