When considering floor insulation, it's essential to select the most suitable product for your specific needs, environmental conditions, and application methods. At Insulation4us, our wide array of high-quality floor insulation products ensures you find the optimal solution for your projects, catering to varying sizes, types, and insulation requirements.

Polyiso Insulation

  • Examples: Dow Thermax Sheathing, Hunter Panels Xci Foil Polyiso Panel.
  • Uses: Suited for continuous insulation to assist in energy conservation and can be applied over most surfaces. Polyiso is known for its high R-value per inch, making it an effective insulator.

Fiberglass Insulation

  • Examples: Owens Corning R-38 Unfaced Fiberglass Insulation Batts, Knauf Ecoroll Kraft Faced Fiberglass Insulation Roll.
  • Uses: Widely used for thermal and acoustic insulation. It is versatile, cost-effective, and easy to install, making it suitable for floors, walls, and ceilings.

XPS Insulation Boards

  • Examples: Dupont XPS 250 Blue Board, Owens Corning FOAMULAR 150 XPS Insulation Board.
  • Uses: Excellent for insulating basements, slabs, and other areas requiring moisture resistance and high R-values.

Reflective Foil Insulation

  • Examples: Double Bubble Reflective Foil Insulation Rolls, Single Bubble White Foil Reflective Insulation Rolls.
  • Uses: Ideal for reducing radiant heat and enhancing thermal performance in floors, walls, and roofs.

Sound Attenuation Fire Blankets

  • Example: Thermafiber Sound Attenuation Fire Blankets (SAFB).
  • Uses: Primarily used for sound absorption and fire resistance in various residential and commercial applications.

Selection Guidance

1. Consider Application Area

  • Above Grade: Fiberglass Batts or Polyiso can be suitable.
  • Below Grade: Opt for moisture-resistant products like XPS insulation boards.

2. Assess Required R-value

  • Higher R-value products offer better thermal resistance. Determine the needed R-value based on local building codes and climate.

3. Evaluate Installation Ease

  • Choose products that align with your installation capabilities—some products, like fiberglass batts, are more user-friendly and suitable for DIY projects.

4. Budget Constraints

  • Establish a budget and select a product that offers the best value for the cost. While higher R-value products might be more expensive, they can offer better long-term value.
