Structure and Features of Each Type
The primary difference between unfaced and kraft faced fiberglass insulation lies in their design. This section explains their structural distinctions and how these impact their functionality.
- Unfaced Fiberglass Insulation: Unfaced insulation consists of fiberglass batts or rolls without any attached vapor barrier. It is ideal for spaces where moisture control is not a primary concern, such as interior walls or areas with existing vapor control systems.
- Kraft Faced Fiberglass Insulation: Kraft faced insulation features a layer of kraft paper on one side, acting as a vapor barrier. This facing prevents moisture from passing through the insulation, making it suitable for areas prone to humidity, like exterior walls or basements.
Applications and Best Use Cases
Each type of insulation is better suited for certain applications. This section highlights where and when each type should be used for maximum effectiveness.
- Unfaced Insulation Applications: Unfaced insulation is commonly used in interior walls, ceilings, and floors where moisture is not a concern. It is also an excellent choice for layering additional insulation over existing kraft faced insulation to increase the R-value.
- Kraft Faced Insulation Applications: Kraft faced fiberglass insulation is ideal for areas requiring moisture control, such as attics, basements, and crawl spaces. It is particularly useful in regions with high humidity or for exterior walls in colder climates to prevent condensation.
Moisture Control and Vapor Barrier Considerations
One of the biggest differences between unfaced and kraft faced insulation is the presence of a vapor barrier. This section delves deeper into how this impacts performance.
- Unfaced Insulation: Without a vapor barrier, unfaced insulation allows for better breathability. This reduces the risk of trapped moisture but requires proper ventilation in the space to avoid condensation issues.
- Kraft Faced Insulation: The kraft paper acts as a vapor barrier, preventing moisture from entering the wall cavity. However, improper installation, such as double barriers, can trap moisture and lead to mold or mildew.
Installation Differences
The installation process also varies between unfaced and kraft faced fiberglass insulation due to their structural differences. This section explains the key installation considerations.
- Unfaced Insulation Installation: Since there is no facing, unfaced insulation is typically held in place with support wires, netting, or friction fitting between studs.
- Kraft Faced Insulation Installation: The kraft paper includes flanges for stapling to studs or joists, making it easier to secure and align during installation. Proper placement of the vapor barrier is critical to ensure moisture control.
Cost and Availability
Cost can also play a role in choosing between these two types of insulation. This section compares their pricing and availability.

Differences between unfaced and kraft faced fiberglass insulation, you can select the option that best meets the specific requirements of your space. Whether prioritizing moisture control or ease of installation, each type offers unique advantages for creating an energy-efficient and comfortable environment.
FAQs about Kraft Faced Fiberglass Insulation
The main difference between kraft-faced and single-faced insulation is the type of facing material used. Kraft-faced insulation has a layer of kraft paper attached to one side, which serves as a vapor retarder. This type of insulation is commonly used in exterior walls and areas where moisture control is essential. Single-faced insulation, on the other hand, may have a different type of facing, such as foil, which is often used in radiant barrier applications. The choice between kraft-faced and single-faced insulation depends on the specific needs of the building. Kraft-facing is primarily used to manage moisture, while other facings may be selected for different benefits, such as reflective properties or additional protection from fire.
The R-value of kraft-faced batt insulation varies depending on the thickness and density of the insulation. Typically, the R-value ranges from R-11 to R-38, with higher values indicating better thermal resistance. For example, R-13 or R-15 insulation is commonly used in 2×4 wall cavities, while R-19 is more suitable for 2×6 walls or floors. In attics or areas that require more insulation, R-30 or R-38 kraft-faced batts may be used. The kraft-facing on the insulation doesn’t affect the R-value, as its primary purpose is moisture control rather than thermal resistance. When choosing the right R-value for your project, consider factors like climate, the specific location of the insulation, and local building code requirements.
In most cases, you do not need an additional vapor barrier when using kraft-faced insulation because the kraft paper itself functions as a vapor retarder. The kraft-facing prevents moisture from migrating through walls, ceilings, or floors, especially in colder climates where condensation is a concern. However, whether a vapor barrier is required depends on the local climate, building codes, and the specific area being insulated. In humid climates, it may be necessary to supplement kraft-faced insulation with a vapor barrier for added moisture protection. It’s always a good idea to check local building codes or consult a professional before installation to determine the best solution for your home’s insulation needs.
