Polyurethane Foam Insulation | Polyurethane Foam Sheets

Insulation4Us offers a variety of polyurethane foam sheets, specifically Polyiso rigid foam insulation boards, ideal for different insulation needs. These products are typically used for insulating walls, roofs, and floors and are well-known for their high R-value, water resistance, and excellent thermal performance, making them an essential component in construction projects.

The Polyurethane Foam Sheets category at Insulation4Us includes products primarily from renowned vendors like R-Max and Hunter Panels. These brands are recognized for producing high-quality insulation solutions that are dependable and durable. The products in this category come in different sizes, primarily in 4ft x 8ft dimensions, but they are also available in various thicknesses to suit diverse project requirements. 

What is R9.5 Polyurethane Foam Insulation?

R9.5 Polyurethane Foam Insulation refers to rigid foam boards made from polyisocyanurate (polyiso), designed to deliver a thermal resistance (R-value) of 9.5. These closed-cell insulation panels are commonly foil-faced on both sides, enhancing thermal performance while also acting as a radiant barrier. With a high R-value per inch, they provide effective insulation using minimal thickness, making them ideal for space-restricted applications like wall cavities, ceilings, and retrofit projects.

Types of Polyurethane Foam Sheets

Standard Polyiso Rigid Foam Insulation Boards: Products like RMax Thermasheath and Hunter Panels Xci are versatile and can be used for general insulation purposes in walls, roofs, and floors.

Foil-Faced Polyiso Panels: Products such as Hunter Panels Xci Foil offer a reflective surface, optimizing energy efficiency by reflecting radiant heat.

Specialty Polyiso Panels: Certain products are designed with added features, like Hunter Panels XCI with ply attached, to offer structural support and additional functionality.

Applications of Polyurethane Foam Sheets

• Building Insulation: The primary use of these products is to provide thermal insulation in buildings, optimizing energy efficiency and reducing energy costs.
• Roofing Insulation: Several products, such as H-Shield HD Roofing Insulation Panels, are designed specifically for roofing applications, offering added protection against the elements.
• Air Barriers: Products like Rmax ECOMAXci Air Barrier are specifically designed to act as air- and water-resistant barriers, enhancing the building's structural integrity and indoor comfort.

Benefits of R9.5 Polyurethane Foam Boards

• High Thermal Performance: Achieves R9.5 in a thin profile, reducing heat loss without sacrificing internal space.
• Moisture Resistance: Closed-cell structure prevents water absorption—ideal for damp or humid environments like basements or external walls.
• Easy to Install: Lightweight and easy to cut, these boards fit seamlessly into standard construction dimensions.
• Air & Vapor Barrier: Foil facings provide additional protection by controlling air leaks and acting as a vapour retarder.
• Energy Efficiency: Helps reduce heating and cooling costs year-round by minimising thermal bridging.

Choosing the Right Product

Selecting the appropriate polyurethane foam sheet depends on several factors such as the area of application, desired R-value, and specific project requirements.

Evaluate the Need: Determine the insulation requirements based on the area of application—whether it's for the wall, roof, or floor.

Consider the R-value: Higher R-value products offer better thermal resistance and are more effective insulators.

Assess Additional Features: Products with added functionalities like air barrier properties or attached ply may offer added benefits depending on the project's needs.
