How To Measure

Step 1 – Measure the Structural Opening Width
Measure the width of the opening in three places: at the top, middle, and bottom. Record the smallest of the three measurements, as this is the critical size your door must fit within.

Step 2 – Measure the Structural Opening Height
Measure the height from the finished floor level to the underside of the lintel in three places: left, centre, and right. Again, use the smallest measurement to ensure the door will fit without obstruction.

Step 3 – Check for Squareness
Measure diagonally from corner to corner in both directions. If the measurements are the same, the opening is square. If not, note the difference, as this may affect installation tolerances.

Step 4 – Confirm Threshold Type
Decide whether you want a standard or low threshold. This can affect the final door height, so it’s important to allow for floor finishes and drainage where applicable.

Step 5 – Allow for Installation Tolerances
Typically, a small fitting tolerance (usually around 10mm in width and height) is allowed for installation and adjustment. Your final order size should be the structural opening minus the recommended fitting clearance.

Step 6 – Choose Your Configuration
Confirm the number of door panels, opening direction, and stacking arrangement, as this determines track layout and overall frame design.

Step 7 – Double Check All Measurements
Re-measure everything before ordering. Accurate measurements are essential to ensure your Korniche Bi-Fold Door is manufactured to fit perfectly and installs smoothly.

FAQs

Please read our FAQs page to find out more.

What is ‘self clean’ glass?

Self-cleaning glass combines advanced self-cleaning technology with solar control performance, making it a highly desirable option for homeowners seeking premium glazing solutions. A specialist coating is applied to the glass surface, designed to actively break down organic dirt while reducing the adhesion of inorganic particles.

When exposed to rainwater, droplets spread evenly across the glass to form a smooth sheet rather than beading. This process lifts and carries away loosened dirt as the water drains from the surface, significantly reducing maintenance requirements. The result is clearer glass, less frequent cleaning, and a visible improvement in appearance that delivers lasting performance you can see.

Why is clip in bead important and why is it better than wedge gasket?

Our patented clip bead is used on our bifolding doors to retain the glass units in the sashes. The traditional method of retaining glass in aluminium glazed products is to locate an aluminium bead profile and pre load it with the use of a wedge gasket. Essentially there is enough room to locate the bead profile in the sash and then a wedge gasket is fitted to take up the gap and means the bead cant be removed. This is time consuming and fiddly and the result isn’t always as consistent in terms of appearance as some might hope. The patented clip bead we developed has a pre fitted gasket and utilises a plastic clip element that enables the bead to be clipped in incredibly easily and quickly. The result is not only neat and the sightlines consistent but also saves your installer a large amount of fitting time.

Why might I need ‘kit form’?

As a standard, our bifolding doors are preassembled before delivery. The doors only need to be fixed into position and the glass fitted. However, we can supply the doors in kit form if required. This means the outerframe is in four pieces and the sashes packaged up separately. There are various reasons why doors might be required this way but some of the main reasons are down to restrictions on access. For example, if the doors are being fitted in a property where there is no route to the intended location except through the house, then kit form would be a viable way of achieving this.

Which door styles are best and what is a traffic door?

Most people want the option to have one of the sashes that can be used as an everyday access door instead of having to fold at least two sashes together to get in and out of the property. This access door is known as a traffic door. It has a more traditional lever / lever handle fitted to it and has the locking barrel incorporated. For more information on which styles incorporate a traffic door, look in the bifolding door section.

What are the benefits of the anti backdrive feature in the shootbolt handle?

Usually unless the shootbolt is locked then it remains possible to force the shootbolts up with a jemmy bar from the outside and on doors with out a traffic door, this means the doors can be opened and access can be gained to the property. We engineered a unique feature into our shootbolt handles that means in their closed position they physically cant be back driven from the outside. This means that although there is the added piece of mind from the key operated shootbolt lock, it isn’t required to keep your property safe and secure.

Can I have trickle vents in the bifolding door, and do I need a frame extender to the head of the door to allow for them?

New build extensions usually require trickle ventilation to comply with building regulations. It is always best to ask your preferred installer or building control officer about this and how much trickle ventilation is required. Our trickle vents can provide 2500mm2 each and we can offer up to 3 vents in each door set.

In most other bifolding door systems the trickle vent is usually housed in a frame extender that is fitted to the top of the door. This is both unsightly and adds additional cost and so we developed our system to allow trickle vents to be fitted directly into the head of the door outerframe.
