Considering how much bifold doors cost compared to other types, it might not surprise you to learn that the complex mechanism makes them quite a bit more costly. Nonetheless, our wooden bi-folding doors are available starting at €2,366.91. Our wood aluminium bifold doors have a base price of €4,599.35. Door prices depend on more factors than material, though: your patio door's size, triple or double glazing, and the number of door leaves, for example. Aspects such as the type of timber used, the colour or how many and which kinds of bifold door fittings you choose have less of an impact on how much your new bifold doors will cost, but these aspects are still noteworthy.
