subject: Green Home Insulation – Not All Good [print this page] The new decade's building trend will undoubtedly revolve around green building and eco friendly homes. All the reasons are there: a healthier living environment, less damage to our eco system and huge cost savings. But when setting to get a greener, healthier home, it is important to know what to avoid. Green home insulation is known for its benefits: keeping your house cool during the hot season without cracking up the AC or keeping warm at winter and not getting a huge electricity bill are great benefits, so naturally every planner and contractor will recommend it. But when going with insulation, you also run the risk of negatively effecting your living environment. When you are breathing within a well insulated space, the levels of CO2 rise. Effecting your ability to concentrate and making you feel tired. Headaches as well as eye, nose and throat irritations might also be a result of well insulated, poorly ventilated green home. It was found that a whopping 24% of people of thought they were coming down with flu, actually suffered from CO2 poisoning. The solution could be opening a window, but during the winter, cold weather might make us decide against that. Some people do decide to open the windows even in the middle of winter to avoid rising levels of CO2, but most don't. The solution is a fresh air system that removes CO2 and keeps the level of fresh, outside oxygen high. Such a system is not expensive and it can balance out the negative effect that an excellent green home insulation system has on our health.
