Types of Insulated Sheathing Boards

Polyisocyanurate (PIR) Sheathing Boards

Polyisocyanurate, or PIR, is a top choice for insulation. It works well if you need strong heat resistance. PIR boards have a high R-value, which shows how well they block heat. The National Roofing Contractor’s Association (NRCA) says PIR has an R-value of about R-5.6 per inch in warm areas and R-5.0 per inch in cold places. This makes it great for saving energy in buildings.

PIR boards are also good at resisting fire. They handle fire better than many other materials, making them safer. However, they cost more than other options. If your project focuses on saving energy and safety, the higher price may be worth it.

Tip: Use PIR boards in places needing strong insulation and fire safety, like roofs or walls in extreme weather areas.

Extruded Polystyrene (XPS) Sheathing Boards

Extruded Polystyrene, or XPS, is tough and resists water well. It keeps its insulation ability even when wet. XPS boards have an R-value of about 5.0 per inch, making them a solid choice for energy-saving projects.

XPS stands out because it doesn’t soak up much water. This helps it stay effective over time. It’s a great pick for areas like foundation walls or basements where moisture is common.

XPS costs more than EPS but lasts longer and handles dampness better. It’s worth the extra cost in wet areas.

Expanded Polystyrene (EPS) Sheathing Boards

If you want a cheaper option, Expanded Polystyrene (EPS) is a good pick. EPS is light, easy to use, and gives moderate insulation with an R-value between 3.6 and 4.2 per inch. It doesn’t insulate as well as PIR or XPS, but it’s popular because it’s affordable.

EPS lets some moisture pass through, which can help in certain cases. But you need to manage moisture carefully to avoid problems like condensation. EPS is often used in walls and floors where saving money and basic insulation are important.

Note: EPS made up over 76% of the market in 2020, showing its popularity in budget-friendly projects.

Each type of insulated sheathing board has its own strengths. Pick one based on your needs for heat resistance, water protection, and cost.

Magnesium Sheathing Boards

Magnesium sheathing boards, also called MgO boards, are strong and useful for modern buildings. Made from magnesium oxide, a natural material, they work well in places needing fire safety, water protection, and strength.

A key feature of MgO boards is that they don’t burn. They can handle high heat without catching fire, making them safer than plywood or OSB (oriented strand board). They also resist water very well. Unlike OSB, which can swell or grow mold when wet, MgO boards stay strong even in damp conditions.

Here’s how MgO boards compare to OSB and plywood:

MgO boards are great for walls, ceilings, and floors in homes or offices. They also work well outside where weather can be harsh. While they cost more upfront, they last longer and need less fixing, saving money over time.

Tip: Use MgO boards in places with fire risks or high moisture, like kitchens, bathrooms, or outside walls.

Fiberglass-Faced Sheathing Boards

Fiberglass-faced sheathing boards are another good choice for modern buildings. These boards have a gypsum center and fiberglass layers, giving them fire safety, water resistance, and strength.

One big benefit of fiberglass-faced boards is their fire safety. They meet strict fire rules, like the A1 Reaction to Fire standard (BS EN 13501-1) and non-combustibility tests like ASTM E136. This makes them a safe pick for projects needing fire protection.

These boards also fight mold and mildew well. Tests like ASTM D3273 gave them a perfect score of 10 for mold resistance. This makes them ideal for wet places like bathrooms or basements.

Here’s a quick look at their fire and water performance:

Fiberglass-faced boards are light and simple to install. They are great for new buildings or fixing old ones. Common uses include walls, ceilings, and roofs, especially in places needing fire and water safety.

Note: Fiberglass-faced boards are a better option than regular gypsum boards when you need extra strength and protection from fire and mold.

Benefits of Insulated Sheathing Boards

Energy Efficiency

Insulated sheathing boards help buildings use less energy. They stop heat from escaping in winter and keep spaces cool in summer. This means heating and cooling systems don’t need to work as hard, saving money on energy bills. Materials like Polyisocyanurate (PIR) and Extruded Polystyrene (XPS) have high R-values, which measure how well they insulate per inch of thickness.

Using these boards improves energy efficiency in homes and buildings. It saves money and lowers your carbon footprint, helping the environment.

Tip: Combine insulated sheathing boards with energy-saving windows and doors for better insulation.

Structural Support

Insulated sheathing boards do more than insulate; they also make buildings stronger. Structural Insulated Panels (SIPs) combine foam cores with sheathing layers to act like steel columns. The foam works as the center, while the sheathing adds strength on the sides.

These boards are great for projects needing insulation and extra strength. They improve durability and stability in construction.

Moisture and Fire Resistance

Insulated sheathing boards protect buildings from water and fire damage. Boards like Magnesium Oxide (MgO) and fiberglass-faced sheathing resist mold and mildew, making them ideal for damp places like basements or bathrooms.

For fire safety, materials like fire-retardant EPS and fiberglass-faced boards meet strict standards. Fire-retardant EPS melts only in small areas, while regular EPS melts more.

Choosing the right board prevents water problems and improves fire safety.

Note: Always check fire ratings to meet building rules.

Sustainability Contributions

Choosing an insulated sheathing board helps create a greener future. These boards cut down the environmental effects of building. They save energy, which reduces greenhouse gases and fights climate change.

Many boards use materials that can be recycled or reused. For instance, Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS) can often be used again. This lowers waste and saves resources. Some boards, like Magnesium Oxide (MgO), are made from natural materials, making them eco-friendly.

These boards also save energy over a building’s life. Better insulation means heating and cooling systems work less. This saves energy and cuts utility bills. Over time, the energy saved balances out the cost of making the boards.

Some boards meet green building certifications like LEED. These certifications show the materials follow strict eco-friendly rules. Using certified boards can make your project more sustainable and valuable.

Tip: Pick brands that focus on eco-friendly practices, like using recycled materials or cutting carbon emissions.

By choosing the right insulated sheathing board, you help the planet and build stronger, energy-saving structures.

Applications of Insulated Sheathing Boards

Residential Construction

Insulated sheathing boards help homes stay warm or cool. They stop heat from moving through walls, making rooms comfortable. This also lowers heating and cooling costs. Cold places, like zones 6, 7, and 8, need more insulation. Walls there should have R-30 or R-20 plus an extra R-5 layer. Warm areas, such as zones 1 and 2, need less insulation, sometimes as low as R-13.

Picking the right board helps meet these needs. It saves money and helps the planet by using less energy.

Commercial and Industrial Buildings

These boards are useful in big buildings like offices or factories. They save energy and make walls and roofs stronger. This is important for large structures. Boards like fiberglass-faced ones are good for fire safety. They also resist mold, which is helpful in damp places like storage rooms.
