Oct 5, 2022 · Using the right insulation thickness for your project and climate is crucial if you want a significant increase in your energy savings. R38 insulation is required in ceilings in hotter regions and floors in colder regions.

Sep 7, 2023 · 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.

Feb 8, 2018 · Owens Corning R-30 and R38 batts are full 16” or 24” widths meaning they will push together over the framing to provide full R-value for the entire attic, minus the small loss for the wood framing itself.

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.

R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home. Learn how to take action today and Rule Your Attic! with ENERGY STAR.

Nov 4, 2024 · 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.
