DUALFRAME 75 Si

High Performance Casement

Simple, Streamlined Aesthetics

Characteristics

The Dualframe 75 Si Casement 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.

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, 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 project team responsible for a striking residential property in the Channel Islands have used Technal’s Dualframe 75 windows and the Elegance 52 curtain wall system, supplied by Pallot Glass & Windows, to match the property’s modernist styling, as well as to provide outstanding weather performance in a very exposed situation.

Verde, Newcastle

United Kingdom
A total of 770 windows feature on the Newcastle’s student accommodation, Verde. This is the fourth and final phase of the £250 million Downing Plaza development - the largest planning application to be granted in Newcastle for a generation. Located on the former Hill Court Site, designed by award-winning architects SimpsonHaugh, this striking landmark set a new standard for student living in Newcastle.

Stapleton House, London

United Kingdom

Stapleton House is a design and build project by Balfour Beatty Construction Services who created 862 high specification student spaces across nine floors in the large and logistically challenging student accomodation project in North London. 

The property is located by the very busy Holloway Road and therefore needed an enhanced acoustic rating for each elevation facing the public highway, as well as the achievment of high thermal, weather and security standard throughout. 

The fabricator Sealtite, along with the Technal UK technical support team duly delivered a proposal of Elegance 52 curtain walling and the Dualframe 75 Si windows and provided detailed drawings, strength calculations, thermal calculations and information on acoustic testing. 

 

Ysgol Penyffordd, Wales

United Kingdom
Selected for their weather, thermal and security performance, TECHNAL aluminium curtain walling, windows and doors was specified and installed at Ysgol Penyfford - a £7 million-pound primary school located in the Flintshire villlage of Penyfford in Wales. This project has been constructed to BREEAM Excellent standards.
