Product Information


The Eco-Cavity is a high-performance, partial fill cavity wall insulation board, engineered to offer an optimal balance between thermal insulation and moisture resistance. Measuring 0.45m x 1.2m, each board is crafted to seamlessly integrate into standard masonry constructions, ensuring a snug fit and easy installation, compared to some other commonly used insulants.

Key Features:

  • Thermal Conductivity: Boasting a thermal conductivity of just 0.022 W/mK, Eco-Cavity ensures your building retains heat more effectively, reducing energy bills and enhancing occupant comfort throughout the year.

  • Partial Fill Solution: Specially designed for use within partial fill cavity walls, Eco-Cavity maintains a vital air gap between the insulation layer and the masonry outer leaf, providing a robust barrier against external moisture and enhancing the building's longevity.

  • Lightweight and Easy to Handle compared to some other commonly used insulants: Despite its robust performance, Eco-Cavity is remarkably lightweight, simplifying logistics and handling on-site, and allowing for quick, efficient installation.

  • High-Performance Core: At the heart of each board lies a rigid polyisocyanurate (PIR) insulation core, known for its excellent thermal insulation properties and durability.

  • Dual Aluminium Composite Foil Facing: Eco-Cavity features an aluminium composite foil facing on both sides, bonded during the manufacturing process for added durability and moisture resistance.

  • Compatibility: Eco-Cavity boards are designed to work in harmony with brick and block dimensions, facilitating the insertion of wall ties at appropriate intervals and ensuring a secure, effective installation.

  • Euroclass Rating: Under System 4 AVCP, Eco-Cavity has a Euroclass rating of F.

  • Compressive Strength: With a compressive strength of 140 kPa when tested at 10% compression according to BS EN 826: 2013.

 

Whether you're a professional builder, architect, or a homeowner looking to upgrade your property's thermal efficiency, the Eco-Cavity Insulation Board is your go-to choice for a cost-effective, high-performance insulation solution.

Pros & Cons

 Pros
  • High performance with a conductivity of 0.022 W/mK, leading to enhanced energy savings and improved indoor comfort.
  • Designed for partial fill cavity walls, allowing for a residual air gap that acts as a barrier against moisture penetration, thus protecting the structural integrity of the building.
  • Lightweight and easy to handle compared to some other commonly used insulants, facilitating transport and installation, which can speed up construction timelines and reduce labor costs.
  • High-performance rigid polyisocyanurate (PIR) insulation core offers durability and long-term thermal performance.
  • Aluminium composite foil facing on both sides enhances moisture resistance and durability, further protecting the insulation core.
Cons
  • The requirement for a residual air gap, while beneficial for moisture prevention, may not be optimal for projects requiring full-fill insulation solutions to meet specific energy efficiency or building regulation targets.
  • While the compressive strength of 140 kPa is suitable for many applications, extremely high-load areas might require a product with greater compressive strength to avoid compression or deformation over time.

Frequently Asked Questions

What is Eco-Cavity insulation used for?

Eco-Cavity is specifically designed for use in partial fill cavity wall insulation applications. It is ideal for enhancing thermal efficiency in masonry walls while maintaining a clear air gap to prevent moisture penetration.

Can Eco-Cavity insulation be used in full-fill applications?

No, Eco-Cavity insulation is intended for partial fill applications. Its design includes maintaining a residual air gap between the insulation and the masonry outer leaf, which is crucial for its moisture barrier properties.

How does Eco-Cavity improve energy efficiency?

Eco-Cavity has a low thermal conductivity of 0.022 W/mK, meaning it effectively reduces heat transfer through the walls. This improves the building's energy efficiency, leading to lower energy bills and enhanced indoor comfort.

Is Eco-Cavity easy to install?

Yes, Eco-Cavity is lightweight and easy to handle compared to some other commonly used insulants, making it convenient for transport and installation. Its dimensions are coordinated with brick and block sizes, facilitating easy insertion of wall ties at appropriate intervals.

What are the fire safety ratings of Eco-Cavity?

It has a Euroclass rating of F

How does the aluminium composite foil facing benefit Eco-Cavity?

The aluminium composite foil facing on both sides of Eco-Cavity enhances its moisture resistance and durability. This protective layer is bonded to the insulation core, ensuring long-term performance and protection against environmental elements.

Can Eco-Cavity be used in areas with high moisture?

Yes, the design of Eco-Cavity includes an air gap that acts as a barrier to external moisture penetration, making it suitable for use in areas where moisture management is a concern.

What is the compressive strength of Eco-Cavity?

Eco-Cavity has a compressive strength of 140 kPa when tested at 10% compression according to BS EN 826: 2013. This makes it suitable for a wide range of applications, though high-load areas may require additional considerations.
