Single casement door

The ‘traditional’ hinged door design, with modern performance and style

A single casement door , also known as french door, is similar in concept to a casement window where a single hinged sash (opening door leaf within a frame) opens outward, often to a patio, garden, deck or balcony. Casement doors are widely used throughout UK as a simple but efficient way to connect the inside with the outside.

VELFAC composite windows and doors bring together the best of both worlds; the durability and versatility of aluminium and the beauty and warmth of natural wood.


Description and benefits

Casement door (French door)

VELFAC single casement patio doors are often also used to replace single windows in renovation projects. Replacing a window with a patio door increases the amount of light into a room and open up your home to the outside. The sash stops at 90°, but is also available with 180° hinge which allows the sash to fold back flat against the wall.


The ease and simplicity in handling and operating these types of doors make them a very popular choice amongst homeowners today. Furthermore, owing to their sturdy construction and slim frame, VELFAC single casement doors help you create architectural features with no visible difference between for example opening doors and fixed windows. The slim frame also allows more light into the rooms, reducing the need of artificial light and providing a feeling of wellbeing.


Built with highest quality materials, our casement doors are made to last. The external aluminium requires virtually no maintenance, while the internal wood insures high levels of insulation.



Design without compromising on security

VELFAC casement doors offer exceptional insulation, while the slim frame also allows maximum daylight and ‘free’ solar heat to enter the interior - with low emissivity glass coatings available to control solar gain. Accredited by the UK Police in their ‘Secured by Design’ initiative, VELFAC casement doors offer impressive security features such as multi point locking mechanisms and internal glazing beads, used to prevent the external removal of glass.
