High Quality Energy Efficient Glazing from Rationel Windows and Doors Ireland


At Rationel Windows and Doors Ireland, our alu clad windows are at the very forefront of energy optimising technology, as can be seen in our AURA and AURAPLUS ranges. So good are they at maintaining a comfortable indoor temperature that they meet all Passive House criteria, the global standard on supreme energy efficiency in construction.


Argon Gas
Each of our replacement windows are manufactured to include a gap between the panes that is filled with argon gas and a warm edge spacer. This thermal break prevents the majority of the heat loss that occurs around the perimeter of the pane, a leading cause of energy loss in standard types of double glazed windows. This is helped further by the fact that the panes in our aluminium windows can make use of solar heat coming in, hugely reducing the need for heating to be used during the colder months.


Substance and Style
This optimised energy efficiency of our composite doors and windows does not come at a cost of style, as the AURA line offers a sophisticated, modern aesthetic to any home they are installed in. Also available in variety of different opening functions and attractive hardware, every element has a virtuous uplifting effect on both the look and value of your home.
