Insulation with inspiration

How does the façade stay nice and clean? 

Insulation in the form of external thermal insulation composite systems has been proven for more than 50 years in the energy optimisation of buildings. The homeowner does not need to make any compromises, externally insulated walls lend themselves to good durability and cleanliness. Depending on the location and weather conditions, both insulated and uninsulated walls can be affected by microorganisms. The effects are only visual and pose no danger to humans or buildings.

Know the risks and how to avoid them 

Algae and fungi have inhabited the earth for much longer than humans; their spores are virtually everywhere. Where they multiply and settle down however, depends on environmental conditions. Because water is the one thing that algae and fungi need to grow, façades that are permanently exposed to the moisture are therefore more susceptible than walls that are in dry regions or are particularly well protected by structural measures such as large roof overhangs.

The most common risks for algae and fungi are: 

Weather and location: Generally, houses in areas with frequent rain are at risk more than those in drier climates. In addition, the proximity to water, location in a shady valley or areas prone to mist and/or fog are also risk factors. In these environments, there is an increased risk of dew condensation overnight. Externally insulated walls are a positive measure against such environments because they minimise the heat loss from the inside and as the outer walls do not conduct heat as much, remain cool on the outside. This in turn allows the moisture to remain longer on the wall and maintain the faster cooling during the night.  

Building Construction: The construction of a house may even determine the susceptibility of the normal insulated stucco facade. Low roof overhangs and narrow window sills, for example, increase the burden of hard rain. It can lead to unwanted water trail marks therefore, you have to pay great attention to proper water management when attaching the wall insulation. 

Technology for your wall 

A façade that stays clean with long-lasting colour is the desire of every homeowner. When choosing the final layer for your home, it is therefore worthwhile to invest in quality products. The key to success is technology. Caparol has set a new standard with nano-quartz (NQG) technology. This innovation from Caparol enables exterior paints and renders to be very water resistant and weatherproof whilst also having diffusion capabilities. The final layer works in such a way that moisture can escape from inside to the outside, but no moisture can penetrate from the outside to the inside. 

A key feature of exterior paints and renders with NQG Technology is that the surface dries faster than with products coated with conventional materials and provides even less of a breeding ground for microorganisms. 

The shades of the colour fan "façade A1" façades have a very long and brilliant colour stability. This is due to the exclusive use of mineral, natural pigments in these colours and the simultaneous stabilisation of the colour layer. This works in conjunction with the extremely hard surface of the coated surfaces with NQG products.

NQG products have the advantage of a special binding agent which makes them so hard that dirt particles can not manifest on the surface.

Individual solutions for individual façades

This new Nano-Quartz technology improves the resistance of buildings against fungi and algae significantly. But façades that are exposed to moisture often need extra protection. For façades, growth-inhibiting formulas that are mixed into paint and render enhance the resistance of the wall against fungi and algae. These additives are called biocides and are also found in other everyday products, such as anti-dandruff shampoos.
