Answer. When you choose pre-finished wooden windows, the lifspan of the paint work will mainly depend on the type of timber used in construction. Obviously the exposure of the building and whether or not the units receive any maintenance and cleaning will also have an effect on durability.
Factory finishing ensures an even and comprehensive covering of paint which cannot be achieved on site and provides peace of mind that all aspects of the window are protected from the elements.
Paint warranties on timber sash windows and doors are as much as 12 years on Accoya, 10 years on hardwood Sapele Mahogany and 8 years on laminated softwood. Depending on conditions the paint finish may last even longer. See this link for a case study of a Kingsbridge Joinery project – (Pre-finished sash windows, 10 years later)
When the time comes to re-paint, micro-porous paints are much more user friendly than the old gloss paints of days gone by.