Kraft faced fiberglass insulation is a type of thermal insulation that combines fiberglass batting with a paper vapor retarder, usually made from asphalt-coated kraft paper. The “faced” aspect refers to this paper layer, which is attached to one side of the fiberglass batts. The kraft facing helps regulate moisture flow, preventing condensation from forming within the walls, ceilings, or floors of a building. It also aids in improving energy efficiency by reducing heat transfer and maintaining indoor temperatures. This type of insulation is commonly used in residential and commercial buildings for areas like walls, ceilings, attics, and basements. Its lightweight and flexible nature make it relatively easy to install. However, it is important to ensure proper placement of the facing to achieve the desired vapor control and thermal benefits. Always follow manufacturer guidelines for specific applications and climates.
Faced insulation should not be used in situations where a vapor barrier is not needed or could cause moisture-related problems. For example, in warmer and humid climates, installing kraft faced insulation on the wrong side of the wall assembly could trap moisture, leading to mold and rot. It is also unnecessary to use faced insulation in areas where an alternative vapor barrier, such as polyethylene sheeting or foam board insulation, is already present. Additionally, faced insulation is not ideal for soundproofing applications since the paper facing provides little benefit in reducing noise transmission. In multi-layered insulation systems, using faced insulation in both layers can create double vapor barriers, potentially causing moisture to become trapped. Always consult local building codes and consider the specific climate and application to determine whether faced or unfaced insulation is appropriate for your project.
The biggest problem with fiberglass insulation is its susceptibility to moisture and poor air sealing capabilities. When fiberglass insulation becomes wet, it loses its thermal effectiveness as water fills the air pockets that provide insulation. Even if it dries out, mold growth and odor can become ongoing issues. Fiberglass insulation also allows air to flow through it, which can lead to drafts and heat loss, especially in poorly sealed installations. Furthermore, improper installation—such as compressing the batts or leaving gaps—significantly reduces its performance. Another concern is that fiberglass particles can become airborne during installation or if disturbed, posing respiratory and skin irritation risks. While fiberglass insulation is widely used and cost-effective, it requires careful handling and proper installation to minimize these drawbacks and achieve optimal performance.
No, kraft faced insulation should not be left exposed in living spaces. The kraft paper facing is flammable and can pose a fire hazard if it comes into contact with sparks, open flames, or high heat sources. Building codes generally require that kraft faced insulation be covered with a fire-resistant material, such as drywall, to provide a barrier against potential ignition. However, in areas like attics or crawl spaces that are not regularly accessed, building codes may permit leaving it uncovered, but it is essential to verify local regulations. Even in these spaces, exposed insulation can degrade over time due to physical damage, UV light, or pests. For safety and long-term performance, covering the insulation with the appropriate material is strongly recommended.
It is generally not recommended to put plastic sheeting over kraft faced insulation. The kraft facing already acts as a vapor barrier, and adding another layer of plastic can create a “double vapor barrier.” This configuration can trap moisture between the layers, increasing the risk of mold, mildew, and wood rot. In most applications, the kraft facing provides sufficient moisture control when installed correctly. If additional moisture protection is needed, consult building codes and professionals to determine the best approach, which might involve alternative solutions like unfaced insulation combined with a properly placed vapor barrier. Always ensure that any vapor barrier is installed on the correct side (typically the warm-in-winter side) of the building envelope based on the local climate.
In most cases, a moisture barrier is not needed between insulation and drywall if the insulation already includes a vapor retarder, such as kraft facing. The facing serves as the moisture barrier when installed correctly, typically on the side facing the living space. Adding another moisture barrier between the insulation and drywall can create a double barrier, which may trap moisture and lead to mold or rot issues. However, in climates with high humidity or specific building designs, additional moisture protection may be required. For these scenarios, use unfaced insulation with a separate vapor barrier or consult local building codes and professionals for guidance. Proper ventilation and air sealing are also critical to managing moisture in wall assemblies effectively.
In most cases, it is not necessary to tape kraft faced insulation. The kraft paper vapor retarder is designed to overlap slightly, creating a functional seal when installed properly. Taping the seams can add an extra layer of moisture protection but is usually only recommended in areas with very high humidity or where a particularly tight vapor seal is needed. If you choose to tape the seams, use a tape specifically designed for vapor barriers to ensure a durable and airtight seal. Avoid using standard duct tape, as it may not adhere well to the kraft paper over time. Always follow manufacturer recommendations and local building codes to determine whether taping is necessary for your specific application.
