UAC V-Ridge is an injection moulded, autoclaved, multi-thickness
fibre-cement (asbestos-free) product made with Portland cement and
ground silica reinforced with cellulose fibres. Whilst it has been
developed as a ridge capping for slate roofs, it can also be used
on roofs installed with fibre cement shingles, shakes or corrugated
V-Ridge comes in a range of four different ridge angles, i.e. 90,
105, 120 and 135 degrees to fit most roof slopes. The standard size
of V-Ridge is 600 mm long, 175 mm wide each side of the "V"
and its nominal thickness ranges from 5 mm at its thinner section
to 12 mm at its thickened reinforcements. Each ridge is light, ighing
only about 2 kg.
UAC V-Ridge is currently available in two standard textures:
- Black (Natural base colour coated with clear primal)
- Blue (Pigmented grey base, coated with greyish black primer
and quality top coat to assure an aesthetic and long lasting finish
against flaking and uneven discolouration).
Several innovative features are integrated into the UAC V-Ridge
to provide functional advantages and advantages and distinctive
benefits over other convential fibre cement "V" types.
These special features are illustrated below:

reinforcements enhance product bending and breaking strength
during handling and fixing
slots facilitate water run off
authenticates UAC product and facilitates ridge angle
skirting (with deeper incline) accomoadates offsets &
tolerances of roof structure along ridge line.
Reinforcement reduces the distance between ridge supports on underlying
purlins/battens for improved seating and stability during installation.
V-Ridge Fixing Recommendations:
Install roof structure and roofing sheets in accordance with
the manufacturer's recommedations and provide necessary battens
for fixing of V-Ridge as shown in figure1.
Lay the first piece of V-Ridge (as a starter ridge) with
its non recessed end at the starting end of the ridging line
of the roof. (For use as hipped ridge, ensure that the recessed
end of the starter V-Ridge is always pointing upwards towards
the line of ridging).
the second V-Ridge on the first, followed by successive V-Ridges
in lapping configuration along the ridging line.
Drill and screw the starter V-Ridge and successive V-Ridges
into the ridge battens with 50 mm x 6.3 mm self sealing screws
(recommended) at fixing positions as shown in figure 1 and
figure 2. Ensure proper alignment of V-Ridges during the laying
and fixing operations.
Shorten the final V-Ridge at the stop end of the ridging
line as necessary. This may include the removal of the recessed
end of the V-Ridge. Depending on the remaining length of the
cut-off V-Ridge at the stop end of the ridging line, fix enough
screws on the finishing V-Ridge to prevent ridge-end uplift.
