Trickle Vents*
What are trickle vents used for?
If this is for an extension, please read below;
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 door or window.
If this is for replacing an existing door or window, please read below;
If you are replacing an existing door or window and not changing the structural width of your opening then building regulations do not apply.
If the door or window you are replacing has trickle ventilation already fitted, then it is a requirement that a trickle vent is fitted on the replacement product. You may choose to have a vent fitted regardless of it being a requirement, to aid background ventilation.
If you choose to have trickle vents on your door or window it will be cut out into the opening sash that you choose.
External cill*
External Cill
85mm Sub Cill
This compact cill has minimal overhang designed primarily for installations where space is limited, ideal for directing water away from the building façade and ensuring effective drainage in smaller setups.
150mm Sub Cill
The 150mm cill is commonly used across residential and commercial installations. It provides enhanced protection by directing water further away from the wall surface, helping prevent moisture accumulation.
180mm Sub Cill
The 180mm cill has a generous overhang, ideal for installations that require robust weatherproofing. This extended overhang is particularly suitable for high-exposure areas, offering superior water deflection.