Yes, kraft faced insulation is typically stapled to secure it in place. The kraft facing includes flanges, or tabs, that extend from the sides of the insulation batts. These flanges can be stapled to the edges of studs, joists, or rafters during installation. There are two common stapling methods: inset stapling (where the flanges are stapled inside the framing members) and face stapling (where the flanges are stapled over the front edges of the framing members). Both methods work, but inset stapling provides a cleaner finish and reduces the chance of air gaps. Proper stapling ensures that the insulation stays in place and that the vapor barrier functions effectively. Make sure to avoid over-compressing the insulation during installation, as this can reduce its thermal performance.
Yes, faced insulation typically needs to be covered with a fire-resistant material, such as drywall, for safety reasons. The kraft paper facing is flammable and can pose a fire hazard if left exposed in living spaces. Building codes generally require that any exposed kraft faced insulation be covered to protect occupants. However, in certain non-living spaces, such as attics or crawl spaces, local codes may allow the insulation to remain uncovered. Even in these cases, covering the insulation can protect it from physical damage, pests, and UV degradation. Always check local building codes and safety requirements to ensure compliance for your specific application.
The paper on faced insulation should face the warm side of the building, which is typically the interior living space in most climates. This placement ensures that the kraft facing functions effectively as a vapor retarder, helping to prevent moisture from passing into the insulation and condensing within the wall cavity. In colder climates, this means the paper faces inward toward the heated area. In hotter climates where air conditioning is used extensively, the orientation may differ; consult local building codes and climate-specific guidelines. Correct placement is crucial for both moisture control and thermal performance, so always verify installation instructions for your specific insulation product and application.
To install kraft faced insulation, start by measuring and cutting the insulation batts to fit the space between wall studs, ceiling joists, or floor beams. The kraft paper should face the warm side of the space (inward for colder climates, outward for hot climates). Fit the batts snugly without compressing them, as compression reduces thermal performance. Use the paper flanges for stapling, either to the inside edges of the framing (inset stapling) or over the front edges (face stapling). Ensure there are no gaps or folds that could compromise the insulation’s effectiveness. Overlap seams slightly and secure with staples every 6-8 inches. Avoid blocking vents or obstructing electrical wiring. If additional protection is needed, such as in living spaces, cover the insulation with drywall or other fire-resistant materials, as the kraft paper is flammable. Always follow local building codes and manufacturer instructions.
Fiberglass insulation generally lasts 50 to 100 years under ideal conditions, making it one of the most durable types of insulation. However, its lifespan can be significantly reduced by factors such as moisture, mold, pests, and physical damage. If fiberglass insulation becomes wet, it can lose its insulating properties and may develop mold if not dried promptly. Settling or compression over time can also reduce its effectiveness, especially in attics or areas with heavy use. Regular inspections are recommended to ensure the insulation remains intact and performing well. If signs of damage, sagging, or moisture appear, it may need to be replaced earlier. Proper installation, ventilation, and maintenance are critical to maximizing the lifespan of fiberglass insulation, including kraft faced varieties.
Removing the kraft face from insulation requires care to avoid damaging the fiberglass material. Lay the insulation flat on a clean surface. Using a utility knife, carefully score along the edge where the kraft facing meets the fiberglass. Gently peel back the paper, working slowly to prevent tearing the fiberglass batts. If the adhesive holding the paper is strong, use a putty knife or scraper to assist in separating the layers. Wear protective gear, such as gloves, a mask, and safety glasses, to avoid skin irritation and inhalation of fiberglass particles. Disposing of the removed kraft paper should be done according to local waste disposal guidelines. This process is often needed when repurposing or modifying insulation for applications where a vapor barrier is not required.
Yes, faced insulation can be a fire hazard if left exposed. The kraft paper facing is flammable and can ignite when exposed to heat, sparks, or open flames. This is why building codes typically require that faced insulation be covered with a fire-resistant material, such as drywall, in living spaces. In areas like attics or crawl spaces, it may be permissible to leave it uncovered, but the insulation is still at risk of fire if exposed to heat sources. For enhanced safety, some kraft faced insulation products come with fire-retardant treatments, but even these should not remain exposed in most applications. Always follow local building codes and safety recommendations to mitigate fire risks.
Fiberglass is not as hazardous as asbestos, but it can pose health risks if proper precautions are not taken. Unlike asbestos, which is a known carcinogen that can cause diseases like mesothelioma and lung cancer, fiberglass is generally considered less harmful. However, inhaling fiberglass particles can cause irritation to the respiratory system, throat, and skin. Long-term exposure to high levels of airborne fiberglass dust may have potential health risks, though evidence linking it to cancer is limited. Proper handling, including wearing gloves, masks, and protective clothing, minimizes exposure to fiberglass fibers. Modern fiberglass products are designed to be safer, with advancements in manufacturing reducing the potential for fiber release. Always follow safety guidelines when handling fiberglass insulation.
