INSTALLATION NEWS A classical solution
Saint-Gobain PAM UK has been chosen to supply a major listed building with its range of Classical rainwater and gutter systems.
Ubbeston Hall is a grade 2 listed early 18th century building, located in Suffolk. It recently underwent a major renovation which involved replacing the existing cast iron rainwater systems after a lifetime of service with new 150mmx100mm moulded cast iron gutters with 125mmx100mm rectangular cast iron downpipes supplied in
the Classical Plus high quality pre-painted finish.
Cast iron was specified for both its long- term performance characteristics and also its unique aesthetic qualities which make it first choice for external rainwater systems on prestige and listed buildings. Supplied ready to install, in a quality semi- gloss, black polymer powder alloy (Plascoat PPA 571 ES) finish, the Classical Plus range offers excellent performance, and minimal maintenance.
Dimplex
ensures a warm reception
There’s a warm reception for visitors to the prestigious Kingsway Hall Hotel in London’s Covent Garden, thanks to the installation of a Dimplex ARC architectural air curtain that helps prevent draughts from the frequently opening doors. With a history that dates back nearly 100 years as a sought after orchestral recording venue for stars including famous tenor Luciano Pavarotti, the recently refurbished 170 bedroom hotel in the heart of London is now popular with all types of leisure and business guests. As a result its large entrance doorway, with automatic sliding doors, is in constant use.
The two-metre high doors open into the main reception and adjacent busy bar area, so draughts, particularly on cold days, were recognised as a particular problem requiring a specialist solution. General Manager, Laszlo Nyari says: “These doors are automatic and large, with lots of guests coming and going all the time which means that our lobby and bar area gets cold very quickly. We also had to think quite carefully about the aesthetics and general guest comfort because positive first impressions are vitally important in our business.”
Mr Nyari consulted John Kindell from the hotel’s electrical contractors, Sussex-based JWK Electrical, as part of his research to find the ideal product which needed to be high quality from a trusted brand name as well as looking as stylish as possible.
Specific requirements
“A stainless steel Dimplex ARC architectural air curtain was selected and installed over the doorway, to meet the exacting specifications,” added Mr Nyari. “The ARC is modern looking and quite slimline so it looks good. We keep it on permanently at busy times because heat can escape very fast through the doors and we need to ensure guests are kept warm and comfortable at all times.”
The Dimplex ARC air curtains are capable of being linked with other units to operate over multiple doors and have fully integrated links to BMS/BEMS system for fully integrated control. There are horizontal and vertical models, all of which can be colour finished to customer requests.

Advanced smoke ventilation from SE Controls protects Nottingham students
A £55 million student accommodation development in Nottingham is using integrated smoke and heat exhaust ventilation systems from SE Controls to provide smoke free escape routes for around 1000 students living in the new purpose designed apartments at Chettles Yard. To meet the fire safety and smoke ventilation needs in three of the new buildings at the Chettles Yard development, SE Controls developed specific smoke and heat ventilation solutions for each accommodation block based around its versatile SHEVTEC®
system.
As the maximum escape travel distance in two of the apartment buildings was within the 7.5 metre limit covered by Approved Document B of the Building Regulations, the SHEVTEC Natural Corridor Ventilation System was installed. However, the six storey F Building had a travel distance of 12.0 metres so SE Controls created a dedicated fire engineered solution around its LABC approved SHEVTEC Extended Travel Distance System.
In the event of a fire, the main exit route is through a single protected stairwell, so the SE Controls solution had to provide high integrity smoke and heat ventilation that not only allowed occupants to travel the increased distance to safety, but must also perform at least as well as the code compliant systems installed in the other two accommodation blocks.
The extended travel system used in Building F was originally developed by SE Controls using advanced computational fluid dynamics (CFD) to create an off the shelf, fully compliant and CE marked solution that can not only assist escape but also simplify the building’s design by removing the need for additional escape stairs.
In addition, the size of the smoke shafts used can be reduced to less than half of the 1.5m2 required under a typical natural ventilation system. When combined with the requirement for only one escape stair, this allowed the developers to incorporate more apartments within the building’s envelope.
The SHEVTEC system uses a dual smoke shaft and fan ventilated solution linked by smoke sensors through SE Controls’ powerful OSLoop®
control system, which when triggered determines
which shaft is closest to the fire and automatically opens the smoke shaft doors on each floor to extract smoke away from escape routes, corridors and stairs. Once actuated, OSLoop continues to monitor the entire system throughout the incident to ensure the system maintains its performance in accordance with the imminent EN12101 part 9 standard. SE Controls provided a full turnkey solution to the Chettles Yard development, involving project management, the supply and installation of the SHEVTEC system and liaison with all the appropriated authorities and inspectors, as well as full testing and rigorous commissioning procedures to verify the system’s performance, operation and compliance with the design brief.
