Which is better, uPVC or aluminium bifold doors?
Aluminium is usually better for bifolds because it is stronger, allows slimmer frames and handles larger, heavier leaves. uPVC is cheaper, lighter and naturally insulating, so it suits smaller openings and tighter budgets. Match the choice to the span and the customer’s budget.
How do the two compare for trade buyers?
| Feature | Aluminium | uPVC |
|---|---|---|
| Strength | Higher, handles large leaves | Lower, bulkier frames |
| Weight | Light for its strength | Lighter, gentler on hardware |
| Thermal | Thermal break needed | Naturally insulating |
| Finish | Powder coat, wide RAL range | Fewer colours |
| Life | Often quoted 30+ years | Generally shorter |
When should you specify aluminium?
For wide spans, heavy glass, slim sightlines and dark or dual colours. Check the thermal break and Uf values.
When should you specify uPVC?
For smaller openings, lower budgets and jobs where low maintenance and easy handling matter. MLI Building Products supplies aluminium bifolds and uPVC ranges to installers.
What does the customer usually ask about?
Cost, colour and sightlines. Aluminium wins on colour and sightlines, uPVC on cost. Check the data sheet for the Uf value, as both materials can meet current thermal requirements when specified properly.
