Deciding between PVCu and Aluminium Bifolds

The significant benefits of aluminium bifolding doors are slimmer lines, less visual bulk, larger panel sizes and an overall more reliable product long term. It’s for these reasons that many PVCu double glazing companies choose not to supply PVCu bifolds alongside their window ranges. 

A PVCu folding sliding door is vastly improved on early generation products and provides a low-cost option. However, thick profile dimensions, bulkier hardware and greater thermal expansion are characteristic of the product. Aluminium bifolds are significantly more reliable.

Aluminium bi-folding doors can be made larger and taller than their PVCu counterparts.  In aluminium, bifold doors have far less obtrusive and more attractive hardware. They can also last much longer.  Furthermore, their slimmer sightlines, especially since the doors are closed most of the year, enable larger glass areas compared to pvcu.
