Alitherm Heritage | Steel Replacement
-
Alitherm Heritage is a range of Aluminium Windows and Doors design specifically for heritage applications such as conservation areas, listed building renovations and large scale replica-refurbishment projects where planning constraints are to be considered.
The versatile Heritage range of Windows and Doors can be used for all refurbishment, new-build projects or extensions as both internal and external doors.
The window system 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 replicating a traditional steel window.
Alitherm profiles utilise Smart’s 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.
Alitherm products are available in a choice of standard or non-standard colours, including metallic, dual colour, Smart Architectural Aluminium Sensations textured, and Alchemy anodised effect finishes.
