Product Information

Full details

The Recticel Eurowall Cavity Wall Insulation Board is designed for professional builders and contractors seeking a high-performance partial fill solution for cavity walls in new builds or refurbishment projects. By utilizing a rigid polyurethane foam core, these boards significantly boost a building's thermal efficiency and reduce heat loss; however, installers must ensure precise installation and correct placement of wall ties to maintain the integrity of the cavity.

Extended Product Information

FAQs

Can I use these boards in a full-fill cavity wall?

These are specifically designed as a partial fill insulation solution and should be installed against the inner leaf.

What is the thermal conductivity of this product?

The Recticel Eurowall has a thermal conductivity value of 0.022 W/mK.

Are these boards fire-rated?

While polyurethane foam is resistant, you must consult local building regulations and the product's technical datasheet for specific fire performance ratings in your region.

How many boards come in a pack?

This package contains 30 boards.

Do I need to leave a clear cavity?

Yes, as a partial fill product, it is intended to maintain a residual cavity as per building design requirements.

Troubleshooting

Board does not sit flush against the wall

Check the wall for mortar snots or debris; clean the surface thoroughly before re-positioning.

Gap between insulation boards

Ensure boards are tightly butted together. If a gap persists due to masonry irregularities, use a minimal expanding thermal foam to seal the void.

Pros and Cons

Pros

  • Excellent thermal conductivity rating of 0.022 W/mK
  • Foil facings provide added protection against gas diffusion
  • Rigid core offers structural stability during installation
  • Standardized dimensions allow for efficient installation between brick ties
  • Large 30-pack quantity is ideal for full-scale projects

Cons

  • Requires professional installation to ensure wall tie alignment
  • Rigid boards do not flex for irregular cavity spaces
  • Heavier than traditional glass wool alternatives

Setup, Compatibility & Care

Installation requires standard site safety equipment, including gloves and eye protection when cutting boards. Ensure the cavity is clear of mortar droppings before installation, as debris can prevent the boards from sitting flush against the inner masonry.

  1. Measure and check cavity width to ensure 100mm boards are appropriate.
  2. Apply boards to the inner leaf, ensuring joints are tightly butted.
  3. Secure using appropriate wall ties to keep the insulation firmly in place.
  4. Store boards in a dry, covered area off the ground to prevent moisture ingress to the packaging.
  5. Avoid leaving the boards exposed to prolonged direct sunlight or extreme moisture during the construction phase.
