Modern properties tend to be insulated under the concrete floor; however, suspended traditional floors can also be insulated. Whether you want faced vs unfaced insulation may depend on which particular area of your home needs insulating. The idea is to ensure that when it is used, for example, to insulate drywall, it ensures that both the insulation and the drywall stay dry for years to come.
Choosing the right faced insulation can be difficult with the several options available on the market. Reflective attic insulation is used most commonly in attics to reduce the costs of cooling a home in the summer.
They are often made with a reflective aluminum foil that radiates heat from the sun away from inside the building. However, per square meter, they tend to be more expensive to install. Some unfaced materials, such as blown in insulation , are designed to protect against moisture without any additional layers.
It is sold in rolls, can be easily installed, and is among the cheaper options to insulate your home. Foam insulation, which is often used to insulate walls, is among the easiest to install as it is sprayed or injected into place with a machine, allowing you to fill tight spaces with ease.
Over the years, advances have been made as different types of insulation that homeowners use. You might know that faced insulation is the most popular, but is that the right choice for you? You might find instead that unfaced insulation would work better with your particular home. Faced just means that kraft paper is attached to the insulation itself. In reality, think of choosing the right insulation for your home the same way you would buy gas for your car.
There are different types of fuel that perform differently, but all can be used to power your car. The list can go on and on. But, we at JM welcome any questions you may have about insulation and always want you to be informed. We recently received this question about the unfaced insulation:.
Can the Kraft-faced be removed easily? The exterior walls are stucco and they need some air circulation to allow moisture to dissipate. Unfaced means the insulation lacks a vapor retarder paper or plastic facing. Unfaced insulation is great for new construction, remodels, walls, floors, ceilings, basements, attics and crawlspaces.
One particular note: Unfaced as well as Kraft-faced insulation should always be cut to fit with a utility knife and never folded over for the best performance. Kraft-faced insulation includes a paper vapor retarder, which helps prevent mold and mildew. Kraft-faced insulation should be installed in exterior walls, exterior basement walls, and attic ceilings by pressing the product into the wall cavity with the paper side facing outward, towards the installer.
To better understand the difference between the faced and unfaced insulations, it is best to understand what is being insulated and its importance. A facing insulator comes in various paper or plastic materials, e. Insulating material comes in rolls that are commonly referred to as batts. There are two varieties of batt insulations:.
Faced Insulation is a type of roll or batt insulation with a kraft paper attached to one side which acts as a vapor barrier. The faced should always be against the drywall as the drywall will be the interior side. They are ideal for spaces that have never been insulated before, such as in vaulted ceilings, exterior walls, and exterior basement walls. For example, when insulating a ceiling , the paper side should face down and not up. When insulating an exterior wall, the paper side will be to the interior with the drywall installed against the paper.
Faced insulation should be used in areas where no insulation is present. Do not install faced insulation over existing insulation. When installing faced insulation, the paper side is always installed against the living space. Unfaced Insulations are made from fiberglass roll or batt insulation products and have no kraft paper attached to them.
Unfaced insulation is held into place by the pressure or friction fit in joints and rafters when installing it. Unfaced insulations are also ideal for backing up areas that have been insulated before and probably need reinforcement.
They are also the best soundproof insulation around for indoor walls such as the nursery. R-value is used to determine the air resistance offered by an insulation product.
