• Polyisocyanurate (Polyiso): Foil-wrapped, it provides the highest R-value at R-6.5 per inch.

Beyond its insulation capabilities, insulated sheathing serves multiple essential functions. It acts as traditional sheathing, providing a robust surface for siding while also delivering vital structural support to the building frame. By utilizing insulated sheathing, you gain a dual-purpose material that enhances both the durability and energy performance of your property.

Types of Insulated Sheathing

Insulated sheathing includes various types, with foam board insulation and reflective insulation being prominent options. Each type offers unique benefits and applications in construction.

Foam Board Insulation

Foam board insulation combines foam insulation with structural materials like Oriented Strand Board (OSB) or plywood. It consists of various foam types:

• EPS (Expanded Polystyrene): Offers lower density with an R-value of approximately R-4.0 per inch, making it suitable for a range of applications.
• XPS (Extruded Polystyrene): Provides higher moisture resistance and an R-value of about R-5.0 per inch, ideal for below-grade applications.
• Polyiso (Polyisocyanurate): Delivers the highest R-value, ranging from R-6.0 to R-7.0 per inch, and often features a foil facer that enhances thermal performance.

Foam board insulation not only provides structural strength but also minimizes thermal bridging while increasing the overall R-value of the wall assembly. It acts as a water-resistant and air barrier when properly sealed, contributing to energy efficiency while reducing labor costs and material waste.

Reflective Insulation

Reflective insulation employs reflective materials, often installed in attics and walls, to manage radiant heat. Its unique design consists of highly reflective surfaces, such as aluminum foil, which reflect radiant heat rather than absorb it. This can significantly reduce heat gain in warm climates and heat loss in colder situations.

Reflective insulation comes in various forms:

• Radiant Barrier: Installed in attics to reflect heat away from living spaces, lowering cooling costs.
• Reflective Foil Insulation: Used in walls or ceilings, reflecting radiant heat back toward its source, enhancing comfort.

By effectively reducing reliance on heating and cooling systems, reflective insulation can enhance energy efficiency and indoor comfort. Its simplicity in installation makes it a viable option during renovations or new construction.

Benefits of Insulated Sheathing

This design reduces thermal bridging by enveloping the entire exterior wall, including window, door, and stud areas. A consistent thermal barrier improves whole-wall R-values, creating a more efficient energy envelope for your home.

Moisture Control

Insulated sheathing also plays a vital role in moisture control.

• Moisture Resistance: The moisture-resistant properties of insulated sheathing help protect your walls from water infiltration. When properly installed, this sheathing acts as a barrier, minimizing the risk of mold and water damage.
• Air Tightness: This sheathing improves air tightness, reducing drafts and limiting air leakage. Enhanced air control lessens moisture accumulation, contributing to a healthier indoor environment and further preventing structural damage.

By integrating insulated sheathing, you enhance your home's energy efficiency and moisture management, leading to a more comfortable and durable living space.

Installation Process of Insulated Sheathing

Installing insulated sheathing requires careful preparation and application techniques to ensure effective insulation and moisture control.

Preparation

Selecting the correct type of insulated sheathing is crucial for installation. You should choose from various rigid foam insulation types, including foam plastic insulating sheathing (FPIS). Consider factors like climate, compliance with building codes, and the cladding type planned for your project.

To determine the quantity required, measure the length and height of each wall to calculate the total exterior square footage. Divide this total by the square feet of a single sheet of sheathing. For instance, for a wall that's 15 feet long and 10 feet high, using 4-foot by 8-foot sheathing boards, you'll need approximately 5 boards. Ensure you also have the right tools ready, including a circular saw, measuring tape, and fastening supplies.

Application Techniques

Install the insulated sheathing by starting at a designated corner of the wall. Use a level to ensure the first board is straight.
