The average life of a sealed unit should be 10-15 years, its what they are all tested for ( providing the manufacturer has a licence to manufacture them....yes a licence)
But there is a caveat to this, it depends on the glazing system and how well its glazed. For example no one will warranty a sealed unit in putty , a lot of places won't warranty sealed units in wooden frames ( we, however offer 5 years if glazed with a recognised way ) but in PVc and Aluminium it should be a warranty of 10 years regardless. I dont know any sealed u it manufacturer that doesn't offer 10 years

Interesting. Something I think I'll look into. Not sure how I get to see his licence though without p1ssing him off. Is there a register?
