Size related and other FAQs

  • Q:  Can I couple a window to the top of the door?
  • A:   No. A steel lintel must be installed above the door, then additional glazing can be fitted above the lintel.
  • Q:   Can I install a door in a conservatory?
  • A:   Yes, subject to confirmation from Slide and Fold Ltd. Please do not order a door until you have verified with a slide and fold representative, the size of the door, type of conservatory frames and roof system. For very large doors the door must be fitted within a structural goalpost, that is capable of supporting your roof and the load of our doors. Please seek our advice. We highly recommend that you consider our window frames and roof system, as they are designed for this purpose.

Open In or Out?

Most people base their choice on the requirement for space,either to the inside or outside. Doors are designed to be either wholly Open In or Out and there is no key benefit from choosing one over the other. It remains a matter of choice only. However there are some minor differences:


Open In:
  • Doors require room space when open.
  • Bifold PLUS doors can be buried 70mm to allow just a 16mm PVC up stand.

Open Out:
  • No internal room space required.
  • Threshold can be buried to a maximum of 10mm.
  • Achieves a higher pascal weather rating as wind pressure pushes door sashes tight against patented weather seals.
  • Open Out doors are 75% of all doors supplied.

Is your door for an extension ? :

  • All our doors are made to trickle vent for bifold plus doorsuch a high specification, they automatically conform to the current building (PART L) regulations. The only other consideration is if trickle ventilation is required.
  • All habitable rooms require 5000mm sq. of equivalent air.
  • If you have no other means of venting your room ( i.e. a brick vent, mechanical ventilation or another door or window with a trickle vent fitted) then a trickle vent will need to be fitted to your bi-fold door.
  • If a trickle vent is required it will be fitted to the top of the first and last door sash.

Is your door a replacement ? :

  • If you are replacing an existing door and not changing the structural width of your opening then building regulations do not apply.
  • If the door you are replacing has trickle ventilation already fitted, then it is a requirement that a trickle vent is fitted to the bi-fold door.
  • You may choose to have a vent fitted regardless of if being a requirement, to aid background ventilation.

Neutral Self Cleaning Glass:

  • Self-cleaning glass uses a microscopic coating with a unique dual-action. The first stage is "photocatalytic" - the coating reacts with daylight to break down organic dirt.
  • The second stage is "hydrophilic" - instead of forming droplets, rainwater hits the glass and spreads evenly, running off in a "sheet" and taking the loosened dirt with it, also drying quickly without leaving streaks.

Blue Solar Control Self Cleaning Glass:

  • Solar control glass can be used to minimise solar heat gain and help control glare. In temperate regions, it can be used to balance solar control with high levels of natural light. Solar control glass is ideal for large folding doors where solar heat gain could be an issue.
  • This attractive blue glass ,combines dual-action, self-cleaning properties with solar control performance for a cooler internal environment. Specially designed for the optimum unit ideal for folding doors. It uses daylight and rainwater to breakdown and wash away organic dirt from exterior surfaces. Its unique blue colour also helps keep internal temperatures cool whilst still maintaining excellent light transmittance.
