What are the benefits of External wall insulation
There are a number of 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 buildings 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 houses get 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 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.
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 owners manual which comes with the manufacturers 10 year warranty.
So lets summarise the benefits of external wall insulation
- Less energy required to heat your home, thus lower fuel bulls.
- More balanced comfortable heat throughout your home
- Avail of the current government grants through Sustainable Energy Authority of Ireland
(SEAI)
- redecorate the outside of your house giving a new & fresh appearance
- Improve your existing Building energy rating
- No need to move out while the works are being carried out.
- Reduce existing mould growth problems and damp
- Cover up existing unsightly render / finishes and cracks.
- Internal area remains unchanged as the insulation is applied out side the home.
