The AA®100 Curtain Wall is available as a standard 50mm system, or for increased loads and movement, our AA®110 65mmsystem, now further developed to allow up to +/- 15mm building movement. By providing a unique dry jointed facade solution both systems can be installed as fully capped, horizontal capped vertical capped or structural silicone glazed. For Fire Resistance, the AA®100/AA®110 FR is designed as a stick curtain wall assembly offering 30 minutes insulation and integrity.
AA®201 Unitised Curtain Wall is a structurally glazed system along with our AA®265 Unitised System, a dry glazed solution incorporating a 3-chamber system and overlapping gasket design for optimum weathertightness. Both systems give the building team a unique set of benefits, including, factory fabrication to ensure additional quality control, rapid onsite installation as well as slimline design and flexibility.
Kawneer’s Curtain Wall, Window and Framing systems can accommodate our AA®130 Brise Soleil System which adds a stunning design statement to the building facade; optimising the natural daylight within a building whilst limiting the solar heat gain.
The AA®720 series corresponds to the BRE Global Green Guide online generic specification for windows and achieves a summary rating of A*. The windows are a 72mm profile incorporating the very latest thermal technology and meet the latest European requirements for thermal performance. Glazing and panels up to 56mm thickness can be accommodated enabling the use of triple glazing. The range consists of the AA®720 Casement, the AA®720 Pivot, the AA®720 Tilturn and the AA®720 Parallel Opening.

Kawneer glazing systems provide a sweet-looking façade
Kawneer glazing systems provide a sweet-looking façade
Curtain walling, windows and doors by Kawneer feature for British Sugar’s parents.
Architectural glazing systems by leading UK manufacturer Kawneer were specified as a “key aspect” of the new regional head office of British Sugar’s parent company, the FTSE 25 Associated British Foods (ABF), for their pedigree and quality.
CPMG Architects selected products from all of Kawneer’s portfolio for the building on a 4.5-acre site at Cygnet Business Park, Hampton, Peterborough, which would enable the relocation of almost 400 people from ABF businesses locally (AB Sugar, British Sugar, AB Mauri, ABF Ingredients and ABF) with the addition of purpose-built conference and training facilities and a showcase central reception area.
Kawneer’s aluminium AA®100 SSG (Structurally Silicone Glazed) curtain walling features on the ground floor reception, meeting/conference spaces and south-facing restaurant/café while AA®100 mullion-drained curtain walling has been used on the first and second floor open-plan offices of the three-storey building.
In addition, the 5,755m2 (GIA) building features ultra-thermally efficient AA®720 doors, large (3m high by 9m wide) AA®3572 sliding doors and over-sized (2.4m by 0.7m) AA®720 parallel opening windows, all installed over six months by a team of up to 15 from approved specialist sub-contractor Norman & Underwood.
The office spaces revolve around a triple-height atrium where a feature accommodation staircase connects the three floors to promote interaction and collaboration with 400+ staff, while skylights at roof level provide additional natural light and ventilation deep into the plan.
The ground floor is slightly recessed from the perimeter line of the floors above, eliminating the need for an external solar shading system. A prominent cantilever canopy above the protruding reception area emphasises the main entrance.
The design brief called for a building in keeping with ABF’s values of cost effectiveness and value for money, a “modern building fit for 2030 and beyond, with timeless / classic design and natural light and views out to the surrounding area as a key deliverable in the design philosophy”, all relating to health and wellbeing for the end users.
Precedents were considered in which contemporary office buildings use glazed curtain walling in combination with external glazed shading systems to optimise natural light deep into the building, minimising artificial lighting and glare from the sun, and enhancing the wellbeing of occupants.
In terms of the development of ABF’s new regional HQ, the aim was to create an environmentally responsible building, with an exemplar approach towards low-energy (PassivHaus) design principles. This involved energy demand minimisation through effective building form and orientation, good envelope design and proficient use of services, such that the building itself is used as the primary environmental modifier.
The construction over 20 months by main contractor Bowmer & Kirkland was of in-situ concrete where the exposed concrete also acts as thermal mass in compliance with PassivHaus design principles, as ABF was designing for an “A” energy efficiency rating to potentially help save £350,000 in combined running costs.
The entirety of the building envelope is Kawneer’s curtain wall systems with 50mm sightlines and consistent size modules that also incorporate sections of openable floor-to-ceiling windows to allow for a degree of personal control of ventilation. The objective was to create a visually open transparent façade to all elevations, maximising natural light into the building.
CPMG associate Ajay Chauhan said: “The Kawneer systems fitted the purpose of the building in terms of the size of the units and the thermal requirements, all of which were key elements for the building’s aesthetic we wanted to achieve, and Kawneer have been around for a long time and are defined as a quality product.
“The glazing is a key element as it allows natural light and ventilation to penetrate deep into the building while allowing users to have views out - all key elements that support health and wellbeing in an office environment. The building is completely a glazed box so the specification of the glass, in unison with the vertical glazed external brise soleil, was a very important factor in achieving a very energy efficient building.”
He added: “Kawneer provided a natural anodised finish, large glazed areas with corner glazed units and large ground-floor sliding doors which are amazing for end users to open the café/restaurant up to the external spaces.
“The clients are very happy with the end result as the overall building exceeded their expectations by designing an energy-efficient office building with collaborative spaces at the heart of it, and forming different agile working areas with controlled natural light deep into the building.”
Kawneer launches a one-stop-shop window solution
LouvreShield provides ventilation and fall protection for tilturn windows.
A louvre system which provides tilturn windows with fall protection and added ventilation has been launched by Kawneer, the leading UK manufacturer of architectural glazing solutions.
LouvreShield has been designed to suite with Kawneer’s super thermally efficient AA®720 and AA®543* open-in windows to give specifiers and contractors design flexibility and total project solutions – a one-stop-shop of aluminium glazing systems and louvres from one manufacture.
The system is surface mounted onto the outer frame of the window to allow free air movement into the room when the windows are operated in either the tilt or turn modes. And it also acts as a safety barrier when the windows are operated in the turn mode in instances where fall protection is required.
Designed for use in domestic, retail, commercial and residential applications, including student accommodation, two blade options (horizontal and tilted) are available to suit specific building requirements and optimise façade aesthetics.
A totally self-contained solution, LouvreShield completely eliminates the requirement for additional sub-contractor work and does not interfere with any other element of the building structure, whether it is new-build or refurbishment.
Manufactured at Kawneer’s production facility in Cheshire, the system comprises a cleated and pinned perimeter frame to which the louvre blades are screw splined, with all fixings concealed by clip covers. A wide range of PPC finishes are available with up to 30 years’ guarantee and anodised finishes with up to 25 years.
When installed to Kawneer specifications, LouvreShield is tested in accordance with BS 6180 (barrier loading) to 1.5 kN/m line load and to BS EN 13049 (impact resistance) Class 5.
*The AA®543 corresponds to the BRE Global Green Guide online generic specification for windows and achieves a summary rating of A+ for non-domestic schemes.
