What is External Wall Insulation?

If your house was built pre 1930s the external walls are likely solid, meaning heat will easily escape. You could be losing up to 30% of your heat through the walls! Your solid walls are unsuitable for cavity wall insulation, so external insulation is what you need.

External or ‘solid’ wall insulation is the most cost effective and comprehensive way of insulating your home against the Irish winter. Just like wrapping your house in a blanket, this type of insulation is fixed to the exterior of your house. We then render it with an attractive, protective coating which will help to extend the lifetime of your home’s exterior. As it is fixed to the outside of your house, it does not affect the size of your living space.

What Are the Benefits of External Insulation?

Once your exterior wall insulation is in place, it allows your walls to retain heat better, so when your heating is off, the walls continue to heat the home, resulting in a more even temperature and reducing the possibility of dampness coming through the walls. If you have existing damp issues we can often rectify these before we install your new insulation.

With this type of insulation, it’s possible to achieve almost complete coverage of your home’s exterior.  This minimises heat leakage in areas that are difficult to insulate using other methods, therefore it is a very high performing insulation.  It makes your house more airtight, removing chilly draughts, reducing the risk of condensation and mould inside, and also offers the additional benefit of increased sound proofing.

It also renews the outside of your home, improving appearance and, depending on the finish used, provides increased weather protection.  Best of all, there’s minimal disruption to your daily life.

External wall insulation is available with a variety of finishes and colours, allowing you to improve the overall look of your home.

How Do I Know If My House Requires External Insulation?

If your home was built before the 1930s, more than likely you have solid walls, so you will not be able to get cavity wall insulation, so external wall insulation would be a better choice.

If your house was built after the 1980s you probably have cavity walls, so cavity wall insulation would be better for your house.

If your house was built between 1930s-1980s, more than likely you have cavity walls, but there are other ways you can check.  If the size of the bricks is the same across your brickwork, you have cavity walls.  If you cannot see the bricks, check the thickness of the walls – if they are thinner than 32cm (12 inches) you probably have solid walls.  If you’re still not sure, contact us and we can advise you.

As an SEAI registered company, with over 16 years experience, we know how to make the insulation process as easy as possible for you.

Before we arrive, you should check if your gas or electric meters are attached to the outside wall of your property.  If so, you’ll need to contact your service providers to have them moved before we start work.

You will need to ensure that the exterior of your house is clear, ie remove window sills/reveals etc, and ensure that we have space to work outside your home.

  1. We attach insulated boards to the outer surface of your home using both an adhesive layer and mechanical fixings.
  2. This insulation is then covered with a protective layer of mesh.
  3. Finally an extremely durable and water resistant render is applied.
  4. We clean up after ourselves and leave you to enjoy your warmer home!

The work takes 2-4 weeks, depending on the size of your property and weather conditions.  All work is carried out on the exterior of your building, so there is no disruption to your daily life inside your home.  Neither are there any fumes to worry about.  However, you should be aware that this is building work and as such there will be some low level noise for the first few days.

Our insulation is attached to the wall using both adhesive and mechanical fixings in order to prevent the insulation coming loose and increasing longevity. We don’t interfere with your damp course as the insulation starts above it in order to avoid problems with damp.

You’ll feel the difference in your house overnight and best of all, there’s no special care or maintenance required for this type of insulation, it will take care of itself, with a guarantee of 25 years!

Please note that depending on the time of year we may need 2-4 weeks notice prior to installation.  External wall insulation cannot rectify rising damp coming from the ground as this is due to a faulty damp course.  This problem must be rectified by a specialist before we commence installation of your insulation.  We can arrange this for you if necessary.
