The attic is one of the largest sources of potential heat loss in a home and often one of the most neglected areas when it comes to insulation, especially in older homes. That's why adequate insulation is so important. Without proper attic insulation, your energy bills could be significantly higher. Whether your attic is and will remain unfinished, be used for storage, or be finished for use as living space, make sure that it is properly insulated with the right amount and kind of insulation.
If your attic is unfinished and you’re insulating it for the first time, you will install insulation in the floor joists. If you’re building a new home, install ceiling insulation up from underneath, before you put in drywall.You can also insulate your unfinished attic with blow-in insulation.
An exterior wall is any wall that faces outside or otherwise separates conditioned spaces from unconditioned spaces, such as knee walls and basement walls. These walls should be thoroughly insulated in order to create the all-important thermal envelope around your living space. Properly insulated exterior walls make all the difference between a comfortable, energy-efficient home and a drafty one.
An interior wall is any wall that does not face outside. You may think that such walls do not require insulation. However, interior wall insulation adds significantly to the enjoyment of peace, privacy and comfort in your home by keeping sound from migrating from one room to another. Interior wall insulation also contributes to your home's overall energy efficiency.
Ceiling insulation provides essential sound control between floors in your home. Properly insulating the ceilings will make your home a more peaceful and quiet place because it will ensure that footsteps and other sounds do not migrate to other rooms.
When ceiling insulation is installed at the same time as wall insulation, which is usually the case in new construction, it is installed up from underneath, before drywall is put in.
Underfloor means the floor above an unheated crawl space or basement. Once the underfloors are properly insulated, you will increase the overall comfort of your home because underfloor insulation provides valuable sound control and thermal control.
