PP-3 available in standard sizes or bespoke
for site requirements.
Roof-Nek for small pipes, cables
and lightning conductor tape.
PP-3 & Roof-Nek penetrations for:
Pipes
Cable
Cable tray/ladder
Telecom feeders
Lightning conductor tape
Design principles:
Building clearance
Removable lid
Waterproofing
Roof-Pro risers are designed to allow the roofer unimpeded
access to safely form the waterproofing upstand, providing
a waterproof penetration with adequate "building clearance" from
the finished waterproofing level at the point at which the
services access the flat roof. Particularly important in refurbishment
situations, once installed by the roofer the riser is sealed
and watertight ready for the following M&E trades to access.
The lid is secure but detachable to permit following trades
easy access to the riser.
It is good practice to ensure no back fall into the riser.
The pipe or cable tray should be set down immediately passed
the units face to create a drip outside of the riser. If possible
orientate the riser opening away from the prevailing wind.
Check the effect of any roof gradient on the alignment of the
riser the opening should be facing down.
In order to advise on product selection
Roof-Pro will require:
Size and quantity of services i.e. pipe diameter including insulation
thickness, quantity and intended centres of pipes. Cable size bending
radius, cable tray/ladder size.
In order to advise on product installation
Roof-Pro will require information of the roofing assembly:
Deck type, insulation thickness, type of insulation, the waterproofing
membrane type and both insulation and waterproofing manufacturers details.
Approval of the waterproofing detail for guaranteed roofing systems is
to be sought from the membrane manufacturer.
PP-3
Available in three sizes to provide standard "off the
shelf next day" answers for typical requirements. It would
be recommended to fit the largest PP-3 leaving any spare capacity
compact for future use. Where restrictions dictate the other
sizes and profiles are available.
PP-3 1875 the largest PP-3 has
an aperture of 180mm high x 755mm wide. This unit is suitable
for a large number of refrigeration lines, cable tray/ladder,
or medium (four number 180mm including insulation and waterproof
lagging)- F&R pipes.

All PP-3 models come with an aluminium "pull
out panel". The panel is aluminium to allow on site
cutting to suit the services profile without corrosion
issues. The gap between the services and panel should be
kept to a minimum and caulked with a suitable filler or
glands and gaiters can be secured onto the aluminium panel.
This panel is important as it provides protection from
driven rain, seals the riser with regard to air pressure,
vermin and insects.

PP-3 3040 medium PP-3 has an
aperture of 300mm high x 400mm wide. This unit is suitable
for a number of refrigeration lines double stacked, cable tray/ladder,
or two number medium (175mm including insulation and waterproof
lagging)- F&R pipes.
PP-3 2020 small PP-3 has an
aperture of 200mm high x 200mm wide. This unit is suitable
for a number of refrigeration lines, cable tray/ladder, or
four number small (max 80mm including insulation and waterproof
lagging)- pipes.
Installation guide Roof-Nek
The Roof-Nek circular flange at the bottom is to be firmly
secured and sealed at waterproofing level.
Roof-Nek Bitumen systems: Check with
membrane manufacturer for approval.
The Roof-Nek is to be primed and allowed to dry where
bitumen membrane is to be applied. The underlay and cap sheet
should be bonded to the top of the Roof-Nek flange. If possible
a second layer of underlay can be positioned below the flange
with the Roof-Nek positioned above sandwiching the flange area
between two layers of underlay. The cap sheet flange piece
should be finished with the leading edge some way up the radius
bend between the Roof-Nek flange and vertical section. Flashing
a "felt collar" over the upturned base piece secured
with a mechanical strap (jubilee clip).
Roof-Nek PVC single ply systems: Check
with membrane manufacturer for approval.
The single ply waterproofing can be formed on site to
cloak the flange and vertical section. The top of the cloak
can be sealed with a suitable sealant and mechanical strap
(jubilee clip).
Roof-Nek PVC single ply systems: Check
with membrane manufacturer for approval.
Roof-Nek is available with a PVC coated flange that
the PVC waterproofing membrane can be bonded to.
Installation guide PP-3
The PP-3 flange at the bottom of the base section is to be
firmly secured to the roof deck.
PP-3 Bitumen systems warm roof: Check
with membrane manufacturer for approval.
The PP-3 is supplied primed where bitumen membrane is to be applied.
The Vapour control layer (VCL) is bonded to the PP-3 base flange and
up the base upstand. The "mid unit" base flashing is deep enough
to permit 80mm of insulation up the vertical of the base unit. Fix the
insulation to the upstand. The underlay and cap sheet should be fully
bonded the total height of the upstand. The "mid unit" base
flashing must cover the cap sheet by 50mm.
