The AA®100 Curtain Wall is available as a standard 50mm system, or for increased loads and movement, our AA®110 65mm system, 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 or vertical capped. The AA®100 SSG system allows glazing of the curtain walling to be achieved without the use of conventional pressure plate and face caps, or for increased loads and movement, our AA®110 SSG system, now further developed to allow up to +/- 5mm building movement. The AA®100 and AA®110 CV is available as a top hung vent or parallel opening window, allowing flexibility and freedom to maintain flush seamless visuals externally, with no visible aluminium framing. 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 SL Slimline Casement designed with narrow frame sightlines to achieve a modern aesthetic look available in two styles, one offering a cost effective and robust solution for the Education Sector and the second a unique double flush external and internal aesthetic for the Home Improvement sector, the AA®720 Pivot, the AA®720 Tilturn and the AA®720 Parallel Opening. AA®720 FR consists of Door and Fixed Light variants offering 30 minutes insulation and integrity.

KAWNEER HEIGHTENS PERFORMANCE FOR THE UK’S FIRST PASSIVHAUS LEISURE CENTRE
With sustainable and responsible design being at the forefront of modern architecture, it’s no surprise that Gale & Snowden Architects chose Kawneer’s innovative aluminium glazing systems as part of the energy efficient design to transform St Sidwell’s Point into the UK’s first Passivhaus leisure centre.
Located in Exeter, Devon, this 6,700m2 project centred around the replacement of an ageing leisure centre swimming pool with an eight-lane national/county-standard pool and four-lane learner pool, both featuring movable floors.
One considerable façade challenge was to achieve an average 0.8 W/m2K and a 0.4 m3/h/m2 @ 50 pascals air leakage which exceeds the current building regulations. For the main glazed areas, two types of curtain walling and three types of doors were specified, as well as high performance windows and brise soleil. All were installed by Kawneer-approved specialist sub-contractor AB Glass on behalf of the main contractor Kier Construction.
Kawneer’s AA®100 HI capped curtain walling was used to create the distinctive building envelope and complement some internal locations, in addition to featuring RT®82 HI windows whose exceptional levels of thermal performance and airtightness helped to achieve the high building specification.
Both products meet rigorous energy efficient design standards and are Passivhaus-certified. These were complemented by Kawneer’s AA®190 TB external entrance doors, AA®720 standard and AA®720 HI doors internally and AA®130 brise soleil.
Benefits of the Passivhaus design include a 70% saving on energy costs when compared to a current ‘good practice’ leisure centre facility, a 50% reduction in water use, outstanding internal water and air quality, excellent daylight levels and lower maintenance costs due to a high-quality building fabric.
Nigel Harvey, Managing Director of AB Glass, said: “This is an innovative project that we have been very excited to be involved in. The environmental credentials of this building are such that we believe some of the standards and skills we have implemented here will be in high demand in the future as many more buildings look to emulate what we see here.”
As well as state-of-the-art swimming pools, new dry sports facilities include a gym, café and crèche, together with health and spa amenities. The flagship leisure centre in Exeter City Council’s £330 million city centre regeneration masterplan is expected to attract more than 500,000 visitors a year.
St Sidwell’s Point Leisure Centre has been shortlisted for ‘Building Project of the Year’ in the South West Constructing Excellence Awards 2022. Also for ‘Most Sustainable Building’ in the Façade Awards UK 2022.

KAWNEER IS PREPARED FOR CHANGE WITH THE NEW ‘APPROVED DOCUMENT L’ REGULATIONS
The thermal regulations for façade products will change from June 15th 2022, with U-value requirements and Window Energy Ratings being upgraded as part of the new Approved Document L. The changes are detailed on the Government website, and everyone within the UK construction industry needs to familiarise themselves with the changes.
Document L forms part of a larger set of guidance and rules for Building Regulations in the UK, setting the standards of how we design, build, maintain, recycle and operate. As a leading innovator, Kawneer is fully committed to changing practices to meet regulations and reduce its global impact.
The new Approved Document L will now be in 2 Parts, Dwellings, both New Build and Refurbishment will fall under Part 1, and all other Non-Dwellings fall under Part 2.
Why The Change? Increasing Performance to Reduce Emissions
Buildings currently in use are reported to be contributing around 40% of global carbon emissions. The UK Government has ambitious targets to help reduce emissions in both the New Build and Refurbishment sectors, including changes to the performance requirements of windows, doors and façade systems.
The plan to help reduce carbon emissions is being introduced in two phases. With the 2025 Future Homes Standard demanding that buildings produce around 75% less carbon than today’s levels, the interim changes made this summer will aim for a 31% reduction in carbon emissions.
There are also further updates to Approved Document F regarding ventilation of buildings and Document O relating to overheating, along with changes planned for the Scottish and Welsh Building Regulations.
How will Kawneer products be affected? Impacted not Compromised
Kawneer’s product portfolio is constantly evolving in line with industry changes. A wide range of products and solutions have been tested and thermally modelled to comply with the new Approved Document L.
Our window and door systems offer a range of thermal performance levels to give users choice in the specification to meet and/or exceed the requirements of ADL.
With regards to our curtain wall systems, as the framing materials tend to represent such a small proportion, typically
