Bifolding doors are becoming a very popular upgrade for new conservatories as they provide much wider
unobstructed door openings than traditional French double doors or sliding patio doors. When fully open
these folding sliding doors allow you to seamlessly merge your garden with your conservatory and bring
the outside inside.
If you are considering adding a bifold door to your new conservatory here are a few essential points that
should be considered.
When selecting the size of folding sliding door for your new conservatory it is important to remember that
adequate structural support for the roof must be provided to prevent any possibility of deflection in the
conservatory roof when the doors are fully open. Most conservatory roof systems now provide optional
reinforced structural components that have been designed specifically for use where bifolding doors are
to be fitted and provide a stronger reinforced eaves beam to support the roof. Bifold 13
However, you will be limited to a maximum width of door aperture based on the door's position together
with the style of conservatory and it's projection which allow weight and snow loadings to be calculated.
Typically, a folding door width of up to 3.5 metres may be possible using these reinforced eaves beams.
If you require a wider aperture or are considering multiple sets of bifolding doors for your new
conservatory steel beams or a fully engineered steel portal frame may be required to provide support for
the conservatory roof. This will require a structural engineer to calculate the loadings and design a
framework that may not always complement the design of your conservatory and will substantially
increase your costs. Bifold 13 LTD
Once you have determined the width of the door aperture you can select a folding door style that suits
your individual requirements. Most styles feature a hinged traffic door that provides single door access to
the garden which is useful during the colder months of the year when you don't want to open the
complete door. Traffic doors also provide external handles and key locking allowing conventional door

There are also other bifolding door styles that do not include traffic doors which also means that all
locking handles are on the inside only without any external key or handle access on the outside which
can be particularly important where security is a concern.
Height of thresholds is usually a very important factor for new conservatories and most bifolding door
systems will provide a choice of flush or low thresholds to eliminate trip hazards although some low
threshold options may not be as weather-proof as purpose designed flush thresholds.
Folding sliding doors are available in a choice of materials and finishes to complement your new
conservatory including powder coated aluminum and PVCu doors that can be sprayed to a specific colour
or supplied in a wide range of coloured wood grain foil finishes.
All glazing options currently available for conservatories can be specified for the bifolding door including
self cleaning solar control glass designed to help reflect direct heat from the sun helping you to control the
conservatory climate and protect your furniture. Bifold 13 LTD
Adding a bifolding door to your new conservatory will open-up your new living space with the outside and
create an extended living space that can be instantly merged with the outside.
