Kalwall Translucent Cladding - Crouch End Picturehouse

The Crouch End Picturehouse in North London is an interesting example of how Kalwall® can be used to convert an ugly 1950’s concrete building into a state-of-the-art space suitable for the 21st Century.

•   This project by Panter Hudspith Architects forms part of a wider initiative within the London suburb of Haringey aiming to re-establish the area as one of London’s cultural and arts centres. The result is a remarkable transformation of a building, originally a factory then an office, into a £4.5 million cinema complete with café, bar, restaurant and community rooms.

•   The unique style of this four-screen cinema has attracted much interest, not only because of the dramatic transformation but also because of its new external elevation.

•   The use of Kalwall, coupled with other sustainable measures including solar panels and a green wall, means the picturehouse has achieved a BREEAM rating of Very Good. 

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.
