1. General Over the past few years, underfloor heating has become highly popular for heating homes and industrial buildings. What was once considered to be relatively expensive can now be fitted or retrofitted in almost any building at low cost. The advantages are not only the cosy warmth provided and architectural freedom in interior design, but also the low flow temperature and energy saving aspects. Lower energy consumption means lower heating costs and a lower CO2 impact on the environment. This enables optimal use of renewable energies and condensing heating technology. Heat pump systems...

Standard Description EN 1264 states the minimum thermal resistance value (called U-value) in buildings. Heat insulation requirements for Germany are defined in the Energy Saving Ordinance (EnEV) and can exceed the values specified in EN 1264 in some cases. The specific heat loss of a building can be calculated by an architect or energy adviser taking into account the total thermal envelope. The assessment of the energy efficiency is documented in an energy performance certificate. The U-values of the respective components are documented in the energy pass and are compulsory for contractors. On...

Installation of the MAINFLOOR dry construction system is subject to the following conditions: Substructures must be dry, firm, rigid and free from cracks, dirt and parting compounds must be removed. The dry construction elements must have full contact and rest flat against the substructure as the load distribution layers in dry construction systems are unable to compensate for any unevenness. Any unevenness must be compensated by appropriate measures. This can take place with dry fill material or earth-moist insulation; depending on the particular requirements, other compensating methods that...
