According to Sapa, their Dualframe 75mm Si Tilt Turn window suite was the first in a new generation of double glazed aluminium window and façade products. Utilising advanced polyamide thermal break technology, Sapa’s powder coated Dualframe 75mm Si tilt and turn aluminium windows provide high thermal performance without the need to resort to complex and costly sealed unit specifications.
Drawing from the tried and tested design principles of their Dualframe aluminium casement windows, the Si designation will be progressively rolled out across all of the main Dualframe window and façade configurations. Tilt and turn windows are an ideal solution for high rise or commercial applications, combining ventilation with easy cleaning facilities and the opportunity to have large span openings.
Dualframe 75mm Si aluminium tilt and turn windows have a unique operating action that minimises the risk of damage to the product or injury to the operator. The handle is key operated and the key must be fully inserted in order to access the turn mode. Once the window is closed, it automatically defaults to the tilt only mode. Hinges are concealed within the aluminium frame, which removes colour matching issues and prevents a clash with plaster lines. Flush vents and flat profiles combine to create a simple and streamlined appearance, whilst an 88mm sight line maximises viewing area without compromising the U-Value of the window.
This powder coated double glazed aluminium tilt and turn window system can offer both tilt and turn, as well as fixed lights, including frame couplers and curtain wall interface. The window systems external beading requires no additional components to comply with BS7950. The product delivers excellent weather performance for water tightness, air permeability and wind resistance. Because the system has tailed gaskets and centre seals, it reduces thermal radiation and means that costly foam inserts into the profiles are not required.
