Cavity Wall Insulation in Dublin

At Luca Line Services, we specialise in the installation of cavity wall insulation which prevents heat escaping through the walls of your home.

Cavity walls are built using two layers of bricks and/or blocks leaving a gap in-between. Insulating this gap will ensure your home is a warmer and more comfortable place to spend time in.

Cavity wall insulation involves the installation of insulation in the internal cavity of your external walls. This is cheaper to install than other wall insulation options.

Insulating your home in this fashion is both effective and efficient, and reduces heat loss through your walls by up to 30%.

Benefits of Cavity Wall Insulation

If you are looking to increase the efficiency of your home or building by acquiring insulation then you may be eligible for a grant from the Sustainable Energy Authority of Ireland (SEAI).

The Home Energy Saving Scheme was launched to encourage homeowners to improve the energy efficiency of their home and contribute to a greener environment. A grant of up to €1,800 is available and can make a considerable contribution to the cost of work carried out.

Is cavity wall insulation right for your home?

Many Irish homes built from the 1970s onwards have two leaves of block with a gap, or cavity, between them. If that cavity is empty or only partly filled, heat escapes straight through your walls. Filling it is one of the quickest and most cost-effective upgrades you can make.

Not every wall is suitable. Solid concrete and hollow block walls have no cavity to fill, and some cavities are too narrow or already contain insulation. During our free survey we check your walls with a borescope camera and tell you honestly whether cavity fill will work, or whether dry lining or external wall insulation is the better option.

SEAI cavity wall insulation grant

To qualify, your home must have been built and occupied before 2011, and the work must be done by an SEAI-registered contractor. If you have had a cavity wall grant before, you may now be able to claim a second wall grant for internal or external insulation. See our SEAI grants guide for details.

How cavity wall insulation is installed

1. Survey: we inspect the cavity and check for damp, damaged wall ties or blocked vents.
2. Drilling: small holes are drilled in the outer wall in a set pattern.
3. Filling: insulation is blown into the cavity until it is completely filled.
4. Making good: the holes are filled and matched as closely as possible to your existing finish.
5. Ventilation check: we make sure your home still has the ventilation it needs to prevent condensation.

Most homes are completed in a single day, with no need to move furniture or redecorate inside. For the biggest saving, pair cavity wall insulation with attic insulation. Book your free survey to find out what your home needs.
