Imagine three diagrams, each representing a cross-section of a different insulated siding type.
Vinyl Insulated Siding: The diagram shows a thin layer of vinyl on the outer surface. Directly beneath is a layer of foam insulation, typically expanded polystyrene or polyurethane, providing the insulating properties. The back of the foam is adhered to a backing board for structural support.
Fiber Cement Insulated Siding: The illustration depicts a thicker outer layer of fiber cement, known for its durability. A layer of rigid foam insulation is often installed
-behind* the fiber cement panels, attached to the sheathing. This is because the fiber cement itself does not provide significant insulation.
Foam Core Insulated Siding: This diagram shows a substantial layer of foam insulation forming the core of the panel. A thin, protective outer layer of vinyl, or another material like aluminum, is applied to both sides to provide weather resistance and a finished look. The insulation is integral to the panel itself, providing the most substantial insulation value of the three types.
Insulation Properties and R-Value
Insulated siding significantly improves a home’s energy efficiency by creating a thermal barrier against heat transfer. Understanding the R-value of your siding is crucial for determining its effectiveness in reducing energy consumption and lowering utility bills. This section will explore the relationship between R-value and energy savings, providing examples and calculations to illustrate the benefits of higher R-value siding.The R-value, or thermal resistance, measures a material’s ability to resist heat flow.
A higher R-value indicates better insulation; less heat escapes in winter and less heat enters in summer. This directly translates to reduced energy consumption for heating and cooling, resulting in substantial cost savings over time. The impact of R-value on energy savings varies depending on factors like climate, building design, and heating/cooling systems.
R-Value and Energy Efficiency
The relationship between R-value and energy efficiency is directly proportional. Each incremental increase in R-value contributes to greater energy savings.
