The Indoor allergens

Naturally antibacterial and anti-mould materials

Indoor allergens such as mites, fungi and bacteria are becoming an environmental contaminant of increasing concern.

The rise in the number of children and young people suffering from asthma in recent years, especially strains that are not seasonal, has raised awareness of our sensitisation to allergens (biological and chemical) present in indoor spaces as one of the main causes of asthma.

Very damp air and damp walls offer the ideal environment for these micro-organisms to grow and proliferate.

GreenBuilding Kerakoll materials with high basic pH are naturally antibacterial and anti-mould, and ensure dry, healthy, disinfected environments, preventing bacteria and moulds from taking root and proliferating to the detriment of the health of the environments and the wellbeing of the people in them.

The tests were conducted at the CSTB Institute – Centre Scientifique et Technique du Bâtiment – Microbiology Laboratory of the Department of Energy-Health- Environment / Health Division, Marne-la-Vallée, Paris, in collaboration with the Pasteur Institute of Paris and the Hygiene and Epidemiology-Mycology Institute of Brussels.

The most common indoor allergens:

BACTERIA
Where are they
Multiply everywhere and incredibly rapidly.
In very short periods of time, unpleasant odours appear.
What do they do
They attach to the wall and effect hygiene and health. They also damage the aesthetics of the wall.

FUNGI
Where are they
Proliferate in humid areas with poor ventilation.
They inflict lasting damage on polymers, form stains and destroy covering materials.
What do they do
They feed on the environment where they take root, degrading the mechanical characteristics of the plaster/render coats and varnishes.

MITES
Where are they
Proliferate in dusty areas and in hot/humid climates (25 °C in temperature, 75% in humidity).
What do they do
Dust mites are one of the main causes of the 5/6 million allergies reported in Italy.

MOULDS AND ALGAE
Where are they
Proliferate in areas with high humidity and need light to multiply.           
What do they do
They deposit and drastically reduce the functionality of the plaster which, waterproofed by these microorganisms, can no longer breathe.
They nest, creating unpleasant green and red stains on the walls.
Strong, insalubrious odours.
