Thermally broken, aluminium, side-hung, top-hung, fixed or tilt and turn casement window system for heritage applications.
It is the ideal solution for heritage applications such as listed building renovations and large-scale replica-refurbishment projects where planning constraints are to be considered.
Thermally broken, aluminium, side-hung, top-hung, fixed or tilt and casement window system incorporating innovative polyamide thermal break technology, which creates a barrier between the cold air outside and warm air inside. This technology significantly reduces thermal transmittance and enhances the overall U-value of the product.
Alitherm Heritage is available in a choice of standard and non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodized effect finishes.
The Alitherm Heritage 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 designed drip bar between modules.
