Challoners Gardens, a development of 45 bungalows owned and operated by Isos Housing, was so badly affected by floods when the nearby River Wansbeck burst its banks in 2008 that residents had to be evacuated. To prevent this happening again, Isos and its consultants, Faithful & Gould, specified that DuoGuard doors should be fitted front and back on all the dwellings.

“We needed a door that not only reduce the possibility of flood water causing the costly damage we suffered in 2008; but one that our residents could operate and which also looked good,” says Andy Kennedy, support services Manager at Isos Housing.

DuoGuard’s unique double rebate and 12 locking points combine to provide unrivalled enhanced protection against flooding – being up to 200 times more flood resistant than a standard single rebate composite door – and break in compared to a standard single rebate door. Manufactured using CFC-free polyurethane foam for the inner core, the door’s construction is timber throughout and, thanks to its double rebate and 68mm thickness, improves both heat and sound insulation.

The door also provides class-leading security. As well as the 12 locking points securing it to the frame, it also has high security hinges and a six pin anti-drill/ anti-bump euro cylinder. It is fitted with an extended lever (DDA) handle, so is ideal for supported housing with either disabled or elderly residents.

In this case, there were concerns about whether the Challoners Gardens residents would be able to operate the lever that engages the locking points, so an open day was held at a vacant dwelling fitted with the doors so residents could try them out and they could be adjusted accordingly.

DuoGuard Doors, like all Bowater by Birtley, are designed on a ‘Doors for Life’ ethos so they can be adjusted according to a resident’s changing needs.
