Kalwall Translucent Cladding - BH2 Bournemouth

BH2 is a £30m development creating a newly-constructed leisure complex in Bournemouth

•  Originally a two acre NCP car park and bus station, main contractors Vinci has built a new 10 screen Odeon Multiplex cinema, café, casino, restaurant and retail complex.

•  Structura was appointed to design and supply Kalwall translucent facades to enclose the external fire escape routes around the perimeter of the building.

•  Structura installed multiple Kalwall translucent elevations, totalling over 1000m2, providing natural daylight to internal areas by day and a soft ethereal glow which brings the area to life at night.

The Solution

Panter Hudspith Architects replaced the original curtain wall and specified Kalwall® for the front elevation. Unusually, this unique translucent cladding is fitted with a tight 150mm wide grid, known as Verti-Kal™, which not only serves to emphasise height but is the first of its type in the UK. On this scheme the Kalwall panels also insulate to 0.78 w/m2 making the building eye-catching and sustainable.

Unlike conventional glazing, Kalwall eliminates shadows and glare and the stark contrasts of light and shade. The system also enhances simplicity by eliminating the need for blinds, curtains or solar control. Even on cloudy days, the interior is bathed with natural daylight, which means less artificial lighting and, because Kalwall is highly insulating, energy costs are reduced.

Kalwall is increasingly being used in the UK for new buildings and also for the refurbishment of cladding or rooflights on aged buildings. One of the main attractions of specifying Kalwall is its unique effect on both the interior and exterior. Although translucent, it offers the big advantage of privacy while the elevations appear crisp and simple. When illuminated at night they emit an inviting ethereal glow.

The Comments

Architect James Jeremiah comments, “This is the first time we’ve specified Kalwall and it fulfils our vision of retaining the modernist characteristics of the building. One of our original concepts for the building was of a zoetrope (one of the earliest forms of moving image) and there’s a strong history of using transparency in films with people moving behind the shadows. We felt the Kalwall system was a very good fit for what we wanted to achieve”.

Amanda Birch, Technical Editor Building Design writes, “To appreciate fully the building’s transformation, it is best viewed from the street. The concrete structure has been retained along with its striking line of concrete columns, which are now a strong feature of the front elevation. The original coloured insulated glass panelled system has been replaced at first and second floor levels with Kalwall’s 75mm thick insulated cladding system creating a dynamic façade that is particularly effective at night.
