About Cortizo Bifold Doors
Cortizo bifold doors are slimline aluminium folding doors from the Spanish systems company Cortizo, built for wide openings in extensions, renovations and self-builds. The floor-to-ceiling panels run on tracks and fold left or right into a compact stack, so up to 90% of a wall can become a doorway. Each panel can be up to 1200mm wide and 3000mm high, and a set can run to 14 sashes. The lock system is tested to PAS 24, and the profiles take double or triple glazing with gaskets designed for weathertightness. Finishes include standard and RAL colours, dual colour and wood-effect powder coating.
As a Cortizo Official Fabricator, we make Cortizo bifolds to measure in West Drayton from Cortizo's own profiles, then supply and fit them across London, Berkshire, Surrey, Kent and Essex, or supply them only to installers and builders anywhere in the UK. The standard Cortizo Bifold has a 120mm sightline where two panels meet and a 104mm frame depth, and suits most rear extensions and garden openings. If you want slimmer meeting sections and lower U-values for a large or highly insulated extension, the Cortizo Bifold Plus has a 110mm central section and a 45mm thermal break, with U-values from 0.8 W/m²K. You can see working doors in our West Drayton showroom, open Monday to Saturday, 9:00 to 17:00.
