Launa Windows Ltd

I have bought a set of patio doors plus windows and a back door from them. Never again. The patio doors have leaked from day one despite someone coming out to try and fix it. The back door had a gap that the wind whistled through although they did eventually fix that. The real reason I won't use them again is what has just happened. The patio doors are on a converted garage. We were sitting just outside the house when, completely randomly, with no one else around the inner window of the sealed double glazing unit shattered. Launa response has been not our problem. The guy I spoke to was on the edge of rude saying they don't just break. Well Sherlock this did! However the 10 year warranty only applies to glass shattering in the first few week apparently so I will have to foot the bill. This was definitely not our fault but what has really put me off was his attitude. Customer service is not their strong point apparently.
