Bi-Fold Doors

Open up to a world of possibility.

Durable bi-fold doors from Coastline Architectural Windows 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.
