External walls are of a durable one-piece construction with high-performance, low-maintenance plastisol-coated galvanised steel cladding to offer protection against fire, extreme weather and accidental damage. Internally, the walls are of polyester-coated galvanised steel, providing an impact resistant, wipe-clean finish.
The floor has a rigid galvanised steel frame and an aluminium-zinc coated steel sheet underdrawing, which offers a sturdy and robust feel. The floor design also prevents infestation as the thermal insulation material is laid on top of the underdrawing. The suspended floor is completely integrated into the structure of the building. The design enables the building to be sited close to the ground for one-step easy access. The floor can be finished with a variety of floor coverings including hard-wearing vinyl, carpeting or chequerplate*, depending on the application of the building.
Outstanding insulation is provided by the construction of the roof. The roof deck is of one-piece construction and is impact resistant. It is covered with solar-reflective, profiled plastisol-coated galvanised steel to reduce heat gain. Internally, the ceiling is designed to prevent condensation problems. It is covered with the same polyester steel as the walls for a low-maintenance finish.
Doors and windows
Steel-faced doors have an insulating core that minimises heat loss. The anodised aluminium frame also incorporates draughtproof weather seals. Protection against theft and vandalism is given by a cylinder mortice lock, which has escape override on the inside. The fixed, top hung or sliding windows have distinctive radius cornered aluminium frames with a polyester paint finish. Tinted glazing – toughened on top hung windows – reduces solar glare and a thermal break prevents condensation problems.
Pacemaker buildings can be linked to form larger complexes or stacked to form two- or three-storey buildings. A variety of room layouts can be achieved by the installation of partition walls, with a matching polyester steel finish.
Pacemaker buildings are quickly and easily sited. They may need pad foundations, depending on site conditions, the total weight of the building and the imposed loads - advice on foundation loads and positions will be given by Portakabin staff.
Peace of mind is guaranteed by the high levels of all-round performance achieved by the Pacemaker building series. It has been independently assessed by the British Board of Agrément (BBA) and awarded a BBA certificate confirming that it meets relevant requirements of The Building Regulations (England and Wales), The Building Standards (Scotland) Regulations and other permanent building standards and codes of practice. In addition, Portakabin also offers a 5-year product and a 20-year structural warranty on all new Pacemaker buildings*. The Pacemaker building series has been designed and manufactured in the UK under a Quality Management System meeting the requirements of ISO 9001.

Walls, doors and roof are insulated with environmentally friendly CFC-free Envirofoam, a rigid polymer insulation material that is lightweight and yet enhances long-life structural strength and ensures an energy-efficient building.

Fire-engineered construction ensures safe fire performance. Non-combustible materials are used for all external cladding and internal lining of walls and ceilings, minimising the potential fire load. Walls, ceilings and floor underdrawing have Class O surfaces, roof decks have an FAA rating. The floor has half-hour fire resistance in multi-storey mode.
A variety of heating, ventilation and air-conditioning systems can be provided to meet comfort requirements.
Transport and handling
Pacemaker buildings are transported by lorry and may be craned into position. All buildings have as standard provision for lifting at high level but can be provided with low level lifting as an option. Four leg chain slings must be used for high level lifting and four leg polyester slings must be used for the optional low level lifting. Low level lifting supports The Work at Height Regulations 2005 to avoid the increased safety risks associated with working at height and on roofs. Alternatively, the telescopic Lodastrut leg system enables single storey buildings to be positioned by one person using the optional jack. Portakabin staff will provide full advice on the procedure.
