Rationel will organise for the windows to be fitted for you as part of the price.
We used them in our house and they are lovely windows and I can recommend the company.
The sales manager I dealt with was called Paul Johnson, I think he may cover Limerick, I don't have his number handy but I'm sure you can get it from their office.
Incidently even though it is a Danish company the windows are assembled in Edenderry, so I suppose you could say its an Irish product!
Cheers
