Windows in the Ideal House needed to comply with a raft of performance criteria to meet Passivhaus and Homestar requirements. Warm Windows supplied UPVC joinery that meets all these criteria, which include a set level of airtightness. The temperature on the windows is maintained so there are no cold spots of less than 17°C when the outside temperature is -3°C and the interior 20°C. And the glazing U-Value is no more than 1.30. To achieve these standards, Aluplast GmbH Ideal 8000 joinery was specified. This joinery has a six-chamber profile with an external flange subframe and liner and a centre gasket system with three sealing levels. The joinery is triple glazed with ClimaGuard Solar 67/27 insulated units featuring low-e glass. The hardware reflects a similar high degree of technology. Doors are fitted with Germanmanufactured Dr Hahn hinges, capable of carrying a 250kg load, while the high-end tilt and turn window hardware is by Winkhaus activPilot, with Hoppe Secustik® handles. Warm Windows provides a complete range of UPVC joinery, ranging from standard residential to Passivhaus designs.
