All that aside - the thing that concerns us most right now is that it has just been discovered that the type of glass we have chosen for part of the glazed gable (Suncool glass) is not available at the size we need in a toughened state. Choices are currently:
- Prove that it is possible (my favourite solution). We're working pretty hard on this one right now.
- Find an alternative design which works within size limitations but does not compromise the design. (Not sure this is possible).
- Compromise the design (picture me now - kicking and screaming). This means either reducing the size of the window or breaking it up into smaller units. No no no.
Working on no 1 (scouring Pilkington website, multiple phone calls to Pilkington technical dept and other glazing companies) has surprisingly thrown up a few options which need some technical clarification. 2 key options being:
a. Get a specialist company to toughen the glass from Pilkingtons (there's a company in London called European Toughened 020 8961 6066 who can toughen glass of 3300 x 7000) then make up the double glazed units. Not quite as easy as it sounds because although Pilkingtons gave me their number, European Toughened cannot get the Suncool glass from them directly. We'd need to involve multiple parties.
b. Discover that it's only the inner pane which needs to be toughened because there's no access to the outside (it's out of reach and inside the building). Fingers crossed this one applies. Our structural engineer has been put on the case working out "barrier loads" so that Pilkingtons can advise accordingly.
I'm not sure that in my life I'll ever have my15 minutes of fame. I have however (perhaps more usefully) had my 15 minutes of being a glazing expert, a sanitaryware expert, a light fittings expert, an eco build expert, a water pump expert, a boiler expert, and underfloor heating expert, a Heat Recovery Ventilation expert (I've even got a certificate to prove this one!)... the list goes on. It's a shame after 2 children that my memory is shot to pieces - this knowledge might be useful again but alas... all gone in the 16th minute. Still - at least we'll have a nice house!
