The Dualframe 75 Si aluminium window system from Sapa is currently our best selling window system. Its superb thermal efficiency rating coupled with its excellent flexibility have proved popular across the commercial glazing sector. The specialised profile range provides outstanding versatility. It is perfect for creating windows which combine inward and outward facing rebates without coupling sections or dummy frame to fixed lights.
The Sapa Dualframe 75 Si is universal in its design. It can be used to create a range of complex screens. Casement windows, tilt before turn, pivot, and reversible opening lights can be combined and furthermore, the windows can be either externally or internally beaded depending on your project specifications.
Why choose Dualframe 75 Si
The Dualframe 75 Si window system is designed to meet all industry regulatory requirements. To ensure that your project complies with all necessary regulations, the Si window system is:
- Building Regulations Part L compliant for thermal insulation
- BSI Kitemark accredited to BS4873
- PAS 24 security certified
- A + Window Energy Rated
- Capable of achieving U-values as low as 0.9 W/m²K
- Green Guide BREEAM A+ rated for commercial windows
Dualframe 75 Si windows also achieve high levels of resistance for weather performance. They are rigorously tested to ensure excellent water tightness, air permeability, and wind resistance. Their focus on creating an energy efficient building system will help to lower any building’s carbon emissions and reduce energy consumption.
High performance and attractive aesthetics
Sapa Dualframe 75 Si windows achieve such high levels of performance through their innovative construction. During fabrication, thermal breaks, gaskets, and seals are used to remove the need for expensive foam filled profiles. This helps to reduce production cost and the modern technology boosts the window’s performance.
In terms of their visual appearance, Dualframe 75 Si systems can be finished in an extensive range of powder coatings which are durable and low maintenance. All Sapa systems can be dual coloured to create a contrasting look on the inside and outside of the building. When used to construct large glazing screens, they create a stunning visual aesthetic to any commercial building.
