2022年10月5日 · R38 insulation is required in ceilings in hotter regions and floors in colder regions. The thinnest insulation layer achieving the R38 rating is with closed cell spray foam polyurethane (5.38-7.6") and the thickest insulation layer achieving the R38 rating is with loose-fill fiberglass (15.7").

2023年9月7日 · R38 insulation has an R-value of 38, which is a measure of its thermal resistance. Using R38 insulation can reduce thermal conductivity by 97 percent. The thickness of R38 insulation ranges from 5.38 inches to 15.7 inches, with closed-cell spray foam requiring the thinnest and blown-in fiberglass requiring the thickest.

2010年4月19日 · The thickness of your R-38 insulation will depend on the material you have, the brand, and how it's installed. The fiberglass comes in rolls, also known as batts, which vary in size. An R-38 fiberglass batt should be approximately 12 inches thick, while the thickness of cellulose insulation of a finished, fitted product will larger.

Owens CorningTM R-38C EcoTouch® Thermal Batt insulation is designed to provide maximum thermal performance for cathedral ceiling applications. R-38C EcoTouch® Thermal Batt insulation is available unfaced or with a kraft vapor retarder.

Owens Corning PINK Next Gen Fiberglas insulation installs faster because it’s made like no other fiberglass insulation. PINK Next Gen fiberglass insulation batts recover instantly, cut and split cleanly, glide in easily and stay put in the cavity, helping deliver inspection-ready results faster.

2024年11月4日 · Comparing R-30 and R-38 insulation highlights the key differences in thermal resistance, thickness, and suitability for various climates. This comprehensive analysis will help you determine which insulation type best suits your project’s requirements, to ensure energy savings and compliance with building codes.

2023年9月17日 · R30 insulation has a thickness of about 9.5 to 12 inches, while R38 insulation is around 12 to 15 inches thick. The difference in thickness directly affects the insulation’s ability to resist heat flow. With a thicker layer of insulation, R38 provides better insulation performance compared to R30.

2024年10月28日 · Achieving the recommended thickness for R38 blown insulation, typically around 12-14 inches, is crucial for enhancing energy efficiency, reducing utility bills, and creating a comfortable indoor environment throughout the year.

2024年10月28日 · R38 insulation refers to the thickness of the insulation material required to achieve an R-value of 38, with specific measurements varying depending on the insulation material used. There are several factors to consider when choosing R38 insulation, including climate, building design, energy efficiency goals, building codes, and budget.
