Significant energy saving is the main incentive and basis for green building in Israel. In this world, in which energy prices will be unpredictable in the next several years, it is crucial to apply technology and reduce the consumption of fossil fuels and fossil fuel derived products, which are the main energy sources nowadays, including electricity generated at least partly in coal burning power plants. Thermo House develops, imports and installs insulation solutions for old and new buildings, in which cutting edge green construction is matched with great energy savings. With these methods we are able to insulate entire structures built without proper awareness of energy efficiency issues. This is done simply and easily by attaching insulation to the building's surfaces and covering it with special plaster. This process does not change the buildings' appearance yet their energy consumption drops tremendously in comparison with buildings that were not treated according to this method.
