46 SMOKE & FIRE PROTECTION; STRUCTURAL ELEMENTS Door closer’s fire credentials enhanced
Samuel Heath’s commitment to ensuring that its Powermatic controlled, concealed door closers provide the ultimate assurance in quality and performance has been further underlined with the successful completion of additional full- sized fire testing on both timber and steel fire doors at renowned testing laboratory, Exova Warrington Fire. 30-minute testing in accordance with BS EN 1634-1 was undertaken on a timber fire door constructed with a Halspan core to replace Powermatic’s current small-scale indicative testing for the BS476 assessment. The door set easily achieved the 30-minute test requirements, continuing until final failure occurred at 42 minutes. Significantly, where most timber door fire tests fail due to failure of the hinge/timber joint, which causes the door to drop and intumescent seal to break at the top of the door, Powermatic was actually shown to hold the door in place after the hinge/timber joint failure. This is attributed to the design, strength and location of Powermatic, which fits in a similar position to hinges, between the door and door frame. Most notably though, and in common with other fire tests including Powermatic, there was no evidence of any significant heat transfer in the vicinity where the closer was installed. The uninsulated steel door passed the four-hour test comfortably.

www.concealeddoorclosers.com The world’s most advanced collated screw system just got even better!
Simpson Strong-Tie’s Quik Drive auto-feed system is a significantly faster way to install screws. With a multitude of modular fittings and screws for a huge range of purposes, there is a Quik Drive kit to suit just about every applica- tion – from drywall installation to mezzanine floor construction. A perfect alternative to traditional nailing and screwing. The ergonomic design allows the installation of screws into walls, floors and ceilings without the need for bending, stretching or crouching. Which means not only can the system operate for several hours at a time – so can you. The Quik Drive system fits onto all leading dry wall drivers with just a click. The patented screw strips are designed to avoid jamming, and unlike many collated screw strips, a partially used one can be saved for reuse later – so it’s cost effective too. Sales Manager, Phil Chambers, explains: “The Quik Drive system has been on my radar for some time, it’s not just fast, it’s really (really) simple to use. It’s great to see the lights go on in peoples mind when they give it a try.” In addition to Phil conducting Quik Drive demonstrations throughout the UK, an all-new catalogue now features additional Quik Drive equipment and collated screws, including some tools that can be used to install construction connectors.
