Hi-Tech Glass, with the touch of a Button

Times Online: Many new projects are incorporating technically advanced glass, such as panes with the ability to turn from clear to an opaque milky white at the flick of a switch. The laminate in Blink glass contains liquid-crystal polymers, connected to an electric current.
When the current is on, the liquid crystals are clear, but when it’s turned off, the UV-filtering, high-insulation panes take less than a second to switch to privacy mode (£1,000-£1,500 per square metre, including installation; 0845 290 3107, blinkglass.com). Cantifix, a firm that specialises in structural glazing, has been using Blink intelligent panes in projects from sliding doors and bathroom walls to entire glass extensions.
The newest smart products to reach the UK are glazed units called Eglas. Developed in Finland for marine use, they have built-in heating components that stop condensation and save energy by allowing the homeowner to turn down the central heating.
Eglas came to the UK this year and is already a hit with self-builders. The New Build Group UK is pioneering its use in combination with high-insulation products in its eco-developments, with radiant heat from the windows as the primary heat source.
