All Stirling units can be fitted both horizontally and vertically and are available in standard form for pocket glazing into all 24,28, 32 mm curtain wall and roof glazing systems. In addition, various flanges are available to allow integration with non-glazed composite structures.


In developing the Stirling we have created a product which in itself is a system. It is easily extended and adapted to integrate with modern curtain wall and roof glazing systems and to all other forms of structure – be it stone, brick or cladding.

The product can blend into building structures whilst maintaining the highest specification standards. This affords the designer creativity in the use of high performing, thermally efficient products. It has been specifically designed to meet the both functional aesthetic demands of the modern construction industry and provides the perfect blend of performance, versatility and aesthetics.
