Bi-fold doors vs patio doors – which is the best for energy efficiency?

Bi-fold doors and sliding patio doors are both popular door options for UK homeowners. They are both excellent options for connecting indoor and outdoor areas, and both door types come with high security multi-point locking systems as standard. But what about their energy efficiency performance? Let’s take a closer look.

The importance of energy efficiency

Improving home energy efficiency is one of the most important considerations for UK homeowners today. Modern energy efficient glazing, like the units used in SEHBAC’s windows, doors, and conservatories can have a huge impact on your home’s thermal performance. New windows and doors provide homeowners with a wealth of benefits. These include:

  • Better insulation
  • Reduced heat loss
  • A more comfortable living environment
  • Lower heating bills
  • Decreased carbon emissions

Thermal efficiency is also a significant factor for everyone in the glazing and wider construction industry. With government targets to reduce carbon emissions to net zero by 2050, increasingly strict regulations have been introduced across the building industry. With regards to replacement windows and doors, they must now achieve higher standards of energy efficiency than ever before.

What are the best doors for energy efficiency?

When it comes to improving energy efficiency, both sliding patio doors and bi-fold doors are an excellent choice. To gauge which door type is the best for boosting thermal performance the most important factor to consider is the material. At SEHBAC, we install aluminium bi-fold doors and both uPVC and aluminium sliding patio doors.

When directly compared, uPVC is the more energy efficient option. With U-values as low as 0.9 W/m²K, our uPVC sliding patio doors are the most energy efficient option. They can even achieve an A++ rating on the energy efficiency scale.

When it comes to aluminium sliding patio doors vs aluminium bi-fold doors, the natural insulting capacity of aluminium means that the two door types are equal in performance levels. With U-values as low as 1.32 W/m²K, both models are an excellent choice for any home improvement project.

As you can see, when manufactured using the same material, there is no difference between the energy efficiency capacity of bi-fold doors and patio doors.
