Thermal protection

The thermal protection in the building engineering participates a question of the hygiene in same measurement like the economic viability and energy-saving. Certain minimum-va- lues of the heat-protection, that are determined in DIN 4108, must be kept to the attainment of dry, cosy apartments. Points of view the economic viability and energy-saving participate the basis of the energy-saving-ordinance. It unites heat-protection-ordinance and heating-appliances-ordinance and gives higher requests as both previous directions alone. The en- ergy-saving-ordinance is aimed at saving yet more heat energy and to give an contribution to the decline of CO2-emissions.
