In Spain the question often arises which is the best material to use for windows and doors. Although each individual house or situation is unique there are certain constants which generally apply.


The advantages of PVC windows and doors are: excellent insulation values and the fact that many northern european countries are used to the feel and look of PVC.


On the down side PVC window sections can be bulky compared to slimmer, inherently stronger aluminium profiles, especially in certain situations such as bay windows, or sliding windows within arches for example, where the combination of profiles can become much more obtrusive in PVC.


Despite numerous rumours, the very best PVC profiles will not yellow or fade even in the severities of the Spanish climate.
Although at present in Spain aluminium is much more widely used, PVC is becoming a choice of material used more and more each year and as with all
