Dow Blue Board

When it comes to high-quality insulation, Dow Blue Board by Dupont stands out as a go-to solution on Insulation4Us. Dow Blue Boards are renowned for their exceptional thermal resistance, durability, and moisture resistance, making them ideal for a range of insulation needs. This category mainly features two prominent products: Dupont XPS 250 Blue Board and Dupont XPS 150 Blue Board, both available in various sizes to accommodate diverse project requirements.

Dupont XPS Blue Boards are extruded polystyrene foam insulation boards, renowned for their impressive compressive strength, moisture resistance, and high R-value, ensuring optimal thermal performance. They are an excellent choice for a variety of applications due to their versatility, durability, and efficiency in maintaining temperature stability.

Practical Uses

Dupont XPS Blue Boards are multifunctional and can be utilized in numerous insulation applications including:

• Wall Insulation: Ideal for both interior and exterior walls, providing an excellent thermal barrier.
• Roof Insulation: Acts as a superior insulating layer on roofs, minimizing heat loss.
• Foundation Insulation: Offers crucial protection against heat loss around the foundations.
• Below-Grade Insulation: Exceptional for insulating beneath the ground level, preventing the intrusion of moisture and maintaining temperature stability.

Product Types

In this category, the products can be generally grouped into two types based on their compressive strength and density:

Dupont XPS 250 Blue Board:

• Higher density and compressive strength make it suitable for applications requiring robust support and durability.
• Suitable for heavy-load applications like beneath concrete slabs and foundations.
• Offers a higher level of thermal resistance compared to XPS 150, making it more appropriate for extreme temperature conditions.

Dupont XPS 150 Blue Board:

• Offers a slightly lower density and compressive strength, making it ideal for standard insulation applications.
• Ideal for wall and roof insulation where extreme load-bearing capacity is not a prerequisite.
• Provides adequate thermal resistance and is a cost-effective solution for most insulation needs.

Guidance on Selection

When selecting the appropriate Dow Blue Board, consider the following aspects:

• Application: Determine the specific use, whether it’s for wall, roof, foundation, or below-grade insulation.
• Load-Bearing Capacity: For applications with heavy loads, opt for XPS 250 due to its higher compressive strength.
• Thermal Resistance: For regions with extreme temperature variations, XPS 250 offers superior thermal stability.
• Budget Constraints: For standard insulation needs where high compressive strength is not crucial, XPS 150 is a more economical choice.
