‘Intelligent-timber’ composite door

Sliders UK has launched its new PAS24 and Part Q approved ‘intelligent timber’ Ultimate Composite Door, which is manufactured using the new Capstone leaf featuring 15mm-thick LVL timber inserts.

Encased inside a foam core and durable GRP skin, these provide additional core strength without impacting on thermal efficiency.

This combination means that it not only achieves U-values of as low as 1.0W/m2K, but has been independently tested to PAS24:2016 – including cut-through testing.

Security is further enhanced through Capstone’s patented three-stage glazing cassette system, which supports easy replacement of glass but maximises security.

Steve Mines, sales director at Sliders UK, said: “Security is always a major driver in entrance door retail and this is among the most secure doors on the market.

“The major positive for the trade is that the way timber is used in the door not only makes it more resistant to attack – so that it’s Part Q approved – but encased in foam and GRP, there’s no chance of water ingress or warping. It also delivers great thermal performance.”

This combination of timber inserts and thermally insulating foam also reduces bowing, which means that the Ultimate Composite Door is supplied by Sliders UK with just a 3mm bowing tolerance.

“Bowing can cause a stack of problems and call-outs impacting on weather sealing and locking,” Steve said. “With a 3mm tolerance, compared to the 5mm and 7mm tolerances of competitor systems, we’re underwriting through-life performance.”

Door furniture and hardware is Trojan, while standard hinges and locks are manufactured by Ingenious, with heritage and auto-locking options from Winkhaus. Door cylinders are six-pin anti-drill and pick as standard with the Ukas-accredited 3-Star BSI TS007 tested Ingenious cylinder available as an upgrade option.

Glass options include a choice of double or triple-glazed options, achieving U-values as low as 1.0W/m2K including laminated and toughened options.
