Depending on the type of fiberglass insulation you use, the R-value can range from 2.2–4.3 per inch. Insulation's R-value indicates how efficient it is. The higher the number, the more effective the insulation.
R-values rate how well building insulation can prevent the flow of heat into and out of the home. Higher ratings mean greater insulation performance and thus more savings on your next heating and cooling bill. This guide will teach you what you need to know about insulation R-values so you can better insulate your home. SHOP INSULATION NOW
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.
The range of R-values of insulation materials spans from materials with R-10 insulation values per inch like vacuum insulated panels and silica aerosol to below R-1 values per inch like bricks, glass, and poured concrete.
The R-value of batt and rolled fiberglass insulation varies a little by manufacturer. Typically it is in the range of 2.9 to 3.8 per inch. Summarized below is a table that will enable you to quickly compare batt and rolled fiberglass insulation R-values with corresponding thicknesses.
R-value chart gives R-values for commercial and residential insulation and roofing products. Use this table to calculate roof R-value or RSI value.
This guide will explore the ins and outs of insulation R-value, helping you choose the right insulation for your home’s needs and potentially saving money on your energy bills in the long run. What Is R-Value and Why Does It Matter? R-value is a numerical measure of an insulation material’s ability to resist heat flow.
Insulation R values of various materials: Here we provide extensive Tables of Insulation Values and Properties for Various Insulation & Building Materials or other substances useful in procedures to measure or calculate heat loss in a building.
To determine the appropriate insulation thickness to install, divide the recommended R-value by the R-value per inch of your chosen insulation material. For instance, in a moderate climate aiming for R-49, you would need about 16-22 inches of blown fiberglass insulation.
Here’s the R-value insulation chart you’re looking for, but before you choose a product strictly on thermal resistance, read on. This chart shows the approximate R-value per inch of various insulating materials but does not take into account any air leakage that can dramatically affect overall performance.
