You might think it presumptuous for us to say that doors need to be designed around the door hardware, but it is true. In 10 years, we’ve seen construction projects disrupted and delayed through a lack of attention to detail in this area. Don’t let your next project fall victim to ‘door and hardware isolation.’
If a door is designed without any consideration of the door hardware, it’s a bit like trying to buy shoes for a distant relative you have never met. You may know that he/she likes tan leather shoes and does not like tying laces but this information is useless unless you know the person’s shoe size.
It’s the same with door hardware. You need to consider which door hardware you are going to use simultaneously when designing your doors. A conversation with an expert door hardware supplier to discuss your design and compatibility with the hardware you wish to specify could save your project time and money.
A few basic door details which are essential to a door and hardware perfect fit:
There is no such thing as a ‘standard’ door height, which means specifying the correct door hardware is a meticulous and detailed process. Door height can affect many elements of the hardware, for example the higher the door, the heavier the door – this can mean more or higher spec hinges are required. Height also affects items like bolts and handles, traditional size handles can look lost on a big door. All these requirements can impact on the design process, if the door is designed without any consideration of the door hardware, you can lose time and money whilst delaying delivery.
A basic rule is:
This obviously depends on the thickness, width and material of the door.
The width of the door can have an impact on the number of hinges – an increase in width in turn creates a higher strain on the hinges, which can increase scale and costs of an architectural design project.
Thicker doors are becoming an increasingly popular trend in high-end luxury design projects, but what factors should specifiers consider when choosing hardware to avoid unnecessary delays?
The thickness of the door can impact on the chosen luxury hardware, the thicker the door generally reduces the choices. Some manufacturer’s items only suit up to a 50/55 mm door thickness. Thicker doors have an impact on the fixings of door handles, often the standard fixing that comes with handles are not long enough to cope with doors thicker than 50mm.
Standard key lengths can sometimes not be long enough when using traditional locks, if cylinder locks are being used the length of the cylinder needs to be carefully worked out, especially if for any reason the lock has had to be fitted off-centre then an offset cylinder will be required. If the standard strike plate isn’t long enough the strike bolt in the lock or latch will close against the door frame and damage it.
Door Stile Depths
The door stile depths can have an impact on lock choice and handles. If the stile depths are too narrow it can mean that it is not possible to fit an adequate lock into the space. This can especially be a problem if door knobs (as opposed to lever handles) are specified. All locks have a fixed backset which means that if a designer is trying to position the handles in the centre of the stile the stile depth will be governed by the lock backsets. The narrower the stile the harder it is to accommodate, also the more timber there is available the stronger the door.
Rebated Stile Details
The rebated stile details impact on lock choices. Rebating the leading edges of double doors is a very good way of ensuring privacy and that drafts and the elements are kept out. However if a door has a rebate detail it does mean that locks and latches will require a rebate conversion kit, and rebate details must be designed to work with rebate conversions kits (hardware item). Rebates are normally used on double external doors although they are also used on double internals and occasionally single doors.
It is vital that the door design and the door hardware are considered together to avoid any unduly costs, stress and changes later on in your interior design project. If you take into consideration your hardware and door design at the same time you’ll be sure to see a smooth and simplified project process.
