Cavity Wall Insulation

“Pump “Cavity

Cavity wall insulation is a vital energy-efficient solution for homes. It involves filling the gap between inner and outer walls with insulating material to reduce heat loss and improve thermal performance.

We use a graphite bonded bead Cavity Wall Insulation for new builds, SEAI projects, residential and commercial work.

Cavity Wall Insulation is an expanded polystyrene material which is injected in bead form with a binding agent into masonry cavity walls. The bonding agent is used to provide long-term stability to the insulant. The graphite bonded bead Cavity Wall Insulation System can be installed using a compressed air delivery system.

Before commencing work the installing operative team that the property has been correctly surveyed and is suitable for the system.

Installation Procedure

1. Once our installers have arrived at site, they will survey the house in detail & outline where our drill patterns are going on the outer leaf of the external walls.

2. This system is installed using a compressed air system approved and notified to NSAI Agrément.

3. Metro provides all necessary hoses, drilling tools equipment and materials for making good the walls after the installation of the Cavity Wall Insulation System.

4. The product is injected into the cavity (having determined the correct bead/bonding agent ratio by test) through a flexible pipe fitted with a Unidirectional or Directional Nozzle.

5. The material packs to a uniform density in the cavity. Holes beneath ground-floor windows are injected first and filling then continues upwards until a complete fill has been achieved.

6. After injection, the wall is made good to match the existing finish as closely as possible using mortar or similar waterproofing mix.

Why choose this sytem?

A cost-effective system where the payback period is shorter than other methods, in SEAI Work the grants available can cover up to 50% of the costs in most cases.

Most jobs are completed in maximum two days.

High level thermal performance available & suitable for both commercial & residential construction.

Zero waste left on site post installation.

External Wall Insulation

“External “Metro

External wall insulation is a highly effective method for improving a building's energy efficiency and thermal comfort. It involves adding insulation material to the exterior walls and then covering it with a protective finish. This not only enhances the building's appearance but also reduces heat loss and energy consumption.

Benefits of External Wall Insulation:
  • Energy Efficiency: Significant reduction in heat loss, leading to lower heating bills.
  • Improved Comfort: Consistent indoor temperatures and reduced cold spots.
  • Enhanced Aesthetics: Exterior cladding options improve the appearance of the building.
  • Damp Prevention: Acts as a barrier against moisture, preventing damp issues.
  • Environmental Impact: Reduced carbon emissions and a more sustainable building.

Attic Insulation

“Metro “Attic

Attic insulation is the most practical and efficient method for insulating your ceiling and improving energy efficiency in your home.

  • For SEAI projects and new builds, a minimum insulation depth of 300mm is required. We offer top-ups ranging from 100mm to 400mm to meet your specific needs.
  • Lagging pipes, supplying and fitting ventilation methods via the soffit and supplying and fitting work boards to access different services located in the attic are all additional services that we offer.
  • Significant heat loss reduction is achieved upon installation, with most projects completed within a day.
  • Attic insulation greatly enhances the thermal performance of your home, achieving a conductivity rate of .16 W/m²K.
  • SEAI grants of up to €1500.00 are available to help offset the cost.
  • Our experienced consultants will survey your property, recommend necessary measures to meet current building regulations, and advise you on available grants or rebates.

Investing in attic insulation not only improves your home's energy efficiency but also provides long-term savings on your heating bills.
