Introducing Kawneer’s AA®190 Severe Duty Welded Door
An entrance door with class-leading thermal performance that is so robust it is offered with a lifetime guarantee.
Kawneer’s AA®190 TB pre-fabricated door features welded corner construction – the strongest aluminium door construction available, with each corner having four separate weld points, each of which has a ‘lifetime guarantee’. Rigorous testing has verified its exceptional strength and durability, making it suitable for use in severe-duty applications as defined in BS 6375-2: 2009.
With regards to weather performance, the system has Class 2 (300 Pa) air permeability, Class 3A (100 Pa) watertightness and Class C2 (800 Pa) wind resistance, results that are based on an open-in double door with butt hinges and rebated threshold.
It is an all-purpose door for use in high-traffic areas and automatic entrances, it is as suitable for internal as it is external applications, for refurbishment as well as new-build, and for all sectors, particularly education, healthcare, commercial, and leisure and retail. With security hardware it meets Secured by Design criteria.
The door is designed to accept glass units up to 43mm thick, with a maximum leaf weight of 120kg with an overhead closer and a maximum of 200kg using the floor closer, all with leaf sizes up to 1320mm wide and 3000mm high.
As well as its high strength and robust properties, the AA®190 TB door also provides improved thermal performance. A whole-door thermal transmittance of Uw = 1.7 W/m2K can be achieved with a glass centre pane of Ug = 1.0 W/m2K.
The AA®190 TB door is offered with a finger guard pivot stile as standard, providing child-friendly reassurance, and is independently tested to PAS 24 for the enhanced security performance of single and double-leaf external doors, the enhanced security is available for both pivot and butt hung doors which can feature panic hardware.
A range of multi-point lock options provides security solutions for all applications including panic doors and electronic access control. There is also a range of thresholds including drained low thresholds compliant with the Equality Act 2010.
For ultimate design flexibility the AA®190 TB door is available as single-leaf and double-leaf in open-in, open-out and dual-action swing doors suitable for automatic powered operation. Additionally, the AA®190 TB door can be used with automatic sliding or bi-parting entrance systems.
Naturally, the door is available with its own thermally broken framing system – 451PT, which suites with other Kawneer fenestration solutions and all door options are available in an extensive range of single or dual-colour finishes.
Kawneer glazing systems help bring spectacular aesthetic to a new London HQ
Kawneer glazing systems help bring spectacular aesthetic to a new London HQ
Manufacturer's parallel opening window vents feature at the Anna Freud Centre.
Parallel opening window vents by leading manufacturer of architectural glazing systems Kawneer were specified for a mental health project that is arguably without parallel.
Some 88 of Kawneer's AA®100 SSG parallel opening vents were used as concealed windows, to maintain the same aesthetic as the façade, within AA®100 mullion-drained curtain walling and AA®720 doors on the new £40 million London headquarters of the world-famous Anna Freud National Centre for Children and Families.
The Kawneer systems were specified by architects Penoyre & Prasad as they were a "cost-effective" solution to their needs and enabled them to use the same systems for all areas of curtain walling and rooflights.
Architect Sam Frankland said: "We had an aspiration to create a very clean, paired-down façade that would give clear cohesion to the various buildings. Having scissor-action windows helped emphasise the planar quality when the windows are open."
The project has enabled the relocation of the mental healthcare charity to bring together its global expertise in practice, research and policy under one roof from its residential properties in Hampstead to a purpose-built facility near King's Cross. This comprises a six-storey new-build and the refurbishment of a century-old former chocolate factory and warehouse.
All of the Kawneer glazing systems feature a diagonal frit on the glass, with the Kawneer curtain walling featuring on the ground to top floors and the AA®100 SSG parallel-opening vents on all but the ground floor. The AA®720 doors feature on the main entrance and top floor which also features a roof terrace.
Sam Frankland added: "We wanted to create spaces filled with light and views out over London so we opted for fully-glazed panels with a simple frit to give an element of privacy and a degree of visual interest to the façade."
The aluminium Kawneer systems were installed over eight months by a team of six from approved specialist sub-contractor/dealer JPJ Installations for main contractor Willmott Dixon.
The charity that today bears the name of Sigmund Freud's sixth and youngest child was first established almost 70 years ago and its approach, that every child and its family should be at the heart of the care they receive, working in partnership with professionals, has been reflected in Penoyre & Prasad's design.
This needed to be striking to reflect the charity's aspirations to reflect its status as a world-renowned organisation working with eminent academic institutions as University College London and Yale.
This itself presented a challenge, bringing together the multiple needs of the individual users of the building, from children and their families in need of support, to researchers, clinicians and internationally-renowned visiting academics attending symposia.
At the front, in the space made vacant by the excavation of a former courtyard, is the new six-storey building housing shared conference facilities and the Pears Family School which is sponsored by the Anna Freud Centre. This caters for up to 48 youngsters who have been excluded from school or alternative education provision and helps them return to mainstream education.
Penoyre & Prasad worked from the outset with the diagonal motif on the glazing on both the front and rear facades to inform both the transparent elevation and the precast cheeks of the building which they could do very little with as they were both party walls but which nevertheless replicate the diagonal fritting.
The five-storey chocolate factory, parts of which had been used as offices since the 1990s, was converted into a combination of head office facilities and therapy, post-graduate teaching and research (part of which had been based at University College London) and break-out spaces for the Anna Freud Centre.
Although not listed, heritage officers at Islington Council had still been anxious about how it would be developed.
"The client was very keen to have as environmentally friendly a building as possible so aluminium seemed like the natural choice for the curtain wall system which has been used extensively to the east and west facades and as a large rooflight," said Sam Frankland.
Based on the established Kawneer AA®100 SSG POV system, the parallel opening design benefits from excellent ventilation characteristics combined with thermal performance.
Increased air flow around the full perimeter of the window enables highly efficient natural ventilation while greatly reducing draughts as fresh air is drawn in the bottom of the window while warm, stale air is expelled via the top, creating full air circulation within a room.
This efficient exchange of air can assist with Approved Document F compliance and can enable the window to meet the ventilation requirements of even the most demanding project.
