Everything You Want to Know About Foam Board Insulation(Part 2)

Advantages and Disadvantages of Foam Board Insulation

Foam board insulation is a popular choice due to its versatility and effectiveness across a variety of applications, including ceilings, walls, and floors. Below, we explore the main advantages and some potential disadvantages of using PU/PIR foam board insulation for your building project.

Advantages of Foam Board Insulation

1.Moisture-Resistant

• The moisture resistance of PIR /PU insulation board varies among different types, but all provide a certain level of moisture control. They protect interior framing from humidity and rainfall, keeping interior sheathing warm and preventing moisture buildup. Additionally, PIR insulation board can inhibit the growth of mildew and mold within the material, although these can still appear on its surface.

2.Stops Thermal Bridging

• Foam board insulation is effective at preventing thermal bridging, which occurs when heat transfers through more conductive materials rather than the insulation. Thermal bridging often develops when there are breaks in interior insulation that intersect with materials like studs. By installing polyurethane board insulation on the exterior of the building, construction professionals can prevent thermal bridging.

3.Air Leak Prevention

• Acting as a stable seal, foam board insulation helps to stop air leaks, which can significantly impact energy efficiency by allowing too much air to enter or leave a building. Preventing air leaks also helps keep pests out, reduces allergens, and improves overall air quality. Spray foam is particularly useful for sealing smaller cracks and gaps.

Disadvantages of Foam Board Insulation

1.UV Light Sensitivity

• PIR thermal insulation board is sensitive to sunlight and UV light. Although this isn't an issue after installation, it's crucial to store the insulation properly, away from UV light, before use. Exposure to UV light can cause the insulation to become brittle and discolored.

2.Cost

• Foam board insulation is generally more expensive compared to other insulation materials. This higher upfront cost should be considered when planning your project. However, the energy savings over time can offset this initial investment, making it a cost-effective solution in the long run.

3.Installation Problems

• While no special equipment is needed for installation, it is essential to follow the installation instructions carefully. Mistakes during installation, such as improperly sealed seams between the cavities and boards, can lead to significant issues like air penetration, compromising the insulation’s effectiveness.

By weighing these advantages and disadvantages, you can make an informed decision about whether foam board insulation is the right choice for your home or building project. Despite some potential downsides, its benefits in terms of moisture resistance, thermal bridging prevention, and air leak prevention make it a reliable and efficient insulation option.
