Getting tax credit through energy saving; the role of mineral wool.
Unless one is preparing for leaving planet earth he could be interested on this subject. It is noticeable how much one can save through updating physical elements of a building. First: save from loss of energy that derives from the loss of heat and light. Second: save from a bigger energy income through an inner production, one can have for example through solar panels. Third: save from tax deductions. Fourth: save through getting new income thanks to a policy many western states have adopted. It is a waterfall of savings.
Waterfall of savings
Saving energy is saving money and it's direct and indirect. When we clothe ourselves we are saving heat; actually that's the same principle of when we cover a building. Enlarging walls and insulate a roof is best when made through natural materials. Some of these materials are spectacularly made through complex processes; such as mineral wool. A family that decide to modernise her house can save 10 tons of co2 per year. To get the equivalent saving (and release for the planet) a family should stop using two cars. That's not enough... avoid the summer holiday, stop eating beef, having cold showers. That would be enough.

Don't think the production of mineral wool is energy requiring. It is more spectacular than polluting. Three are the sources: glass, sand and rocks (basalt, dolomite, briquette); first they are fuse at more than 1500 celsius degree, creating a lava similar to the one of a vulcan. In the factory upper level it gets cold, it starts becoming similar to a ships wool. Pressed laterally and from the upper part, it becomes more similar to a mattress. Ready to be cut and to cover even quite small perimeters. The product during his lifetime is capable to generate a saving 300 / 1 the energy expense during his production. The similarity to the wool itself is impressive. Contrary to cloths, rock wool is an excellent performer in fire testing. Many materials used in buildings are in fact much worse. That does not mean there's no place for them in the market. So think about the role of insulation when you want to upgrade a building. When you want your house or factory to go up in the energy performance scale. Even if a passive, lack-of-loss of energy, is not enough to get the A position, as it requires the creation of energy. As we know the production of energy will be necessary in the future; and that's by anyone. As only it can bring to energy self sufficiency, that is the target to get before 2050.
