Raised edge trim for ARBOFLEX PU liquid roofing system.
The ARBOFLEX Kerb Trim is installed on roof edges where water must be retained and directed toward a designated run-off point rather than flowing over the edge.
Manufactured in GRP and colour-matched to the ARBOFLEX system, it forms a built-in upstand at the roof perimeter and integrates directly into the reinforced membrane.
Supplied in 2.5 metre lengths, each trim includes one joining clip.
Application ▸
- Non-draining roof edges
- Perimeters where water must be diverted
- Roof layouts using designated drip edges
- Projects where a separate timber upstand is not required or desired
The kerb trim works in conjunction with ARBOFLEX drip trims to control drainage direction across the roof.
System Integration ▸
The kerb trim is installed in the same manner as the ARBOFLEX drip trim:
- Mechanically fixed into the deck (pins sold separately)
- Bedded with a bead of ARBOFLEX PU Sealant at the rear
- Reinforced using ARBOFLEX PU liquid and 225gsm matting feathered onto the pinned return
This ensures fixings are encapsulated and the trim becomes part of the waterproof membrane.
Corners & Joining ▸
- Each trim includes a joining clip for straight runs
- 90° kerb-to-kerb corners use the ARBOFLEX Kerb Corner
- Kerb-to-drip transitions at 90° use Left Hand or Right Hand Corner pieces
Specification ▸
- Length: 2.5 metres
- Kerb Height: 110mm
- Material: GRP
- Colour: Grey (matched to ARBOFLEX PU UV Protect)
- Compatible With: ARBOFLEX PU, 225gsm reinforcement matting & UV Protect
Summary ▸
The ARBOFLEX Kerb Trim provides a raised perimeter edge for non-draining roof sides within the Arboflex PU liquid roofing system. Fully integrated into the reinforced membrane, it forms a secure and durable edge detail while directing water toward designated outlets.
