What is External Wall Insulation?

External Wall Insulation Systems are an extremely effective method of improving the energy efficiency of your home and increasing the capital value of the home itself. It is a cladding system for exterior walls that is light weight, flexible, dynamic and extremely durable.

External Wall Insulation involves fixing insulating materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. The insulation is then covered with a special render to provide weather resistance. A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance. There is a significant selection of colours and finishes to choose from.

External Wall Insulation systems provide the following benefits

  • Reduces unnecessary heat loss and CO2 emissions
  • Reduces and usually eliminates condensation, mildew & fungal build up
  • Low maintenance, no painting required, Colour stability/fade resistant. Extensive range of colours, stone / brick effect possible
  • Durable and crack resistant. External insulation protects and prolongs the fabric of the building offers extraordinary rain and impact resistance and all all external insulation provided by EnergySolve comes with a 30 to 60 year guarantee
  • Cost effective

Cost effectiveness is a relative term. External wall insulation is a significant upgrade to the structure of your home and consequently imposes significant cost. This cost should be measured relative to:

  1. Payback period; typically between 8  & 12 years
  2. Capital appreciation of the home; much, if not all of the expenditure is immediately recouped through capital appreciation of the value of the home
  3. Energy Savings: 40% savings on heating costs

Externally insulating your home results in a sustained positive environmental impact for you and your community. We’d like you to choose us to help you make a lasting environmental difference in world we live in. Contact us

Will the EWI increase the value of my Home?

Yes, significantly. You can expect to see a commensurate appreciable increase in the value of your home through External Wall Insulation Systems. Remember, not only does it make your home more energy efficient; it also gives you a completely new external wall. Consequently the external aesthetics of your home can be upgraded or refreshed.

Is there Grant Assistance available?

There is substantial (up to €4,000) worth of Grant Finance available for external insulation works. See our Grants page for more information on funding of energy efficient projects.

External Vs. Internal Insulation

The use of external, rather than internal insulation offers a number of practical advantages:

  1. There is little or no disturbance to the occupants and the possible additional cost of temporary re-housing is avoided.
  2. The problems of insulating internally around or behind internal fittings e.g. in kitchens and bathrooms, but also cupboards, shelves, power points etc. are avoided.
  3. Potential cold bridges at all internal/external wall and ceiling junctions are reduced or eliminated.
  4. In a complex building, it is comparatively easier to ensure that the whole of the external surface is insulated.
  5. The whole wall structure is protected so external surfaces are prevented from receiving further deterioration by being exposed to the weather.
  6. Internal condensation problems are alleviated and comfort levels are improved.
  7. The external appearance is improved markedly and whole estates of sub-standard dwellings can undergo a remarkable face-lift with all its consequent social and political benefits. Finally, the whole building obtains an additional structural protection which may significantly increase its expected life.

There are a number of ways in which wall insulation can be increased and improved. The payback period will depend on a number of factors including type, thickness and quality of existing insulation.

Insulation Upgrade Works | EnergySolve

Remember that people expect your house to be well insulated, but an externally insulated home can expect to see a commensurate capital appreciation in the value of the building. While Internal insulation is really a necessity for every home it does not it does not lead to an appreciable capital value of your home as does External Wall Insulation.

Roof Insulation | EnergySolve

If the insulation in your attic is made from wool (fibreglass, sheeps wool, rock wool etc), is it less then 300mm thick. Do you find the house loses heat quickly once the heating is turned off.

Wall Insulation | EnergySolve

If you answer yes to all or the majority of these questions it would be beneficial for you to consider. If you already upgraded your insulation, was the upgrade carried out more than 5 years ago. Do you find the house loses heat quickly once the heating is turned off.

Attic | EnergySolve

Consequently drafts and moisture damage the insulation over time, forcing gaps and damaging the material itself. Attic insulation is traditionally designed to prevent heat loss but not to protect from wind and draft. Grant aid is available for attic insulation.

Windows & Doors | EnergySolve

All windows and external doors should be checked for draughts and, if necessary, draught proofed to reduce heat loss. 10% percent of heat loss of the average home happens through windows and 15% through your door. Double and triple glazing is available and heat recovery units are highly recommended. Contact EnergySolve for more info.
