The Alitherm 300 series offers a range of high quality glazing solutions for side and top hung open out windows.

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

• 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.

Alitherm also provides the option of either multi-point or cockspur locking handles.
