My home is my castle
In the past, when there were storms and snow, people sought shelter behind thick walls of roughly hewn stone or huge bricks. Today, walls are comparatively streamlined and thin, but the demands made on a façade have remained the same, even in the 21st century.
Protection from all conceivable mechanical and natural threats is provided in modern buildings by a façade with a structure that has been carefully planned in detail, using scientifically proven methods.
The PowerSystem Principle
There are a number of possibilities for designing a strong façade – from simple structural measures to high-tech building materials. The Baumit PowerSystem is the latter, combining the requirements of perfect, modern heat insulation with the strength of solid masonry.
Effective insulation is achieved using a protective shield, several millimetres thick, in which a top-quality textile glass grid is embedded. A top quality Baumit façade render is applied over the top. This protects the layers beneath from moisture and gives the façade an attractive appearance.
Protective shields generally perform best when they are both hard and elastic. And this is the secret of the Baumit PowerSystem: hardness and elasticity are perfectly balanced. Modern architecture without roof projections in particular exposes façades to high stresses. Furthermore, on renewal of thermal insulation with its thicker insulating layers, the protection provided by the façade is considerably lessened as a result of the reduced roof projections. The Baumit PowerSystem is required in both cases.
Elastic impact protection
Its "elastic rigidity" means that the Baumit PowerSystem achieves outstanding performance in the impact strength test as per ETAG 004, even with single reinforcement. The dent test provides impressive proof of this: even at only 3 millimetre reinforcement thickness, this system more than lives up to its name Double reinforcement increases protection up to 70 joules. Hail and other projectiles simply bounce off without leaving a trace.
Indestructible weather protection
The number of storms has increased in recent years, resulting in considerable damage. In the "hail register", building materials are classified according to their resistance. A glance at this shows clearly how a product performed in the test.
Standardised balls of ice created in a laboratory are fired at the building materials by a simulator and the materials are allocated to various "hail resistance classes" depending on their resistance. The most important values are the shot size and the impact energy (joules). The table ranges from HR (Hail Resistance) 1 – with a shot diameter of 10 mm – to HR 5 with 50 mm diameter and a minimum impact energy of 27 joules.
Baumit PowerFlex, a paste-like putty reinforced with aramid fibers, achieves an outstanding Hail Resistance Class 5 with 5 mm layer thickness.
Golf ball-sized hailstones are not the only mechanical threat to a façade. Damage to the façade can also occur in other situations. In schools, nurseries and playgrounds for example, where structures have to be made ball-proof. In carports and garages, where there is an increased risk of scrapes. As well as in busy public entrance areas. Façades insulated with PowerSystem are highly wear-resistant wherever the going gets tough.
All round thermal protection
As an important component of the Baumit PowerSystem, Baumit PowerFlex is optimised to achieve the best heat insulation. Applied as an undercoat, Baumit PowerFlex together with the Baumit ProTherm façade insulation panels make a great team. Baumit PowerFlex can be used in a nominal thickness of 3 mm or 5 mm, depending on the stress load.
Strong, economical and practical
Furthermore, the strong reinforcement mortar is highly economical, because even a single reinforcement layer achieves high impact strength and hail resistance classes.
