Senior Architectural Systems has launched PURe Window, a new aluminium framed window system. The product uses polyurethane (PUR) foam as its core insulation material, a technology gaining traction in the window and façade sector. The system targets architects and builders seeking higher thermal efficiency in aluminium windows. PUR insulation offers superior performance compared to traditional polyamide thermal breaks, with implications for U-value ratings and energy compliance on new-build and refurbishment projects.
