What factors do pumped cavity wall insulation costs depend on?
1. When was your home built?
Pre-1978, 1978-1982, 1983-1993, 1994-2004, 2005 - onwards. This will help us identify the type of cavity you have and therefore the method we will need to use to fill the cavity and the size of the cavity itself.
2. Where do you live?
The length of time we spend going to and returning from home will add to the cost. Fuel consumption and time travelling can add to the costs. We aim to get you a contractor that is closest to your property, saving you money and saving them time.
3. What type of cavity wall insulation material you use.
Blown mineral fibre, polystyrene beads or granules or slow pour foam.
4. If you don't know the period when your home was built
we will have to determine the size of the cavity. This can be done by drilling into the wallor by looking behind an electrical box.
5. Let us know your Eircode.
We can tell alot about a house by looking at it on google maps.
What are the benifits of cavity wall insulation?
1. Increased energy efficiency: Cavity wall insulation can help to prevent heat loss through the walls of a building, making it easier to maintain a comfortable temperature inside and reducing the amount of energy needed to heat the home.
2. Lower energy bills: By reducing the amount of energy needed to heat a home, cavity wall insulation can help to lower energy bills.
3. Improved thermal comfort: Insulating the cavity walls of a building can help to reduce drafts and cold spots, making the home more comfortable to live in.
4. Reduced carbon footprint: By reducing energy consumption, cavity wall insulation can help to reduce a building's carbon footprint.
5. Can increase the value of your property.
6. Noise reduction : It also helps to reduce external noise from entering the house
7.Increased durability: Insulating the walls of a building can help to protect them from moisture and freeze-thaw damage, increasing the overall durability of the structure.
8. There are a few ways to determine if your walls have a cavity suitable for insulation:
How so I find out if my walls have a cavity?
1. Visual Inspection: In some cases, it may be possible to visually inspect the walls to determine if there is a cavity. For example, if the exterior of the building is made of brick, there may be a horizontal gap between the bricks that indicates a cavity.
2. Measuring the thickness of the walls: The thickness of the walls can be measured using a thickness gauge or a set of calipers. The thickness of the cavity wall will be greater than that of a solid wall
3. Consult with an energy assessor or professional contractor: A professional energy assessor or contractor will be able to inspect your home and determine whether or not the walls have a suitable cavity for insulation. They can also advice on the most suitable insulation materials and method for your home.
4. Magnetic or thermal imaging: Both magnetic and thermal imaging can be used to detect the presence of a cavity behind a wall. A magnetic wand would be passed over the wall, this will detect metal fixings that are typical of cavity walls. Thermal imaging is used to detect temperature difference between a cavity and solid walls.
It is always recommended to consult with a professional before starting any insulation work to ensure that the process is done safely and correctly.

Cavity Wall Insulation FAQ's
What is cavity wall insulation?
Cavity wall insulation is the material put between the internal and external walls of your home. It comes in 3 types. Expanding slow pour foam insulation, Mineral fibre insulation and Bounded poly-bead insulation.
Is it worth getting cavity wall insulation?
The answer to that question is 100% yes, if your home has a cavity that is not insulated you should get it filled with bounded beads or slow pour foam as soon as possible.
Heat loss through the walls of your home can be as much as 35% so a filled cavity prevents heat loss, saves you money and helps reduce co2. So yes getting cavity wall insulation done is worth it.
What is the best insulation for cavity walls?
There are 3 main types of insulation for cavity walls.
1. Expanding slow pour foam insulation
2. Mineral fibre insulation
3. Bounded poly-bead insulation
To judge the best type of insulation for your property is difficult without knowing what type of cavity you have so we recommend asking your contractor but the most popular type of cavity wall insulation used in Ireland is bonded bead insulation.
Are there cavity wall insulation grants?
Yes the Irish government via the SEAI offer grants for insulation upgrades
| SEAI Insulation Grants | |||
|---|---|---|---|
| Energy Upgrades | Grant Value | ||
| Cavity Wall Insulation Grant | Grant Value | ||
| Apartment (any) | €700 | ||
| Mid-Terrace | €800 | ||
| Semi-detached or end of terrace | €1,200 | ||
| Detached house | €1,700 | ||
What are the advantages and disadvantages of cavity wall insulation?
Advantages of cavity walls:
Moisture will not be able to travel from the outside to inside wall making the cavity a dampness barrier.
The cavity filled layer of insulation does not provide a conductor of heat dramatically reducing heat loss saving you money.
Filling the cavity is the cheapest way to prevent heat loss via your walls. External and dry lining are much more expensive.
There is no change to the size of your walls and there is minimal disruption during installation.
There will be a lowering of condensation levels reducing the threat of damp and mould buildup.
Disadvantages of cavity walls:
When cavity walls were first used they were to form a barrier to moisture. In certain cases near the coast for example there is a possibility that the filled cavity might get damp due to driving rain and storms.
If not properly installed there can be cold spots that will enable heat loss making the walls inefficient when it comes to preventing heat loss. It is therefore important for the contractor to follow the manufacturer guideline when pumping the cavities.
Does cavity wall insulation cause damp?
Generally speaking cavity wall insulation does not cause damp, far from it, if properly installed following the manufacture hole pattern instructions, making sure the whole cavity is filled, the risk of damp is greatly reduced.
If however there are any issues with the installation, where the beads or foam have not filled everywhere this can create cold spots where damp can occur.
