The following are guidelines for you to make your own judgements about the best exit from your house and to help specify your fire escape ladder requirements.
Choose a window in a bedroom (not on the landing since smoke will often rise up the stairs), ideally from the persons room who will need the most help (e.g. Children).
If there is an alternative, choose the window with the least height to the ground. If possible avoid windows which have other windows directly below them on the route to the ground.
Vertical Drop Normal Window. Measure length from outside sill to the ground using a 'plumbline' (weight attached to a piece of string) or otherwise a tape measure through the inside of a house.
Sloping Roof Window e.g. Velux. Again use a plumbline from the bottom of the window to the ground. Alternatively, measure from the roof window to the edge of the roof using a tape measure and add it to the remaining vertical drop, which can be measured internally through the inside of the house.
Important. Please measure the length carefully so that we can provide you with a ladder that meets your requirements.
The X-IT Ladder is appropriate for escape down vertical walls of any height up to 25ft (7.6m). The adjustable frame (see diagram below) is designed to hook over a wall up to 20 inches (51cm) thickness.
The 'Rollo' Ladder will fit all other situations and is available in 5ft lengths up to 40ft (12.2m). The 'Rollo' is designed to fit unusual escape situations, for example:-
The Rollo escape ladder is fitted with the same frame as the X-IT fire escape ladder. On the rare occasion that the frame will not fit your window correctly, the frame can be detached and instead an 'eyebolt package' can be ordered and fitted. The eyebolts are fitted into the main wall inside and below the window or into a main roof timber.
