Key Features of Our 2.5m Aluminium Bi-Folding Doors

The 2.5m aluminium bi-folding doors from TWR Group combine sophisticated engineering with practical, user-centric design to cater to a wide range of applications. Below are the distinctive features that set our doors apart:

Slim Sightlines:

Our bi-fold doors are designed with narrow frames to maximise glass area, ensuring a sleek and contemporary aesthetic. This feature allows for more natural light to enter the space, enhancing the ambiance and perceived size of any room.

Thermal Efficiency:

Each door is constructed using a thermally efficient system that can achieve a U-value as low as 1.5W/m²K. This insulation performance not only helps in maintaining comfortable indoor temperatures but also reduces energy costs.

High Security:

Security is a critical aspect of our bi-folding doors. They are equipped with robust shoot-bolt locking mechanisms and internally beaded frames to prevent glass removal from the outside, offering peace of mind and enhanced safety.

Versatile Installations:

Our doors are suitable for a breadth of environments, from private residential properties to commercial spaces. They provide flexible design solutions with various panel configurations and the ability to fold and stack compactly, either inward or outward, to tailor to specific spatial requirements.


Manufactured using high-quality aluminium, these doors resist weather elements and wear, maintaining their function and appearance over years of service. Aluminium’s natural strength allows for larger doors with less material, preserving views and integrity.

Finish and Colour Options:

With our in-house powder coating facilities, we can customize the colour of your doors to match any palette. The finish is not only aesthetically pleasing but also serves as a protective barrier against corrosion and wear.

Easy Maintenance:

Aluminium doors require minimal upkeep due to their resistance to rust, rot, and distortion. Regular cleaning with simple household products will keep them in optimal condition.

Seamless Transition:

With the capability to create expansive openings, our bi-folding doors facilitate a seamless transition between indoor and outdoor spaces, making them perfect for integrating patios, gardens, and balconies with interior living areas.

Exploring Bifold Doors: Insights and Enquiries

What are some frequently asked questions about bifold doors?

Welcome to our FAQs section about Bifold Doors, where we'll provide you with valuable insights and information about the perfect solution for enhancing indoor-outdoor connectivity and maximising natural light intake. Discover the benefits of bifold door systems and how TWR Group offers quality aluminium bi-fold doors solutions for trade and commercial projects.

What are bifold doors, and how do they differ from traditional doors?

Bifold doors, also known as bifolding doors, are a type of door system that consists of multiple panels connected by hinges. Unlike traditional doors that swing open and close on a fixed axis, bifold doors slide and fold to one or both sides, creating a wide opening. This design allows for a seamless transition between indoors and outdoors, making them an ideal choice for spaces that require an open and spacious feel. The innovative bifold door system provides a perfect solution for connecting living spaces with patios, gardens, or balconies, offering an unobstructed view of the surroundings and bringing in abundant natural light.

What are the benefits of installing bifold doors in a property?

Bifold doors offer numerous advantages that make them a popular choice for homeowners and businesses alike. Some key benefits include:
Maximised Natural Light: Bifold doors feature large glazing areas that allow ample sunlight to enter the interior, brightening up the living space and reducing the need for artificial lighting during the day.

Improved Indoor-Outdoor Connectivity: The folding mechanism of bifold doors enables a smooth transition between indoor and outdoor spaces, creating a sense of continuity and providing an inviting atmosphere for gatherings and events.

Enhanced Space Efficiency: Bifold doors fold neatly to the side, taking up minimal space compared to traditional doors. This makes them an excellent choice for smaller rooms or areas where space optimisation is crucial.

Energy Efficiency: Quality bifold doors, like the ones offered by TWR Group with a U-value as low as 1.5W/m²K, provide excellent thermal insulation, reducing energy consumption and lowering utility bills.
