Internal Bifold FAQ's
What are internal bifold doors?
Internal bifold doors come in two variation.
- Internal Bifold Door - consist of 2 or up to a maximum of 6 doors depending on the width of your opening. The doors are linked with specialist hardware which allows them to slide and fold together like a concertina, hence they are sometimes called folding doors or concertina doors.
- Internal Fold Flat Bifold Doors - have between 2 or a maximum of 4 doors depending on the width of your opening. Again these are linked together with specialist hardware but unlike bifold doors that concertina together, Fold flat doors can rotate 180 degrees around against a wall leaving the opening completely free.

How to paint and finish internal bifold doors
- Locate in a clean and dry room
- Remove any dust from the surface areas using a micro-fibre or tack cloth
- Ensure the surface area is smooth and clean
- Apply a low tack masking tape around the edges of the glass if you have chosen glazed panels
- Lay the door(s) / frame flat on a raised surface
- Use a good quality clean brush, evenly apply 1 coat of chosen finish to all faces and edges of the door(s) and frame
- Allow the finish to fully dry
- Lightly rub down (denib) between coats
- Repeat the finishing process until you have applied 3 coats, ensuring the door(s) and frame are fully sealed and well protected
- Remove the masking tape from around the glass
What type of finish can I use?
Vufolds high quality unfinished internal bi fold doors can easily be painted, stained or varnished (Polyurethane).
We do not recommend using a wax or oil as this can cause various issues with the wood and will invalidate your warranty.
Once you have decided what type of finish you prefer you then need to consider the durability and sheen level of the finish.
The most popular choices are:
- Gloss (semi/full) - Is a very durable finish, it also reflects the light when dry resulting in a mid to high sheen.
- Matt - If you're looking for something more natural, these finishes deliver a smooth subtle look and show little to no sheen when dry as they absorb the light.
- Satin - Has some of the durability of gloss combined with low to mid sheen levels of matt, it's a great all-rounder.
Vufold recommends the use of Dulux, Sadolin and Sikkens products for our range of Oak veneer internal bi fold doors.
Natural or synthetic paintbrush?
Using the correct type of paint brush for the product you are using is essential.
Synthetic - paint brushes do not absorb much water and have finer tips which help give a smoother finish making them the best option when using water based products.
Natural – paint brushes are the superior option when using oil based products, the bristles absorb the product resulting in faster finishing.
How to measure up for internal bi fold doors
Before ordering an Internal bi fold door, you will need to measure the opening accurately. This can be done by following these four easy steps:
- Measure the width in the three separate places (top, middle, bottom).
- Measure the height from the top to bottom at three different points (right, centre, left).
- Subtract 5 - 10mm from the smallest measurements.
- Check the aperture is square by measuring the diagonals from corner to corner.
*Subtraction 5 - 10mm from the smallest measurements will allow you to ensure the frame can be installed perfectly square and level even if the aperture is slightly out of square.
How to fit an internal bifold door
The installation of a ready-to-assemble internal bi fold door is a fairly simple process, any knowledgeable DIYer can install their own internal bifolding doors.
While each range and size of bi folds has its own set of specific instructions, the basic installation steps are very similar:
-
Frame Assembly
The bifold door tracks are pre fitted to the head and sill and fixing holes are piloted in the respective frame parts. Lay out all 4 pieces on the floor or work horses in the correct locations, using the supplied screws (usually 12) assemble the frame into a square - ensure everything lines up nicely before final tightening.
-
Frame Installation into the opening
It is vitally important that you install the frame square and level in the opening this will ensure that your doors operate smoothly and correctly. It's worth spending a bit of extra time to ensure they are spot on. Use packers and the supplied drill bits and direct frame fixings to attach the frame into the opening. Ensure you use all the recommended fixing points which can be found in the specific product instructions.
-
Attach the Internal bifold door hardware to the frame and doors
Your instruction manual will specify the specific location of the bifold door hardware on the frame and also the doors. The location of these parts will be dependent on the number of doors and also which opening direction you have chosen for the doors
Items that will need fitting are:
- Dropbolts
- Top and bottom pivots
- Half offset hinges
- Intermediate carrier, guide and straight hinge.
- Seals
- Tubular mortice latch, striker plate and door handle
All hardware installation locations are fully pre machined, they are also pre-drilled or clearly indicated so that installation is easy and straightforward.
-
Install the door into the frame
Now that all the hardware is in place the first door can be attached to the frame then subsequent doors added until all the doors are secured in the frame. Again follow your specific product instructions to attach the door in the correct order
-
Final Adjustment
Once the doors are in the frame they may need a final adjustment to ensure they are working smoothly as intended. Vufold has designed their doors to ensure any adjustments are as easy as possible. Unlike standard bifold doors, Vufold RTA doors feature easy to adjust internal bi fold door hardware which requires very basic tools.
To adjust the doors to the left or right:
- Ensure the doors fully open
- Locate the top and bottom pivot hinge adjustment screws (see instructions)
- Use a screwdriver to adjust until satisfied
To adjust the height:
- Depending on the range you may need to adjust the bottom pivot with a screwdriver and spanner (provided) or the top pivot and intermediate carrier using an allen key (provided). Turn clockwise to raise the door height and anti-clockwise to reduce.
Go to our internal door installation advice section for further details.

Whats the difference between our internal bi-fold ranges?
Vufold offer two different styles of Internal Bi-fold door.
Finesse and Edge - Bifold Door
These are a standard style internal bi-fold door, you get a single traffic door that can be opened on its own. When you open all the doors they generally all slide and fold to one end with the doors protruding at 90 degrees to the track.
Inspire - Foldflat Bifold Door
With the Inspire range you still get a traffic door that can be opened independently of the others but when the doors open fully they can be folded back 180 degrees against the wall watch are short video below to see how they work.
What handles are available for Internal doors?
There generally four types of door handles which suit internal bifolds:
- Lever handles
- Flush handles
- Door Knobs
- Pull handle
Why not read our internal bifold handles guide which makes your selecting decision much easier and gives a helping hand on where to position them.
Why choose timber for internal doors?
Timber is the most common material for internal doors and provides great value, style and quality. uPVC often looks cheap in homes and aluminium is generally best suited for external bifolds. Read our timber vs uPVC vs aluminium comparison for internal doors for more details.
What’s the difference between primed plus and unfinished oak?
A primed plus door comes with a 2 step, high build finish. Providing a much better coverage than usual priming processes. The high build layers means some customers may not wish to add any additional layers of finish. Saving time and costs on site. Whereas unfinished doors come without any finish and will require you to finish them yourself, offering great customisation.
How do you maintain internal bifold doors?
They are generally very low maintenance but the following below steps can keep the door in perfect working order.
- The finish on the doors should be checked every 2-5 years and recoated if necessary. The coating may require more regualr attention if installed in a moisture rich enviroment (kitchen) or directly next to a heat source (radiator or log burner). The high moisture and/or varying temps can all contribute to the finish breaking down more quickly.
- Hardware, hinges, handles and tracks - All parts will benefit from a bi-annual wipedown with a damp microfibre cloth just to remove an build-up of surface contamination.
- A small amount of silicone lubricating spray can be used on hinges, bearings and slidebolts annually - this reduces wear and also improves the smoothness of operation.
