If you’re planning to insulate your home, understanding what R-value means for your home insulation is essential. This number plays a major role in your home’s energy efficiency, comfort, and overall heating and cooling costs.
At Mountain View Insulation, LLC, we help homeowners throughout Tacoma, WA, choose the right insulation materials and R-values for their specific needs. In this guide, we’ll break down R-value ratings, why they matter, and how to use them to make smarter insulation decisions.
What Is R-Value? R-Value Explained Clearly
R-value measures how well insulation resists heat flow. The higher the R-value, the better the material insulates. It’s one of the most important numbers to consider when insulating your attic, walls, or crawlspace.
We go beyond the basics of R-value explained to help you understand how climate, home size, and material type all impact which R-value is right for your project. Learn more about our insulation services in Tacoma, WA to see how we tailor each job to your home.
Attic R-Value and Why It Matters Most
Your attic is where insulation matters most. Heat rises, and a poorly insulated attic can lead to massive energy loss. The recommended attic R-value in colder climates is between R-38 and R-60. In the Tacoma area, this range keeps homes warm in winter and cool in summer without overworking HVAC systems.
Whether you’re upgrading blown-in insulation or starting from scratch, we’ll recommend the right R-value and material for maximum comfort and efficiency.
Spray Foam and Cellulose R-Value Considerations
Each insulation type offers different thermal resistance. For example, spray foam R-value typically ranges from R-6 to R-7 per inch, making it a top performer in tight spaces. It’s ideal for sealing gaps and improving air quality while offering high insulation value.
On the other hand, cellulose R-value in Tacoma tends to average R-3.2 to R-3.8 per inch. It’s eco-friendly and performs well when installed properly, especially in wall cavities and attics.
Insulation Ratings and Thickness: What You Need to Know
Choosing insulation isn’t just about the material—it’s also about insulation ratings and thickness. Even high R-value materials underperform if not installed with the right depth or coverage. That’s why we focus on both R-value and application method to ensure full performance.
R-value is cumulative, meaning thicker applications result in higher overall resistance. Understanding the balance between space and performance is key when selecting insulation for walls, attics, or basements.
