Benefits of wooden internal bifolds

1. Stylish

Wooden bifold doors utilise modern technological advancements for a contemporary stylish look and feel. They are considered one of the better-looking materials compared to synthetics such as uPVC.

2. Durable, long-lasting and high-quality

Vufold creates high-quality wooden internal bifolds that are designed to last. The company offers a 15-year guarantee on all its bifold doors.

3. Good for the environment

Because wood is a natural material, it requires less manufacturing compared to synthetic materials like uPVC. Less manufacturing means less carbon dioxide, which lowers your carbon footprint. Wooden doors are biodegradable and can be responsibly sourced. All of Vufold’s timber door are FSC approved meaning they only use responsibly sourced materials. Vufold are fully CE marked meaning they are compliant with environmental, health and safety protection requirements.

4. Increased light

Classic bifold doors are fitted with glass. When used as a room divider, you are giving sunlight a wider entryway into both rooms.

5. Specifically designed for internal use

Often, internal aluminium and UPVC bifold doors are repurposed external doors fitted inside. This means they are often over-specified, oversized and overpriced. Vufold’s timber internal bifolds are specifically designed to be fitted in your home.

6. Increased space

Turn two rooms into one with a sliding bifold partition. For example, you could turn your kitchen and dining room into one large area for parties or social events.

7. Open plan or closed plan

Large open plan spaces can be great for parties but difficult to live with for day-to-day activities. Using internal bifolds as a room divider means that you can have the best of both choose between open-plan or closed plan.

There are several benefits of using internal bifolds to give yourself open and closed plan options. You can find out more by visiting our case studies.

8. Sound absorption

Wood absorbs sounds which can help significantly reduce noise levels for additional comfort.

9. Can be installed without a threshold

Vufold’s internal timber bifold doors are either side or top hung, they feature low thresholds that can be easily made to the same level as your flooring. Alternatively, some sizes can even be fitted with no threshold at all giving you seamless flooring throughout.

Wooden internal bifolds—door designs

In this section, we’ll look at Vufold’s range of internal folding doors. The doors can vary in size, and design, so it’s worth taking the time to consider what type of bifold door you require for your home.

inspire bifold door

Inspire

Inspire is a brand-new concept in internal bifold doors. Its unique design allows the doors to fold 180 degrees against the wall. This maximises the size of the opening itself as the doors aren’t stacked within it, they also don’t stick out into the room causing an obstruction.

A Single door can be opened for easy access or by using the simple to operate slide bolts all the doors opened and folded out of the way (see video for example).

Inspire comes in two styles:

  • Unfinished oak
  • White

Wooden internal bifolds—sizes and specifications

There are several styles of wooden bifolds, so it comes down to a balance between your personal taste and some practical decisions. Your personal taste may dictate the finish and colours while the interior space you have available will decide the doors’ width and number of panels.

Width

The width of your bifolds is determined by the wall size and the space available. Vufold makes bifolds with widths ranging from 1.2m (double door) to 3.6m (5 door).

How to measure for bifold doors

You can easily measure your aperture for bifolds in three easy steps:

  1. Measure the width at three separate levels (bottom, middle, top)
  2. Measure the height from top to bottom at three separate places (left, centre, right)
  3. Subtract 10mm from the smallest measurements (to ensure there’s enough space to fit the bifold and the frame)

To check whether the aperture is a perfect square, measure the diagonals from corner to corner.

Number of doors

The number of door panels your bifolds require depends on the width of the door opening. The wider the space, the more doors you need. Standard wooden internal bifolds have 2–5 doors. 6+ doors are available for bespoke purchases.

Glass

All Vufold’s wooden internal bifolds use single glazed 4mm toughened safety glass. Every pane of glass is compliant with European standards BSEN12150 and BSEN12600.
