Why choose our UPVC bi fold doors

Add light and space to a project

Contemporary UPVC bi fold doors combine elegance with flexibility, allowing design of panoramic view wide-span door openings to create versatile spaces.

Bi-fold doors are precision engineered to the highest standards and available in a variety of finishes and folding leaf combinations. PVC-U door sashes slide along a thermally-broken aluminium top and bottom track system, designed to ensure years of trouble free service. Rigid aluminium tracks increase the structural strength and enable easy transportation, preventing excessive flex to ensure that the doors run smoothly, even on long spans with multiple leaf configurations. Bi-fold doors are energy efficient and easy to maintain once installed.

While UPVC bi-fold doors come in various colours (see our options above) they can’t be easily painted due to their smooth surface. If you’re seeking a specific colour, it’s best to choose a door in that colour from the beginning, as painting might not yield desired results.

UPVC bi-fold doors are designed to fold in a space-saving manner. When fully opened, they create an accordion-like stack, maximizing the opening and providing a seamless connection between indoors and outdoors.

UPVC bi-fold doors come with adjustable hinges and tracks. If you encounter alignment issues or difficulty in operation, refer to the manufacturer’s instructions or consult our expert installation team who will be happy to help.

Altering the height of UPVC bi-fold doors is a complex process that usually requires professional expertise and may involve structural changes. We recommend contacting our expert team to discuss making alterations in more detail.

Well-maintained UPVC bi-fold doors can last for decades. Generally, you can expect them to have a lifespan of around 20 to 30 years or more, given their durability and resistance to weather.

The cost of UPVC bi-fold doors varies based on factors like size, design, and additional features. While they generally cost less than some other door materials like aluminium, the exact price will depend on your specific requirements.
