# What is the R value of a 10 inch log?

**10**-

**inch**milled

**log**has an

**R**-

**value**of 10.7 which is equivalent to a 2×4 stud wall with 31⁄2

**inches**of fiberglass with an 8-

**inch**stud spacing. Natural

**logs**are tapered so the

**insulation value**should be based on the average thickness.

Similarly one may ask, what is the R value of a log?

A material's thermal resistance or resistance to heat flow is measured by its R-value. In a solid log wall, the logs provide both structure and insulation. The R-value for **wood** ranges between **1.41 per inch** (2.54 cm) for most softwoods and 0.71 for most hardwoods.

Similarly, are log cabin homes energy efficient? A **log** home's **energy efficiency** is based on the wood's insulation properties and its thermal mass. Testing has shown that **log homes** often are more **energy efficient** than conventional **homes** boasting higher R-values.

Likewise, are logs good insulators?

The higher the R-Value is, the better insulating the wood. Softwoods like cedar, pine and fir provide better **insulation** than hardwood. **Logs** are able to store heat throughout the day and release it through the cooler night, requiring less energy to heat your home and creating a very warm and cozy feeling at night.

What is the R value of an air gap?

For an **air gap** to improve the thermal performance of a building element, it requires the addition of a low emittance surface (shiny aluminium foil) to one or both sides of the **air gap**. Without the addition of the foil surfaces, the **R**-**Value** of the non reflective **air gap** is small (R0.