Yes, compressing fiberglass insulation is bad because it reduces its insulating effectiveness. The thermal resistance (R-value) of fiberglass insulation depends on the air pockets within the material that trap heat. When compressed, these air pockets are diminished, lowering the R-value and reducing the insulation’s ability to resist heat flow. For example, compressing a 6-inch batt designed for a specific cavity into a 4-inch space will not provide the intended level of thermal protection. Proper installation without compression is essential for maximizing the insulation’s performance. Always choose the correct thickness of insulation for the intended space and avoid overpacking or forcing it into areas that are too small.
No, it is not safe to have exposed fiberglass insulation in living spaces. Fiberglass particles can become airborne if the insulation is disturbed, potentially causing respiratory irritation, skin itching, and eye discomfort. Prolonged exposure to airborne fiberglass particles may pose health risks. Additionally, kraft faced insulation has a flammable paper layer that increases fire hazards when exposed. To ensure safety, fiberglass insulation should be covered with a fire-resistant material, such as drywall, especially in areas where people spend time. In non-living spaces, like attics, it may remain uncovered if undisturbed, but caution should still be exercised when accessing these areas.
Yes, there are alternatives to fiberglass insulation that may be better for certain applications. Spray foam insulation offers superior air sealing and higher R-values per inch, making it ideal for reducing energy loss in hard-to-reach areas. Mineral wool insulation is fire-resistant, water-repellent, and provides excellent soundproofing. Cellulose insulation, made from recycled paper, is environmentally friendly and effective for thermal and sound insulation. Reflective insulation is suitable for hot climates where radiant heat barriers are needed. Each type has its advantages and disadvantages, depending on the application, budget, and climate. While fiberglass remains a popular choice for its affordability and ease of installation, these alternatives may offer enhanced performance in specific scenarios.
Yellow and pink insulation are functionally equivalent in performance, as their color differences are due to the manufacturing processes or the brands producing them. Pink insulation is often associated with Owens Corning, which uses a trademarked dye. Yellow insulation is commonly made by other manufacturers, such as Johns Manville. Both types offer similar thermal resistance (R-value), fire safety, and moisture resistance, assuming they are of the same grade and thickness. When choosing insulation, focus on the R-value, ease of installation, and suitability for your project rather than the color. Both yellow and pink fiberglass insulation meet industry standards for performance.
No, a vapor barrier should not be on both sides of insulation. Installing vapor barriers on both sides can trap moisture within the wall cavity, leading to mold, mildew, and structural damage. A vapor barrier should typically be installed on the warm-in-winter side of the insulation. In colder climates, this means placing it on the interior-facing side, while in hot, humid climates, it may be placed on the exterior-facing side. The specific placement depends on local climate conditions and building codes. Consult a professional or follow manufacturer recommendations to avoid creating moisture-related issues.
The life expectancy of fiberglass insulation ranges from 50 to 100 years under ideal conditions. It remains effective as long as it stays dry, intact, and free from significant physical or pest damage. Factors such as water exposure, compression, and improper installation can reduce its lifespan. Regular inspections can help identify issues early, ensuring the insulation continues to perform well. Proper ventilation, vapor barriers, and maintenance can extend its effectiveness, making fiberglass insulation a durable and reliable option for long-term use.
The most common type of fiberglass insulation is batt insulation with a kraft paper facing. These batts are pre-cut to standard sizes for easy installation between wall studs, ceiling joists, or floor beams. Kraft faced batts are popular because they combine thermal resistance with a built-in vapor barrier, simplifying installation in residential and commercial applications. Loose-fill fiberglass insulation is another widely used form, typically blown into attics or hard-to-reach spaces. Both types are valued for their affordability, ease of use, and energy-saving properties.
Kraft faced insulation is best used in areas where thermal resistance and moisture control are needed, such as walls, ceilings, floors, and attics. It is particularly effective in exterior walls, where the kraft paper serves as a vapor barrier to prevent moisture from entering the wall cavity. It is also suitable for basements and crawl spaces, provided the paper facing is correctly oriented and local building codes are followed. Avoid using kraft faced insulation in areas where a separate vapor barrier is already present, as this can lead to moisture buildup. Always install it with the kraft paper facing the warm side of the space.
