Bi-Fold Door
Open up to a world of possibility.
Durable bi-fold doors from Portland Aluminium & Glass feature strong quad rollers – either top or bottom-rolling – that run on a matching double track. This means you can always rely on them to operate smoothly.
You can even think about combining them with a flush threshold to minimise the risk of trip hazards.
For optimal energy efficiency and noise reduction, we recommend double glazing or a thermally broken system.
