FAQs about Plastic Faced Fiberglass Blanket Insulation
Fiberglass insulation, whether used in walls, attics, or other spaces, can be covered with plastic, but this depends on the specific requirements of your project. When it comes to plastic faced fiberglass blanket insulation, the plastic layer serves as an essential vapor barrier, which prevents moisture from infiltrating the insulation and helps maintain its thermal efficiency. In many cases, this pre-existing plastic facing eliminates the need for additional plastic covering.
However, in situations where you’re using unfaced fiberglass insulation, adding a plastic vapor barrier might be necessary, especially in areas prone to moisture buildup, like basements or crawl spaces. By covering the insulation with plastic, you can help prevent mold growth, protect the material from moisture damage, and ensure the insulation’s long-term performance. It’s important to note that the placement of the plastic barrier should be on the warm side of the insulation (facing the living space), as this helps prevent condensation within the insulation material.
Faced fiberglass insulation typically includes a built-in vapor barrier as part of the facing material (usually plastic or kraft paper). This vapor barrier helps to control moisture migration, which can otherwise compromise the performance of the insulation and create conditions for mold growth or water damage. In the case of plastic faced fiberglass blanket insulation, the plastic layer acts as a protective barrier to prevent moisture from entering the insulation from areas like basements, attics, or exterior walls.
Because faced fiberglass insulation already incorporates a vapor barrier, additional vapor barriers are not generally necessary unless the building or space has specific conditions that require extra moisture protection. For instance, in very humid environments or spaces where there’s heavy water vapor, you may still consider adding a secondary vapor barrier for enhanced protection.
However, if you’re using unfaced fiberglass insulation (which doesn’t include a vapor barrier), you will need to install a separate vapor barrier to prevent moisture from seeping through and reducing the insulation’s effectiveness.
To sum up, faced fiberglass insulation already comes with a vapor barrier, and in most cases, additional layers are not required unless special moisture conditions exist.
Blanket insulation, particularly fiberglass blanket insulation, offers a range of benefits, including thermal resistance, soundproofing, and affordability. However, like any material, it does come with some potential disadvantages that you should consider:
Installation Challenges: While fiberglass blanket insulation is easy to cut and fit into most spaces, it can be a bit difficult to handle, especially in tight or irregular spaces. You need to take care when handling fiberglass insulation to avoid irritation from the glass fibers, which can cause skin and eye discomfort. The insulation may also need to be secured properly to prevent gaps that could compromise its performance.
Moisture Sensitivity: Fiberglass insulation can lose its effectiveness if exposed to moisture. In environments where humidity is high or water leaks are possible (such as basements or crawl spaces), fiberglass insulation may absorb moisture, reducing its R-value (insulation efficiency) and providing a breeding ground for mold. This is why plastic faced fiberglass blanket insulation, which includes a vapor barrier, is often preferred in such environments.
Limited Air Barrier: While blanket insulation excels in providing thermal resistance, it doesn’t always prevent air leakage unless it is carefully sealed. Gaps or holes in the insulation can lead to drafts, reducing its energy efficiency. This is why additional sealing and proper installation practices are important.
Plastic wrapped insulation typically refers to insulation materials that are covered in a plastic or polyethylene film to provide an additional layer of protection, usually in the form of a vapor barrier. The plastic wrap serves a critical function in controlling moisture by preventing water vapor from entering the insulation, which can otherwise compromise its performance and lead to mold, mildew, or structural damage.
This type of insulation is commonly known as plastic faced fiberglass blanket insulation or plastic faced insulation, where the plastic layer is used to encase fiberglass or other insulation materials. The plastic wrap is typically a polyethylene film, which is durable and resistant to moisture. In some cases, the plastic can be combined with a reflective coating for enhanced thermal efficiency.
Plastic wrapped insulation is widely used in environments where moisture resistance is essential, such as basements, attics, metal buildings, and crawl spaces.
