Looking for ways to make your home more energy-efficient? Cavity wall insulation could be what you need. This is where insulation material is put between the inner and outer walls of your house. It's really good for Irish weather. This insulation uses things like bonded beads and spray foam to stop air from moving around, which keeps the heat in. 

If you're living in Ireland, adding cavity wall insulation can make your home more energy-efficient and lower your heating bills, and you might even get grants from the Sustainable Energy Authority of Ireland (SEAI).

In this blog post, we'll explain all about cavity wall insulation, how it works, the different materials used, and why it's great for Irish homes.

Let's find out how this insulation method can transform your living space into a more energy-efficient and comfortable home.

Key Takeaways

  • Cavity wall insulation is the process of injecting insulation material into the space between the inner and outer walls of a building to improve energy efficiency.
  • Two common types of insulation materials used are bonded bead and spray foam, which help impede air movement and reduce heat loss.
  • Upgrading cavity wall insulation can result in improved energy efficiency, reduced heating costs, and eligibility for grants from the SEAI (Sustainable Energy Authority of Ireland).
  • Cavity wall insulation works by filling the gap between walls, preventing air movement, and creating a barrier that keeps homes warmer.

When it comes to keeping your home warm and energy-efficient, one effective solution stands out: cavity wall insulation. But what exactly is it? Let's break it down.

What is Cavity Wall Insulation?

Cavity wall insulation is the process of injecting insulation material into the space between the inner and outer walls of a building, effectively reducing air movement and improving energy efficiency.

Process of injecting insulation material into cavity

First, we check the wall. Then, we drill small holes in it from outside. The next step is to put the insulation into the cavity. We use a pump for this. It squirts silver graphite-bonded beads under high pressure into the space between walls.

These beads stop air from moving around inside the cavity. This method helps your home keep heat better and lowers your heating bills.

Types of insulation (bonded bead, spray foam)

There are different types of insulation materials that can be used for cavity wall insulation. Two common options are bonded beads and spray foam.

Bonded bead insulation involves injecting small spherical beads into the cavity. These beads are made from silver graphite, which helps to impede air movement within the cavity. This type of insulation is effective in filling any air gaps or uninsulated areas, improving the overall energy efficiency of your home.

Spray foam insulation, on the other hand, involves using a special liquid foam that expands when sprayed into the cavity. It fills up all the nooks and crannies, creating a complete seal and preventing heat loss through air leakage.

Benefits of Cavity Wall Insulation

Cavity wall insulation provides several benefits, including improved energy efficiency, the availability of an SEAI grant, and reduced heating costs.

Improved energy efficiency

Upgrading your cavity wall insulation can greatly improve the energy efficiency of your home. By filling the cavity with insulation material, it helps to stop heat from escaping through the walls.

So, this means that you won't need to use as much energy to keep your home warm, ultimately reducing your heating bills. It's a cost-effective way to make your home more energy-efficient and comfortable year-round.

Plus, if you qualify for the SEAI grant, you could receive up to €1700 towards the cost of upgrading your cavity wall insulation.

SEAI grant available

The Sustainable Energy Authority of Ireland (SEAI) offers a grant of up to €1700 for cavity wall insulation upgrades. This means that if you are considering getting your cavity walls insulated, you may be eligible for financial assistance.

The grant can help offset the cost of the insulation and make it more affordable for homeowners. It's important to note that this grant is available specifically for cavity wall insulation and not other types of insulation projects.

So, if you're looking to improve your home's energy efficiency and save on heating costs, taking advantage of the SEAI grant could be a smart choice.

Reduced heating costs

Upgrading your cavity wall insulation can help you save money on heating costs. With proper insulation, heat loss from your home is minimised, meaning you won't need to use as much energy to keep your house warm.

This can result in significant savings on your heating bills throughout the year. In addition, by improving the energy efficiency of your home, you'll also be reducing your carbon footprint and contributing to a more sustainable future.

So, not only will you be cosy in the winter months, but you'll also be saving money and helping the environment at the same time!

How Cavity Wall Insulation Works?

Cavity wall insulation works by impeding air movement and completely filling the space between the inner and outer walls of a building.

Impedes Air Movement

Cavity wall insulation is designed to impede air movement within the cavity. The insulation material, such as silver graphite-bonded beads or foam fill, is injected under pressure into the space between the inner and outer walls.

So, this helps fill any air gaps and un-insulated areas, preventing heat from escaping and cold air from entering your home. By impeding air movement, cavity wall insulation improves energy efficiency and can significantly reduce your heating costs.

It's an effective solution for both new builds and retrofits, ensuring that your home stays warm and cosy all year.

Completely fills cavity

Cavity wall insulation completely fills the gap between the inner and outer walls of your home. By injecting insulating material into the cavity, it creates a barrier that stops air movement and helps to keep your home warmer for longer.

So, this means that heat is less likely to escape, reducing the need for heating and lowering your energy bills. It's an effective way to improve energy efficiency in your home and make it more comfortable year-round.

Furthermore, with some companies offering a 24-year guarantee, you can have peace of mind knowing that your cavity wall insulation will last for years to come.

Costs and grants

Cavity wall insulation is a cost-effective way to improve the energy efficiency of your home. The good news is that there is a grant available from the SEAI (Sustainable Energy Authority of Ireland) for cavity wall insulation upgrades, which can help reduce the overall cost.

Furthermore, with this grant, you can receive up to €1700 towards the cost of the insulation work. So not only will you save money on your heating bills in the long run, but you can also get financial assistance to make the upgrade more affordable.

It's definitely worth considering if you want to make your home more comfortable and energy-efficient.

Types of insulation

There are different types of insulation that can be used for cavity wall insulation. One option is bonded bead insulation, which involves injecting silver graphite beads into the cavity to impede air movement.
