Costello Windows latest patented design is the Townhouse Sash Window. This window is designed in the style of a sliding sash window but opens in a different way. The Townhouse Sash Window does not slide up and down but rather the top sash opens out and the bottom sash open in. This gives full fire escape access and ensures that the window has a compression seal, making it airtight resulting in a high energy rating.
The Passive 100 Window has set an industry high for profile depth with a 100mm rebated window system. The triple glazed glass unit size is also an impressive 60mm. The uPVC window profile has 8 chambers, a first in uPVC Passive window design. These superb design characteristics give the Passive 100 Window its excellent thermal insulation properties and superior strength.
