R-value evaluates how well insulation prevents heat transfer. You may have heard this word if you want to renovate your home with vinyl siding. CMB East Brunswick Stucco & EIFS can assist you in comprehending vinyl siding R-value and exterior home options.

R-Value

Proper interior and external insulation reduce air leaks. R-value measures heat resistance. It’s based on the R-factor, which measures heat flow between two plates. These lab experiments use one square foot of 1-inch-thick material. The material’s surfaces are 1°F cooler. Thermal conductivity is measured in BTUs per hour.

R-value is R-factor times the material thickness. If a material’s R-factor is two and its thickness is 1.5 inches, its R-value is 3. The greater the R-value, the better the material prevents heat from escaping and keeps cold air out.

Inside Insulation

Most people visualize fiberglass or spray foam insulation in the walls. This insulation is effective, but air loss can increase heating and cooling expenditures. Although your wall studs may be insulated, the studs themselves aren’t. 25% of a home’s wall space is studded. Thermal bridging transfers warm interior energy to the cold exterior. These energy leaks could cost you and prohibit your home from being generous.

Insulated Vinyl Siding

Insulated vinyl siding covers studs and other areas to prevent energy loss and thermal bridging. Depending on brand, kind, and size, good quality insulated vinyl siding has an R-value of 2.0 – 4.0.

The vinyl siding R-value is 0.61. Whether insulated or not, premium vinyl siding has a high R-value. Other materials with R-values include:

Fiber cement – 0.37

Stucco – 0.40

Brick veneer –0.44

Stone veneer – 0.11

A contractor can help you understand the R-value and choose the best material based on your demands and desired look.

Vinyl Siding Benefits

Both conventional and insulated vinyl siding has a greater R-value, which can boost your home’s energy efficiency. Vinyl siding is low-maintenance and easy to clean with basic detergent and a garden hose.

Quality vinyl siding resists UV radiation, high winds, and snowstorms. 

It’s pest- and moisture-resistant, preventing decay. Vinyl siding comes in every color, texture, and style imaginable, including wood and stone appearances.

First impressions are just as significant as the R-value and energy efficiency. Installing vinyl siding provides curb appeal and can raise the value of your property, whether you’re selling it or not.
