£200.52 inc VATSlimline internal bifold doors are specially designed to fit narrow door frames. Bifold doors are a good solution for wide entryways but if you only have a narrow, single leaf doorway, you can still enjoy the stylish look of folding doors with slimline bifolds. Slimline bifold doors often only include 2 panels that fold together when opened. In such a door, each panel would only take up half the width of a standard door when open, making slimline bifold doors a great choice for tight spaces.
PLEASE NOTE: For all Slimline Internal Bifold doors, the door leafs arrive shorter than the 1981mm shown, with the remaining space being accounted for in the track and running hardware.
Due to their neat size, slimline bi fold doors can be very versatile in their usage. Whereas larger bi folding doors may be best suited to large living areas, slimline bi fold doors can be used across the home. Some ways you may choose to use internal bi fold doors include:
Bi fold doors can be an effective choice for built-in wardrobes in bedrooms. They are a stylish and practical choice that can be seen as halfway between standard side-hinged doors and sliding doors. Their narrow leaf width suits openings too tight for a standard hinged or sliding wardrobe door.
Similarly to wardrobe doors, internal bi fold doors can be used for many different cupboards in the home. From playroom storage to home office organisation, bi fold doors can provide a neat and attractive frontage for your cupboards that need a narrow, space-saving front rather than a full-swing hinged door.
Slimline bi fold doors can be a good choice for a kitchen pantry. With their neat profile and smooth operation, they can offer a more compact option than a standard door. Bi-fold kitchen doors are ideal for allowing access to your full pantry without taking up space in the room when opened. Beyond pantries, slimline bifold doors are also fitted to kitchen cupboards, larder units and utility openings where a full-swing cupboard door won't clear the worktop or an island.
Wherever you might have a tight space within your home, slimline bi fold doors can be a good space-saving solution. Whether it’s for a box bedroom or an upstairs landing airing cupboard, the narrow width of slimline bi fold panels makes for a practical door.
In our range of slimline internal bifold doors, we have choices to suit many different homes and interiors. With a range of materials, designs and finishes, there is something to suit all requirements.
Our slimline bifold doors come in 3 different finishes: fully finished, primed or unfinished. If you want a ready to hang, factory finished door then our finished bifold doors are for you. Primed doors allow you the chance to paint your bifold doors in any colour you wish. With the priming done for you, these are also known as part-finished doors. Lastly, you can opt for unfinished bifold doors. These doors tend to be a little cheaper if the price is a concern, but it does mean you will have to do the finishing yourself. However, if you are looking for a particular stain, wax or other finish, this allows you full control over the final result.
Our range of bifold doors covers several different timbers and styles. We offer slimline internal bifold doors in classic oak and pine. We also have a wide range of white bifold doors for a bright and modern look.
Our slimline bifold doors come either glazed or unglazed. Glazed bifold doors have the benefit of increasing light flow between rooms which can help space feel brighter and bigger. If you are using your folding doors for a pantry or office space, glazed doors have the advantage of letting you see the contents of your cupboards. We offer a range of different styles of glass panel in our bifold doors, from the decorative to the minimal and modern.
We also provide unglazed doors which are simply solid panels, without any glass. If you want to create privacy or hide away storage space for an uncluttered feel, unglazed bifold doors are a good choice.
Frequently Asked Questions
Slimline bifold doors are made in the UK's standard imperial internal door widths, and each leaf can be trimmed by up to 6mm per side, so they fit openings too narrow for a standard hinged or sliding door.
Panels are supplied with 10–12mm lippings and can be trimmed up to 6mm from either side (not top or bottom) for a precise fit. A slimline bifold typically has 2 panels, so each one only needs to clear half the opening width when folded back, unlike a single hinged leaf. Door leaf height is set to suit a standard 1981mm opening once fitted; leaves arrive slightly shorter than this to allow for the hanging hardware.
Yes, these slimline bifold doors are designed for small and narrow spaces where a standard hinged door would need too much swing clearance. The panels fold flat rather than swinging into the room, which suits box rooms, small en-suites, airing cupboards and narrow landings. Unglazed panels give full privacy in a small room; glazed panels keep a small space feeling lighter and more open. Oak, pine or white finishes keep a small-space door visually consistent with the rest of the room's woodwork.
A single bifold door is a 2-panel slimline bifold fitted into one standard door opening, as opposed to room-dividing bifolds that use 4 or more panels across a wide opening. This slimline range is built for single door-width openings: typically 2 panels folding together to one side. For wider openings needing more panels, the Roomfold Standard, Grande and Deluxe ranges are the multi-panel equivalent. The same finish, material and glazing choices apply as the rest of the slimline range: oak, pine or white; fully finished, primed or unfinished; glazed or solid.
