Loft insulation boards are an essential component for any energy-efficient home, helping to reduce heat loss, lower energy bills, and increase comfort. Whether you're a professional contractor or a DIY enthusiast, understanding the different types of loft insulation boards available can help you make the best choice for your specific needs.

Types of Loft Insulation Boards

1. PIR (Polyisocyanurate) Boards

  • Examples: IKO Enertherm ALU, Recticel Eurothane GP

  • Description: PIR boards are known for their excellent thermal performance and thin profile, making them ideal for spaces where maintaining maximum headroom is crucial. They are rigid boards that can be used in various applications, including under roofing, within walls, and on floors.

     

2. Phenolic Foam Boards

  • Examples: Celotex PL4000

  • Description: Phenolic foam offers one of the highest levels of insulation per thickness. These boards are recognized for their fire performance and low smoke emission, making them a safe choice for homes.

     

3. XPS (Extruded Polystyrene) Insulation

  • Examples: Danosa Danopren TR XPS

  • Description: XPS is known for its moisture resistance and high compressive strength, making it particularly suitable for areas prone to dampness or where the insulation will be subject to heavy loads.

     

4. EPS (Expanded Polystyrene) Boards

  • Examples: Warmline EPS Insulated Plasterboard

  • Description: EPS is a lightweight and cost-effective option, offering good thermal insulation properties. It's commonly used in both new construction and retrofit applications.

     

5. Insulated Loft Deck Boards

  • Examples: Thermboard Insulated Loft Deck Board SE

  • Description: These are specialised boards designed for easy installation directly over existing joists, providing both insulation and a solid deck to walk on. They are an excellent choice for loft conversions or creating storage space in the attic.

     

Selecting the Right Board for Your Project

When choosing the right loft insulation board,consider the following:

  • Thermal Performance: Look at the R-value or U-value of the board to understand its insulation efficiency.
  • Space Constraints: Thinner, high-performance boards like PIR or phenolic might be preferred in tight spaces.
  • Application: Determine if the board is suitable for your specific application — some are better for floors, while others are designed for walls or roofs.
  • Moisture Resistance: In damp areas, consider moisture-resistant options like XPS.
  • Budget: Factor in the cost-effectiveness of the material for your project size and budget.
