10th July 2025

Aluminium bi-fold doors are a strong, stylish choice for changing homes and businesses. These doors offer a stylish design, great functionality, and lasting performance. They’re perfect for both home improvements and commercial projects.

Why should you consider them for your project? There are so many reasons to choose aluminium bi-fold doors. Not only do they boost security and save energy, but they are also versatile and easy to maintain.

In this blog, we’ll explore four key reasons to choose aluminium bi-fold doors.

1. Excellent Security for Peace of Mind

Security is a critical concern for homeowners and trade professionals alike. Aluminium bi-fold doors provide excellent protection, making them perfect for homes and businesses.

Key Security Features

• Robust Aluminium Frames: Aluminium’s strength ensures high resistance to break-ins compared to wood or uPVC.
• PAS 24 Certified: Our doors are built to meet the highest security standards.
• Multi-Point Locking System: Provides multiple layers of security to prevent forced entry.
• Shoot-Bolt Locks on Mullions: Further enhances security by locking additional door sections.

Alimax’s aluminium bi-fold doors comply with the latest UK security standards. PAS 24 doors meet the Secured by Design (Police Preferred Specification) and offer a solid way to secure homes and businesses. With these doors, you can rest assured that your property remains secure without sacrificing design.

2. Exceptional Thermal Efficiency & Energy Savings

Aluminium bi-fold doors are known for their energy-efficient properties. Despite large glass panels, these doors can maintain a comfortable indoor temperature year-round.

Key Thermal Features

• Thermal Break Technology: Reduces heat transfer between internal and external environments.
• B-Rated Energy Glass: Standard glazing ensures excellent insulation.
• Polyamide Thermal Breaks: Prevents heat from escaping in winter and keeps interiors cool in summer.

These features lower the need for heating and cooling. That makes them a wise investment for saving energy in the long run.

Alimax’s aluminium bi-fold doors use at least B-rated energy-efficient glass. This helps improve insulation even more and also follows Building Regulations. Thus, ensuring your project meets energy efficiency standards, whether it’s for a home or a commercial space.

Energy Saving Trusts’s guide on energy effecient windows and doors shows how energy-efficient doors can cut costs. Doors with a thermal break are a great option to help meet building regulations.

3. Versatility & Customisation for Any Project

Aluminium bi-fold doors are very versatile. They are perfect for many projects, from home extensions to commercial buildings.

Customisation Options

• Multiple Configurations: Choose from internal or external folding, single or multi-panel options.
• Varied Sizes: Doors can be custom-made to fit any aperture.
• Slimline Frames: Allow for larger glass panels and unobstructed views.
• Wide Range of Colours and Finishes: Tailor the door’s appearance to suit your style and project needs.

Alimax provides many customisation options. You can choose different panel sizes, internal or external folding, and a variety of colours and finishes. Whether you need a sleek, contemporary look or a more traditional design, we tailor each door to suit your project perfectly.

4. Increased Durability & Low Maintenance

Aluminium bi-fold doors last long and need little upkeep. This makes them a competent and dependable choice for any project.

Key Durability Features:

• Weather-Resistant Frames: Aluminium does not rust, corrode, or warp. This means it lasts well in harsh weather.
• Low Maintenance: Unlike timber, aluminium does not require regular painting, staining, or sealing.
• High-Performance in All Conditions: Aluminium doors perform well in all weather, whether near the coast or inland.
