New households that are being built today are pursuing fairly strict energy efficiency standards. Of course, this is not the case for older houses. The best way to make an older home significantly more energy efficient is to use insulation. This isn't easy to do with the external side walls, but can be done easily with blown-in insulation in the attic. This will certainly make your house warmer during the cold months, and also cooler in the summer. If you live in a really old house, you may just have newspapers in your wall for insulation.

woodworking tips These days, with all of the ecological concerns, insulation has developed into a discipline all by itself. Insulating materials receive an R-value, and this value must be used to determine the amount of insulation needed, depending on the area of the country you live. For example, colder regions need to have insulation with a higher R-value than places that dont get terribly cold. A good choice to minimize heating expenses is blown-in insulation. There are many advantages of using blown-in insulation instead of fiberglass insulation rolls, like installation, energy efficiency in addition to where it can be used.

Of the top five reasons for utilizing blown-in insulation, the first is that it is adjustable. You may easily control the actual R-value for insulation by adjusting the amount of insulation you use. When you have to have an R-value of 15, you just simply blow a certain volume of insulation, in the event that you need a higher R-value, just add more insulation woodworking plans. Another reason that blown-in insulation would be the way to go is that the materials are typically virgin so there's less chance of allergies. Yet another valid reason is that blown-in insulation can create a tighter seal since it can easily fill cracks and pockets of void space. The system is rapid, and given that everything is filled in, it is very energy-efficient.

Applying blown-in insulation is easy for a newly framed house. All that is done is staple a netting over the outer wall studs, then cut some little holes, stick in the hose, and load up the wall cavity. The insulating material will stick to the studs and fill up every one of the empty spaces. All you need to do next is to cover the walls with vapor barrier and drywall, then you are done. To blow in the ceiling insulating material, you drywall the ceiling first, then ascend into the attic area and blow it in. Its more difficult with older homes considering that the wall covering will need to be removed. Following the removal of the wall covering the procedure is just the same. woodworking plans When you have an extremely old house, with no insulation, you can just cut a hole in the wall, and blow it in, then cover up the hole.

While the preliminary cost is high, it will pay itself in the long run. With lower energy charges and a warmer home, using blown-in insulation makes the most sense.
