FGS Heritage 47 Slim Frame Windows
FGS Heritage 47 Crittal Replacement Window System
This slim window system has been designed to offer a modern solution for heritage and renovations applications where the requirement to replace old steel windows is essential.
FGS Heritage 47 provides the ideal solution for heritage applications such as listed building renovations and large-scale replica-refurbishment projects where planning constraints are to be considered.
It is a high-performance window system with innovative polyamide thermal break technology which creates a barrier between the cold air outside and the warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U Value of a product and is designed to meet the exacting requirements of Document L 2010.
The window is designed to be built as a series of horizontal modules which can be stacked using horizontal couplers to form a multi-part window featuring a specially design drip bar between modules.
FGS Heritage 47 has been tested to PAS 24:2012 for casement windows and fixed lights.
