Product innovation

Timber specialist Paragon Joinery has launched a product that could give the PVCu window industry sleepless nights. It combines the maintenance-free virtues of PVCu with the green credentials of timber. Called Virtuoso, it is a laminated timber section faced with a vinyl foil. Paragon says it is undergoing accelerated weather testing in Germany and has lasted for 75 years without water ingress.

Laminated timber has other advantages over PVCu and ordinary timber, in that it can take up to seven times as much stress as ordinary timber, and is up to 40% more dimensionally stable than plain wood. These qualities make it ideal for specialist applications: for instance, Paragon products were used for bombproof windows at the Scottish parliament (above). This was the first timber bombproof window: up until now such windows were made from metal. At Holyrood, European oak sections were laminated together to create a window that can resist a force of up to 13.9 kN. The company has taken this experience and developed a bulletproof window, made from layers of beech ply interlaced with resin and placed under extreme pressure.

But PVCu makers will be watching the more everyday Virtuoso. The threat is that Paragon will make window sections to supply to fabricators in the same way as PVCu suppliers do. Paragon says that fabricators can make windows on the same equipment as PVCu.

Bluetooth-controlled sliding doors

Kaba Door Systems has launched a system called SLX for operating automatic sliding doors. Kaba says the motor, scanner and controls are contained within one small unit positioned at the top of the door. The product is aimed at design-led installations and is suitable for operating conventional and telescopic door wings of all sizes and weights. The SLX can be operated using Bluetooth from up to a distance of 10 m. This means that Bluetooth-enabled mobile phones, personal digital assistants or Kaba key fobs can all be used to control the system, as well as the company’s BEDiX portable control unit or its C-BEDiX wall-mounted unit. This provides access by means of a password.

Fire safety doors

Fireco has brought out a version of its Dorgard door hold device that is suitable for noisy environments. The system works by placing a transmitter with a 30 m range of a fire bell or sounder. When this goes off, the unit sends a signal to the receiver unit attached to the fire door that is being held open by the Dorgard device. This releases the door so that it closes automatically. The company said the transmitter could operate any number of doors.
