ST80 Casement
Our ST80 outward opening casement window is available in a variety of styles such as top hung or side hung and can be externally or internally beaded. All styles include multipoint locking for added security. The versatility of the locking mechanism used in the ST80 window allows the designers to incorporate extra-large sashes in the building.
The use of thermally efficient polyamide core for the ST80 Window and a glazing capability up to 52mm while maintaining an identical sight line throughout thus allowing you to value engineer a project from elevation to elevation or even floor to floor to ensure specification compliance, budgetary constraints, and aesthetic appearance are never an issue.
The windows durability and performance characteristics regarding acoustics and weather tightness meet with the highest BS/EN standards including PAS24 standards and are all independently tested by a UKAS approved and certified facility.
