BI-FOLDING DOORS
‘MULTI FOLDING DOOR COMBINATIONS’
Bi-folding doors
(multi-folding
)
are becoming very popular indeed and you will see them in most
glossy magazines. There is however a word of caution:-
Folding doors are somewhat complex structures to design, manufacture and ensure
that they operate efficiently for the foreseeable future. There are a
great deal of
inferior products on offer.
You also need to consider how often the large opening
provided by these doors will be effectively used in the U.K. climate. A standard pair of
French doors can provide a 1800 - 6ft opening at often half the price of folding door
combinations and it is only for a short period of the year. Balmy weather will enable
you to throw these wide open. If you are to fully enjoy the large openings created by
folding doors, then I would suggest an ideal opening width of 3 metres – 10ft 0ins for a
good balance of door frames in relation to the opening this will achieve.
There is also the important consideration that any large opening needs to have the
property wall or
conservatory roof above structurally supported
and this will generally
involve
appropriately designed structural portal frames or lintols.
These can be an
expensive item over and above the cost of the doors themselves. Many people who
have bi-folding doors installed make the comment that
‘in the open position all of the
leaves do not magically disappear’
and whether opening into your home or outwards,
they collapse into what some may consider a bulky stack, which is often not
appreciated until the doors are fitted and in operation.
An odd number of doors are preferable. This provides a single door opening or two
doors to fold back as with French doors opportunity plus the large opening when all
the doors are folded back. When an even number is chosen, the panels will open into
these - ‘V’ and this creates difficulties with operating the system and for locking
arrangements.
We offer high specification Hardwood, Architectural Aluminium or PVCu designs.
We are pleased to offer a full design and advisory package for all sliding, folding and hinged
doors. Thereby, ensuring you ultimately choose the very best system for your home.
