Isolate fire-rated composite doorset from New World Developments

New World has launched Isolate, a 30-minute fire-rated composite doorset for use in multi-resident housing with Secure by Design certification. With a Kerto core encased in 2mm GRP skins, similar to Apeer and Monno, it has the same distinctive grain definition and moulding. Set in a hardwood frame, Isolate’s 44mm thick door slab incorporates a single glazed cassette with fire resistant clear glass. There are eight solid and four glazed door styles available in white, blue, red, and green.

Designed specifically for local authorities multi-resident housing or sheltered accommodation, where elderly or vulnerable people live independently, New World’s Isolate fire door will help to provide an enhanced protective environment. With a 10% moisture content, Isolate’s 39.5mm core is a strong laminate, Kerto. Carrying a PEFC [environmental sustainability] endorsement, it has a slow burn rate and ideal for New World’s Isolate where the aim was to produce a robust, fire resistant door slab.

As 50 per cent of heat is transmitted through glass by radiation, smoke, gases and flames are also kept at bay by the 7.2mm Pyroglass cassette. Together with the intumescent seal, these are secured in place with hard wood beading.

Fire doorsets are subject to severe tests and the whole doorset must pass, including the door slab, frame and hardware. Isolate has a 70mm mahogany hardwood frame (tested to BS EN 942) to ensure that the integrity of the structure remains intact for the minimum 30 minutes and beyond. As well as Isolate’s fully-tested closers fitted as standard, New World has used a Millenco Mantis brass or stainless steel locking system, including a 20mm brass faceplate, three hooks, two deadbolts and three flush-fit flag hinges.
