Difference between Joist and Rafter Roof Insulation

As you consider getting new insulation installation done in your home, it becomes mandatory to take note of the several considerations. The most crucial of them all is what you actually want to do with several areas like attic, etc. As far as the attic usage is concerned, you’ll basically have two options to go with. One is using it as a living area, while the other is leaving it unused. In case, you are looking to use it, it would be important that you get the roof insulated and also the rafters.

In case, you have no plans to implement plan#1, you should consider getting only the walls insulated or the joist level only. The reason why experts from roofing companies suggest this is that this will increase the heat through the un-insulated area and this would be a complete waste of not just heat, but also efforts as well as the money.
