F A Q (Frequently Asked Questions)

Please click on the question that you would like to view.

  Are your doors really suitable to DIY installation?
Many of our doors are fitted by homeowners or their builders.  If you are a DIY enthusiast you should be able to install the door with the help of a willing volunteer.

  Are your doors supplied in kit form or fully assembled?
Our bifolding doors are fully assembled in the factory although due to transport restrictions some larger doors are supplied with the outerframe in kit form for assembly on site.  All doors can be supplied this way on request if you have limited site access.

  Can you supply matching aluminium windows and doors?
We can supply windows and doors designed to match and connect to bifold doors.

  Do you install?
Depending on your location we may be able to introduce you to a professional installer who will survey and install your door for you.  Payment for this service is made directly to the installer.

  Do your Bifolding doors comply with building regulations?

Yes, they are fully compliant with document L of the building regulations.

  I want a threshold that is flush with my floor – is this possible?
There are 2 threshold options.  A low threshold(which can be sunk into the floor)for internal use and a weathered threshold for external applications.  A pdf download with dimensioned drawings of both types can be downloaded.

  If I don’t want a traffic door can the door be opened from the outside?

Doors supplied without a traffic door can only be opened from the inside by operating the high security shoot bolt locking system by turning the handle(s) fitted to the meeting stiles.

  What are RAL colours?
RAL colours are the industry standard colours for painting aluminium.  Your door can be painted to any RAL colour code and a chart is available for download from the site.

  What are the style options?
Individual sash widths are 600mm minimum and 1000mm maximum.  Overall height is maximum 2500mm.

  What are trickle ventilators and do I need them?
If your bifold door is being installed into a new external opening you will probably require trickle vents fitted unless you have windows in the same room that already have trickle vents fitted.  They are designed to allow through ventilation without the need to open a window or door. Building regulations require 8000mm2 of trickle ventilation into a habitable room.

  What is 'U' value
U value is the measurement of heat transferred through a product and is commonly used to measure heat loss.  The lower the U value the lower the heat loss.

  What is a traffic door?

Traffic doors are available on some door styles and provide a door leaf that can be opened as a normal hinged door for ease of access.  They are supplied fitted with a high security hook bolt locking system, operated by lever/lever handles and a profile lock cylinder enabling access from outside.

  What is the difference between upvc and aluminium folding doors?

Aluminium Bifold doors have been proven for many years in Europe and provide slim sightlines.  They are available in widths up to 6 metres and can be supplied to open inwards or outwards.  uPVC bifolding doors are a recent introduction and their bulkier profiles restrict the sizes available with most systems unable to provide an open outwards solution.

  What is the maximum height of your folding doors
Doors are available up to a maximum of 2.5 metres in height.  Fixed glazed top lights can be supplied where the aperture is taller.

  What is your guarantee?
10 years on sealed units and paint finish with 1 year on locks and fittings.

  What maintainence is required?
Our bifold doors are designed to be virtually maintenance free. Just the occassional wipe with a damp cloth and lubrication of hinges and lock is all that is required.

  What type of double glazing do you supply?

Our Bifold doors are supplied with 28mm toughened Tripleshield argon filled Low E double glazed units as standard.  We can also supply any other requirement such as self cleaning glass, solar control glass or laminated glass.  Decorative glass such as lead or Georgian bar designs can also be provided.
