Video: Emission-free Building Materials
With airtight buildings, not only does the heat stay in the house, but unfortunately also the pollutants.
A tight construction is prescribed by the increased requirements of the EnEV. It ensures that the heat stays in the house. This reduces costs and protects the environment. A dense construction also keeps possible harmful pollutants in the house that cannot “ventilate”. The exchange with the outside air (the air exchange rate) is often 10 times lower than in old buildings. Because of their large area and direct contact with indoor air, coatings and coverings on walls, ceilings and floors play a special role.
Kalkin lime plasters take harmful sulfur dioxide as well as greenhouse gas such as CO2. from the ambient air. The latter is simply involved in the carbonation reaction of the lime. The Kalkin lime plasters, tested for zero emissions, are versatile: as a base and top coat; to paint over; to work under tiles and most naturally without coating.
This is the best way for Kalkin to develop its positive properties - regulating the humidity of the room air and absorbing pollutants.
Baumit Kalkin products are independently tested via the environmental product declaration program of the Institute for Building and Environment in Königswinter. An environmental product declaration provides information that has been checked and compared by independent experts and provides comparable information about the environmental performance of products. A further test according to the "Sentinel-Haus Standard" was carried out by the eco-Insitut in Cologne, in which the Baumit Kalkin products were confirmed to be free of harmful substances. This means that a whole range of lime plasters, lime cement and cement plasters, light plasters, gypsum plasters, clay plasters, mineral noble plasters, renovation plasters, adhesive mortars, masonry mortar and screeds, as well as concretes are available to build a new house or to renovate an old building.
