The Dualframe 75 Si Reversible aluminium window provides access to the exterior face of a vent from inside the building.
This window system effectively rotates through 180° outside of the building line allowing easy cleaning of the aluminium window frame and the glazing.
Using advanced polyamide thermal break technology, the Dualframe 75 Si Reversible aluminium window provides exceptional thermal performance without the need for costly and complex sealed unit specification.
Dualframe 75 Si Reversible Windows are designed to rotate on the exterior of the building, without interfering with interior design elements such as blinds and other fixtures. This makes them ideal for cleaning from the inside without impacting valuable internal space.
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.

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.
Eastside Locks is a 17-storey student accomodation block located in the heart of Birmingham. High-performance windows and doors from Technal have been incorporated into the off-site, modular design.
This £30 million construction at No. 1 City Locks is on what was a brownfield site alongside the Digbeth Branch Canal and forms part of the city's long-awaited Eastside Regeneration Project. Working in co-operation with Sisk Construction, Glenn Howells Architects and Elite Aluminium Systems Ltd, Technal won this project by 'value engineering' the original curtain wall design.
By re-evaluating the project's technical, logistical and budgetry challenges, a Dualframe 75Si window wall specification provides a cost-effective solution which could be pre-fitted into the precast concrete modules that make up the building's elevations. This solution also enables any replacement glazing and maintenance to be done from inside, which isn't possible when using conventional curtain walling. This project also features the use of Technal Elegance 52 ST curtain walling to enclose the stair towers, and STII thermally broken commercial doors for main access routes.
Project Architect David Hickman commented: “We are really pleased with the building overall, while the windows work really well both in terms of their colour and their proportions in the tower. We opted to go for the full height frames which means as soon as you enter into the student rooms they give a really good connection between the inside and outside of the building; and great views over the city.
“We have worked with Technal previously, including the student and wider residential market. In this instance the idea of a modular solution and installing the Dualframe assemblies at the precast plant evolved during the tender submission process, and proved very effective.”
