Hi @User thanks for the thoughtful reply - all right on target. We bought the house with the newly installed windows, so the contract was with the previous owners - not us. Would be nice if Crittall would honour their guarantee or even offer any help but they've yet to do the decent thing. They will not toss their installer under the bus for mis-selling them, nor will they obviously go on record saying they're not suitable for a marine/coastal environment. We're happy to be their test lab!. With respect to condensation the thermal break question is a good one - thanks. If there is one it's not visible and seems woefully ineffective. We have trickle ventilation for the house as a whole but it doesn't reach the windows unfortunately. We do have all the usual extractors and we're starting to look at further air circulation/ventilation solutions. Cheers Bill

If you have wall lights on the pillars then you wouldn't be able to have one long pole, but I think that would look best and the most minimalist solution vs 3 separate poles. You can also get blinds fitted to the recesses of the door which can look really good as they're not noticeable when closed

Jonathan originally said taller crittall would look better than the shorter ones even if we had less of them Posted a pic again of the whole room layout for you @Emily. It will have a dark blue black shaker kitchen with suspended chimney extractor on cables and wood effect floor. I’ve seen industrial style kitchens with both crittall and wider bifolds and they both look nice. I would go with bifolds for the cost now because we have a max budget to spent on the house to ever get our money back (it’s not that we can’t afford to do what we want as such but you don’t want to throw money away!) even though I love the Crittall BUT it’s the practical side that we can’t agree on now

Hi Andrea We are an authorised dealer of genuine Crittall Steel doors and windows. The structural strength of steel allows very thin frames, giving a sleek and prestige look that is much sought after. Crittall thoroughly modernised their product moving to double glazed systems filled with Krypton gas for much improved thermal efficiency. During manufacture, the high quality steel is zinc-galvanised so it is rust proof, before powder coating in an extremely durable protective paint (so many colours available too!). The frames are fused together using a patented joint that ensures incredible strength throughout the system, and the frames are adjusted by hand using a team of highly skilled craftsmen that judge miniscule alterations to achieve a perfect product . The Crittall guarantee establishes confidence in a door and window system that will last a lifetime. No other steel window or door company goes to those lengths to provide such a high quality product. The quality of the steel, the galvanising, the craftsmanship... There really is no comparison, I assure you! Of course, all this quality comes at a premium price, and unfortunately many of our customers cannot meet the budget for such luxury. This is why we also offer an aluminium product that is similar in style. To even come close to the quality offered by genuine Crittall, we needed to offer our customers the best aluminium system we could find. We feel the Smart Alitherm Heritage range is the best alternative, and you can find an installer near you on the Smart website. Unfortunately Cornwall is out of our patch, otherwise I would urge you to come and view both the aluminium and steel products in our showroom. There you can see why genuine Crittall really is worth the price and why so many customers insist on the very best. I would like to wish you the very best of luck with your project and if we can be of any assistance, please get in touch. YES Glazing Solutions Photos show Alitherm doors and windows...
