Rafter insulation is something that is necessary within your home. You will find that an attic is something that needs to be insulated just like the rest of your home.

Attic rafter insulation is something that is not very difficult to do and will end up saving you a lot of money and trouble in the long run.

You will be able to find this type of insulation at most places that you can find regular insulation. It is important that you are able to get the kind that goes for rafters so that you will not have a lot of insulation cuts that you have to make and not too much will be wasted.

2. R Value
The R value for insulation basically means how much insulation it can ultimately provide. You will need to make sure that the R value is one that you feel comfortable with. Typically, whenever you are getting insulation for your attic rafters, something between R-30 and R-60 is the best way to go. However, if you have a larger attic or home or live in an area that has severe winters, then you may want to consider getting a higher R value. For mild winters and smaller homes, a smaller R value may be necessary.

It is a good idea to have your staples laid out about every 6 to 8 inches along each piece that you lay.
