While considering bifold doors for your home improvement project, one of the first questions that may be on your mind is the size of the opening that’s required. With numerous combinations of opening sizes and panel numbers, we take a closer look at options in our latest blog article.

Small Bifold Doors – What is the minimum opening?

The minimum width for small bifold doors is 1400mm. And the configuration would consist of two door leaves, both matching in size of 700mm.

Is there a Maximum Width for Bifold Doors?

Solarlux bi-fold doors offer unlimited width and can be designed to the exact dimensions you require, not so much as maximum width but maximum panel sizes depending on the size of the aperture and which door system you choose. For more info on our range of Solarlux Bifold Doors, Click Here.

Bifold Door Materials

Solarlux offers a choice of high-quality aluminium, timber and composite Bifold doors ranging in various configurations.

Wooden bifold doors are a popular choice for Self-builders, architects and homeowners of Barn conversions, period homes and properties in conservation areas. They offer warmth, beauty and sought after addition to extensions for Victorian terraces and traditional cottages.

Aluminium remains the most popular choice for bifold doors. A lightweight and robust material that is 100% recyclable. Aluminium bi-fold doors are usually comprised of aluminium profiles sandwiched around what is known as a polyamide thermal break – a strip of rigid insulation material.

With a focus on minimalism, the industry-leading Highline and Ecoline aluminium Bifold door systems offer one of the slimmest profile bifold doors on the market.

Composite Bifold doors, the beautiful engineered timber-clad aluminium bifold doors blends the high performance of aluminium with the natural warmth and beauty of wood.
