Dualframe Si Casement

With an increased focus on the energy efficiency of buildings, it is invaluable to use windows and doors that help towards the overall reduction of energy consumption. The Si suite enables superior overall window performance to be achieved without the need to resort to complex and costly sealed unit specifications. The Si window suite can achieve an “A+” Window Energy Rating and where specified ‘U’ Values down to 0.9 W/m2K. As well as achieving exceptional thermal performance, the Si suite attains superior weather performance for water tightness, air permeability and wind resistance.

The specialised profile range adds great flexibility when constructing windows where inward and outward facing rebates have to be combined, without the need and expense of coupling sections or dummy frame to fixed lights. Universal frames can be used to create the most complex of screens easily combining casement, tilt before turn, pivot and reversible opening lights, as well as inside and outside glazing. Combined with the option of having different finishes inside and out, the Si suite will give you endless choices.

The Dualframe 75 Si Casement aluminium window uses advanced polyamide thermal break technology to provide thermal performance without the need to resort to complex and costly sealed unit specification. These excellent performance characteristics make the Dualframe 75 Si casement the ideal solution for today’s residential projects.

Our Si Casement window achieves a window energy rating of A+ as you would expect and also U-Values as low as 0.8 W/m2k. The aluminium profile creates a slim sightline which ensures maximum light floods into any building. Our PAS24 option is also available to ensure a Secured by Designed product
