About Cortizo Bifold Plus Doors
The Cortizo Bifold Plus is Cortizo's higher-performance bifold door, combining slim sightlines with stronger thermal insulation than the standard Cortizo Bifold. Its central section is just 110mm, so more of each opening is glass, and a 45mm thermal break brings U-values down to 0.8 W/(m²K). Sashes can be up to 1200mm wide, 3000mm high and 120kg, and take glazing from 25mm to 48mm thick, so it suits large, well-insulated extensions and new builds. The system is tested to PAS 24. We make each set to measure and install across London and the South East.
Choose the Bifold Plus over the standard Cortizo Bifold when insulation and glass area matter most: its 110mm central section compares with the standard system's 120mm sightline where two panels meet, and the 45mm thermal break brings U-values down to 0.8 W/m²K. Both take sashes up to 1200mm wide and 3000mm high. As a Cortizo Official Fabricator we make the Bifold Plus to measure in West Drayton, and supply it only to installers and builders as well as supplying and fitting it.
