ST70 Tilt & Turn

The ST70 super performance Tilt and Turn window system uses unique eco-friendly polyamide core allowing it to achieve an excellent thermal performance whether the window is used in an open in or open out configuration. The versatility of the locking mechanism used in this window system allows a design team to incorporate extra large sashes into a façade or window. By using a centre seal gasket in all window types the designer can be assured that air leakage rates are significantly lower than the required industry standard of A3. Along with the ST80, the ST70 window system was independently tested to comply with the most up to date and rigorous test regime - BS6375 part1 & part 2. This test pays critical attention to air leakage under both positive and negative pressure cycles, ensuring thermal efficiency.
