Customer Questions & Answers
-
Question:
What is the insulation value of R 38 fiberglass?
Answer: The R 38 fiberglass insulation provides a thermal resistance value of R 38, which is ideal for attics. This means it effectively reduces heat transfer, keeping your home warmer in winter and cooler in summer. Higher R-values indicate better insulating performance, particularly beneficial in extreme climates. This product is well-suited for areas where high energy efficiency is a priority, such as in attics with less ventilation, helping you save on energy costs. -
Question:
How is the insulation packaged and how much area does it cover?
Answer: The insulation comes in 8 bags, with a total coverage of 469 square feet. Each bag contains pre-cut panels measuring 16 by 48 inches, making installation straightforward. This configuration is designed to fit standard joist spacings, specifically 2x12 wood beams. It's perfect for DIY projects or professional installations, providing a significant coverage area that can effectively insulate large attic spaces. -
Question:
Is the Kraft facing on the fiberglass insulation important?
Answer: Yes, the Kraft facing serves as a vapor barrier, which helps prevent moisture from penetrating the insulation. This is crucial in attics where humidity can lead to mold and mildew growth. Additionally, the Kraft paper enhances the insulation's ability to regulate temperature and humidity levels, improving overall energy efficiency in your home. It's particularly beneficial in colder climates where moisture management is critical. -
Question:
Can this fiberglass insulation be installed in existing attics?
Answer: Absolutely! This R 38 fiberglass insulation can be easily installed in existing attics, providing a retrofitting option for enhancing thermal efficiency. When adding insulation to an existing attic, it's important to ensure that spaces are properly ventilated and there are no air leaks that could compromise performance. Many homeowners choose this option to improve their home's energy efficiency and comfort levels. -
Question:
What is the recommended installation method for R 38 fiberglass insulation?
Answer: The recommended installation method for R 38 fiberglass insulation involves placing it between the attic joists and ensuring a snug fit. It's best to use protective gear, such as gloves and masks, while handling fiberglass. This insulation type should be installed with the Kraft facing up towards the living space to act as a vapor barrier. Following manufacturer guidelines during installation ensures maximum effectiveness and longevity. -
Question:
Is this insulation fire-resistant?
Answer: Yes, fiberglass insulation, including R 38 Kraft Faced products, is inherently non-combustible, meaning it doesn't support combustion. This property makes it a safe choice for areas like attics near electrical wiring or other potential heat sources. While it provides excellent thermal insulation, it’s crucial to comply with local building codes regarding fire safety and installation to ensure your home remains safe. -
Question:
How do I know if R 38 insulation is suitable for my climate?
Answer: R 38 insulation is suitable for regions with colder climates or areas that experience significant temperature fluctuations. If you live in a climate where the average winter temperature is low, opting for a higher R-value like R 38 is ideal for maximizing energy efficiency. Consider consulting local building codes or a professional to assess your unique climate needs before making a decision. -
Question:
Can I use this insulation in walls instead of attics?
Answer: While the R 38 fiberglass insulation is primarily designed for attics, it can be used in walls if space allows, particularly in exterior walls where higher insulation values are beneficial. However, it’s essential to ensure adequate ventilation and comply with local building codes. Using it in walls can enhance energy efficiency and overall comfort in your living spaces. -
Question:
How do I compare R 38 insulation with other R-values?
Answer: Comparing R 38 insulation to other R-values involves understanding that higher numbers indicate more effective thermal resistance. For example, R 19 is adequate for moderate climates, while R 38 is better for colder areas, offering superior energy savings. By assessing your climate needs and desired comfort level, you can determine the most suitable R-value for your home, prioritizing energy efficiency. -
Question:
Where can I buy 469 SQFT 8 Bags of R 38 Kraft Faced 16 by 48 Fiberglass Fits 2X12 attic?
