The first level is Beginner, and free to view at: http://www.thewindowman.co.uk/misty-wood.htm I will not repeat that here, so please read up there first. Although aesthetically so very pleasing to the eye, unfortunately double glazed sealed units fitted in almost all wood windows and doors have a notoriously short life (6 or so years from new before failure is not at all uncommon). This is mainly to do with water ingress to the glass perimeter due to basic frame design inadequacies and wrong glazing techniques, together with a lack of adequate drainage. Also with close inspection I have observed that nearly all wooden windows I see have been left too long between maintenance intervals. Particularly I see gaps where water can get into the perimeter of the sealed unit, and I often see a small but noticeable gap between the glass and wood, through lack of maintenance and attention. If you have wooden windows, double glazed, I strongly suggest you 'pipe' a bead of clear silicone around outdoors, between the glass and wood, and seal any gaps in the wood joints as well. Checking and re-doing this at least every other year will prolong the life of your sealed units by possibly many years. Click the next line to read more about this subject:
