EXTERNAL WALL INSULATION (THE WRAP)

Did you know 35% of the heat in your home is lost through your external walls?

External wall insulation has the best results in keeping your house warmer for longer with reduced energy bills. It is also a proven fact that it improves the air tightness of your home which conceals the heat within the building envelope.


All houses built from block or brick will release the heat back into the home when the heating is turned off. External wall insulation causes no disruption to the living area of the property.


A cavity block should not be pumped with any insulation as it cannot guarantee that all the holes and gaps can be filled, which can cause huge problems with dampness.


External wall insulation is applied with equal amounts of insulations with layers of renders making it waterproof and airtight.

 

What is External Wall Insulation?

External Wall Insulation (EWI) is a composite cladding system comprised of suitable insulation and waterproof coating which is applied to all the external walls of a building.


The application of EWI reduces heating bills, and consequently, carbon emissions also.

 

EWI is the most efficient way to insulate an existing building. FACT! It uses the fabric of the building like a storage radiator. Because the heat can no longer escape through the outer layer of insulation, it is reflected back into the living areas, creating a constant warm home.


With up to 35% heat lost through external walls, EWI can help reduce your heating bills by up to 35%. It can also reduce your carbon footprint by cutting your CO2 emissions by up to 2.5 tonnes per year.

How is External Wall Insulation applied?

 

Step 1

The required type and size of insulation is mechanically and adhesively fixed to all external walls. This creates an insulation envelope that prevents heat loss and cold bridging, which can occur using other types of insulation, e.g. cavity fill.

Step 2

An alkali-resistant open-weave fibre mesh is embedded onto the insulation board using a polymer-modified cement basecoat. This provides both impact resistance and tensile strength.

 

Step 3 

A coloured primer is applied (by roller, brush or spray) to the base coat when fully dry. (Drying takes approximately 24 hours.) This aids adhesion/ water resistance, and also improves the colour uniformity on the final finish.

 

Step 4 

A low maintenance coloured and textured acrylic render finish is then applied (troweled or sprayed). There is an extensive pallet of colours and textures to choose from. The final result is a durable low maintenance finish that will only need hosing down to clean. 

What are the benefits of External Wall Insulation?

 

There are several benefits to external wall insulation, in fact any insulation upgrades if carried out properly will benefit both your standard of living and your savings. Generally, the more works you have done the more money you will save over the course of the building’s life.

 

As with most of the houses built in Ireland pre-2006 your house would probably be classed as under insulated, which basically means that your home is not retaining the heat. A good indication of this is when the heating is turned off, the house gets cold again after a very short period. By externally insulating your house you are insulating the larger surface area of your home where heat is escaping. Most houses loose between 35% to 45% of the heat generated through the walls. This heat could be retained for much longer periods by getting external wall insulation.

 

Some of our past clients to date have reported that they only have to use their heating for 1 or 2 hours per day compared with a previous heating times of 5 to 6 hours, that will result in less hours running time on your boiler and lower fuel bills.

So how does it work?

 

By externally insulating your home a layer of insulation wraps your walls and slows down the heat transfer from inside to outside, thus allowing a heat reserve to build up in the existing walls, much like a low temperature storage radiator. As the temperature drops this stored heat is slowly released back into the house. 

 

Recent client testimony

 

"Sean Og Construction completed external insulation and attic insulation at my house. I cannot speak highly enough of this company. The quality of the work completed was excellent. It has made a huge difference to the warmth of my house. I used to feel a chill when I walked into the house during winter but not any more, even if the heating is not on. They showed great attention to detail and I felt that they took pride in doing really good quality work. They were also extremely professional and reliable. They always arrived on site when they had said they would be there and responded quickly to any questions I had. I would not hesitate to highly recommend this company or to have them back again."  

Another benefit is a new look to your home with a low maintenance finish, which only has to be painted every 15 - 18 years. To keep it looking fresh, just apply a light power wash as instructed in the supplied home owner’s manual which comes with the manufacturers 10-year warranty.

 

So, let's summarise 10 benefits of External Wall Insulation...

  • Less energy required to heat your home, thus lower fuel bills.

  • More balanced comfortable heat throughout your home

  • Avail of the current government grants through Sustainable Energy Authority of Ireland (SEAI) up to €6,000 for EWI

  • Redecorate the outside of your house giving a new and fresh appearance

  • Save on external maintenance and painting

  • Improve your existing Building energy rating

  • No need to move out while the works are being carried out as the inside of your home is not affected.

  • Reduce existing mould growth problems and damp

  • Cover up existing unsightly render/finishes and cracks

  • Increase the value of your home
