- Prepare your sill: apply a small amount of silicone to the rebate in the top part and then simply, push the two parts together.
- Drill: the next step is to drill your pilot holes (each bifold door will come with specific measurements unique to our doors here at ATT Fabrications) ensuring you drill them through the three fixing holes. They can be found on the underside of the sill.

- Assemble the frame: wood screws and gaskets are a necessity for this section. Make sure that your silicone sealant is to hand so that you can apply some to each of the head assembly, both sides of the tenon and finally the mill end of each jamb assembly.
- Once you have done this, you need to make sure that you fix the jamb assembly to the head assembly.
- Slot the tenon into the end of the jamb assembly and screw them together.

- Frame fitting:nafter all of those fiddly and intricate steps, it’s time to fit your frame.
- This is likely to be a two person job, so guide the frame into the designated area.
- Adjust your frame’s position to make sure that the fixing holes in the head track are in the perfect position.
- Now, move the frame head to allow for any pre-drilling that needs to be done which is above the lintel which subsequently will need to be drilled through the holes in the lintel.

- At this point in the process, you should be ready to fix the head.
- The exterior fittings need to be attached to the head in stages; start with the two outer fittings and lighten the fixing screw a little bit tighter (be careful not to over tighten).
- Then, carefully tighten the central screw so that the head and lintel are nearly touching.
- Moving onto the jambs (and working from the outside in) again, lightly tighten the screws ensuring that you vary the packing between the head and the lintel in order to create an upward curve towards the head.
- Once you’ve achieved your desired curve, tighten the screws where appropriate.
