it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.

The value of R is 6.8. This is in half inch rigid form.

Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8

The R-value of insulating material is an indication of its effectiveness in reducing heat flow through walls, floor, and ceiling of a structure.

The answer depends on what you mean by "r values".

The R-value is a valuation of how well-insulated the garage door is. The higher the R-value, the better insulated it is, but when comparing it is wise to learn if the given rating is based on the entire door or only certain portions.

No. r equals 12 is a serious calculation error. The absolute value of r cannot be greater than 1.No. r equals 12 is a serious calculation error. The absolute value of r cannot be greater than 1.No. r equals 12 is a serious calculation error. The absolute value of r cannot be greater than 1.No. r equals 12 is a serious calculation error. The absolute value of r cannot be greater than 1.

Insulation is rated in terms of thermal resistance, called R-value, which indicates the resistance to heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value of thermal insulation depends on the type of material, its thickness, and its density. In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added.
