Aluminium Window Systems

Smart Alitherm 300

This diverse array of profiles offers numerous solutions for residential and light commercial settings. They can be used to craft traditional casement windows that echo the grace and design of timber products, or to create modern-style windows suitable for contemporary homes or offices.

Alitherm profiles employ Smart’s advanced polyamide thermal break technology, which establishes a barrier between the cold exterior and the warm interior. This technology markedly decreases thermal transmittance, thereby improving the product’s overall U Value, aligning with the stringent standards of Document L 2010.

Alitherm products are available in a choice of standard or non-standard colours, including metallic & dual colour.

British Standard Kitemarked system KM 81580 KM 81543
The system features an extended polyamide thermal break which improves the overall U Value of the profile, allowing Alitherm 300 to achieve a Window Energy 'A' Rating when used in conjunction with the correct double or triple glazed unit.
The system is suitable for both internally or externally beaded, side or top hung open out windows.
Profiles have the option of either ovolo, chamfered or square edges.
Frame options for both standard and slim-line stays.
Option of either multi-point or cockspur locking handles.
