Aluminium or uPVC Bifold Doors: Which Should You Choose?

You're in the market for a new door and you're wondering if material really matters. We get it. Both aluminium and uPVC bi folds have double glazing, great security features and offer thermal efficiency. So what are the real differences between these materials and should you pick uPVC or aluminium? 

 We're here to help. We'll explain the main differences between the materials and answer your common questions about these two types of folding door. We can help you to understand which one will work best for you and your home. Let's get straight to it.

 Aluminium bifold doors are considered better than uPVC bifold doors due to their longer lifespan. While aluminium bifold doors can last up to 45 years, uPVC doors typically have an average lifespan of only 20-30 years. Experts agree that aluminium is a more durable material, providing longevity and requiring less frequent replacement. 

 However, this doesn't always mean that aluminium bi folds are right for you. Choosing a bifold door is all about your needs, wants and budget and that won't be the same for everyone. With our years of experience helping our customers to find doors they love, we'll help you weigh up the pros and cons of uPVC and aluminium bifolds so you can make an informed choice and get the best material for your home.

Bi folding Doors with Aluminium Frames: The Lowdown

Aluminium bifolds have metal frames that are powder coated to give them a low maintenance and incredibly strong finish. If you're considering choosing aluminium bifold door then here's the scoop, we'll tell you everything you need to know to make the best choice for your needs.

Are aluminium bifold doors more expensive than uPVC? 

 Yes, aluminium bifold doors are generally more expensive than uPVC doors. However, bifold doors with uPVC frames are a more cost-effective option due to their lower price point. It's important to consider that uPVC bifold doors may need replacing sooner as they are not as durable as aluminium doors.

 Yes, aluminium bifold doors are secure when you take proper precautions. They can be just as secure as traditional patio or French doors, or even more so. With the right security measures, you can have peace of mind with aluminium bifold doors.

Are aluminium bifold doors cold? 

 No, bifolding doors in aluminium are not cold. In fact, they can help keep a room warmer. Building Regulations Part L now requires windows and doors to have a U-value of 1.6 W/m2K, which helps improve insulation. Unlike older regulations that allowed for a higher U-value, modern bifold doors are designed to retain heat and increase energy efficiency. 

 So although aluminium isn't a natural insulator, when it's used in doors it uses a polyamide thermal break. Thermal breaks are typically composed of rigid polyamide or polyurethane materials that have low thermal conductivity. 

 Despite the sound of the name to the uninitiated, a thermal break is not bad. It is actually very beneficial. When properly designed, these thermal barriers significantly reduce heat flow and help maintain connection surfaces above the dew point. This makes thermal breaks effective in preventing condensation and enhancing energy efficiency.
