When you build the new house or buy the ready-made house, you have to aware of many factors for this decision like material, price, location, worker and other items etc. Some of you may ignore the little part of your house that’s housing insulation.

I’m thinking about this part because most of houses that were built before around 1975 don’t use insulation. So, for today, I’m not only suggesting for the new house owner but also for the person who just knew that your lovely house doesn’t use it.
