Curtain walling, windows and doors by Kawneer feature on three refurbished tower blocks in West London.
Elements of the whole range of glazing systems by leading architectural aluminium systems supplier Kawneer have been used on three tower blocks at the heart of the refurbishment of a London borough.
Kawneer’s AA®100 mullion-drained curtain walling and AA®541 casement windows feature as vertical ribbons of glazing down the sides of the 24-storey blocks. The glazing systems were installed by approved specialist sub-contractor APiC UK for main contractor Breyer Group. The opening vents were designed as bottom-hung on electric actuators to complement a natural ventilation strategy.
They are complemented by Kawneer’s 451PT framing system, AA®601 top-hung casement windows and series 190 heavy-duty entrance doors (tested to the requirements of Secure by Design) on the ground-floor offices of Poynter, Norland and Stebbing Houses on the Edward Woods Estate in Hammersmith and Fulham.
All the Kawneer systems were polyester powder coated in a bespoke colour which was guaranteed for 40 years, while the outer panels of glass were toughened and the inner panels laminated to optimise solar gain.
The £16million refurbishment programme was designed by ECD Architects to improve living conditions for the residents of the three blocks which were built in the 1960s and were suffering from condensation, cold and noise.
In the process it has become an exemplar of sustainable tower block regeneration and a flagship renewable energy project for the inner-city borough.
The exposed concrete and brickwork panels of the three high-rise blocks, comprising more than 500 apartments, were cavity-filled and overclad to improve aesthetics as well as thermal and acoustic insulation to current Building Regulation standards. The post-war windows and doors were replaced with the Kawneer thermally-efficient and double-glazed solutions to enhance the overall performance of the building.
Add to these photovoltaic panels on the southern façade to generate approximately 82,000 kWh of electricity annually, solar thermal collectors, condensing boilers and nine-metre high roof-mounted wind turbines and the result is London’s largest building-integrated renewable energy array.
Value has also been added to the hard-to-treat towers through the creation of 12 super-insulated, low-carbon penthouses and the conversion of under-used ground-level storage areas into office space for rent to local charitable organisations.
