At sashwindows.ie we supply timber sash windows in a treated soft wood, with the trade name of “Accoya”. This timber is guaranteed against rot for 50 years and is well worth checking out on Google. We also supply the “Heritage” slim-line PVC sash window and an aluminium sash window called “Alutherm”
Replacement Timber windows
When replacing windows in a “Protected Structure”, it is now a requirement of planning law, that only designs, identical to the originals, can be used, once permission has been sought and granted by the Local Authority.
Even where there is no “protected structure” issue, many people are so fond of the ‘look and feel’ of timber, that timber it must be, whatever about the maintenance bother.
In “protected” buildings even the weights and cords must be reinstated. In less sensitive buildings a more modern spring system can be used, if required.
