Thermally broken aluminium, ‘French mullion’ casement window system.
All general light-use applications, including light commercial.
Thermally broken aluminium, ‘French mullion’ 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 800 Flush Casement is available in a choice of standard and non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodized effect finishes.
