German steel cable specialist Carl Stahl has added several products to its I-SYS range of architectural hardware. These include the F50, a threaded stud attached to a stainless steel cable. This is designed to make attaching steel cable to load-bearing members easier. A ball-and-socket joint has been launched to simplify constructing stair balustrades; the joint accommodates any stair pitch up to 60º without the need for purpose-made cable terminals. Carl Stahl has also introduced its "green facade" system, a stainless steel cable trellis structure for climbing plants, available as a kit.
Glass-reinforced, plastic door specialist Therma-Tru has introduced a secure doorset called Secur-Tru for public sector and housing association projects. The company says the doors conform to the requirements of PAS 23 and 24 exterior door specifications, a police and local authority standard for burglary resistance, and has an impact resistance 10 times greater than steel, and five times that of wood. The doors incorporate a carbon steel mesh within the polyurethane core; the outer parts of the door have extra-thick sections, and the frame features steel reinforcement.
A colour wireless CCTV camera has been developed by home security specialist Micromark. The company says the system is easy to install as there are no wires, and the user can view the image on their television set. The camera's transmission has a range of 100 m if the television is in sight of the camera, or 20 m if the signal has to pass through two brick walls.
Nail-free building adhesive
Laybond has added a nail-free fixing to its Gripfill range of building adhesives. It is a solvent-free, gap-filling adhesive available as a 250 ml squeezable tube and a 310 ml cartridge. The company says it has excellent initial grab, forming a high strength bond between materials including wood, plasterboard, ceramic, most plastics and brick. Its gap-filling properties also mean uneven surfaces can be bonded.
One-piece shower for fewer leaks
Douglas James has launched what it claims is a leak-free, one-piece shower pod. The shower unit is cast from a polymer-bound stone material and comes complete with glass doors and screens. Several models are available, including the Vision Plus, a 1100 mm wide pod featuring a large sliding door and soap shelf, and the Vision Quad that has a curved glass screen and sliding door. The company says the showers are suitable for the domestic, leisure and hotel markets.
Opening rooflight specialist Velux has launched a range of blinds to go with its products. More than 160 colours are available in pleated, venetian, roller and blackout versions. The blackout, or siesta, blind is also available as a battery-powered motorised version, operated by remote control.
Fire protection for downlighters
A protection cover called Firecap to prevent fire from breaching fire-rated ceilings through downlighters has been launched by Aico. The company says unless fire-rated downlighters are fitted, the integrity of a ceiling is compromised. Aico says the Firecap is easily fitted over a downlighter without the need for screws, drilling or sealants. Holes for cables and ventilation slots to enable heat to escape from the lamp are provided. In the event of a fire, the intumescent product swells up and blocks the holes. It is claimed to offer 60 minutes of fire resistance.
Zumtobel Staff Lighting has collaborated with Sottsass Associati to develop a luminaire called Light Fields. It features a "micro-pyramidal optic" that is claimed to eliminate direct lamp glare without any loss of luminance. The company says this means desks can be positioned anywhere in a room without glare affecting computer screens. The luminaire is available in surface-mounted, recessed and pendant versions.

Valve to stop pipes banging
Danfoss Randall has developed a new type of thermostatic radiator valve called Revolver that is designed to eliminate the problem of "water hammer" in bi-directional valves. Bi-directional valves allow plumbers to fit TRVs without having to determine the direction water flows through the valve. The company says in a small number of cases "water hammer", or loud banging in the central heating pipes, is a problem with this type of valve. The Revolver is fitted with a plastic collar within the valve body that, when turned, reverses the flow of water within the valve, which is said to eliminate the problem.
