So would you have white very thin curtains, almost see-through, or would you go heavy white linen touching/folding on the floor?

I think curtains mounted on the wall would be pretty and give a softer effect. When you want new windows, do have a look at our 22 members - all have to make their wood windows to our exacting criteria. The frames can be expected to last around 60 years, and they won't need a lick of paint for 8-10 year.

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...
