R Value Of Steel Siding

Corrugated metals is proud to announce a new addition to its product line the r panel.

R value of steel siding.

Most such r value tables ascribe an r value of r 0 87 for wood shingle siding. Siding wood bevel. Steel siding panels have a negligible r value so the hardiepanel would be marginally more energy efficient however probably not enough to make a difference in the entire assembly. R value table common building materials siding materials hardboard 1 2 0 34 plywood 5 8 0 77 3 4 0 93 wood bevel lapped 0 80 aluminum steel vinyl.

The u value is commonly called for in commercial construction. Plywood sheathing 1 2. That s a remarkable improvement and that will make a tangible difference in how much energy is saved in your home. The r panel is a durable energy efficient and time saving roofing material that can help you cut costs on your next project.

Fullback s brings the r value of steel siding to between 2 2. For instance while a brick veneer will only get you an r value of around 0 11 vinyl siding typically has a measurement of 0 61.

If the hardiepanel is applied over 7 16 osb oriented strand board the r value of the osb is 0 51.

It has an r value of 0 34 per 1 2 inch of thickness. As we said before the r value measures the thermal resistance of a material. Specifically here s how the different types stack up against one another. To compute a calculated u value simply add all the applicable r values of the construction assembly using the chart above and divide the total r into 1 0.

U values are computed from k or c or r factors. Non insulated aluminum steel or vinyl.
