Advantages of uPVC bifold doors

Strong and durable

Bear in mind that if uPVC warps, the thermal efficiency can decrease.

Disadvantages of uPVC bifold doors

Can warp

Over time, after exposure to the sun, uPVC can start to warp. Not only can this affect the look of the doors, but it can stop them from opening and closing properly. Bear this in mind when choosing bifold doors, especially if you place them on a south-facing elevation as this can speed up the warping process.

May become discoloured

As well as warping, uPVC can discolour and fade after long-term exposure to the sun. uPVC frames also scratch more easily than aluminium.

Can look cheap

Also, the frames tend to be larger than aluminium or timber, so if you like the minimalist look uPVC may not be the best option.
